NEW YORK (GenomeWeb News) – New research is casting doubt on the notion that there was extensive pre-Columbian trading between Polynesia and South America.

An international team of researchers sequenced mitochondrial DNA from 41 Chilean chickens and analyzed their phylogenetic relationships by comparing them with available ancient samples and with more than 1,000 modern domestic chickens from different parts of the world.

The results, appearing online this week in the Proceedings of the National Academy of Sciences, suggest that Chilean chickens share mitochondrial sequence with both Polynesian and European chickens, originating in the Indian subcontinent. As such, the new work fails to support — though it doesn’t disprove — the idea that there was pre-historic trade between early Polynesians and South Americans.

“Polynesians are known to have spread chickens across the Pacific at least as far as Easter Island, but were not thought to have introduced them to South America,” senior author Alan Cooper, director of the Australian Centre for Ancient DNA in Adelaide, explained in a statement.

But that didn’t stop some from speculating that there were chickens in America before the arrival of Spaniards in the 15th century. The presence of some unusual chicken breeds, including the Araucana and Passion Fowl, found in Chile fueled speculation that early Dutch or Polynesian traders had introduced chickens to the region before Columbus’ arrival.

And that theory was bolstered last year by research published in the Proceedings of the National Academy of Sciences linking chicken sequences at Chilean and Polynesian archeological sites. Based on their radiocarbon data and analyses of a short mitochondrial DNA control region, the researchers working on that paper concluded that there was a pre-Columbian introduction of chickens — originating in Polynesia — to the Arauco Peninsula in Chile.

For the latest study, Cooper and his team sequenced mitochondrial DNA from 41 different Chilean chicken breeds — 28 Araucanas, seven creole, one Japanese Long Tail, and five Passion Fowl — selected from a dozen sites within the country. They then compared these sequences with ancient Polynesian and Chilean chicken sequences and with roughly a thousand domestic chicken sequences.

When the researchers analyzed phylogenetic relationships between the birds, they found evidence that the proposed pre-Columbian chicken did share some sequence with Polynesian chickens. But, importantly, this sequence appears to have a worldwide distribution, removing genetic support for a direct relationship between Polynesian and South American birds.

“The results showed that the ancient Polynesian and Chilean chickens possessed a genetic sequence that is the most common in the world today, the so-called ‘KFC’ gene,” Cooper said. “This sequence would undoubtedly have been common in the early Spanish chickens, and therefore provides no evidence of Polynesian contact.”

In contrast, the team discovered an uncommon haplotype on Easter Island that is shared with chickens in the Indonesian islands and parts of Japan and the Philippines. So far, though, researchers have not detected the sequence representing that rare haplotype in Polynesia.

The team’s mitochondrial DNA analysis also provided evidence supporting the idea that European chickens originated in the Indian subcontinent and were dispersed to other parts of the world from there.

In the future, the team noted, more work will be necessary to determine the timing of chicken dispersal throughout and adaptation to the Americas and South East Asia. “Of particular interest will be chickens kept by some indigenous communities in the Amazon forest, the origins of which remain unclear,” they wrote.

I wonder if they are refering to the Rapa Nui chickens? They have black flesh and bones like silkies.

Good question, ~Ann. It cost me $10 to get access to the full length article to answer your question, but "inquiring minds want to know" ;)

The "uncomon haplotype on Easter Island" that is referred to comes from ancient chicken bones from archeological sites on Easter Island dating from around 1100 to 1400 AD. Their conclusion is that this ancient haplotype should have been present in the ancient chicken bones found in Chile if they were from Polynesian chickens, but it wasn't. They also were unable to find that haplotype in any other modern western Polynesian chickens. Even though not specifically stated, I would presume that they checked the Rapa Nui currently on Easter Island Their conclusion is that this ancient haplotype has been lost by later interbreeding with other types of modern chickens and thus isn't available to track chicken migration. That's unfortunate.

They also say that "If ancient Pacific/pre-Columbian chickens were the ancestors of the Araucana, traits such as blue/green-shells, ear-tufts, and/or rumpless might be expected to occur in some modern Pacific Island chickens. However, we are unable to find any reports that this is the case." Of course this begs the question of where and how these traits originated.

It all gets rather complicated, but the bottom line is that the jury is still out. I think that this controversy will promote the testing of lots of other native South American chickens in an attempt to get more definitive answers. And hopefully other archeological sites containing chicken bones will be discovered and tested. So we'll wait and see..... :?

There has been some discussion on the game bird and waterfowl website (http://www.gbwf.org) concerning Araucana back ground. Turns out someone here in VT has some founding breeds and possible ancient bloodlines including Crested Mapuche, Quechua, Rapa Nui and Quetero! I hope to get down to this person's place someday to have a look see.

There has been quite a bit of discussion about the pre-Columbian presence of the Araucanian hen of late.
The first reports were quite exciting - finally conclusive evidence that the doemstic fowl reached the shores of Chile well before Europeans.
It was considered to be one of the most important Archaeological stories of the year- and perhaps for some, even the century.
I encouraged Alice Storey to study the hapolotypes of the Oceania domestic fowl spread from Indonesia, through the Melanesian, Oceania and South Pacific archipelagos as this is a study that three generations of Japanese ethnozoologists had already undertaken - but never with the conclusive proof of an actual bone-their study was limited to interrelated links between various islands vegetable/fruit crops, pigs and chickens included - if they were of course present in each of the islands.
Ponape, Marquesis, Rapa and Easter Island all proved to be very important places for the Japanese team- because they discovered evidence that
the earliest settlers most prized possessions were special roosters - specifically hybrid roosters which held a certain symbolic/socio-religious significance to the semi-nomadic clans.




Later, after it was established that the chicken bones were in fact Pre-Columbian, the academics that always take the opposed view, the discovery was squelched because A. the detracting authors don't believe chickens arrived before Europeans,; B.are not aware of the hybrid male founders C. WOrked only with mtDNA vs haplotypey and Nuclear DNA which not only prove the evolutionary novelty of the Araucanian hens but also provide compelling data about their genetic origins which differ from those of other chickens.

I am posting a few important peer-reviewed papers that throw light on the significance of specific traits of certain domestic strains of chickens and from there, I hope that we can discuss the history of the domestication of the chicken as it relates to the migration of certain cultures across the oceans and which eventually resulted in the generation of the Araucanian Hens.

Please read these papers carefully so that we can begin to discuss the findings as they relate to the blue egg gene, rumplessness, tufts and so on and so forth.

Carotenoid genetics: Chicken skin sheds light on carotenoid genetics

M A Pointer1 and N I Mundy1

The conspicuous yellow or red carotenoid colouration found in many birds is surprisingly poorly understood from a genetic standpoint. Many studies have established carotenoid colouration as an honest indicator of male quality (Blount et al., 2003; Faivre et al., 2003; Blas et al., 2006) but the genetic mechanisms involved in metabolizing and depositing the pigments have remained elusive. This is unfortunate as genes controlling these processes could be potential keys to unlocking how sexual selection acts at a molecular level. A recent paper by Eriksson et al. (2008) has elucidated the genetic basis for the carotenoid trait in chickens and uncovered a mechanism for carotenoid allocation that is quite the reverse of what many would have expected.

The trait studied was the presence of yellow legs—a common phenotype in domestic chickens. It was previously known that this is a Mendelian trait that maps to chromosome 24, with the yellow skin allele (W*Y) being recessive (Schmid et al., 2000). Eriksson et al. (2008) used a combination of identical-by-descent mapping and linkage analysis on a yellow skin times white skin backcross to refine linkage to a 23.8 kb region that contains only two genes: BX935617 and BCDO2. Resequencing of this region revealed a large 0.8% sequence divergence (over 200 nt) between the two haplotypes, making identification of causative mutation(s) difficult. Gene expression analysis (reverse transcription PCR) on white and yellow skin tissue showed only a weak expression of BX935617. However, reverse transcription PCR and pyrosequencing of BCDO2 from skin of six heterozygous birds showed moderate expression and, notably, that 90% of the transcripts were from the white skin (W*W) allele. This contrasts strongly with BCDO2 expression in the liver, which showed more equal representation of the two alleles. BCDO2 encodes an enzyme, beta-carotene dioxygenase-2 (or beta-carotene-9',10'-monooxygenase), that asymmetrically cleaves beta-carotene to create colourless apocarotenoids (Kiefer et al., 2001).

The authors therefore propose that the yellow skin phenotype is determined by one or more tissue-specific cis-acting regulatory mutations affecting BCDO2 expression. When the W*Y allele of BCDO2 is homozygous, its expression is low in skin tissue, the carotenoid remains intact and is incorporated into keratinocytes. In white-legged chickens, carotenoid deposition in the skin is prevented at the final hurdle by the expression of a cleaving enzyme in the skin tissue itself. An obvious test would be to measure the expression of BCDO2 in homozygous W*Y/W*Y birds—if the proposed mechanism is correct, then reduced expression of BCDO2 would be expected. It will also be necessary to demonstrate that BCDO2 is able to cleave lutein and/or zeaxanthin, which are the carotenoids deposited in chicken skin. A mutation affecting skin colour has previously been identified—the white-legged Wisconsin hypoalpha mutant (WHAM) chicken has a loss-of-function mutation in ABCA1 (Attie et al., 2002). In this case, white skin is one of a suite of traits affected, and the loss of carotenoid is probably related secondarily to a severe disruption in lipid transport, which prevents the delivery of carotenoids around the body. In contrast, the yellow skin phenotype affects only skin colouration, making this the first example of identification of the genetic basis of a specific carotenoid-based colour trait in any vertebrate.

The study also casts revealing light on the origin of the domestic chicken. Since Darwin (1868) proposed that domestic chickens were derived solely from red junglefowl (Gallus gallus) there has been much debate about a potential contribution from other junglefowl species in South Asia, and the geographical location(s) of domestication is still unresolved (Hutt, 1949, Liu et al., 2006). Eriksson et al. (2008) resequenced the 23.8 kb region from all four junglefowl species and found that W*Y haplotypes from yellow-skinned domestic chicken cluster into a single clade containing two wild species, the grey junglefowl, G. sonneratii, and the Ceylon junglefowl, G. lafayettii, which have reddish and yellow legs, respectively. In contrast, W*W haplotypes group within a clade containing sequences from the red junglefowl, which has white legs. This is in striking contrast to other loci such as mtDNA where all haplotypes from domestic chicken cluster with red junglefowl. Thus the W*W and W*Y alleles segregating in domestic chickens have independent origins from wild birds, and the most likely origin for the W*Y allele is through hybridization with the grey junglefowl during domestication. As the authors suggest, it would be interesting to perform a larger genomic study to see whether introgression from other species is a more widespread phenomenon. From an evolutionary perspective, it is notable that although the study initially focused on a mutation in domestic chickens, both the phenotypic and genetic variations underlying the trait are found among wild species, specifically the red junglefowl of South East Asia and the grey junglefowl of India; so this study is hugely relevant to the evolution of carotenoid-based colouration in nature.

Many showy carotenoid displays are used to attract mates or signal to members of the same sex, and there has been much debate as to how these displays are able to be honest indicators of quality. It is of considerable importance to know if carotenoid traits are genetically correlated with other traits that may confer a fitness advantage. It is therefore interesting that Eriksson et al. (2008) tested for association between yellow skin and a suite of 80 other traits (for example, growth, egg production, behaviour) in a quantitative trait loci analysis. However, no evidence of a genetic correlation was found—after correction for multiple tests, no traits were significantly associated with yellow skin genotype. Of course, this does not address whether there are correlations between carotenoid traits and other traits in wild populations, but it does show that carotenoid variation is not necessarily associated with strong pleiotropy.

The real surprise of the study is the nature of the probable mechanism uncovered. Although not emphasized by the authors, the results strongly suggest that the ancestral state in junglefowl is yellow skin. This follows as the white skin phenotype is due to a gain of function—an increase in expression of BCDO2 in the skin promoting carotenoid cleavage, and no other function for BCDO2 in the skin has been proposed. The carotenoid uptake through the gut, metabolism and storage in the liver and circulation in the blood appear to be unaffected—it is only the final deposition stage. This goes against the prevailing view that carotenoid-based traits in birds are generally derived. This study therefore leads to many novel avenues of research. Is this a mechanism for variation in carotenoid colouration among other species? Does this enzyme play a role within an individual to limit carotenoid deposition to certain areas of the body? These are questions that deserve extensive investigation. For carotenoid researchers, perhaps future emphasis should not only be placed on why some birds are colourful, but also on why others are not.

Darwin Was Wrong About Wild Origin Of The Chicken
March 4, 2008 · 3 Comments

Charles Darwin maintained that the domesticated chicken descended from the red jungle fowl, but new research from Uppsala University now shows that the wild origins of the chicken are more complicated than that.

Yellow-skinned chickens have a different version of a gene than their white-skinned cousins. Darwin believed that all chickens came from a wild species known as the red junglefowl. When the researchers looked for the yellow-skin gene in the red junglefowl, they only found the genetic variant that codes for white skin. More surprisingly, when they finally did find the yellow-skin version of the gene, it was present in a completely different wild species: the grey junglefowl.

“Our studies show that even though most of the genes in domesticated fowls come from the red jungle fowl, at least one other species must have contributed, specifically the grey jungle fowl,” says Jonas Eriksson, a doctoral student at Uppsala University.

It is most likely the case that the grey jungle fowl was crossed with an early form of the domesticated chicken. The genes for yellow skin are spread among billions of domesticated chickens around the world. Darwin’s studies of domesticated animals were of key importance to his theory of evolution, and he also explained the wild origins of domesticated animals.

“What’s ironic is that Darwin thought that more than one wild species had contributed to the development of the dog, but that the chicken came from only one wild species, the red jungle fowl. Now it turns out that it’s just the opposite way around,” says Greger Larson, a researcher at Uppsala University and Durham University in England.

The yellow leg color is a result of fodder: the more yellow carotenoids there are in the feed, the yellower the legs. The gene that these researchers have now identified codes for an enzyme that breaks down carotenoids and releases vitamin A. This gene is shut down in skin but fully active in other tissues in chickens with yellow legs. The consequence is that yellow carotenoids are stored in the skin in these chickens. This is called a regulatory mutation since the coding sequence of the gene is intact, but its regulation is modified.

“Our study is a clear example of the importance of regulatory mutations in the course of evolution. What we don’t know is why humans bred this characteristic. Maybe chickens with bright yellow legs were seen as being healthier or more fertile than other chickens, or were we simply charmed by their distinct appearance?” wonders Professor Leif Andersson, who directed the project.

The scientists believe that the same gene may well be of significance in explaining the pink color of the flamingo, the yellow leg color of many birds of prey, and the reddish meat of the salmon. These characteristics are all caused by carotenoids. The gene may also influence the skin color of humans to some extent.

Nice to hear from you, Kermit! Last spring I wrote an article for the Club newsletter about yellow skin, and have copied it below.

Personally, I believe that the unique-to-Araucanas blue eggshell gene would be more interesting to study than rumplessness, which has a long history in European chickens and may have been introduced to South America by Europeans. There has been some speculation about crosses with pheasants having introduced the blue eggshell gene, and the tools are available to check this out, if a scientist (Alice Storey?) had enough interest and resources.

Rosalyn

--------------------------------------------------------------------------------------------------------------------------------------

The red junglefowl has long been presumed to be the sole wild ancestor of domestic chickens, although there has been some controversy over the years. This is because several other closely related species of junglefowl exist in South Asia, namely the grey and Ceylon junglefowl, which can hybridize with domestic chickens although most of these hybrids are sterile. However, a number of recent scientific studies looking at this possibility have only found a red junglefowl parentage in domestic chickens. So although it is possible that grey and Ceylon junglefowl interbred with chickens in the distant past, there has been no evidence that any of their genes ended up in chickens. That is, no evidence until this scientific paper was published last month in the journal PLoS: “Identification of the Yellow Skin Gene Reveals a Hybrid Origin of the Domestic Chicken”, by Jonas Eriksson et al.

The close look at the gene for yellow skin was prompted by the observation that red junglefowl have white skin, whereas grey and Ceylon junglefowl have yellow skin. Araucanas have yellow skin, as do virtually all commercial broilers, because of the wide consumer preference for yellow skinned meat. Many European breeds have white skin, such as the Ameraucana, Old English Game and Polish.

It’s been long known that the gene for yellow skin is recessive to white skin, and that the intensity of the yellow skin is influenced by the amount of carotenoid pigments in the diet. The gene for white skin, called BCDO2, is an enzyme that cleaves colorful carotenoids to colorless apocarotenoids. Therefore, when it is active in the skin, the skin is white. Yellow skin results from a regulatory mutation in this gene so that the enzyme is not made in skin, although it is made in other parts of the body. The lack of this enzyme in the skin allows yellow carotenoid pigments to accumulate, resulting in yellow skin.

So how did the scientists trace the origin of the gene for yellow skin to the grey junglefowl? They did it by first comparing white skinned and yellow skinned chickens. If the trait for yellow skin had simply come from a mutation in the gene for white skin in chickens, then you would expect that the genes for white and yellow skin would be pretty much the same in their DNA sequences except for the mutation. However, this wasn’t the case, as the DNA sequences were quite different. This led the scientists to look at the DNA sequences for yellow skin in the grey junglefowl and Ceylon junglefowl. They discovered that the DNA sequence for yellow skin from the grey junglefowl was a very close match to the DNA sequence for yellow skin found in chickens. This led them to conclude that the gene for yellow skin in chickens came from the grey junglefowl. How long ago did this happen? Probably fairly early after chickens were domesticated, because yellow skin is found widely distributed around the world.

It seems like yellow skin is the only trait that was incorporated from grey junglefowl, at least from what is know at this point. How could this happen? Let’s assume that a grey junglefowl (yellow skin) and chicken (white skin) mated and produced some fertile offspring several thousand years ago. These offspring mated with each other, and a few hybrids with yellow skin began cropping up. The farmers liked yellow skin, and began selecting these hybrids to mate with their other chickens. If they did this for only 10 generations, less than 1% of the genes from the grey junglefowl would be left. Since many hundreds or even thousands of generations have passed, it isn’t too surprising that the gene for yellow skin is the only gene left, since this was the only trait of the grey jungle fowl being selected for by the farmers.

The grey jungle fowl (Gallus sonneratii) is a magnificent bird, as you can see from the cover picture. They are primarily found in southern India, in deciduous forest and at the edges of moist deciduous forests. They forage for insects and worms by scratching. The elongated neck feathers are dark and end in a small, hard, yellowish plate. They almost went extinct because these uniquely colored, waterproof, waxy hackle feathers were highly prized for fly tying, and hundreds of thousands of pelts were exported yearly to Europe in the early 20th century.

And where do blue eggs come into the story? It has long been speculated that blue egg color was introduced by crosses of chickens with pheasants. Even though most of these hybrids are sterile, it is thought that an occasional fertile hybrid might have occurred, and been selected for because of the unusual egg color, just like the grey junglefowl hybrids with yellow skin were selected. The scientific tools are available now to check this out, just like the gene for yellow skin, if only some scientist was interested in doing so.

The closest living relative of the genus Gallus is Pternistis, a group of closely related African Francolins. We can envision the common ancestor of the Junglefowl and African Francolins as a bird not unlike a female Ceylon or Green Junglefowl in size and morphology. Many of the Araucanian hens of South America and Easter Island, especially the Colloncas and Ona with their henny feathering and diminutive size, are in many ways a complete reversal or throw back to ancestral phenotype. This is also true of many dabbling ducks closely related to the mallard, which are endemic to oceanic islands

plesiomorphic Applied to a character state that is based on features shared by different groups of biological organisms and inherited from a common ancestor. The term is taken from the Greek plesios, ‘near’, and morphe, ‘form’, and means ‘old-featured’. The features to which it is applied were formerly called ‘primitive’. It is the opposite of apomorphic.

That's a wonderful article Rosalyn. Thank you for posting it. It asks a few questions that require some elucidation.
Ongoing research at Lund Uppsala, Kagoshima University and also within specialist groups working within the Chicken Genome Project have made some startling discoveries via utilization of Nuclear DNA, which maps the male DNA ancestry versus the mtDNA of the female ancestry.
Previous molecular work only studied the mtDNA and from that work along with RFLP types, it was established that single subspecies ( Burmese/Thailand) of the Red Junglefowl, Gallus gallus, suffices as the sole matriarchal ancestor of 99% of all known domestic breeds. The following photos are of the nominate mainland form of the Red Junglefowl:

These next photos are of the Indonesian Red Junglefowl Gallus bankiva. While it is listed as a subspecies of the nominate mainland ( Burmese) Red, it is genetically as distinct from that aforementioned form, as the the Coyote is distanced from the Grey Wolf. The Indonesian Red Junglefowl split from the Indian Red Junglefowl ( G. murghi) during the Pleistocene. The Burmese Red Junglefowl spit from the Indian Red JF ~ 78 Thousand years ago. At any rate here are some photos of the Indonesian Red Junglefowl Gallus bankiva:

Nevertheless, another subspecies of the Red Junglefowl, the Indonesian Red Junglefowl, Gallus bankiva,phenotypically very similar with the nominate form, was also shown ( RFLP studies) to be the matriarchal ancestor of a tiny number of archaic Indonesian/Oceania breeds. This is significant because the early Indonesian cultures domesticated their indigenous Red Junglefowl ~ 1500 years before the cultures of Thailand and Burma domesticated theirs. The first domesticated chicken breeds were fighting games. These were not the sadistic betting matches of the modern crowd, but rather, the ceremonial and spiritual foundations of a very ancient culture.
What is more, the Indonesian Red Junglefowl is genetically completely compatible with the Burmese Red Junglefowl. In other words, trade between the respective cultures resulted in the crossing of their separately derived stocks. Both male and female crosses between the Red Junglefowl subspecies were fully fertile. Indeed, hybrid vigour very likely resulted in Heterosis or "hybrid vigour":

Heterosis is a term used in genetics and selective breeding. The term heterosis, also known as hybrid vigour or outbreeding enhancement, describes the increased strength of different characteristics in hybrids; the possibility to obtain a genetically superior individual by combining the virtues of its parents.


Heterosis is the opposite of inbreeding depression, which occurs with increasing homozygosity. The term often causes controversy, particularly in terms of the selective breeding of domestic animals, because it is sometimes believed that all crossbred plants or animals are genetically superior to their parents; this is true only in certain circumstances : when a hybrid is seen to be superior to its parents, this is known as hybrid vigor. When the opposite happens, and a hybrid inherits traits from their parents that makes them unfit for survival, the result is referred to as outbreeding depression. Typical examples of this are crosses between wild and hatchery fish that have incompatible adaptations.

Two competing hypotheses, not necessarily mutually exclusive, have been developed to explain hybrid vigour:

* Dominance hypothesis. The dominance hypothesis attributes the superiority of hybrids to the suppression of undesirable recessive alleles from one parent by dominant alleles from the other. It attributes the poor performance of inbred strains to loss of genetic diversity, with the strains becoming purely homozygous at many loci.
* Overdominance hypothesis. Certain combinations of alleles that can be obtained by crossing two inbred strains are advantageous in the heterozygote. The overdominance hypothesis attributes to heterozygote advantage the survival of many alleles that are recessive and harmful in homozygotes. It attributes the poor performance of inbred strains to a high percentage of these harmful recessives.

Nearly all the field corn ( originally domesticated by aboriginal South and Central Americans) now grown in the United States and most other developed nations is hybrid corn. Modern corn hybrids substantially outyield conventional cultivars and respond better to fertilization.

Heterosis in maize was famously demonstrated in the early 20th century by George H. Shull and Edward M. East after hybrid corn was invented by Dr. William James Beal of Michigan State University based on work begun in 1879 at the urging of Charles Darwin. Dr. Beal's work led to the first published account of a field experiment demonstrating hybrid vigor in corn, by Eugene Davenport and Perry Holden, 1881. These various pioneers of botany and related fields showed that crosses of inbred lines made from a Southern dent and a Northern flint, respectively, showed substantial heterosis and outyielded conventional cultivars of that era. However, at that time such hybrids could not be economically made on a large scale for use by farmers. Donald F. Jones at the Connecticut Agricultural Experiment Station, New Haven invented the first practical method of producing a high-yielding hybrid maize in 1914-1917. Jones' method produced a double-cross hybrid, which requires two crossing steps working from four distinct original inbred lines. Later work by corn breeders produced inbred lines with sufficient vigor for practical production of a commercial hybrid in a single step, the single-cross hybrids. Single-cross hybrids are made from just two original parent inbreds. They are generally more vigorous and also more uniform than the earlier double-cross hybrids. The process of creating these hybrids often involves detasseling.

The concept of heterosis is also applied in the production of commercial livestock. In cattle, hybrids between Black Angus and Hereford produce a hybrid known as a “Black Baldy.” In swine, “blue butts” are produced by the cross of Hampshire and Yorkshire. Other more exotic hybrids such as “beefalo” are also used for specialty markets.

Within poultry, sex-linked genes have been used to create hybrids in which males and females can be sorted at one day old by color. Specific genes used for this are genes for barring and wing feather growth. Crosses of this sort create what are sold as Black Sex-links, Red Sex-links, and various other crosses that are known by trade names.

Commercial broilers are produced by crossing different strains of White Rocks and White Cornish, the Cornish providing a large frame and the Rocks providing the fast rate of gain. The hybrid vigor produced allows the production of uniform birds with a marketable carcass at 6-9 weeks of age.

Likewise, hybrids between different strains of White Leghorn are used to produce laying flocks that provide the majority white eggs for sale in the United States.

The Colloncas was intentionally bred to the Quetero in South America. The composite stock are the founders of the North American Colloncas de Artes or Tufted Rumpless Araucana ( though we should be certain that any number of other breeds were used as well).A different composite between Mapuche/Quechua, Quetero and Colloncas resulted in the Falklands Islands Hen which gave rise to the U.K. Araucanian hen and the Americauana. The original archaic breeds of the native peoples were highly inbred. South American Indians were master selective breeders. The number of cultivars of chiles, beans, corn, potatoes, cotton and sunflowers, the quinoa and camelides they generated is fairly astonishing. Backcrossing after outcrossing is the method they apparently utilized to the best efficiency.

We must remember that for early cultures working with stock that was only very early on its evolution from wild founders, it was very nearly impossible to distinguish one individual animal or flock from another. The stock would also produce a large percentage of individuals whose instincts obliged them to go feral at adult hood, especially during nesting. Trade between different cultures with their respective gene stock, descended of divergent wild progenitors, would theoretically result in the generation of readily discernible stock.In other words, a few chicks would hatch that exhibited features that made them stand out from the others. Thus, with each successive generation of selective breeding, the stock was sculpted into increasingly divergent sub races.
This was a two part process. After outcrossing between divergent stocks, for example between a bankovoid game male and a Vietnamese game hen ( again, the game breeds were early offshoots of the wild progenitors) subsequent close inbreeding of stock put these lineages through prerequisite genetic bottlenecks which resulted in a higher expression of certain mutations. The degradation of genes carried by the wild founders is necessary to produce a domestic breed. Extinction via domestication is how the captive populations of Golden Pheasant, Muscovy and Mandarin Ducks, Helmeted Guineafowl and Indian Peafowl to name a few-are becoming increasingly homogenized in the quest for desired mutations. The early indigenous peoples of Indonesia were basically carving whole loci of genes from the DNA strand by close inbreeding. This is how domesticated breeds were created.

Bottlenecks and Founder Effects

Genetic drift can cause big losses of genetic variation for small populations.

Population bottlenecks occur when a population’s size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population’s genetic variation by a lot, even if the bottleneck doesn’t last for very many generations. This is illustrated by the bags of marbles shown below, where, in generation 2, an unusually small draw creates a bottleneck.

Pré-Columbian (Araucana) New Finding - Page 1 Marbles4

Loss of genetic variation as a result of a population bottleneck

Reduced genetic variation means that the population may not be able to adapt to new selection pressures, such as climatic change or a shift in available resources, because the genetic variation that selection would act on may have already drifted out of the population.
l

An example of a bottleneck:
Northern elephant seals have reduced genetic variation probably because of a population bottleneck humans inflicted on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000—but their genes still carry the marks of this bottleneck: they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted.

Founder effects
A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have:

* reduced genetic variation from the original population.
* a non-random sample of the genes in the original population.


For example, the Afrikaner population of Dutch settlers in South Africa is descended mainly from a few colonists. Today, the Afrikaner population has an unusually high frequency of the gene that causes Huntington’s disease, because those original Dutch colonists just happened to carry that gene with unusually high frequency. This effect is easy to recognize in genetic diseases, but of course, the frequencies of all sorts of genes are affected by founder events.

Early mutations the ancient cultures may have been selecting for, may have been melanistic sports and/or leucistic sports. Close inbreeding was necessary to make these traits dominant in a population. For example, a single sire may have been the sole male founder of closely bred stock and for multiple generations. One generation of people would pass down their invaluable stock to the next. An Indonesian spice trader, originally from Java, might end up relocating his family in Bangkok Thailand, and with his grandfather's prize fighting game cock. The Indonesian spice trader's son is married to a local Thai village chief's daughter. The daughter's family presents the Indonesian family with a prized Thai game hen. That one Bankivoid rooster, bred to the mother or sister of a local Thai fighting champion, would theoretically be the founders of a new generation, and though new females may have been introduced on occasion, the patrilinear line remained intact for five or fifteen more human generations. In other words, the Indonesian family maintained their patrilinear line for as long as their family remained in that village in Thailand which may have been several human generations. What is more, this family may have even carried that stock- now admixtured- back to Indonesia- four of five hundred chicken generations later. Now their stock has the mtDNA signature of the Burmese Red JF but the Nuclear DNA of the Indonesian Red JF because no other males but sons of that one bankivoid founder sired chicks for all those generations. That is how unique strains were created which would eventually generate unique breeds.
It should be remembered that based upon genetic analysis, male chickens were transported much further and more often than female chickens. A prized champion game cock or long crower might be transported from Indonesia, to Thailand and then all the way to the Phillipines or Japan. In the case of the early migrants onto the archipelagos bridging Indonesia with Oceania, the Pacific and South America, the distances were even greater.

The genus Gallus is originated from Asia and comprises four species (Hutt, 1949): Gallus varius (Shaw.), Gallus sonneratii (Temminck), Gallus lafayettei (Lesson) and Gallus gallus (Linné). According to Darwin (1875), the domestic fowl originates from the species G. gallus (Gallus gallus domesticus), and molecular analyses of mitochondrial DNA have confirmed that G. gallus is the monophyletic origin of the domestic fowl (Fumihito et al., 1996; Fumihito et al., 1994).

Domestication of Gallus gallus fowls started in Taiwan and neighbor regions in Southeastern Asia (Wood-Gush, 1959; Zeuner, 1963; Fumihito et al., 1994, 1996), and it was brought to China in 6000 a.C. (West & Zhou, 1988). Evidences of hen domestication were found in 16 Neolithic archeological sites in Northeastern China, corroborating the above-mentioned findings. It is believed that domestication of fowls was related to religious aspects (Zeuner, 1963), and also to leisure (codkfighting) and adornment (use of feathers in clothes).

Studies performed by Komiyama et al. (2003) and Komiyama et al. (2004) have demonstrated the relationship between the origin of different native Japanese breeds and cultural traditions. The birds were brought to Japan through two different routes, Central China and Southeastern Asia, and originated the Shamo breed (Komiyama et al., 2003). This is a traditional breed of fighting roosters that was involved in the formation of many Japanese breeds. Besides, singing roosters are another cultural tradition in Japan, and the three Japanese breeds of singing roosters have also originated from Shamo (Komiyama et al., 2004), which evidences that our ancestors have first tried to domesticate the birds for cultural purposes before raising them as food sources.

To reiterate:
Early agricultural centres of South and Southeastern Asia were founded on what could be termed as fore bearers of the chicken industry. Whole villages/regions dedicated themselves to the selective breeding and refinement of the domestic fowl, included Western India, Sri Lanka, Bali, Java, Sumatra, Thailand, Cambodia Vietnam and Taiwan. The fighting game industries of Sri Lanka, Bali, Java and Sumatra preceded those of India, Cambodia, Vietnam and Taiwan by nearly two thousand years.

Pré-Columbian (Araucana) New Finding - Page 1 Lafayetti12
The Ceylon Junglefowl, G. lafayetti, ( this is a juvenile male) is genetically basal or ancestral to the Grey Junglefowl G. sonnerati. Nuclear DNA studies suggest that the Peacomb gene is one of the rare alleles unique to the Ceylon JF and domestic chickens with Ceylon JF sires/ genetic bottleneck in their ancestry

However, as Nuclear DNA studies got under way we learned a great deal more about the Patrilinear ( male) ancestors. We learned that while the female ancestors of most domestic chicken breeds was the nominate Red JF, and a few bankiva Red JF, most fighting Games had Bankivoid male ancestors.
What is also interesting and more pertinent to the Araucanian hen, the Bantam breeds were also in generation and only a few hundred years behind the Games.
As we have read in the recent papers regarding yellow skin pigment gene, it is not present in Gallus gallus nor in Gallus bankiva. It is however present in Ceylon and Grey Junglefowl. Sri Lanka ( once called Ceylon) was for several centuries, like Bali and Northern Western Sumatra, a veritable hub of a chicken breeding industry. Unique strains unique to each of these regions would generate the founder stock of the Bantams. These strains were founded by with females descended of Bankiva X Gallus founders. A significant percentage of the male founders of the original Bantams came from further afield.

. Etymologically, the name bantam is derived from the city of Bantam, once a major seaport, in Indonesia. European sailors restocking on live fowl for sea journeys found the small native breeds of chicken in Southeast Asia to be useful, and any such small poultry came to be known as a bantam.

Most large chicken breeds have a bantam counterpart, sometimes referred to as a miniature. Miniatures are usually one-fifth to one-quarter the size of the standard breed, but they are expected to exhibit all of the standard breed's characteristics. A true bantam has no large counterpart, and is naturally small.

Bantam (Indonesian: Banten) in Banten province near the western end of Java was a strategically important site and formerly a major trading city, with a secure harbor on the Sunda Strait through which all ocean-going traffic passed, at the mouth of Cibanten River that provided a navigable passage for light craft into the island's interior which itself provides a good access to the hinterland.

As a trading city Bantam received an early influx of Islamic influence in the early 16th century. Bantam was the seat of a powerful sultanate. Later, the Portuguese and Dutch fought for control of Bantam in the 17th century. The English, who started to sail to the East Indies from around 1600, established a permanent trading post in Bantam in 1603. The Dutch found that they could control Batavia more thoroughly than Bantam, which contributed to its decline. South-Bantam or Bantan-Kidoel or Lebak was also the place where the main character Max Havelaar in Multatuli's novel Max Havelaar acted as the assistant-resident.

Today, Bantam is a small local seaport, economically overpowered by the neighbouring port of Merak. In Bantam, the Chinese are an important component of the community.

According to Nuclear DNA data the origin of the peacomb and both rumplessness and squirrel tail ( think Serama/Belgium Quail Bantam) is the Ceylon Junglefowl. The Grey Junglefowl and the Ceylon JF are difficult to distinguish on a molecular basis but the Peacomb and abbreviated spine of the Ceylon JF are dominant traits in its hybrids. Compellingly, crosses between Ceylon JF and domestic chickens are almost invariably sterile. This is not the case when a Ceylon JF is bred to a Bankivoid hen. The early bankivoid derived game breeds were more genetically compatible with the Ceylon Junglefowl male. According to Ghigi, female Ceylon JF do not produce viable embryos with Red JF even bankiva. When Ceylon JF were bred to bankivoid hens in Ghigi's experiments, they produced only a few fertile males and no fertile females.This follows Haldane's Rule:

Citation :


Haldane's rule relating to hybrids of species and extended to speciation in evolutionary theory is easily stated:

When in the offspring of two different animal races one sex is absent, rare, or sterile, that sex is the heterozygous (heterogametic) sex.

It was originally formulated in 1922 by the British evolutionary biologist J. B. S. Haldane. It is sometimes referred to as Haldane's law.

In many organisms, such as mammals or Drosophila flies, males are the heterogametic sex, in that they have XY sex chromosomes, whereas females are homogametic, with XX chromosomes. However, in some other animals (i.e. birds, butterflies) and plants, the reverse is usually true. Haldane's rule has been shown in a number of different hybrid crosses where either the male or the female is the heterogametic sex.

The fact that hybrid sterility and inviability can evolve due to Haldane's rule in such a vast array of different organisms is quite striking. However, the actual explanation of this phenomenon is rather complicated. Many different hypotheses have been advanced to explain the genetic basis of Haldane's rule.

* The dominance hypothesis: Heterogametic hybrids are affected by all, recessive and dominant, X-linked genes involved in incompatibilities, while homogametic hybrids are only affected by the dominant ones.
* Faster male hypothesis: Male genes evolve faster due to sexual selection.
* Meiotic drive: In hybrid populations, selfish genetic elements inactivate sperm cells (i.e: A X-linked drive factor inactivates a Y-bearing sperm and vice versa).
* Faster X theory: X-linked have a larger effect in reproductive isolation.

The dominance hypothesis is the most widely accepted explanation of Haldane's rule. However, the individual hypotheses are not mutually exclusive and many causes might potentially act together and cause hybrid sterility and inviability in the heterogametic sex. The faster male hypothesis, for example, receives support from a study in Asian Elephants.

Haldane's rule has a correspondence with the observation that some negative recessive genes are sex-linked and express themselves more often in men than women, such as color blindness or haemophilia.
Hybrids between Grey JF and Domestic Chickens are partially fertile with gametic problems arising in the f2 generation of fertile progeny which in turn, result in a larger percentage of fertile males than females.

Ceylon JF male, note the elongated plumes of the crown behind the comb.
The Ceylon sired progeny were unusual looking birds, often lacking a tail or exhibiting an unusually curved spine resulting in the squirrel tail. Another unusual trait was the absence of or modification of the comb in roosters and the presence of breast feathers with the same hue and pattern as the hackle. The Ceylon Junglefowl also exhibits special sub auricle plumage and red or yellow legs. The Ceylon Junglefowl is the only species of Gallus with elongated crown feathers. These plumes are obscured by the presence of the curious comb of the adult male but are more obvious in juvenile males. More prominently crested domestic breeds probably were derived of slightly crested bantams that originated in Ceylon, Bali and Sumatra. These valued roosters were fine fighters but their lack of fecundity resulted in very few progeny. The very few that did end up hatching were much prized and these birds were even more unusual than their hybrid fathers, for these birds often exhibited unusual plumage pigmentation and/or morphology. Leucistic sports in Ceylon JF are not uncommon in wild populations. A wild leucistic Ceylon JF ( itself most probably the result of a much abbreviated gene pool) may very likely have been more often than not, the sire of many a lineage. A leucistic Ceylon Junglefowl is unusual in that it still retains iridescence throughout its white body.
According to Ghigi, frizzle plumage is not uncommon in f2 hybrids between Ceylon sired hybrids and bankivoid hens. Another common mutation in the subsequent generations is yellow legs and white or piebald plumage. Double spurs have also been noted in the occasional wild Ceylon JF.
As these hybrids tend to be smaller than their parental species in size with each generation, the generation of the rumpless Wallikiki or Basket Fowl was integral for the development of Bantams. This genetic stock- the males at any rate, became the founders of Silky, Sumatran, Minohiki and other important breeds.

The Grey Junglefowl and Indian Red Junglefowl were sires in more recent centuries of fighting games native to India. These strains gave rise to both the Mediterranean and European egg and meat breeds. Their maternal ancestors were the domesticated Gallus, but their sires were a combination of Grey,Indian Red and Burmese Red Junglefowl.

The Firefox or Ayam Katai a cross between Grey , Ceylon and Bankivoid fighting game first developed during ancient times and widely transported during subsequent centuries for game fighting and flytying, is according to Nuclear DNA studies, one of the male founders of such diverse breeds as the Marans, Barnsvelder, Fayoumi and Yokahoma, the Seabright Bantam and the Belgium Quail Bantam.

The Age of Discovery, also known as the Age of Exploration, was a period in human history starting in the 15th Century and continuing into the 17th Century, during which Europeans explored the world by ocean searching for trading partners and particular trade goods. The most desired trading goods were gold, silver and spices. Western Europeans used new sailing ship technologies, new maps, and advances in astronomy to seek a viable trade route to Asia for valuable spices which would be uncontested by Mediterranean powers. In terms of shipping advances, the most important developments were the creation of the carrack and caravel designs in Portugal. These vessels evolved from medieval European designs from the North Sea and both the Christian and Islamic Mediterranean. They were the first ships that could leave the relatively placid and calm Mediterranean, Baltic or North Sea and sail safely on the open Atlantic.
The original Marandaise ( ancestors of the Marans) and heirloom lineages of that breed, exhibit red legs which can only have been accrued from the Ceylon JF.

F1 Bekisars are either of maroon and burned orange colour morph or the birch blond and violet phenotype.
Pré-Columbian (Araucana) New Finding - Page 1 Ayambekkarasun
F2 Bekisars are called Bekiko and are generally the result of an F1 male being bred to an unrelated domestic game hen.
Pré-Columbian (Araucana) New Finding - Page 1 Bekisarsitjito
Selective breeding of fertile Bekiko results in the dramatic increase in tail length and saddle covert length due to its inheriting the the Green JF's Non-Moulting gene.

Meanwhile, quite separately, and independently, ~ four thousand years before present and consequently, long before Europeans had first traded with this part of Asia which didn't occur until the European age of discover,the peoples of Bali were developing a unique hybrid strain of their own. This hybrid included the same Bankivioid mothers as the aforementioned Ceylonese and Indian Bantam games, but rather than Ceylon, Grey or Indian Red, their sires were Green Junglefowl.These birds looked nothing like either parental species. There plumage was unusually coloured, often purple or maroon with a wide rounded collar at the base of the neck. Like the Green Jf, the hybrids carried a non-moulting gene and a consequence, their tails grew longer than the average game fowl. The Green JF has twice as many tail feathers as a Red JF and so the tails were also very generous in proportion to the size of the bird. Feathers were as valuable as money in those days, and what is more, each rooster had a unique voice. The same lack of fecundity were present in these hybrids as well. The odd fertile rooster ( 4 in 12) that proved fecund, would produce a brand new phenotype, never before seen in any chicken race. This is the birchen phenotype. So the f1 roosters were either very similar to the Green JF sires but with red and maroon/purple plumage, with normal length tails, or they were blonde and silver in colouration with long tails. Bred back to domestic hens- via backcrossing, the f1-f3 hybrid sires produced wholly black sports. It is the Green JF that carries the genes responsible for black pigmentation of tissues. Bred back to an unrelated domestic hen, the hybrid males produce birchen morphs with long tails and can be select bred for their voices and plumage simultaneously. It should be pointed out here that the majority of progeny produced were sterile mules. It took obsessive dedication by these early cultures to produce viable chicks. It must have been like searching for a pin in a haystack. Once they had backcrossed a few generations, all the males were fertile. Once they backcrossed these males a few more generations, fertile females would eventually be produced. THis is when the genetic outcrossing depression met its equilibrium. On an island, feral birds reached this equilibrium through much less extraordinary means. They self perpetuated by natural methods. The only birds capable of producing chicks did so and the most fit males bred more hens than those that were less fit. It probably took an island population of hybrids many decades or even a half century or more before they dissolved the outbreeding depression and produced fertile hens. Once that happened, they would have a population boom. The selective breeders were magnifying this selection via intentional backcrossing. That is, a domestic, fully fertile game hen mother to hybrid son for specific number of generations. Each successive generation would produce a male that was more desirable than the last. If the mother.grandmother/great-grandmother eventually dropped dead or ceased producing, they would procure a hen that was closely related to the matriarch- a full sister or daughter with her full brother- a domestic game cock. Within as few as ten generations of backcrossing, the Balinese and Kangean and Madera poultiers came to fully fertile hens.

Backcrossing fertile hybrid males back to their own domestic, bankivoid,game hen mothers, for a specific number of generations, increases size and surface area of bare facial skin while also increasing the percentage of individuals expressing hyper-melanism throughout the tissues.

The odd normal-coloured chick hatched from the same eggs as the hyper-melanistic Ayam Cemani are referred to as Ayam Pelung. It tends to be even more gargantuan than the Ayam Cemani.


Black melanistic birds were of particular value and hence the creation of the Ayam Cemani and Ayam Pelung its normally coloured sibling breed. Ayam cemani were used in the creation of Black Sumatrans which were a combination of naturally occuring black melanistic Bankiva junglefowl common in certain deeply forested regions of Sumatra and the Ceylon X Bankivoid Bantam stock we discussed earlier. Not incidentally, backcrossing of the aforementioned Bantam stock with Ceylon sire blood decreases the size with each generation. Backcrossing with Green sire blood increases the size with each generation.
This same root stock ( fertile Ayam Cemani females) was also used in the formation of the silky fowl. Getting back to the Balinese and Maduran selective breeding of Ayam bekisar and their domestic descendants- the birds were valued for their plumage and their song-the 'musical' long crows:

Gallus varius, known as Green Jungle Fowl is one of two endemic species of jungle fowls of Indonesia (Delacour, 1964). The other species is G. gallus bankiva which is believed to be the ancestor of the local domestic chicken. The Green Jungle Fowl has largely remained a wild species although it has been known for a long time as a pet animal for its beauty and unique call, especially among the people of Java, Madura ,and Bali. The cock of this species has been crossed with the domestic hen to produce a hybrid popularly known in the country as "Bekisar"
Bekisar contest is held every now and then in various parts of Java and perhaps also Bali. "Bekisar" has also been designated the mascot of the East Java Province. To promote the mascot, the local authority has made it compulsory for every hotel and restaurant in the province to display "Bekisar". Hence Bekisar industry has long been an important business in Indonesia .
Bekisar as a pet of social status has been documented as early as the 17 century at the time of the Mataram Kingdom. The hobby was limited to members of the Royal Family, rich people and high ranking officers (Sudrajad, 1990). The impact on the natural population was therefore not as serious. However since becoming the official mascot of the East Java Province the demand for Bekisar has been booming. Consequently hunting, especially for cocks, of the Green Jungle Fowl has increased, particularly in East Java (including Madura and the surrounding islands) and Bali. The local authority has encouraged people to keep Bekisar in their homes. For hotels in the province, it is compulsory to keep the hybrid. In addition concourses of Bekisar are held more frequently and more regularly in various places including Jakarta.
During the 16th and 17th Centuries, Ayam bekisars were carried to Japan where they became the male founders of the "singing" fowl including long crowers like the Koeyoshi, Tomaru and Totenko and the Long Tailed Onagadori.

To recap: Thousands of years ago early cultures traded primitive game fowl which were but a step away from being wild Red Junglefowl.
The earliest breeds were the progeny of hybrid sires between Indonesian Red and Burmese Red (vast majority); Ceylon and Indonesian Red (small percentage); Green and Indonesian Red (small percentage).
Selective breeding resulted in diminutive " Basket Fowl" or Wallikiki which were often rumpless or squirrel-tailed, with halting multi-syllabic crows; and Ayam bekisar which were generally long tailed and long crowed:

While the production of Ayam bekisar is a present issue in Indonesia, and one that played a prominent role in the creation of important ancient Japanese breeds of domestic fowl, it should be remembered that the first Green JF hybrids were produced nearly four thousand years ago. In the ancient days, when all the peoples living in Indonesia, were of the same ethnicity as the peoples of Melanesia, every outrigger canoe and fishing vessel had at least one of these Ayam bekisars on board. These communication devices/mascots/spiritual totem animals played an integral role in the culture of the first sea -faring peoples to leave Indonesia for Oceania, the Pacific and beyond.

One of the first major island cultures was that of the Marquesas. Peoples originally from Indonesia arrived and they brought with them, both Basket Fowls and Ayam Bekisars as well as plenty of Bankivoid games.

The Marquesas Islands are the island group farthest from any continent in the world, lying between 900 and 1,200 km (550 and 725 miles) south of the equator and 1,371 km (852 miles) northeast of Tahiti. They fall naturally into two geographical divisions: the northern group, consisting of Eïao, Hatutu (Hatutaa), Motu One, and the islands centered around the large island of Nuku Hiva: Motu Iti (Hatu Iti), Ua Pu, Motu `Oa and Ua Huka, and the southern group of Fatu Uku, Tahuata, Moho Tani (Motane), Terihi, Fatu Hiva and Motu Nao (Thomasset Rock), clustered around the main island of Hiva `Oa.

With a combined land area of 1,049 km² (405 sq. miles), the Marquesas are among the largest island groups of French Polynesia, Nuku Hiva being the second largest island in the entire territory, after Tahiti. With the exception of Motu One, all the islands of the Marquesas are of volcanic origin.

In contrast to the common perception of lush tropical vegetation that goes culturally hand-in-hand with the appellation "Polynesia", the Marquesas are remarkably dry islands. Although the islands lie within the tropics, they are the first major break in the prevailing easterly winds spawned from the extraordinarily dry (from an atmospheric perspective) Humboldt Current. Because of this, the islands are subject to frequent drought conditions, and only those which reach highest into the clouds (generally, above about 750 m/2,500 ft above sea level) have reliable precipitation. This has led to historical fluctuations in water supply, which have played a crucial rôle in the sustainability of human populations in certain sections of the various islands throughout the archipelago. This is especially evident in the low historical population of Ua Huka (maximum elevation 857 m/2,812 ft.) and the intermittent inhabitability of Eiao (maximum elevation 576 m/1,890 ft.).

Anaho Bay on the northwest coast of Nuku Hiva Island, Marquesas is a deep well-protected bay that is distinguished by its sizeable coral reef. A small number of test excavations were carried out at two localities. We identified an extensive buried cultural layer along the northern shore at Teavau'ua (AHO-1), dated to ca. the mid-15th century AD. Activities here included production of pearlshell fishhooks and basalt adzes, as well as more generalised domestic functions. We also identified short-term occupations dating to post-1650, and possibly earlier, at the more southern locality of Teonepoto (AHO-2).



These birds, which we must remember were early on in the development of domestication and included some percentage of hybrid male founders, went feral on the Marquesas islands and thanks to different founder make up on each respective isle, each gave birth to a unique morphotype- a species if you will, endemic to each atoll. The presence of Green JF ancestry is likely to have given some lineages a selective advantage in that their wild Gallus varius forebearers are adept island hoppers, with a natural range extending from Java to Flores and all the tiny desert islands in between. The Green Junglefowl is a mangrove and shoreline specialist. It apparently, requires less fresh water than the Red JF and is able to digest and even thrive on shore detritus and sea life that Red JF and its domestic descendants would be incapable of. Green Junglefowl are also capable fliers, able to sustain themselves in the air over surprisingly vast distances over the open sea. Hybrid descendants of Green JF, were thus capable of localizing themselves in a manner that typical Red JF and domestic fowl fail in.
As some of the more populated islands had larger percentages of fowl with more diverse genetic origins, namely, those with Ceylon,Green, Indonesian and Burmese Red JF progenitors, whilst others were only frequented by populations of birds with Green and Indonesian Red JF founders, early European Naturalists believed that each island form was its own unique species:

The Araucanian hen ( and its fore bearers ) are unique in all the poultry world for the presence of two traits, unknown anywhere in Asia or Europe before their introduction to the West during the 19th century. The earrings or tufts of the Quetero, Colloncas de Artes; North American Araucana and European Araucana all have a common origin as too, does the tinted blue egg. I will cover the origins of the blue egg in a subsequent post. This post will deal specifically with the earrings or tufts and perhaps alarmingly for some of the standards crowd, the sub-auricle ruff and muff of the Mapuche/Quechua and U.K. Araucana as well as the Americauna;Japan's Koeyoshi and Siberia's Russian Orloff.
Please note the region imm adjacent and below the ear; and throat in these two species of Junglefowl:

Pré-Columbian (Araucana) New Finding - Page 1 Kur-lafayetti01_1774-1
G. lafayetti: note specialized, light reflective plumes covering the throat. These extend under the hackles to a region immediately below the ear.
Pré-Columbian (Araucana) New Finding - Page 1 Varius_overgrown_bill[/
G. varius: note the same region as previous species. Its more subtle because the neck hackles blend in texture and pattern. Also, note skin tag behind ear.

Pré-Columbian (Araucana) New Finding - Page 1 Stavenn_Gallus_varius_00
G. varius
What is less obvious in the photos of the males, is just how densely feathered the faces of their females are.

Pré-Columbian (Araucana) New Finding - Page 1 Variusmale
A male in non-breeding condition will exhibit a prominent sub-auricle patch, which extends to a region below the eye, and continues at the throat.

Pré-Columbian (Araucana) New Finding - Page 1 Galluslafayetti7
Pré-Columbian (Araucana) New Finding - Page 1 Variusfacedark
While G. lafayetti exhibits elongated feather bristles which cover its ear openings, G. varius exhibits a special fold of skin which serve to waterproof its ear openings. These special adaptive features are utilized while the bird is sleeping, often with its bill tucked between wing and back. The large impressive combs of the Junglefowl, together with Gular Lappet/Wattles are utilized in communication across distance ( the colours of the bare facial skin change dramatically depending on the situation). They also are helpful in keeping the birds cool as they forage under an intense sun. South American breeds with feathered gular lappet have retained the plumage that normally only covers the throats of females and juveniles. What is more, and this speaks to the rapidity of mutation in genetically isolated populations, the feathers have multiplied and become insulative features against the cold.

Thousands of years ago, early cultures carried semi-domestic fowl of mixed ancestry to islands, hundreds and even thousands of miles away from South East Asia.
These fowl were often intentionally left on islands like Ponape and Pitcairn where they would provide food for subsequent voyagers. As we've discussed the founder effect and genetic bottlenecks, and the term of plesiomorphic ( throwback primitive traits generated through genetic recombination ( hybridization and backcrossing). Some of these island populations were transformed in time by natural selection and genetic drift. These populations ended up producing a high number of Henny feathered morphs.
Pré-Columbian (Araucana) New Finding - Page 1 Henny
Pré-Columbian (Araucana) New Finding - Page 1 Yellowneckedspurfowl
Henny feathered individuals are analagous with the monomorphic African Francolins, the sexes of which are entirely similar. Henny feathering and rumplessness are particularly common in experimental backcrosses between Ceylon and Grey Junglefowl performed by Ghigi. Fayoumi, Lakenvelders and Campine are derived from Ayam katai sires early on in the development of domestic fowl carried westwards by traders of the Axum nobility. Limited sires in this first population of domestic chickens to reach Egypt and Jerusalem resulted in the characteristic fixed Henny traits of these ancient breeds.

Pré-Columbian (Araucana) New Finding - Page 1 CookIslandsRed2
These Cook Island Red junglefowl are genetically compelling because they share paternal ancestry with the Marquesas/Tongan/Samoan fowl, which are of mixed ancestry. However, unlike those populations, new imports of Red Junglefowl were brought by subsequent migrants to the Cook Islands. Nevertheless, the genetic bottleneck experienced by the first population of Cook Island Red JF is discernible in the genetics of the tested birds,because the original genetic founders of the present day Cook Island Junglefowl were of mixed ancestry. Where the Henny feathering is not present on the island, the female junglefowl belie their ancestry with masculine retrices similar to those of Henny feathered males. This is believed to be a trait accrued from Green Junglefowl ancestry and subsequent genetic inbreeding.
Pré-Columbian (Araucana) New Finding - Page 1 HawaiinRedJF
Hawaiian Red JF also exhibit greatly elongated tails, and blonde hackles in many males, another trait accrued from G. Varius. hybrid founders.


Moving back to the very remote island populations where Southern Mongoloid ancestors of the Polynesians never reached or introduced the Gallus gallus , mainlanf Red Jf: Thousands of years of isolation on remote islands with no new incoming genes resulted in what could be termed as the development of novel species.
By the time the earliest explorers of South America reached and named the Strait of Magellan, they reported eating blue eggs of a local breed of domestic hen.
Illustrations provided by these explorers are informative.
Pré-Columbian (Araucana) New Finding - Page 1 Quail20quechua
The South American birds exhibited traits unknown to Europe, Asia and Arabia, namely the blue egg but also the near-complete feathering of the facial region.
Another trait more discernible in some populations than others, is the tendency for a single throat lappet and this is heavily feathered in some subraces, especially those of the cold coastal regions of South America.

Pré-Columbian (Araucana) New Finding - Page 1 KoeyoshiPr
The Japanese Koeyoshi long-crower also has the male DNA of G. varius. Note how the single gullar lappet is feathered in the female.

Pré-Columbian (Araucana) New Finding - Page 1 Black-redArauHHeadUK
Pré-Columbian (Araucana) New Finding - Page 1 250px-whitetufts
It took a slightly different gene founder composite and much more isolation and time for the full feathering of the throat and ear to produce prominent tufts. The founders of that stock arrived in South America after hundreds or even thousands of years of isolation on Rapa Nui.
We continue to select for these traits even today. Our birds are for all intensive purposes Gallus domesticus, but genetic evidence tells us we shouldn't marginalize the historical legacy of the first oceanic seafarers that carried the birds across so much distance.
Because so few South American birds were ever imported into the United States, the majority of their genes are shared with those of other common domestic birds which originated in Europe. Their few novel genes, the ones we continue to select for, were accrued from Gallus g. inarius- the earringed fowl of South America.
While we don't accept muffs or beards in American Araucana, they are desireable traits in Europe. This is because Europeans brought their birds directly from the Falklands where all the native fowl are prominently muffed/bearded.

The Falkland Islands have had a complex history since their discovery, with France, Britain, Spain, and Argentina all claiming possession, and establishing as well as abandoning settlements on the islands. The Falklands Crisis of 1770 was nearly the cause of a war between a Franco-Spanish Alliance and Britain. The Spanish government's claim was continued by Argentina after the latter's independence in 1816 and the independence war in 1817. The United Kingdom returned to the islands in 1833 following the destruction of the Argentine settlement at Puerto Luis by the American sloop USS Lexington (28 December 1831). Argentina has continued to claim sovereignty over the islands, and the dispute was used by the military junta as a pretext to invade and briefly occupy the islands before being defeated in the two-month-long Falklands War in 1982 by a United Kingdom task force which returned the islands to British control.

The first European explorer to sight the islands is widely thought to be Sebald de Weert, a Dutch sailor, in 1600. Although several British and Spanish historians maintain their own explorers discovered the islands earlier, some older maps, particularly Dutch ones, used the name "Sebald Islands", after de Weert.

In January 1690, English sailor John Strong, captain of the Welfare, was heading for Puerto Deseado (in Argentina); but driven off course by contrary winds, he reached the Sebald Islands instead and landed at Bold Cove. He sailed between the two principal islands and called the passage "Falkland Channel" (now Falkland Sound), after Anthony Cary, 5th Viscount Falkland (1659–1694), who as Commissioner of the Admiralty had financed the expedition, later becoming First Lord of the Admiralty. From this body of water the island group later took its collective English name.

With every abandoned settlement, be that French, British, Spanish, or Argentinian, a few South American fowl that had gone feral remained. Native foxes eliminated the heavily domesticated European chickens if any remained after a settlement packed up and left. We can't be sure that the Mapuche Indian's fowl were not intentionally interbred with domesticated fowl imported by European settlers, indeed we would expect ,that in fact, the native fowl did interbreed with European stock and various forms of selection- be that harsh climate, starvation or predation- would nevertheless follow. By the time the Falklands Islands were a stable settlement from which the British docked and exported South American resources from, the local population of feral fowl were once again, a unique group created by founder effect and genetic bottlenecks.
Pré-Columbian (Araucana) New Finding - Page 1 Mapuche1
Mapuche fowl from coastal Argentinian highlands.
The domestic fowl maintained to this day in the Falklands are descended of stock brought over by Argentinians who procured them from Mapuche and Quechua speaking Indian tribes. Whereas the Western Andean Colloncas and Quetero do not exhibit muffs or beards and their faces show only a very small percentage of bare skin, the Coastal Mapuche strains are almost always muffed/bearded.
This means that the traits for muffs and beards were localized to the cold and windy coastal regions and were either lost in high altitude Andean populations, or they were never present in such a developed form.
This Quetero hen photographed in a remote village of Peru by Archeology magazine has no ear tufts nor muff/beard but note the bright willow legs and prominent sub-auricle patch ( region densely feathered in velvet-like down that extends from the ear to below the eye and covers the throat.

Pré-Columbian (Araucana) New Finding - Page 1 South_American_Quetero_hen
Peruvian Quetero males tend to have prominent tufts and females only small sprigs. This isn't a rule and I've seen hens with pendulous earrings as well as plenty of feathered but tuftless hens. The Colloncas of Chile and Peru generally have neither ear tufts or muffs/beards but down in the coastal regions of Bolivia and Chile, the Colloncas will often have both muffs and tufts, or as in the case of these specimens photographed by National Geographic, genetic infusion of European derived chickens have resulted in single combed birds with prominent bare facial skin- also with prominent sub-auricle patch:
Pré-Columbian (Araucana) New Finding - Page 1 1_21_070604_collonca_chicken
This specimen photographed in the highlands of Chile exhibits a slight crest, another trait one sees in some rare South American breeds:
Pré-Columbian (Araucana) New Finding - Page 1 ChileanAraucanianrooster
There is one rare race of chickens native to Tierra Del Fuego carried about by the Ona and Huapi Indians which is not only rumpless, but Henny feathered, muffed/bearded with a slight crest. This morph has been reconstituted in the U.K. This is probably the closest approximation of what the majority of the basket fowl-derived Rapa Nui looked like, after centuries of close inbreeding and selection-in other words, the Huapi-Ona is probably what the ancestors of the Colloncas and Quetro most closely resembled- henny feathered, quail bantams with slight crests, fully feathered faces with insulation forming throat and ear feathering- with either a squirrel tail or no tail at all.

Pré-Columbian (Araucana) New Finding - Page 1 Colloncaseggs
Rosalyn mentioned a common question in her article regarding the origin of the tinted egg gene.
Many people have wondered if some pheasant may have been crossed to the domestic chicken to produce this trait.
Molecular data has shown us that Junglefowl are not pheasants but rather, members of their own subfamily which includes, Francolins, Bamboo Partridge and Coturnix Quail. None of these birds lay blue or green tinted eggs. Junglefowl and their allies are so distantly related to pheasants, their hybrid progeny are invariably sterile. Neither male nor female hybrids between pheasants and junglefowl can reproduce. Most birds are of dubious sex, the majority of which are females with masculine plumage. So where did the tinted egg come from?
Pré-Columbian (Araucana) New Finding - Page 1 Galluseggs-1
Of all the junglefowl species all but one lay brown or speckled eggs. The Red JF lay beige or buff brown eggs pigmented by oorhodeine,. The Grey JF lays buff speckled eggs ( oorhodeine,)and the Ceylon lays buff speckled eggs with variable pigment called lichenoxanthine,producing splotches or thoroughly covering the egg in some cases.
Pré-Columbian (Araucana) New Finding - Page 1 Sri_lanka_junglefowl_eggs_8761_ps
These pigments are produced in the haemoglobin by the chemicals uroporphyrin and coproporphyrin.
Citation :

In the matter of coloration the eggs of birds present a remarkable range. The pigments to which this coloration is due have been shown, by means of their absorption spectra (Sorby, Proc. Zool. Soc., 1875), to be seven in number. The first of these, oorhodeine, is brown-red in tone, and rarely absent: the second and third, oocyanin, and banded oocyanin, are of a beautiful blue, and though differing spectroscopically give rise to the same product when oxidized: the fourth and fifth are yellow, and rufous ooxanthine, the former combining with oocyanin gives rise to the wonderful malachite green of the emu's egg, while the latter occurs only in the eggs of tinamous: the sixth is lichenoxanthine, a pigment not yet thoroughly known but present in the shells of all eggs having a peculiar brick-red colour. Still less is known of the seventh pigment which is, as yet, nameless. It is a substance giving a banded absorption spectrum, and which, mixed with other pigments, imparts an abnormally browner tint. The origin of these pigments is yet uncertain, but it is probable that they are derived from the haemoglobin or red colouring matter of the blood. This being so, then the pigments of the egg-shell differ entirely in their nature from those which colour the yolk or the feathers.
The coloration of the egg bears no sort of relation to the coloration of the bird which lays it; but it bears on the other hand a more or less direct relation to the nature of the cance environment during incubation.

White eggs may generally be regarded as representing the primitive type of egg, since they agree in this particular with the eggs of reptiles. And it will generally be found that eggs of this hue are deposited in holes or in domed nests. So long indeed as nesting-places of this kind are used will the eggs be white. And this because coloured eggs would be invisible in dimly lighted chambers of this description, and therefore constantly exposed to the risk of being broken by the sitting bird, or rolling out of reach where the chamber was large enough to admit of this, whereas white eggs are visible so long as they can be reached by the faintest rays of light. Pigeons invariably lay white eggs; and while some deposit them in holes others build an open nest, a mere platform of sticks. These exceptions to the rule show that the depredations of egg-eating animals are sufficiently guarded against by the overhanging foliage, as well as by the great distance from the ground at which the nest is built. Birds which have reverted to the more ancient custom of nesting in holes after having developed pigmented eggs, have adopted the device of covering the shell with a layer of chalky matter (e.g. puffins), or, to put the case more correctly, they have been enabled to maintain survival after their return to the more ancient mode of nidification, because this reversion was accompanied by the tendency to cover the pigmented surface of the shell with this light-reflecting chalky incrustation.

Eggs which are deposited on the bare ground, or in other exposed situations, are usually protectively coloured: that is to say, the hue of the shell more or less completely harmonizes with the ground on which the egg is placed. The eggs of the plover tribe afford the most striking examples of this fact.

But the majority of birds deposit their eggs in a more or less elaborately constructed nest, and in such cases the egg, so far from being protectively coloured, often displays tints that would appear calculated rather to attract the attention of egg-stealing animals; bright blue or blue spotted with black being commonly met with. It may be, however, that coloration of this kind is less conspicuous than is generally supposed, but in any case the safety of the egg depends not so much on its coloration as on the character of the nest, which, where protective devices are necessary, must harmonize sufficiently with its surroundings to escape observation from prowling egg-stealers of all kinds.

Pré-Columbian (Araucana) New Finding - Page 1 VariusKomodo
Conversely, the Green Junglefowl, which subsists on invertebrates it catches at low tide in littoral pools, and on detritus along the shores, lays a dingy yellowish egg which chemical analysis has revealed to be pigmented through the shell with oocyanin and coated with a film containing lichenoxanthine.
Green Junglefowl on the island of Komodo produce greyish tinged eggs, whilst members of the same species on rocky atolls off the coast of Flores produce greenish and yellow tinged eggs. This phenomenon has been linked with the ingestion of chitin and sea life, which oblige the birds to remove potentially hazardous levels of certain natural chemicals through their bile. Oocyanin, the pigment responsible for blue shelled eggs, is produced in the bile.
More compelling is the issue of nest predation. Green Junglefowl have to deal with Monitor Lizards and Komodo Dragons, neither species use sight to locate their opportunist's banquets. The males offer their hot faces to the smaller monitor lizards in a manner essentially similar to the behavior we appreciate in fighting cocks- two roosters extend their necks and erect their hackles to their greatest expanse. When a Green Jf rooster faces down a monitor lizard it intends for the lizard to lock down on its gular lappet. This enables the nest guardian to dig his metatarsal spurs into the vulnerable belly of the would be predator.
On islands where monitor lizards are not present and humans have introduced fowl of mixed ancestry, especially those with Green sires, a great many hens would have produced non-viable eggs. The hens that did produce viable eggs were living on islands and atolls where seabirds frequently scavenge and steal eggs.
Eggs that match the substrate are less likely to get eaten by aerial predators than those that don't. Eggs that match the glare off the surrounding ocean go one step further. Rapa Nui fowl tend to produce stone hued eggs. These are greyish with some being a bit more greenish than others.
South American breeds produce a more refined hue and this may have something to do with the high amount of copper in the soil of Chile and Peru.
Perhaps the first chickens to reach the shores of South America were genetically inbred and those that survived developed an immunity to copper poisoning by expunging ingested copper through the bile. As one of the most important staples in South American Indian food is Quinoa, which is very rich in copper, perhaps the Colloncas and Quetero populations became blue egg producers because of the copper content in their diet which thanks to severe genetic bottlenecks and their mixed ancestry resulted in a novel mutation unique to South America.
All the same, many Quetero produce very ordinary coloured eggs like this nest photographed in Lima Peru:
Pré-Columbian (Araucana) New Finding - Page 1 Quetroheuvos
They were described as a Quechua word meaning " Pink" to the photographer who also claimed they were quite lovely shade of pink in person.

Ok- I've gone on and on here about Junglefowl Hybrids in the prehistory of domestic breeds.
Let me make a few things abundantly clear, so that nothing I've written here is misunderstood by people who tend to approach research on speed read rather than investigative exploration mode.

1. Wild and Captive populations of Junglefowl species are in danger of permanent extinction.

2. Common diseases of domesticated poultry flocks and is the source of the first greatest threat. Hybridization with domestic fowl is the second
3. I am in no way suggesting that any responsible or ethical poultier cross their domestic stock with wild junglefowl. Several Japanese and European researchers have conducted exhaustive cross-breeding experiments and learned that: Genetic outbreeding depression follows hybridization. This means that it takes many generations to return to a genetic equilibrium after hybridizing. Most embryos die in the shell. Each successive generation will produce new deleterious mutations which have adverse effect on productivity and/or encumber the expression of desirable traits. There have been cases where highly inbred strains of South American and Rapa Nui fowl have been outcrossed to both G. bankiva and G. varius. These outcrosses required dozens of generations of backcrossing to recover the original breed type.
4. Recent genetic research has revealed that Grey and Red Indian Junglefowl males are the sires of the vast majority of European domestic stock. Other research has revealed that Green, Ceylon and Indonesian Red Junglefowl males are the sires of the original Oceanic stock. It took the ancestors of the Polynesians, thousands of years to migrate from Indonesia and Taiwan respectively, to Melanesia, to Oceania and finally the Pacific and the western of the South American continent. Their breeds are even further along than those more familiar breeds of Europe. They should be respected as cultural heritage breeds. Selectively bred stocks, whatever their forms are genetic banks with whatever tiny alleles were accrued from their South American/Oceania ancestors and should be considered heirlooms. All breeds of cultural heritage breeds should be conserved with singular dedication.

5. The first ancestors of the Polynesian peoples were from Indonesia and were the same ethnicity as modern day Melanesians . They carried G. g. bankiva derived Bankivoid game fowl, bekisar X bankivoid hybrids and katai basket fowl bantams ( with Ceylon X bankivoid ancestry) with them.
6. Green and Ceylon Jf are more genetically compatible with Gallus bankiva Bankivoid derived game hens than with Gallus gallus derived game hens.

7. The second wave of ancestral Polynesians came from Taiwan/ Vietnam and were ethnically Southern Mongoloids, which displaced the aboriginal Melanesians throughout South East Asia ~three thousand years ago. The Taiwanese were similar to the ancient Vietnamese and Burmese peoples, in that they were slight admixtures with Melanesian. They carried Gallus g. philippensis and Gallus g. spadiceus with them. Micronesia became the first centre of their Oceanic dispersal after Taiwan.


8. Melanesian inhabited Island colonies experienced successive waves of territory seeking Southern Mongoloids. This began in Indonesia and continued to advance (as the populations of Southern Mongoloids burgeoned and the those of the Melanesians were fragmented and displaced) on every new island territory that the Melanesians managed to reach. When the Southern Mongoloids encountered the Melanesians, ethnocide was often the prescription. The same happened to Southern Mongoloid inhabited islands at the hands of territory seeking Melanesians. Men were killed; women and children enslaved. This ethnic war went back and forth for centuries. Each successive generation that passed, was made up of higher and higher percentages of people of mixed ethnicity. Soon, many islands were populated by a new ethnic majority that was neither solely Melanesian nor Southern Mongolian. The new ethnic majority were the first Polynesians .

The Lau girl seen here is from Malaita, the largest of the Solomon Islands. A new genetic study has found that Melanesians such as the Solomon Islanders are remarkably diverse because of thousands of years of relative isolation.
The study also found that the ancestors of modern-day Polynesians and Micronesians were most likely East Asians who island-hopped quickly through Melanesia.

9.Feral island populations descended of each original culture's respective game fowl admixture, experienced intense natural selection pressures and a non-random assortment of founders on remote islands prone to destructive typhoons, intermittent droughts, and a long list of predators including humans, feral pigs, feral dogs, and the nest predating monitor lizards, pythons and seabirds. As each feral colony of game fowl were of mixed ancestry, the reversion to wild type occurred straight away, and took the evolutionary/ecological paths of the male founders whose wild ancestry was better adapted to survive in the new habitats . Ceylon and Green Jf sired populations tended to thrive better than purely Red JF, especially on islands with limited fresh water and in regions frequently devastated by typhoons.

Both of these species can subsist largely on crustaceans including land crab carcasses and other detritus that Red JF cannot metabolize as efficiently. Red JF fared better on islands where new Red JF were introduced every few hundred years, by new human immigrants, or through trade with outsiders. Red JF traits are dominant on the Micronesian islands where Southern Mongolians managed to take possession early on.

10. The genetic outbreeding depression of more isolated island populations varied from island to island and depended largely on the number of fertile female founders and the percentage of hybrid male founders. Severe genetic bottlenecks were necessary before genetic equilibrium was reached and fertile females were produced, followed by population booms of genetically homogeneous individuals. This process required countless generations to produce the founders of the stock that the ancestors of the first Polynesians carried across the oceans.

11. Violaceous Junglefowl ( G. varius X bankivoid) and Marquesas Junglefowl ( G. varius X bankivoid X G. lafayetti X G. bankiva ) were carried by Melanesians
to all the major islands of Melanesia, Oceania and the Southern Pacific including Rapa and Rapa Nui ( Easter Island). These birds would remain on Easter Island for centuries before their eventual introduction to the Western Coast of South America.

12. At various points in history, prior to the arrival of Europeans, Chinese Jade Merchants reached the Western coasts of Mexico and Central America several times. They brought the ancestor of the Chihuahua ( Chinese Hairless Dog) and Black-Boned Chickens which after crossing with domestic fowl already in the possession of aboriginal South Americans would become the ancestors of the Black-Boned Huastec fowl:

Ok- so, my intention was to describe to the Araucana Club of American forum readers the complexities laden in the issue of trans-Pacific ocean voyages by "Polynesian" cultures. The very first waves of people to arrive on these islands were from Indonesia but are largely extinct in Indonesia today. Indeed, these people lived throught Southern Asia until about three thousand years ago when a different ethnicity outcompeted the original inhabitants and forced them to migrate further and further out into the ocean. Those early Indonesians were the ancestors of the present day Melanesians. The Southern Mongoloids - they came ~ fifteen hundred years later and they managed to claim some archipelagos to the exclusion of the Melanesians. The Melanesians carried chickens descended of a different female ancestor than the Southern Mongoloids. What is more, the Melanesians carried special ceremonial roosters aboard their sea-faring vessels and these were four or five in number. That is, each rooster, depending on its genetic ancestry, was considered its own evolutionary novelty- with its own special function. So each boat carried chickens and these all shared a common female ancestor but up to four different male founders. The Melanesians reached some very remote islands like Tonga and Samoa, Ponape, Fiji, New Caledonia and the Marquesas with these special ceremonial fowl.

A thousand or so years went by and suddenly the islands were under attack by their ancient foes, the Southern Mongoloids who carried their own respective ceremonial fowl which did not share the same genetic ancestry as that of the Melanesians' ceremonial fowl.

Another thousand years go by and typhoons and wars have left many an island nearly uninhabited and many thriving flocks of feral fowl and pigs have taken up the ecological niche they would have held in their native homes. As the Melanesians were genetically swamped by the Southern Mongoloids, so too were their domestic fowl and pigs. The only islands that would retain the original stock in its Violaceous or Marquesas form would be on very remote and isolated islands or islands protected by surrounding, Melanesian territories.

Ponape, Rapa and Rapa Nui - also known as Easter Island were places where Melanesians held on for centuries before Polynesians arrived.
The genetic outbreeding depression of island hybrid founders, followed by genetic inbreeding within a closed gene pool, resulted in the emergence of unique mutations- that made the Ponape and Rapa Nui fowl specially adapted for life on these desolate islands.
One of the mutations was the enhancement of the tinted egg gene accrued from their ancient Green Jf ancestors. Another- and we must remember that these birds were the only source of food industry on the island for centuries- trait to become dominate in the population was the complete feathering of the face, the diminishment of the bare facial skin and the enhancement of the ear covert plumage.

At some point in history, an entire clan of people from Rapa Nui must have migrated off of Rapa Nui, possibly to avoid being eaten by a newly arrived wave of immigrants- took to the sea with their chickens of various shapes and sizes and finally washed ashore on the coast of Western South America. These founding fowl became the progenitors of the Araucanian hen.

I realize I'm repeating myself here but it is integral that everyone gain a comprehension of how much time, distance and human history went into the formation of each phase in the development of the araucanian hen much less the Polynesian identity. It is my intention to raise the profile of this enigmatic breed and encourage people to conserve the heirloom lineages- even if they are domestic American- generic American- just try and put it in perspective.

Ok my last post. We've discussed the origins of the feathered faces and earrings of the Araucanian hen and the tinted egg.
We have also talked about the origin of the Polynesian culture as a melting pot between two former competing ethnicities and how the two respective parental cultures carried two chickens with two different mtDNA signatures- that is female DNA identification. The first peoples to colonize the islands carried Gallus bankiva ( more than a subspecies- closer to a semi species) from Java and Sumatra. The second peoples to migrate into the sea carried the mainland Gallus gallus ( the Philippines and Burmese races). The first group tended to carry hybrid ceremonial roosters along with their yard birds. The second group may have as well- especially those that they carried from islands they attacked and held dominion over. The hybrid roosters were less genetically compatible with the Gallus gallus hens and consequently left fewer offspring. Nevertheless, in time, just as the Melanesians mixed with the Southern Mongoloids to become a new race " The Polynesians" their island fowl became a new race as well. Just as there were remote islands where Melanesians or Southern Mongoloids lived with their original plants and animals- and with very little mixing with one another- so too are there populations- or specimen skins and descriptions for the most part- of unique island populations of fowl that were for all intensive purposes, endemic to their rocky isles or rainforested volcanic craters.
Those birds and the native people of Rapa Nui managed to reach the western coast of South America at least a few dozen times and some must have made their way back to Rapa Nui as well.

Since the very first day the Araucana was described, it has had "willow"," slate" or dark blue legs. This phenotype is is the product of the yellow genes discussed in the academic papers at the beginning of this thread.

Selective breeding of fertile Bekiko results in the dramatic increase in tail length and saddle covert length due to its inheriting the the Green JF's Non-Moulting gene.



Pré-Columbian (Araucana) New Finding - Page 1 P

That is my bird that I produced without using any recent green JF introductions, only selecting for the other green JF traits to enhance my long-tail line and that bird was a byproduct.

Normally I would handle this sort of thing through private e-mail, but considering it has taken place on a public forum, I will handle it here.

I would guess that it's likely fair to say that you have not obtained permission for use on at least 99.999% of those images, or asked for the facts behind them?

I have no problem with my images being used for educational purposes, if proper credit is given, the facts are correct, and I am notified where it is to be used. However, I do have a problem with people who think they have a right to anything they come across online and think they can do anything they choose with it. You do not automatically have a right to my images.

My image is even watermarked with my logo and you still lifted it without asking! It isn't as though you didn't know who the photo belonged to so that you could ask or find out exactly what the bird is, because we have had run ins before. And then you wondered why I want nothing to do with swapping birds with you? Add this to the reasons. This is over the line.

If you can't at least ask; then breed your own birds, photograph your own work, and quit feeding off of everyone else. As a former member of the ACA (left due to my inactivity with the breed), I can not believe they allow you to pull this here. I thought everyone would be wise to you by now.

Well David,
That is really an informative post that you have provided that speaks volumes for itself. I apologize for using your photo, which I assumed since it is watermarked, is already clearly identified. It was sent to me. I recognized it from your website and realize now that I should have written and asked you permission before reposting it here. It is posted around the internet in many places- especially amongst Japanese poultry science students that recognize the generation of your hybrids. You could have sent me a private email but instead chose to denigrate the forum with this insulting diatribe. I can't pretend to comprehend your last comment but will most certainly remove the photo of your hybrid long tail from this forum. I certainly meant no harm in posting it here, indeed my intentions are not as you perceive them at all. This is an educational thread and the photo certainly illustrates the points of the papers referenced here. Many of these photos are mine and I gave myself permission to use them. Thank You. I apologize to Araucana Club of America members for having unwittingly initiated mean spirited messages that are inappropriate for young people to read and for having committed such a terrible offense as I must have in writing here in haste. It is bad manners to post photos without appropriate permission. The objective of this thread is to discuss ideas that relate to the very complex issues of genetic inheritance of specific traits in domestic chickens. I wanted to present photos that illustrated the points of the various academic findings -and do so in haste. Nothing that has been written here using these informative photographs is any way derogatory or spiteful. It will remain a mystery to me why anyone would react in such a volatile manner. That said, has anyone besides me noticed that the internet brings out the best and worst in people? We could all practice better manners when posting on a public forum. I have obviously elicited a negative reaction by this person whose feathers have been ruffled for legitimate reasons. I used his photo without his permission. To take the added step of being intentionally insulting is offensive to everyone reading this thread and well out of context and scale of the offense. Say the word and I'll erase all my contributions here. Given the number of people that have evidentially read the thread, it would appear that it has been informative and interesting to a large number of people. Isn't it our responsibility to produce informative material that invites people to use new critical thinking skills? For those of us with a higher education, concerned with the paucity of new generations of conservation poultiers, it is up to us to keep people interested in maintaining poultry or other birds. It is up to us to keep up with David Attenborough's generation of fascinating documentaries on the discovery channel if we want to educate young people on the intrinsic value of old cultural heritage breeds- no?
There is a tendency in the internet forum realm for overblown rhetoric. In my opinion, these remarks you've made are completely out of proportion.
And really, swapping birds with you? My birds came directly from Dr. Yamashina and Dr. Iwamiya. Why would I need to swap birds with you?
Oh that's right- I offered to donate the stock , which I inherited the stewardship of, and your clique of tiny minded myopics cringed at the idea of breeding loan agreements which are common place amongst serious conservationists. You then took the unusual step of spitting up a misinformation campaign about my character which is neither accurate nor quantifiable. Just because you dislike someone that you do not know and have never met, but have decided you disagree with, does not make them bad people of low moral fiber. I appreciate that people are territorial about their stocks and selective breeding regimes, but willful ignorance and mean spirited gossip would never dissuade a serious minded individual like myself from the objectives of rigorous conservation/ education and/or discussions of selective breeding. I'm not selling anything here. So why are you threatened? These are the ideas of well respected scientists of the Yamashina Institute of Ornithology and other sources of hard science- not my own. I have been grateful to have the authors of the papers explain their findings in depth and honoured to have been involved in their research from time to time. I wrote here to help explain some questions posed by various individuals that have written me about specific discoveries which have been published in various magazines like National Geographic, Modern Science and Archeology.
I'm beginning to think that borderline personality disorders are consuming the avicultural discipline. All too often, truly volatile things are shot out like rapid fire from an automatic weapon in public forums and by people that really couldn't possibly be that ogreish in real life. Has anything so terrible occurred here that you would intentionally alienate or intimidate readers? Are you really willing to scare off future generations of poultiers- of school kids just for the sake of some pathetic egocentric posturing? There are so few of us left on the planet concerned about these creatures, we really aught to adopt a different set of standards and rules of engagement. We owe it to ourselves. Admittedly, this is my mistake but what could possibly be so offensive that it requires a magnified photo of a cloaca to represent your thoughts? Is this just an attempt to derail the thread? Do you feel that you cannot contribute anything meaningful or helpful to the discussion? This thread is about the origination of the Araucanian hen. This thread is not about you or me or anyone person. This is about ideas and scientific data, some of it controversial. Much of it refutable. It would be a more useful expenditure of energy to stay on topic and leave the personal attacks to private messages. No one intended to slight you David. Photographs are provided to help illustrate what would be otherwise difficult to articulate in short, readily digestible sentences. The internet forum can be an interactive classroom. That is what I use it for. If I were in a classroom in a college, I would be using these same photographs projected onto a wall screen and discussion would be left open and fairly unmoderated. The objective is to foster meaningful dialog and be inclusive in all ideas and questions. These papers have provided us with some tantalizing hints of an important period in human development. Let's keep our conversation civil and avoid histrionics and arm waving.

I'm repeating the same information that I brought forward on this same forum over ten years ago and it was met with consternation and skepticism.
Now there are papers that quantify each and every comment I brought to this forum all those years ago. Not one of the individuals that made such unsavory comments about these ideas in the 90's is here to apologize for their remarks or prejudicial opinions. Its more useful to present the papers now that they are published and just stay current; keep working - keep sharing without meanness or judgment of those people that behaved like they wanted to burn me at the stake the first time around, or the second...I am a firm believer in science.





Exemplary people are even-tempered and clear-minded. Petty people are always fretting.

Hi Kermit,

That's just it, he is not a direct hybrid. Only a descendant of hybrids just like nearly every other chicken breed. That comb he possesses is only a residual ancestral trait that resurfaced. I used no green JF whatsoever to trigger that. There probably hasn't been any used for centuries, or even longer.

>You could have sent me a private email but instead chose to denigrate the forum with this insulting diatribe.>

Why should I have? You didn't bother to e-mail me about the photo. Turnabout is fair play.

>Isn't it our responsibility to produce informative material that invites people to use new critical thinking skills?>

Yes, informative by keeping the facts straight. It's your own fault that you used a watermarked photo out of context and were caught at it.

>And really, swapping birds with you? My birds came directly from Dr. Yamashina and Dr. Iwamiya. Why would I need to swap birds with you? >

Are you denying ever having requested?

1) you wanted to buy birds from myself or anyone I may know
2) when I told you a price you lectured me on how I should "share"
3) you explained the terms of doing a "loan"

You were interested in my birds, you expected something for nearly nothing, and there was no way I was going to trade for (recent JF cross mutt) birds that exhibited none of the traits I like.

As it would happen, I saved those e-mails. Let me refresh your memory:
Sunday, December 17, 2006 6:08 PM
"Do you or anyone you know have five females i can purchase?"

After I told you, "If I did have spares though, I would not let go of any of my best hens for less than $2,000 each with signed agreements regarding various aspects.", you stated, "While I agree the birds are worth 2000.00 and more, the genetic value of the birds in our collection should be in my opinion shared to some extent if we are to introduce the rarer genes into the greater pool."
and you wanted to swap, or each of us "loan", birds to each other as you explained the terms of here (yes, you were right about this part) -
Thursday, December 21, 2006 9:28 AM
"Sending an animal away on loan rarely if ever brings it back to you unless requested. Like pieces of art on permanent loan to various museums the animals remain at the institution until they decide to part with them many years later."

After I told you my price, and you lectured me on how I shouldn't charge and should "share", you had the nerve to tell me you spent $4,300 to get a bird from Hawaii. While you more or less wanted my birds in exchange for mutts by that supposed hen and JF x's! #1 rule if you want something from someone, don't degrade their work.
Thursday, December 21, 2006 9:28 AM (from same e-mail as above)
"I just purchased an onagadori hen for 4300.00 from Hawaii."

>Oh that's right- I offered to donate the stock , which I inherited the stewardship of, and your clique of tiny minded myopics cringed at the idea of breeding loan agreements which are common place amongst serious conservationists.>

Wrong again! You did explain the terms, but that was ultimately not why I wouldn't trade with you. Also, it was not a "donation", call it what it was, a one-sided swap where you would have gotten birds that already have a good genotype and express the desired phenotype and I end up with crosses with a lot of baggage to wade through and breed out.

"I see. Tomebako boxes are crucial aren't they?"

That statement led me to believe that you had possibly not studied birds in Japan as you claimed, because you didn't know about the traditional rearing methods that my friends in Japan have taught me through mail correspondences.

"IIi just returned home from an extended eight month stay in Japan where I visited with the royal family and worked witht he zoological and cultural treasure ministers on nutrition and management protocols for the countries cultural treasures and rare and endangered pheasant-like birds. "

I know tourists who have came away better informed. Even my friends who visited there mentioned the housing type, and they aren't even poultry people.

This confirmed my reasoning for earlier telling you..
"I'm happy with what I have and have no interest in sharing with anyone who would waste the genes through not caring about the looks of the breed, it's expressed traits, and rearing them in a traditional fashion. "

At that time I had taken a look at your photo albums. Nothing even closely resembled the phenotype of the breed names they were tagged with.

That is why I would not "loan" birds to you. Well, that and earlier e-mails you wrote to a friend of mine.

I'm quite sure you will have a lengthy reply to wiggle out of this and, at the risk of missing some great info, I'm going to leave this to you, the moderators, and other members. Perhaps unless I find anything else in those e-mails where you contradict yourself again. :lol:

Hi Kermit,

That's just it, he is not a direct hybrid. Only a descendant of hybrids just like nearly every other chicken breed. That comb he possesses is only a residual ancestral trait that resurfaced. I used no green JF whatsoever to trigger that. There probably hasn't been any used for centuries, or even longer.

You are contradicting yourself here. While you acknowledge that male Green Junglefowl sires are the prerequisite ancestors of Japanese Long Tailed fowl and that nearly every other chicken breed is a hybrid, your bird is not a hybrid- but only descended of one? Could you please elucidate your logic?

>You could have sent me a private email but instead chose to denigrate the forum with this insulting diatribe.>

Why should I have? You didn't bother to e-mail me about the photo. Turnabout is fair play.
In my mind, this would be turnabout if I intentionally insulted you or your stock or attempted to insinuate something nefarious about your character which I have not. The objective is to educate not denigrate. I don't see forum dialog as a competition.


>Isn't it our responsibility to produce informative material that invites people to use new critical thinking skills?>

Yes, informative by keeping the facts straight. It's your own fault that you used a watermarked photo out of context and were caught at it.

Are you claiming that this thread is not informative? Please point out any points that I've made that are incorrect. This is the objective of a forum.I don't understand how using a clearly watermarked and therefore readily identifiable photograph can be construed as theft. I'm not selling the photograph or any birds that descended of the bird. Indeed, I'm not in the chicken market, don't sell birds and intended the photograph to illustrate a theoretical principle first described by my long time friend and colleague Prince Akishino, who is the cousin of Dr. Yamashina. Namely, that G. varius sires played an integral role in the development of several cultural heritage breeds endemic to Japan but whose haplotypey is to be seen in any number of island races of feral fowl, including those of Easter Island. The genes of the Green JF are where specific traits of certain domestic and land race breeds originated.

>And really, swapping birds with you? My birds came directly from Dr. Yamashina and Dr. Iwamiya. Why would I need to swap birds with you? >

Are you denying ever having requested?

1) you wanted to buy birds from myself or anyone I may know
2) when I told you a price you lectured me on how I should "share"
3) you explained the terms of doing a "loan"

You were interested in my birds, you expected something for nearly nothing, and there was no way I was going to trade for (recent JF cross mutt) birds that exhibited none of the traits I like.


I don't recall lecturing you or anyone on sharing .e.g. Breeding Loan Agreements. My family farm foundation was left a group of invaluable genetic stocks maintained in Hawaii after Dr. Iwamiya's health required him to return to Japan. We had underwritten their research facility for several decades and contributed to their creation of the Chicken Genome Mapping Project and other Yamashina institute initiatives. The stock was donated to us in hopes that we would maintain the lines. It was not convenient or timely for me to take on these birds as it rarely is when elderly collector/horders bequieth you with their life time of chicken treasure. While we do have a few farm facilities, these birds hardly fit in our working farm collection/action plans. It was up to me to find homes for the birds. Because of their intrinsic value, specifically that each bird's entire genome is mapped and coded, we were encouraged to loan out the birds to serious conservation poultiers. We ended up having to pay an exorbitant cost to move the birds from Hawaii including their quarantine and holding. We also were left with unenviable situation of having to sort out the infighting between the elderly Japanese poultiers in Dr. Iwamiya's working group, who each wished that the birds remain with them, even though this was not what Dr. Iwamiya wanted. The fighting over stock by his long time colleagues and friends were the defining factors that resulted in him shipping most of the stock back to Japan and gifting our foundation with the outcrossed and backcrossed stock that had not yet reached the more desirable phase. In other words, we inherited the generations of stock that went into the creation or maintenance of his best lines which were returned to Japan.
Not being Japanese myself, the community of Japanese poultiers were incensed that their cultural treasures were being sent to Americans who they did not want to have what they considered their culture's stock. Frankly, I was in the middle of juggling my own responsibilities in my own life.
Not wanting to burden our foundation further, and out of loyalty and issues of honour and helping Dr. Iwamiya 'save face', I accepted the personal responsibility of taking on the new stock and against my better judgment. Anyone that has visited one of my personal homes knows that wild bird species are my focus. Domestic poultry present a very real risk to the health of my wild and often endangered species. Where would I house them?
What would I do with them? They spent that winter in the screened in porch outside my office above the Townsend village commons. It was humorous if not nightmarish having forty roosters crowing all day, especially the long crowers! Once we found a few places to house the birds, interested parties willing to take the birds and safeguard them, we needed hens as the majority of our inherited stock were roosters. If I didn't know myself as well as I do, I would resent your insinuation that any of my suggestions or dealings were anything but honourable.


As it would happen, I saved those e-mails. Let me refresh your memory:
Sunday, December 17, 2006 6:08 PM
"Do you or anyone you know have five females i can purchase?"

After I told you, "If I did have spares though, I would not let go of any of my best hens for less than $2,000 each with signed agreements regarding various aspects.", you stated, "While I agree the birds are worth 2000.00 and more, the genetic value of the birds in our collection should be in my opinion shared to some extent if we are to introduce the rarer genes into the greater pool."
and you wanted to swap, or each of us "loan", birds to each other as you explained the terms of here (yes, you were right about this part) -
Thursday, December 21, 2006 9:28 AM
"Sending an animal away on loan rarely if ever brings it back to you unless requested. Like pieces of art on permanent loan to various museums the animals remain at the institution until they decide to part with them many years later."


I don't understand what you are inferring that I said here? Its fairly clear. I wanted to permanently loan the stock to serious conservation poultiers. I had no intention of collecting on the breeding loan but it would create the necessary paper trail to justify the expenditures that we made to safeguard the stock to begin with. The birds were a part of Dr. Yamashina's personal collection maintained after his death by Dr. Iwamiya. I mistakenly thought that the American Long-Tailed community would appreciate the infusion of the best genetics and best possible selective breeding regimes. That community took my suggestion to "share" aka breed loan with one another, Dr. Yamashina's stock, in a program that encouraged cooperation over competition, as something somehow nefarious. For any ethical stewardship to continue, stewards need to adopt common rules of engagement. This is part and parcel to the code of conduct of the Japanese and is the foundation of all zoo animal management. There is only so much room in the ark but the breed/species must be maintained. This means responsible conservation breeding by intelligent, experienced conservationists. It would be unethical for me to sell the birds donated to me to look after as a steward, and irresponsible to send invaluable stock to individuals with no intention to safeguard the stock in the manner intended by the original steward. The Longtail community got it into their heads that I was a threat and shut me out with no explanation. I heard about it from my friend Mr. King who shared a laugh with me about it. While I found the whole series of events - which began in 2003, to be frustrating and ironic, I do not judge any of the poultiers who prejudged me based on paranoia and/or short-sightedness. From hindsight, it was very funny. Stories about the four am long crowing sonnet continue around the community to this day, adding to the charm of every day country living in Vermont. There are worse stories for your neighbors to regale with such enthusiasm.


After I told you my price, and you lectured me on how I shouldn't charge and should "share", you had the nerve to tell me you spent $4,300 to get a bird from Hawaii. While you more or less wanted my birds in exchange for mutts by that supposed hen and JF x's! #1 rule if you want something from someone, don't degrade their work.
Thursday, December 21, 2006 9:28 AM (from same e-mail as above)
"I just purchased an onagadori hen for 4300.00 from Hawaii."


Unless you can present evidence that I lectured to you or told you not to charge for your own stock, these are ridiculous charges that are a disservice to us all and an insult to my intelligence. My suggestion, if memory serves me correctly, was that you not charge for progeny of Dr. Iwamiya's stock. I would donate that stock on the condition that it not be sold; that you share the stock with other conservation poultiers in breeding loan agreements. The objective was to make the invaluable stock available to entire Longtail community and not freeze anyone out for not being able to afford them. This is common sense for any ethical steward whose objective is to contribute something valuable to an entire group and not just individuals. And again, your cherry picking of my email is only illustrating your own misunderstanding. It is interesting to me that you refer to Dr. Iwamiya's stock as mutts. They are the result of careful selective breeding by the very same individuals that have published the only scientific papers on the origins of these onagadori breeds to begin with. Onagadori means honourable by the way.

>Oh that's right- I offered to donate the stock , which I inherited the stewardship of, and your clique of tiny minded myopics cringed at the idea of breeding loan agreements which are common place amongst serious conservationists.>

Wrong again! You did explain the terms, but that was ultimately not why I wouldn't trade with you. Also, it was not a "donation", call it what it was, a one-sided swap where you would have gotten birds that already have a good genotype and express the desired phenotype and I end up with crosses with a lot of baggage to wade through and breed out.

This is your opinion which you are entitled to. But your characterization of the exchange reveals a certain amount of misinformation and bias on your part, resulting in a mis characterization which you attempted to perpetuate here. All of this would have been better dealt with in a personal email or private message. That you decided to post it publicly on the Araucana Club of America Forum suggest to me that you have an axe to grind and that this vocation is one of political interest for you. If you were truly interested in the conservation of the breeds, you would spend less time attempting to demonize my character and more energy learning from what I've taken the time and effort to present freely to everyone in the interests of transparency and education.

Friday, December 22, 2006 2:45 PM
"I see. Tomebako boxes are crucial aren't they?"

That statement led me to believe that you had possibly not studied birds in Japan as you claimed, because you didn't know about the traditional rearing methods that my friends in Japan have taught me through mail correspondences.

Tomebako boxes are not utilized by Japanese scientists in the maintenance of gene stock that has been outcrossed and backcrossed; selectively bred for countless generations for the primary focus of scientific experimentation. I have horses but don't ride English. All that posting looks like a waste of energy to anyone that was raised on a Western horse and cattle ranch. Does my not riding English make me less of a horsemen in your eyes? I don't have time or interest in Tomebako boxes and neither did Yamashina or Iwamiya. Their lines were represented by little stripes of electrophoresis gel or in DNA maps. Your assumptions have resulted in your not becoming a steward of stock that Japanese conservation poultiers stand in line for.
This is your loss but says nothing about my attempts to reach out and contribute to your community. It does however, speak volumes about the comprehension level of your clique. It also reflects upon exclusivity and the closed minds that shut out good information despite their best intentions for the cultural heritage breeds that they keep.

Genetic Change in the Polynesian Population of Easter Island: Evidence from Alu Insertion Polymorphisms

E. González-Pérez et al.

Summary

The origin of Pacific islanders is still an open issue in human population genetics. To address this topic we analyzed a set of 18 Alu insertion polymorphisms in a total of 176 chromosomes from native Easter Island inhabitants (Rapanui). Available genealogical records allowed us to subdivide the total island sample into two groups, representative of the native population living in the island around 1900, and another formed by individuals with some ancestors of non-Rapanui origin. Significant genetic differentiation was found between these groups, allowing us to make some biodemographic and historical inferences about the origin and evolution of this geographically isolated island population. Our data are consistent with equivalent and recent contributions from Amerindian and European migrants to the 1900s Rapanui population, with an accelerated increase in the European gene flow during the 20th century, especially since the 1960s. Comparative analysis of our results with other available Alu variation data on neighbouring populations supports the "Voyaging Corridor" model of Polynesian human settlement, which indicates that pre-Polynesians are mainly derived from Southeast Asian and Wallacean populations rather than from Taiwan or the Philippines. This study underlines the importance of sampling and taking into account historical information in genetic studies to unravel the recent evolution of human populations.
Pré-Columbian (Araucana) New Finding - Page 1 Rapanuimaleviolaceous-1
This paper is discussing the pre-Polynesian wave of peoples that first arrived in Easter Island, Prior to the emergence of the Polynesian culture.
The chicken DNA of those islands peopled by this first wave are genetically linked with Gallus bankiva matriarchal ancestors, whilst the islands populated by the second wave, that is, those people that originated in Taiwan and the Philippines carried Gallus gallus .
This how the mtDNA of the early islanders can be distinguished. By the third wave- that is the thoroughly intermixed Polynesian diaspora=Lapita culture- the dominant chicken genome is G. gallus.. Nevertheless, with nuclear DNA we can study the male ancestry of some of the island founders and this generally points to hybrid ancestry originating in Indonesia - a long stop over in Marquesas and Tonga where more genetic mixing took place and some years of isolation, and finally arrival on Rapa Nui- with the already unique stock which in turn would become the progenitors of the South American races of fowl belonging to the Quechua speaking Indian tribes and the Mapuche.

The history is interesting, even if of necessity somewhat speculative. Thanks, Kermit, for sharing your findings and opinions.

True on the first assertion. Not so much on the second. The first birds are D'Anvers which have a rather unique haplotypey. They originated in Indonesia and were carried by the Dutch to the Netherlands and Belgium. They are in many ways analagous with the North American Araucana as a breed with many hundreds if not thousands of years of development by endemic cultures before being transported, renamed and bred to new standards in a new country. The new culture brings the old breed to their country and renames it and new selection begins for traits that are more aesthetic or desirable to the new culture. The Dutch and Belgians completely divorced their new feathered treasure with its origins. It was no longer Indonesian it was Dutch or Belgian. This is compelling because of course the Indonesians did not consider the Sri Lankan history of half the founders of the Indonesian breed to begin with. That is to say, a certain percentage of the selective breeding took place in Java around the port of Bantam, but it should be clear that an integral percentage of that selective breeding time and more significantly the genetic origins of the founders of the Indonesian stock, were from Sri Lanka. The rumpless basket fowl were first developed in Sri Lanka ( Ceylon) at least a half century before the Indonesians had established their Bantam Port. So the Indonesians failed to acknowledge the Sri Lankan origins of their bantam fowl. The " Indonesian" Bantam fowl was much coveted by the Dutch who carried it to Europe. The Belgians acknowledged the Dutch importers a bit but their name suggests that the Belgians really felt that this breed was theirs and theirs alone. Similarly, the Japanese disavowed any foreign origin of their onagadori stock as well, and they did this for culturally intrinsic reasons. The Japanese are the first to acknowledge that theirs has a tendency to be racist against others. Their attitudes about the spice traders and spice islands ( Indonesia) were fairly typical for their day. The Japanese did not want to aknowledge that their most beloved of fowl may have had male ancestors from the spice islands. A new myth was perpetuated that elevated a mysterious pheasant as the missing ancestor of the long tailed fowl. That 'pheasant was an Indonesian endemic - the Green Junglefowl.


It is the nature of the domestic fowl - its capacity to become the sole possession of whomever holds it that has made it most enduring throughout its long lifespan as a domestic species. The North American Araucana is a mirror phenotype of the Argentinian Colloncas de Artes, Gallus inarius. Most of its founders were domestic chickens of European origin- but enough of the Colloncas de Artes demes are present in the NA stock to perpetuate the traits we associate with the original founders stock. Everyone of course realizes that the Argentinians took two different endemic breeds and bred them together to create the Colloncas de Artes to begin with...This is one of those conundrums of selective breeding. Today, only very close inbreeding can perpetuate the novelty expressed by heirloom strains of this new breed. Very little effort has been undertaken to conserve the SA stock except in Peru where Yamashina and his colleagues went to great lengths to collect, maintain and conserve the native aboriginals domestic fowl strains. The Spanish conquistadors had no such interest. They believed that their culture was in every way superior and that any vestige of the indigenous religion must be eliminated to make way for their European ideologies. That any alpacas or llamas or quinoa survived this era is a bit astonishing. But survive and thrive they did. Only the most isolated Indian villages managed to keep their domestic fowl unpolluted by the European breeds. They thought of that Easter Island stock as their own. They never acknowledged that it came from across the sea. To these Indians- each strain was theirs and theirs alone.

The D'Anvers is one of the birds whose Nuclear DNA reveals an Ayam Katai ( G. lafayetti male ancestry X bankiva ) sire and also Ayam bekisar ( G. varius male ancestry x bankiva) sires. These birds in the rumpless form were likely the closest thing living today, of what the first Easter Islanders arrived in the South Pacific, Melanesia and Easter Island with. In other words, this was the level of development of the domestic "basket fowl" which were crowded ten or twelve to a basket and carried about the ocean on canoes by the ancestors of the Polynesians. Basket Fowl were one of three major breed types carried by early sea-farers. Later waves of Polynesians only carried gamefowl, though many of these would have been of mixed ancestry, especially those that originated in Tonga, Marquesas and Samoa.

The second photo is of a Violaceous Rapa Nu/ collected by Yamashina Institute in the volcanic craters of Easter Island. It is one of the three feral fowl morphotypes endemic to the island and whose feathers were used in the famous Easter Island feather cloaks. Its DNA has provided evidence of the Pre Columbian origins of the Mapuche Chickens. In other words, the Rapa Nui fowl was carried to South America where it underwent another extended bout of selective breeding by the same indigenous culture that domesticated and select bred /created the cultivars of over one dozen varieties of corn, potatoes, tomatoes, cotton and so on. It is true that North American Araucanas have come a very long way from this level of breeding. Nevertheless, in the interests of bringing the intrinsic value of the NA Araucana up a few notches the evolutionary history of the breed -should be something acknowledged and embraced. The araucana may prove to be one of the few rare cultural heritage breeds that actually deserves recognition and conservation. When I use the term evolutionary in this useage I am primarily dealing with human artificial selection and skewed selection via founder effect amongst populations of mixed ancestry gallus, introduced and naturalized via natural selection ( bird predators exist everywhere there are birds) on very remote islands and new shores.I would hope that anyone familiar with the artificial selection of food crops and cotton, flax and oilseed can comprehend the same laws apply to the cultivation of domestic animals, even if religious ideology discourages pondering principles of natural selection.

I don't think religious ideology has anything to do with natural selection. Natural selection favors attributes that already exist and respond well to actual environmental conditions. Fact of life. Some might call that evolution, but it really is not, in the sense that the genetic traits selected by nature (or via intervention for that matter) were already there, just not preponderant. Molecules to man evolution is another matter. That would require the simultaneous generation of multiple, incredibly complex, newly encoded information within the DNA, and that just doesn't happen in nature because of the incredible odds against it. The only known mechanism for this type of evolutionary change in nature is mutations. But observed mutations have been nearly always detrimental, not macro-evolutionary. This corresponds very well with two physical laws (not theories) of the universe: the first and the second laws of thermodynamics. I.E., the universe is running down and wearing out, not evolving. And something does not come out of nothing.
For example, the first people lived many hundreds of years and reproduced for hundreds of years because the mutations causing cancer, muscular dystrophy, AIDS, arthritis, and a host of other degenerative conditions had not yet occurred. Add to that the lack of intermediate forms in the fossil record (as Darwin said would support or disprove his theory) and we are left with macroevolution being a belief system based on faith, not actual supportable facts. Much more information on this subject can be found at http://www.answersingenesis.org .

I don't think religious ideology has anything to do with natural selection. Natural selection favors attributes that already exist and respond well to actual environmental conditions. Fact of life. Some might call that evolution, but it really is not, in the sense that the genetic traits selected by nature (or via intervention for that matter) were already there, just not preponderant. Molecules to man evolution is another matter. That would require the simultaneous generation of multiple, incredibly complex, newly encoded information within the DNA, and that just doesn't happen in nature because of the incredible odds against it. The only known mechanism for this type of evolutionary change in nature is mutations. But observed mutations have been nearly always detrimental, not macro-evolutionary. This corresponds very well with two physical laws (not theories) of the universe: the first and the second laws of thermodynamics. I.E., the universe is running down and wearing out, not evolving. And something does not come out of nothing.
For example, the first people lived many hundreds of years and reproduced for hundreds of years because the mutations causing cancer, muscular dystrophy, AIDS, arthritis, and a host of other degenerative conditions had not yet occurred
. Add to that the lack of intermediate forms in the fossil record (as Darwin said would support or disprove his theory) and we are left with macroevolution being a belief system based on faith, not actual supportable facts. Much more information on this subject can be found at http://www.answersingenesis.org .

These are certainly very compelling assertions.

How does the molecular data that uncovers the layers of genetic admixture, founder effect, genetic drift and selective breeding of respective cultures disprove this anathema?

Outstanding pictures and video. I have a number of Hmong friends here in the upper midwest, and can't wait to show them the video - hope to get them to translate what was being said. Of the photos, the one showing a rooster with large enamel white earlobes was of particular interest to me - I didn't realize pure junglefowl would have that much variability in lobes. Not hard to see how Brown Leghorns were bred up from these. Thanks for sharing Kermit.
As for your other questions in the previous post, I'm going to refer you to the scientists at answersingenesis.org , as they can give much more detailed information than I. You can contact them by e-mail from the website, and sometimes they respond on the website, sometimes by return e-mail. Incidentally, their Creation Museum near Cincinnati in northern Kentucky is simply awesome. The wife and I had a chance to visit it last summer. We came away with a much better vision of how it all began and got to this point.

Mike, I have debated about responding to your comments dismissing evolution and promoting a creationist view of how life has come about, as this sort of topic can quickly become contentious. However, in the interest of equal time, I would like to direct those interested in learning about the scientific basis for evolution and natural selection to read the wikipedia entry on evolution http://www.en.wikipedia.org/wiki/Evolution and especially the section on "Mutations".

Mutations can involve not only small changes in the DNA, but duplications of genes and major chromosome rearrangements. Sequences of DNA that can move about the genome, such as transposons, make up a major fraction of the genetic material of plants and animals, and may have been important in the evolution of genomes. For example, more than a million copies of the Alu sequence are present in the human genome, and these sequences have now been recruited to perform new functions such as regulating gene expression.

The wikipedia entry also describes how complex traits like the eye can evolve from simpler structures, and just how new species can form over time through the processes of mutation, natural selection and genetic drift.

This is all I will have to say about the topic.

To be honest Rosalyn, I would have been surprised had you not responded. Welcome to the discussion. The processes you name certainly help explain how speciation occurs. If I may interject just a tiny bit of scripture here, Genesis never says species were created, but that "kinds" were created that reproduced after their own kind. Speciation is an example of microevolution that began with kinds, or evolution in reverse if you will. But horizontal shifts and recombinations of DNA don't satisfactorily explain the origin of life itself nor its upward progression from amino acids to creatures that are far more sophisticated than any computer the mind has conceived. Since it has been impossible or nearly impossible to replicate such processes under strictly controlled laboratory conditions, there is little reason to believe they could have occurred in nature where the complex naturally gravitates to the less complex. I have no problem with evolutionists' points of view, as I once was convinced it was true myself due to my secular-humanist schooling. But I do think most teachers and macroevolutionists could be a little more sensitive to the fact there is another faith-based, plausible worldview. We understand how similar or identical DNA sequences seem to point to common ancestors that are lower in the food chain. The alternate view is that these same DNA sequences point to a common creator.

This photo is a great representation of the variety of egg colors I get from my flock. Sometimes it is difficult to get the true egg colors to show up properly in a photo, but this picture is extremely close to reality. It was taken outdoors without a flash and not edited (except for cropping).
I am making my best effort to breed toward true blue eggs, but with some reluctance -- I sort of enjoy the variety I'm getting right now.
Just wanted to share. :)

Your website is very informative. I now know where a photo that was emailed to me came from! Its unfortunate that the standards for the NA Araucana take it so far away from either of the founding breeds it is derived from- but necessary. The discussion regarding desireable traits is most educational. The longer drooping tufts are the more desireable in the SA and Easter Island subraces. I think that it's imperative that the NA Araucana be bred to this new unique standard to distinguish it from its ancestral founders.
The larger, greyer egg and spotted egg are very similar with some of the eggs I saw in the Nikkei Peruujin museum in Peru and subsequently, the stock we imported.
The Quetero imported into this country will often lay a pinkish. taupe hued egg; sea grey or lilac grey egg.
Pré-Columbian (Araucana) New Finding - Page 1 South_American_Quetero_hen
Pré-Columbian (Araucana) New Finding - Page 1 Quetroheuvos
Pré-Columbian (Araucana) New Finding - Page 1 Pearhut
The Mapuche and Rapa Nui will produce darker eggs- spotted or greyish throughout. Some colloncas, especially the rumpless mapuche/quechua will produce really vivid eggs but their appearance is so far from a North American Araucana it seems like a wasted effort to try and alter their morphotype to meet a standard even if they do produce a much more vivid egg. The female photographed below produces a very vivid blue egg. Her father was a rumpless tufted Mapuche ( with muff and beard) . Her mother was a black tailed and tuftless " Andean" whose greatgrandmother/grandmother ( backcrossed) was a colloncas from Peru. The vivid blue eggs were a product of backcrossing, but the rumplessness and tufts were not present in the birds of each generation that produced the darkest. bluest eggs. In other words, by only selecting for egg colour, we arrived with beautiful eggs but the conformation of the birds does not in any way resemble a desirable NA Araucana. I've included these photos only to illustrate the contrast of traits selected for by poultiers in this country versus those of the countries of origin. Wherwas Quetero are bred for their tufts,long tail and laughing crow, colloncas are selected for their tameness, quiet voices and small size.
Mapuche are bred for the colour of the egg shell and the quechua for the large size. Naturally, all four of these breeds have been combined in one composite or another-the UK Araucana; NA Araucana -thinking outloud here -i just wonder if egg colour is inadvertantly being bred out for conformation-then i see your eggs and realize that you are producing superior egg hues for NA. Would very much like to purchase eggs or chicks from you.

We've discovered a means to improve egg shell pigment through diet.
1.Half the daily percentage off food -that is limit the amount put out per day.
2. Mix scratch grain ~ 50% into daily 40% maintenance pellet or crumble, with 5% dry fish based cat food.
3.Add traditional Mapuche Indian supplement to diet as often as possible:
TRADITIONAL MAPUCHE INDIAN POULTRY STAPLE
Cooked whole sweet potato ( baked) cut in half and stuffed with quinoa seeds, and fish scrapings ( just use sardines in olive oil or few tablespoons of tuna- remember to use whatever the fish is packed in- the oil or water and pour this into the baked sweet potato as well)
http://www.hort.purdue.edu/newcrop/afcm/quinoa.html
http://urbanext.illinois.edu/veggies/sweetpotato1.html

The last integral ingredient is Crab Meal
http://www.fao.org/ag/aga/agap/frg/afris/fr/Data/725.htm
While fish and swine may end up tasting like roadkill ( which is unfortunately what crabmeal smells like) if over fed this material, birds like chickens that grind their food in gizzards before digesting their food do not end up tasting like fish and neither will their eggs. We have been using crabmeal in our poultry feed for decades with no ill effects- so please don't be too scared off by the smell of the stuff. Just sprinkle a few tablespoons of crabmeal over the stuffed potato and ideally one of the stuffed sweet potatoes would be put out every three to four days.
If you would prefer to use a product that has already mixed the crabmeal into something more easily dispensed, Murray McMurray sells a product called Farmer's Helper BabyCakes -an ameliorated suet product designed for breeding pairs and chicks- it contains crabmeal and shrimp meal plus spices like turmeric, cinnamon and cayenne which have health benefits as well as helping it smell better. A single babycake fed out to a flock ( say six- eight birds) per week would suffice. Each hen should consume about a tablespoon of the ameliorated suet product every three to four days for the pigments and trace minerals in the chitin to be turned into useful dietary fiber and energy in the laying hens- Besides the obvious nutritional benefits, the consistent presence of crustacean meal in the diet may help to enhance egg shell colour.
Many studies have been conducted about the colouration of wild bird eggs, from sea birds to song birds and emus. The colouration of the egg shell is highly dependent upon the quality of the food consumed prior to the egg's development and laying.

Results of biliverdin content between different groups
in serum, bile, excreta, shell gland, and eggshells are listed
in Table 1. There was no significant difference in the
pigment concentration in serum, bile, and excreta be-
tween blue-shelled and brown-shelled chickens. In both
groups, biliverdin content in serum was much lower than
that in bile and excreta. Biliverdin content in the shell
gland of blue-shelled individuals was much higher than
that of brown-shelled chickens when the eggs were in
the shell gland (P and the granules increased gradually until cuticle deposi-
tion when both granule numbers declined rapidly. In the
present study, the shell biliverdin content of blue-shelled
chickens was 2.60 nmol/g when the eggs were in the
shell gland, 0.72 times that when the eggs were laid, which
suggested that significant amounts of eggshell biliverdin
had been deposited onto the eggshells 3 to 4 h before the
oviposition.
Trace amounts of coprotoporphyrin as well as biliver-
din, zinc biliverdin chelate, and an increased quantity
of protoporphyrin were found in the eggshells of the
Araucano fowl (Kennedy and Vevers, 1973; Schwartz et
al., 1980), which implied that the product of the porphyrin
pathway was boosted in the shell gland of blue-shelled
chickens by the O gene. In Japanese quail, ce (celadon) was
responsible for the glossy pale blue shell, which resem-
bled the eggshell of the Araucano hen both in the external
appearance and pigment content (Ito et al., 1993). Ac-
cording to the survey by Kennedy and Vevers (1976),
many other species, including the Purple heron, Little
egret, Buzzard, Knysna lourie, and others had blue egg-
shells containing biliverdin. Therefore, the present work
lays a foundation for future research on the blue-shelled
gene and also on the physiological and histological study
of the avian shell gland.

A study on eggshell pigmentation: biliverdin in blue-shelled chickens

Biliverdin is an important pigment in the eggshell of chickens and other avian species. Determination of the biosynthesis site for biliverdin is essential for understanding the biochemical process and genetic basis of eggshell pigmentation. Either blood or the shell gland could be the biosynthesis site of eggshell biliverdin. A segregation population with full-sib sisters genotyped Oo and oo, which laid blue-shelled eggs and light brown eggs, respectively, was constructed in a native Chinese chicken breed. Ultraviolet spectrophotometry and HPLC were used to determine the biliverdin concentration in eggshells, blood, bile, excreta, and shell gland of both groups of chickens. Biliverdin content was significantly different between egg shells of blue-shelled and brown-shelled chickens (P < 0.01). Blood and bile were tested 3 to 4 h before oviposition, and excreta was tested randomly. Results showed no significant difference in biliverdin concentration in blood, bile, and excreta between the 2 groups. In the shell gland, the biliverdin contents for the blue-shelled and brown-shelled chickens were 8.25 +/- 2.55 and 1.29 +/- 0.12 nmol/g, respectively, which showed a significant difference (P < 0.01). Our results demonstrated that blood is not the biosynthesis site of the shell biliverdin. Biliverdin is most likely synthesized in the shell gland and then deposited onto the eggshell of chickens.

Chicks hatched from eggs of hens that are fed these specific nutritional supplements in a consistent basis, through the nesting season- and further decrease the % of daily maintenance fare put out on the days of feed supplementation-
chicks hatched from these unusually nutritious, dark orange yolked eggs, (a large percentage of the females) will theoretically ,in turn, lay darker eggs than their mothers. The reason being that specific genes basically turned off or muted by a constant diet high in gluten and plant based starches are turned back on when the birds are returned to a diet with a specific ratio of nutrients in the ratios described. The mothers will only lay slightly brighter eggs or darker eggs but the daughters nurtured inside the egg, on these specific nutrients, will often produce ( 3 0f 4 in our studies) noticeably darker hued egg shells than those of the preceding generation.

Studies in Chickens Fed a Copper-deficient Diet

Supplemented with Ascorbic Acid, Reserpine
and Diethylstilbestrol1A3

Lafayette, Indiana
ABSTRACT Ascorbic acid, 5 g/kg of feed, reduced growth, lowered hemoglobin
and hematocrit levels and increased mortality in chickens when added to a semi-
purified diet containing 8 ppm copper. A small percentage of birds died of arterial
rupture. Increasing the copper content of the diet 3- and 5-fold counteracted some
what the growth depression by ascorbic acid, more completely protected against
depression of hematopoiesis and completely prevented arterial rupture. In most experi
ments ascorbic acid intensified the effects in chickens of a copper-deficient diet. Al
though incidence of arterial rupture was not always increased, average age to rupture
was consistently reduced by ascorbic acid supplementation. Reserpine and estrogen
did not significantly alter the incidence of arterial rupture in chickens fed a copper-
deficient diet.
D

- Crab /Crustacean meal contains more trace minerals and caratonids;- the sweet potato specific vitamins and minerals- especially the skin-
increase in fat ( fish oil/olive oil/ameliorated suet) and animal proteins results in a higher hatch rate and darker and more brilliantly pigmented chicks which in turn lay more vivid and subsequently more pigmented egg shells.
Not incidentally, we have found that Coturnix Quail, Ceylon and Green Junglefowl produce richer pigmented eggs when their diets are supplemented as well, with Ceylon Junglefowl producing darker ochre hued or reddish eggs with large purple red splotches- occasionally even cocoa coloured shells; Green Junglefowl produce greyish, yellowish or greenish hued shells. The Coturnix egg is both. The colour of an eggshell has been conjectured as an honest signal of females about their fitness and health - so the significance of the egg colour/pattern should not be underestimated.
Since these wild junglefowl were amongst the ancestral progenitors of these tinted egg layers, it seems logical to feed them less like chickens and more like junglefowl, especially prior to and during reproductive season and during the moult.
It will be interesting to learn how mortality rates are effected -either positively or negatively or no effect in those eggs that have been produced by hens that have had their diets tweaked. Chicks dying in the shell, on or before the 19th day, suffering from specific infirmities well known to poultry scientists and many of you here- there is a seventeen % decrease in these mortalities just by increasing animal protein and fat to the diet in our studies and up to thirty % decrease in mortality when breeding pairs were fed whole supplementation - formulated for wild ecological specialist junglefowl. The Mapuche Indian poultry fare is about as close as zoo nutritionists could have come up with for wild Junglefowl- as a supplement- what it was lacking in specific vitamins , dietary fibers, chitin and antioxidants is added with inclusion of the BabyCake supplement.

A colleague just sent me this photo of an Ayam Katai photographed in the Philippines close to the Mariana Islands.
Pré-Columbian (Araucana) New Finding - Page 1 Ayamkataifirefoxgame
An Ayam Katai is derived of Gallus bankiva and Ceylon Junglefowl founders and is one of the more ancient fighting ( ceremonial) game breeds.
The RFLP of the Ayam Katai is found in a sizable percentage of archeological sites - recovered from the bones of fowl buried in tombs.
This matriarchal ancestor of the Araucanian hen ( especially Quetero and Colloncas) is today a very rare breed. It has been thoroughly genetically recombined with the Philippines Red Junglefowl as the Polynesians tended to carry this form of the Red JF with them everywhere.
The Ayam Katai X Philippines Red JF derived game fowl is termed the "Lapita Junglefowl" in reference to its close association with a specific generation of Polynesian seafarers.

Here are a few informative papers on the dispersal and origins of feral and domestic pigs of Oceania and the Pacific.The introduction of pigs by respective waves of different cultures is roughly analogous with that of the Junglefowls. Like Junglefowl, hybridization of feral stock in ancient times requires intensive study of DNA collected from archaeological digs. The oldest layers provide us of evidence of the earliest peoples to arrive on the islands. Their pigs were one of these three closely related species. Subsequent migrants onto the islands often brought a different form of the pig and so we see different genetic markers in each stratum. The feral pigs of these archipelagos will often represent fairly unique populations of mixed ancestry- whose genetics provide evidence of founder effect /genetic bottlenecks. Other islands will be recently admixtured with pigs introduced much more recently by Chinese or European explorers.

Abstract
Human settlement of Oceania marked the culmination of a global colonization process that began when humans first left Africa at least 90,000 years ago. The precise origins and dispersal routes of the Austronesian peoples and the associated Lapita culture remain contentious, and numerous disparate models of dispersal (based primarily on linguistic, genetic, and archeological data) have been proposed. Here, through the use of mtDNA from 781 modern and ancient Sus specimens, we provide evidence for an early human-mediated translocation of the Sulawesi warty pig (Sus celebensis) to Flores and Timor and two later separate human-mediated dispersals of domestic pig (Sus scrofa) through Island Southeast Asia into Oceania. Of the later dispersal routes, one is unequivocally associated with the Neolithic (Lapita) and later Polynesian migrations and links modern and archeological Javan, Sumatran, Wallacean, and Oceanic pigs with mainland Southeast Asian S. scrofa. Archeological and genetic evidence shows these pigs were certainly introduced to islands east of the Wallace Line, including New Guinea, and that so-called “wild” pigs within this region are most likely feral descendants of domestic pigs introduced by early agriculturalists. The other later pig dispersal links mainland East Asian pigs to western Micronesia, Taiwan, and the Philippines. These results provide important data with which to test current models for human dispersal in the region.

Dear ACA members,
Pré-Columbian (Araucana) New Finding - Page 1 Sl_junglefowl_chicks_ps
What are your thoughts on APA breed classes? I have recently proposed that the APA consider creating a new breed class " Oceania" which would include all the South American breeds including U.K. Araucana, N.A. Araucana, Ameraucana, Quechua, Mapuche, Colloncas, Quetero, Rapanui, Hawaiian Junglefowl, Saipan Junglefowl, Huastec and Nikkei fowls and so on. This breed class would symbolize a renewed interest in sustainable agriculture and cultural heritage breeds indigenous to Oceania and the Western Hemisphere. It might also include some of the really unusual breeds known to the most ancient cultures that were traded by early seafarers. The Egyptian Fayoumi and Malagasy Game would fit this description. Upon closer examination of this idea, perhaps " Cultural Treasure" might be a more appropriate breed class. What do you think?

The Lakenvelder Hen's status as a cultural treasure has been completely obscured in its more recent turn as an ornamental exhibition breed. Its progenitive strain was developed in Palestine by a culture with Abrahamic roots which begin in India's Indus River Valley during the Vedic Period.
Citation :
Vedic Age is the period during which the Vedas, the oldest sacred texts of the Indo-Aryans, were being composed. Scholars place the Vedic period in the second and first millennia BCE continuing up to the 6th century BCE based on literary evidence.
The associated culture, sometimes referred to as Vedic civilization, was centered in the northern and northwestern parts of the Indian subcontinent. Its early phase saw the formation of various kingdoms of ancient India. In its late phase (from ca. 600 BCE), it saw the rise of the Mahajanapadas, and was succeeded by the Maurya Empire (from ca. 320 BCE), the golden age, classical age of Sanskrit literature, and the Middle kingdoms of India.
Tracing the Indo-Aryans route from the Indus Valley to Ur in Mesopotamia and on to Palestine, we gain a clear comprehension of the important steps in development of the "Mediterranean" egg production breeds. The Lakenvelder is thought of primarily as a European breed, celebrated for its striking appearance. The following synopsis brings to light some rarely discussed facts as well as conjecture about the origins of some intrinsically important domestic species. This is intended to highlight the domestic 's fowl's significance as a pivotal example of cultural development bridging continents and centuries.

Bos indicus cattle are descended of a different wild ancestor than other domestic cattle. They were also domesticated earlier. These Zebu Cattle were brought from the Indus Valley into Mesopotamia (Ur) , on to Syria and the Levant (Palestine/Lebanon) at the same time and by the same cultural migration as the Indus Valley domestic fowl.

Once Upon A Time,
There was a great civilization in the Indus Valley. This burgeoning culture domesticated their own unique form of wild cattle and kept tamed Indian Red Junglefowl G. g. murghi. The male junglefowl were symbolic of the rising and setting of the sun. The Indus people did not eat the flesh of the chicken nor partake of its eggs early on in its development as it was considered sacred. Most of its uses were tied to religious ceremonies. Many of these ceremonies ended with the death of the bird over an alter or just as often, they fought the males together as a means of divination.

Pré-Columbian (Araucana) New Finding - Page 1 Murghired_jungle_fowlhenaps_filtere
Pré-Columbian (Araucana) New Finding - Page 1 Red_junglefowlmale_with_harem5ashss
The Indian Red Junglefowl was a fine choice because of its close relationship with cattle. The wild junglefowl lived side by side withe wild cattle since their earliest days. The junglefowl are dependent upon the fly larvae that hatch in cattle manure and on the ticks and other invertebrates stirred up by the grazing hoofstock.
Like livestock managers in recent times, these most ancient poultry husbanders had a very difficult time distinguishing one Red Junglefowl from another. Fortunately, brisk trade was developing between Southern India and the Indian Ocean to the south; and between Mesopotamia and the Near East to the west and north. One consequence of the trade was the introduction and infusion of a more thoroughly domesticated strain of Red Junglefowl from South East Asia, descended from Gallus g. gallus.
Pré-Columbian (Araucana) New Finding - Page 1 Vietnamjunglefowl_r_nhb
This new Red Junglefowl from South East Asia was different than the local Indian form in that it was even more vivid in colour; with large showy white earlobes and of larger size. The strains carried into India via Burma, were also more thoroughly domesticated for both meat and eggs as well as fighting. The Indus Valley people interbred the Indian and Burmese Red Junglefowl and produced birds with hybrid vigour. Some specimens were larger than both parents and they developed even faster than the parental forms. What is more, the phenotypic diversity amongst individual flocks could be significant, especially if a few generations of fixed genetics and close inbreeding were in use as mutations like unusually large or multiple serrated combs- the absence or presence of large, showy white ear lobes- the hue of the hackle and secondary wing quills- they could all be effected by a few generations of close inbreeding. Even after a half century of this selective breeding amongst Red Junglefowl composites, the birds were still difficult to distinguish one from another by people with no experience or cultural relationship with domestic fowl. Flocks were essentially identical in the eyes of foreign traders.
This presented a problem.
The Grey Junglefowl inhabits the Ghat Mountains along India's western coast line right up into Pakistan. It witnessed the domestication of its sunny cousin and lived in the same valleys on the very outskirts of the Indus Civilization's settlements. As the early flocks of Red Jungefowl composites were generally closed, with very few male founders- with one highly esteemed or prized male to a half-dozen or more females- it probably presented a temptation to the Grey Junglefowl living in the same valleys and forests as the early Indus civilization. Juvenile and unpaired male Grey junglefowl, probably did then what they are still doing today in nature. Wild Grey Junglefowl regularly enter villages and fields, foraging together with local domestic fowl. The Grey Junglefowl males breed the domestic fowl and produce hybrids who tend to remain in the human environment of their tame mothers as survival is so poor for them in the jungles.
Pré-Columbian (Araucana) New Finding - Page 1 Grey_jungle_fowl_rs
We will probably never know when the first Grey Junglefowl rooster crossed the threshold and mated with an Indus Valley semi-domesticated hen. We do know that the bright yellow legs of the Grey Junglefowl were soon passed on to the majority of the primitive Indus Valley Game Fowl- the first recognizable breed to be developed in India. The Asil is a descendant of that stock and so are all the chicken breeds you have seen with yellow legs.
Pré-Columbian (Araucana) New Finding - Page 1 Bengalrooster
The first generation hybrid between Grey and Red JF looks remarkably like the Ceylon junglefowl. A hybrid like this would have been much coveted by ancient merchants because of its unusual appearance and voice. We can be assured ( based on molecular evidence) that these unusual looking roosters were traded further than more typical looking male Red Junglefowl composites. Regardless, the majority of the founding bloodlines of the Indus Valley fowl were derived from Indian and South East Asian Red Junglefowl. Only a very few Grey Jf roosters probably ever were used in the development of the Indus Valley fowl. Line breeding using these hybrid roosters to the exclusion of Red JF sires would result in the dominant expression of certain genetic traits unique to Grey JF.
Once the Indus Valley fowl were transported far afield to new countries like Mesopotamia , which was their next stop, a genetic bottleneck would soon be in effect. Limited numbers of male founders- and these being partially Grey Junglefowl in ancestry, meant that certain traits not found in Red Junglefowl became fixed early on in the development of the earliest domestic races of Near Eastern chickens.
Pré-Columbian (Araucana) New Finding - Page 1 0617-08MoaCock
For example, many of the Indus Valley Games brought to Mesopotamia from India probably had yellow skin and yellow legs. They probably were otherwise very much like the Red Junglefowl in appearance.
Subsequent generations resulting from close inbreeding will eventually have produced sports exhibiting new and unusual mutations like dark and buff plumaged hens
Pré-Columbian (Araucana) New Finding - Page 1 Bengalhens2
and/or the occasional grey-barred ( crele) male plumage like this Gar Creek Penedesencas Rooster which is in effect, a throw back to a Grey Junglefowl ancestor:

Pré-Columbian (Araucana) New Finding - Page 1 Grey_jungle_fowl__gaurav_bhatnagar
At any rate, and no I have not forgotten about the Lakenvelder, the Indus Valley Game Fowl was transported to Mesopotamia in ancient days where it underwent more refinement as a domestic species tied completely with human kind. From Mesopotamia, the now Mesopotamian Dual Purpose phase of the Indus lineage, would eventually be carried over land to the Tigris and Euphrates Rivers, and Syria- to the southern eastern shores of the Mediterranean Sea. The Indus Valley stock came to rest for a very long while in the hills of Palestine which linked the Mesopotamia with the Mediterranean and Egypt. This fairly small and very homogeneous (closely related individuals) population of domestic fowl were likely the only breed of chicken known to the ancients of the Near East at this point in time.

Pré-Columbian (Araucana) New Finding - Page 1 Image002
Pré-Columbian (Araucana) New Finding - Page 1 Megiddo-map-large
By now our Indus Valley lineage has been transformed by centuries of close breeding between highly valued stocks which all shared a common ancestry in history.
Chickens were so valuable in these days, only the elite could afford to own them. This meant that flocks were closed and they remained within powerful families ( often royalty or religious leaders) for generation after generation. Its difficult to say just what these ancient stocks looked like but they probably looked like these birds I've discovered perusing the internet, which are Egyptian Fayoumi bred to Games. This is, in effect, like going back in time and erasing the special traits that make each different breed unique and in doing so recreating the common ancestor of both. Not incidentally, the major gene stock of domestic chickens to be brought into Egypt during the 18th Dynasty ( circa 15th Century BCE) came from Tel Megiddo as tribute to King Thutmose III. These Levantine fowl are the primary ancestors of the Egyptian Fayoumi.

Getting back to the Lakenvelder, the refinement of the Indus Valley fowl in the Levant was of critical importance.
From this stock emerged all Mediterranean breeds as well as the Egyptian Fayoumi.
Romans carried this stock throughout the Mediterranean and Romans of Jewish descent carried their cherished Tel Megiddo fowl to the Westfalen region of Germany.
Pré-Columbian (Araucana) New Finding - Page 1 Westfalen_im_Deutschen_Reich
These early settlers to Germany were gifted bakers and the Tel Megiddo hen was further refined in Westfalen as a superb producer of baking eggs.
Pré-Columbian (Araucana) New Finding - Page 1 Bantam_Lakenvelder_Cockerel

When I saw the Lakenvelders in their exposition cages I waited to hear any vestige of their history by the judges or the poultiers competing for ribbons. There was no discussion of the cultural history of the bird and not a single person that I asked knew anything more about the breeds than what is written on the order sheets of your favorite hatcheries. Feathersite remains as the better reference for chicken breeds.
But what can we do to impart the significance of each cultural heritage breed when the vast majority of people keeping them do not appear intellectually curious?

Ok- I realize you are probably all wondering how and why I could go on and on about a breed of chicken that is not even remotely related to our beloved Araucanians. I'm writing about the Tel Megiddo/Lakenvelder and soon the Egyptian Fayoumi to make some really important points about the origins of ALL domestic fowl. The APA is concerned with pure breeding of standard breeds. So much has been based on faulty information- that is the origin of the domestic chicken- its supposed single ancestor the Red Junglefowl- etc. that we get to a point where people don't realize that the history of domestication of every single breed is founded on hybrid stock followed by close genetic inbreeding. In other words, if there had been no crossing between the Indian Red and Burmese Red; the Philippines Red and the Indonesian Red there would be no basic stock from which all domestic chicken breeds would eventually be refined from. Consequently, it should be of little surprise that very early on in the domestication of the chicken, that is some several thousand years ago, the males of each and every one of the other wild junglefowl species were utilized in the development of one breed or another.
Pré-Columbian (Araucana) New Finding - Page 1 Murghipossiblywithsonnerati
Pré-Columbian (Araucana) New Finding - Page 1 Ga_choi
In order to conserve these highly refined breeds - all these thousands of years later- we must breed them true- and this requires that there be standards (when appropriate/applicable). Further improvement of breeds is the next issue- as improvement for exhibition all too often conflicts with selective breeding for the enhancement of egg colour/size and shape; improvement for survivability ( in the face of predators) etc.. In my opinion, we have elevated the value of the exhibition stock without making much attempt to find or even explore consensus on just what it is that defines a breed. For me, the Tel Megiddo/Lakenvelder is a prime example of collective forgetting.
For people native to the Near East, who would immigrate to Europe and introduce with them the miraculous bird that produced eggs.
I don't mean to belabor the point, but of course eggs were indispensable in the creation of a whole new cornucopia of baked goods.

In ancient history, the first evidence of baking occurred when humans took wild grass grains, soaked them in water, and mixed everything together, mashing it into a kind of broth-like paste. The paste was cooked by pouring it onto a flat, hot rock, resulting in a bread-like substance. Later, this paste was roasted on hot embers, which made bread-making easier, as it could now be made anytime fire was created. Around 2500 B.C., records show that the Egyptians had bread, and may have learned the process from the Babylonians. The Greek Aristophanes, around 400 B.C., also recorded information that showed that tortes with patterns and honey flans existed in Greek cuisine. Dispyrus was also created by the Greeks around that time and widely popular; was a donut-like bread made from flour and honey and shaped in a ring; soaked in wine, it was eaten when hot.
Baking flourished in the Roman Empire. In about 300 B.C., the pastry cook became an occupation for Romans (known as the pastillarium). This became a respected profession because pastries were considered decadent, and Romans loved festivity and celebration. Thus, pastries were often cooked especially for large banquets, and any pastry cook who could invent new types of tasty treats was highly prized. Around 1 A.D., there were more than three hundred pastry chefs in Rome, and Cato wrote about how they created all sorts of diverse foods, and flourished because of those foods. Cato speaks of an enormous amount of breads; included amongst these are the libum (sacrificial cakes made with flour), placenta (groats and cress), spira (our modern day flour pretzels), scibilata (tortes), savaillum (sweet cake), and globus apherica (fritters). A great selection of these, with many different variations, different ingredients, and varied patterns, were often found at banquets and dining halls. The Romans baked bread in an oven with its own chimney, and had mills to grind grain into flour.
Eventually, because of Rome, the art of baking became known throughout Europe, and eventually spread to the eastern parts of Asia. Bakers often baked goods at home and then sold them in the streets. This scene was so common that Rembrandt illustrated a work that depicted a pastry chef selling pancakes in the streets of Germany, with children clamoring for a sample. In London, pastry chefs sold their goods from handcarts. This developed into a system of delivery of baked goods to households, and demand increased greatly as a result. In Paris, the first open-air café of baked goods was developed, and baking became an established art throughout the entire world.
We chicken aficionados can add something to the above reference on baking- and that is the introduction of the egg. It absolutely transformed the cuisine of every culture that adopted the domestic chicken. Eggs made everything from pasta to bagels possible.
Its difficult for us to imagine what the world was like before the advent of the egg production laying breeds.
Perhaps we take the chicken for granted as badly as the rest of the population. When I saw those Lakenvelders on exhibit at the Big Chicken Jamboree or whatever it was called in Indiana, it nearly broke my heart- not because I thought the birds were uncomfortable in their show cages or not being cared for by their handlers. I was disturbed with the complete indifference this modern culture has for the hard work and dedication, the tireless maintenance and refinement of the ancient breeds of our ancestors. If it hadn't been for the Indus Valley Civilization and South East Asian cultures, like those of Vietnam and Burma, we would never have known any sort of domestic chicken.
A few centuries later, the migration of the Indo-Aryan wise men( who after arriving in Ur came to be known as the Avraham, short for Holy Men of the Brahmanputra river) into the Near East, led to an eventual burgeoning cultural diaspora that would eventually give birth to the Hurrian Mittani, the Hebrews of the Levant and Ethiopia. Many people know the name Abraham/Avraham/Abrahm/Ibrihim but few of them know the origins of the name or place it in time or place preceding the Judeo-Christian and/or Islamic religious history. We can literally trace the origins of the name Abrahm onto a world map and compare and contrast it with the migration of the domestic chicken from the Indus Valley -across Mesopotamia to Syria and Palestine- and from there to Egypt and Ethiopia on the one hand and across the Mediterranean on the other. This ancient branch of human culture, grew more complicated over the centuries, splitting out into ever finer distinctions and cultural identities that just about no one can make sense of today. People always seem to be fighting over Tel Megiddo in Palestine- and dividing up its treasures. But the Tel Megiddo hen, mother of all Mediterranean chicken breeds, from the Egyptian Fayoumi to the Minorca, to the Leghorn and the Penedesencas, the Campine and other Frankish breeds-its also the mother of Ethiopian chicken breeds which I won't get into at this moment- Regardless, this Lakenvelder/ Tel Megiddo deserves to be better known than just some fancy show chicken that carries the dubious title of " Shadow on a Sheet". This showy and highly refined phase well known by all to anyone that has ever picked up a hatchery catalog, has an ancient history which is connected to all of us for its central role in the development of all Mediterranean breeds.

So we've covered some ground on the Lakenvelder and if you care to rewind your memory card a bit, you may recall that long before there was such a refined confectionery heirloom of a breed as a Lakenvelder, there was a fortress city in the Levant called Tel Megiddo which bridged Mesopotamia and the Indus Valley Civilization with the Mediterranean Sea and Egypt. Before there was such a breed as the Lakenvelder, the "Tel Megiddo Phase " at the foundation of the Lakenvelder's development underwent sufficient homogenization, that is, the vast majority of all the chickens living in the Levant at this period were exceedingly closely related. While they may not have been particularly tame or pretty, they bred true - in the sense that one of three or four phenotypic morphs were all that would hatch from each clutch and each morph could be bred to type for those that were so inclined. We must remember that use of the domestic fowl at this stage was largely ceremonial. Its rooster crow was considered at the time as its crowning achievement. Its propensity to stick around and entertain with all its antics and the beauty of the birds were not lost on the ancients either. If anything, people probably searched for excuses to keep their showy pets . The daily production of eggs was also fascinating and useful, but there simply were not enough chickens about, at this level of domestication, to jettison them to the indispensable category where they are today. Only the royal and religious classes were familiar with the domestic fowl at this point in time and history.

In order to understand the development of the Egyptian Fayoumi we have to rewind a fair bit, to revisit ancient Egypt and get a handle on a place known by archaeologists and world historians as the Egyptian Labyrinth. It was built quite a bit earlier than the development of the hills of Palestine which would eventually become the fortress of Tel-Megiddo. So we have to go back in time a few thousand years before the first chicken arrived even in the Levant - much less Egypt.

The Egyptian Labyrinth

Pré-Columbian (Araucana) New Finding - Page 1 Figure3
The first recorded maze in history was the Egyptian Labyrinth. Herodotus, a Greek traveler and writer, visited the Egyptian Labyrinth in the 5th century, BC. The building was located just above Lake Moeris and opposite the city of the crocodiles (Crocodilopolis). Herodotus was very impressed by it, stating, "I found it greater than words could tell, for although the temple at Ephesus and that at Samos are celebrated works, yet all the works and buildings of the Greeks put together would certainly be inferior to this labyrinth as regards labor and expense." Herodotus added that even the pyramids were surpassed by the Egyptian Labyrinth.
Pré-Columbian (Araucana) New Finding - Page 1 Fig001

Paul Lucas sketched this drawing of the remains of the Egyptian Labyrinth in 1700.

Herodotus was told that the land of Egypt had been divided into twelve kingdoms, or nomes, each ruled by a king. The kings had come together to leave a memorial of themselves through this temple which was called Arsino�, which means "the temple at the entrance of the lake." The entire building was surrounded by a wall and contained 12 courts with 3,000 chambers. The roof of the temple was composed of stone and the walls were covered with sculpture. On one side of the labyrinth was a pyramid 243 feet high. The temple was in two levels with half of the rooms above ground and the rest below. Herodotus was guided through the upper part of the labyrinth, but was not permitted to go underground. He was told that the rooms below contained the bodies of the kings that constructed the temple and the tombs of sacred crocodiles.

The ancient writer Pliny in his book "Natural History," written in the first century AD, also talks a little about this labyrinth. He noted that the labyrinth contained palaces and temples to all the gods of Egypt as well as "banquet halls reached by steep ascents, flights of ninety steps leading down from the porticoes, porphyritic columns, figures of gods and hideous monsters, and statues of kings." Pliny goes on to say, "Some of the palaces are so made that the opening of a door makes a terrifying sound as of thunder. Most of the buildings are in total darkness."

Little remains of this once-impressive structure today. In 1700 a European traveler named Paul Lucas visited the site and published an account of the remains, including sketches, as he saw them. Over a century later K.R. Lepsius led an expedition and uncovered a series of brick chambers which he identified as the labyrinth. The location was not definately determined until Professor Flinders Petrie explored the site in 1888. Petrie identified the wall found by Lepsius as the remains of a Roman town and then went on to find the foundation of the actual labyrinth which measured 1,000 feet long by 800 feet wide.
Archaeologists now believe that the temple was built by Amenemhat III around 4,000 years ago and the mummified remains of Amenemhat and his daughter have been found in the associated pyramid. The exact purpose of the building is still a matter of speculation, but one thing is for sure: it is the oldest-known structure to which the label labyrinth has been applied.

Pré-Columbian (Araucana) New Finding - Page 1 Cattle_Ankole
Bos indicus or Zebu Cattle originally from the Indus Civilization were introduced to Egypt at the same time as the Indus Phase domestic fowl. Subsequently, the Zebu Cattle were interbred with Egyptian Cattle whose wild ancestor was native to the Nile Valley and Eastern Sahara. The recombined stocks gave rise to the East African Cattle known as the Angkole and Watusi Cattle. Ancient Egyptian art reveals that the arrival of the Indus Valley Cattle coincides with the New Kingdom which like the introduction of the domestic fowl to Egypt, occurred during the 18th Dynasty. .
The Egyptian Fayoumi is like the Lakenvelder, an ancient breed derived of the Indus Lineage stock. The Tel Megiddo and the Egyptian Fayoumi split from the same family branch somewhere between ~ 1425 and 1397 BC. which is approximately three thousand, five hundred years ago.
Their common ancestral heirloom lineage, which will be referred to here as, "Indus Phase" was refined durings it short stop over in Mesopotamia (Ur) before its eventual transmigration to Palestine . Once in Palestine, this stock underwent several levels of refinement in the Tel Megiddo ( Har Megiddo) region. Here in these fortressed valleys, the Indus Heirloom lineage and root stock of the domestic fowl was maintained to the exclusion of all other domestic chicken breeds. No other breeds had yet to be developed in this part of the world. The Egyptian Fayoumi was developed from one phase of the Indus Lineage which was relatively primitive ( " early Tel Megiddo phase) whilst the Lakenvelder and other Mediterranean breeds were bred from a much more refined phase of the same stock ( final Tel Megiddo phase), many centuries later.
We know from the annals of history that greatly esteemed roosters and hens of this early "Tel Megiddo phase" of the Indus lineage were presented as tribute to King Thutmose III during the mid 18th Dynasty ( 14th Century BCE). As the Egyptians had never before seen a chicken, it was met with no little fanfare. Subsequent to its arrival in Egypt, this Tel Megiddo Phase stock of the Indus Lineage fowl underwent yet another transformative and uniquely African phase. The Egyptian chapter culminates with the development and refinement of our beloved Egyptian Fayoumi, which is one if not the most important egg producing breeds in all of Africa. This is the first and only breed that was developed primarily on the African continent. Many people fail to realize that Egypt is on the African continent.
So how did we get to the Fayoumi and how does it differ from the Lakenvelder -and while we are at it- how does it differ from the Campine?
Let's get down to brass tacks with the naturalization of Gallus domesticus in Egypt.
As the ancients lacked proper chicken coops, or aviaries, these newly imported curiosities- were released into the high walled gardens and sacred groves surrounding the Egyptian labyrinth, which sprawled across many miles in the Fayoum Oasis/marshlands. Due to the primitive state of the stock, that is, they were not all that domesticated to begin with, these semi-domestic flocks quickly went feral, as chickens are prone to do when given the opportunity. With each generation, they further reverted to wild type eking out a survival in the wild marshes and thorn forests where the birds quickly became naturalized as a feral species. This reversal in terms of domestication, the chickens of Fayoum Oasis were reverting to the wild as opposed to becoming more domesticated, more essentially useful to human kind, this was happening for two major reasons.
1. the religious caste of Egyptian priests who were the stewards of the Egyptian Labyrinth were strictly vegetarian, eating neither fat, nor flesh, eggs or fish. They had no active participation in the development of the Fayoum chicken, save for protecting them against poachers and predators and providing them with sanctuary and food, which were essentially the same things the high religious caste of the Indus Valley had done for their first semi-domestic cattle and fowl a few chapters earlier.
2. The first Fayoum fowl were skittish and wild to begin with. Their male ancestors were largely Grey Junglefowl hybrids. The thorny marshes and palm groves of Fayoum were ideal habitats for those individuals with Grey Junglefowl instincts and survivability skills. Native predators helped sculpt the reversal the rest of the way. It wasn't until Cleopatra's Greco-Roman era, nearly a thousand years later, that the wild fowl of the Fayoum Oasis were captured up and re domesticated as it were. Im skipping ahead a bit so let me keep editing this for clarity without further confusing the chapters in history.
Pré-Columbian (Araucana) New Finding - Page 1 EgyptianLabyrinthMap
To reiterate once again, the original stock that gave rise to the modern Fayoumi was, at the time of their introduction to Egyptian, still fairly close to the Indus Valley phase and this means that while they came from Tel Megiddo in the Levant, they had not yet reached the level of development in domestication that the last few incarnations of the Tel Megiddo lineage would, before being carried across the Mediterranean and into Europe to become the basis of each and every one of the layer breeds.
The only individuals that survived to reproduce and indeed did breed successfully, were capable of flight and self survival; they resisted periods of drought and knew how to hide their eggs. In other words, when King Thutmose III was sent a few dozen chickens from Tel Megiddo during the mid 18th Dynasty, the birds were not as domesticated and thoroughly homogenized as the stock that would be carried out of Palestine during the Roman era during the era of the birth of Christ. If you can intuit history for a moment- the chickens scratching about in Bethlehem the day Christ was born, these would have been the last Tel Megiddo Phase- which immediately precedes the introduction of the domestic fowl to the Mediterranean and Europe. During the early Tel Megiddo Phase, nearly 2000 years before the birth of Christ, Gallus domesticus in the Levant = and these were the only chickens in the Near East at that time, were barely domesticated- closely bred because of the very small founder pool of their progenitors- but nevertheless, only a few stages from being wild junglefowl.
At the time of their arrival in Egypt during the mid 18th Dynasty, during the early Tel Megiddo phase, they would have been similar in size and shape, to the Red Junglefowl, perhaps a bit larger, with just a few telltale traits that would set them apart from that wild species.

Something that likely distinguished this stock from the Red Junglefowl progenitors-would have been the markings of the females, which may well have been patterned slightly differently than a typical Red Junglefowl because of the Grey Junglefowl sires in their ancestry. Grey Junglefowl females are camouflaged in exceedingly dry evergreen hill forest. Red Junglefowl females are camouflaged for life in tropical deciduous forest. The Grey Junglefowl female's dorsal plumage is strikingly marked with vivid pale centers to each feather- the breast is even more boldly patterned in highly contrasting white and black markings which serve to conceal her while perched in the thorn forest. The Red Junglefowl female lacks any striking demarcations in her plumage as she lives in moister understorey where the leaf litter is deep and she only need merge with the forest floor to be concealed. In other words, the females of the early Tel Megiddo phase probably closely resembled a Modern Game.
