家雞起源於一萬年前的東南亞? (Sawai et al.)

The Origin and Genetic Variation of Domestic Chickens with Special Reference to Junglefowls Gallus g. gallus and G. varius

Hiromi Sawai et al.

It is postulated that chickens (Gallus gallus domesticus) became domesticated from wild junglefowls in Southeast Asia nearly 10,000 years ago. Based on 19 individual samples covering various chicken breeds, red junglefowl (G. g. gallus), and green junglefowl (G. varius), we address the origin of domestic chickens, the relative roles of ancestral polymorphisms and introgression, and the effects of artificial selection on the domestic chicken genome. DNA sequences from 30 introns at 25 nuclear loci are determined for both diploid chromosomes from a majority of samples. The phylogenetic analysis shows that the DNA sequences of chickens, red and green junglefowls formed reciprocally monophyletic clusters. The Markov chain Monte Carlo simulation further reveals that domestic chickens diverged from red junglefowl 58,000±16,000 years ago, well before the archeological dating of domestication, and that their common ancestor in turn diverged from green junglefowl 3.6 million years ago. Several shared haplotypes nonetheless found between green junglefowl and chickens are attributed to recent unidirectional introgression of chickens into green junglefowl. Shared haplotypes are more frequently found between red junglefowl and chickens, which are attributed to both introgression and ancestral polymorphisms. Within each chicken breed, there is an excess of homozygosity, but there is no significant reduction in the nucleotide diversity. Phenotypic modifications of chicken breeds as a result of artificial selection appear to stem from ancestral polymorphisms at a limited number of genetic loci.

看似米和鸡像是东南亚的类尼格利托人最高培育的,要么就是他们带到东亚南部,由类马来人群培育。

看似米和鸡像是东南亚的类尼格利托人最"高"培育的,要么就是他们带到东亚南部,由类马来人群培育。

不太能理解老永怎么就推断出senti人又培育了鸡。

俺读了一下。挺有意思的。
就是样本数太少了。另外还有两种野鸡没加进来也是个大问题。看来打野鸡是不容易呀,世界各地皆然。
最后要是能搞一下世界各地鸡种的传播路线就好了,俺家的老母鸡也可以贡献一毫升鸡血。

你以为新石器以前的东南亚的石头缝里还藏着远东人种?

Yungsiyebu 发表于 2010-5-29 08:55


我在现代类尼格利托人后裔中没有看到有人养鸡,种米的最早在中国湖北,不在东南亚

所以也可能是他们从东南亚带过去的。

家雞的遷徙應該和人類有密切關係, 找了半天還是這裡最適合發了。:lol

这种论调反驳不得,一不小心就会被扣"种族主义"的帽子.人家会说,小黑人就不能最早培育鸡吗?就因为他的肤色和身高?

还有孙悟空,难道鸡不能使我族黄种孙悟空躲在石头缝里偷着培育的吗?咱炖鸡让矮黑闻着味找不到,馋死丫;PP

不是唐僧还没救他呢吗?得中国人+马列毛思想才能称得上中国特色。

与尼格利托人关系密切的波利尼西亚人是养鸡的。

泰文“鸡”读 gaii4 ,同江门新会的“鸡”读音完全一样。广州话“鸡”读 gaii1 ,广西壮族读 gaii3(“继”)。

养鸡倒不用太正规的条件,我爸以前当兵时,他们部队养的鸡都是白天散养在山上,晚上赶回鸡棚几乎不用人工喂食,比养猪方便多了.

谜雾 发表于 2010-6-1 14:20

鸡的主要天敌是黄鼠狼,不怕老鼠的.过去农村里的鸡都是散养.

谜雾 发表于 2010-6-1 14:46

我怀疑你看到的大老鼠就是黄鼠狼.或者是美洲传来的麝鼠.

最早養雞的新石器遺址還包括黃河流域和印度河谷, 年代起碼在八千年前。

"The origins of domestic chickens (Gallus g. domesticus) have been debated ever since Darwin . Archeological remains of domestic chickens are found in 16 Neolithic sites along the Yellow River in Northeast China as well as in the Indus Valley. Because some of these remains date back to ~8,000 years ago , domestication must have been undertaken at least since that time. It is suggested that domestic chickens originated from junglefowls in Southeast Asia."

游猎的类尼格利托人培育鸡怎么培育?一边走一边孵蛋?喂它们什么?大米饭?象麦当劳那样装在笼子里四处走?鸡又不是牛马羊,可以放牧着走。
