Genetic origins of the Ainu inferred from combined DNA analyses of maternal and paternal lineages

Abstract
The Ainu, a minority ethnic group from the northernmost island of Japan, was investigated for DNA polymorphisms both from maternal (mitochondrial DNA) and paternal (Y chromosome) lineages extensively. Other Asian populations inhabiting North, East, and Southeast Asia were also examined for detailed phylogeographic analyses at the mtDNA sequence type as well as Y-haplogroup levels. The maternal and paternal gene pools of the Ainu contained 25 mtDNA sequence types and three Y-haplogroups, respectively. Eleven of the 25 mtDNA sequence types were unique to the Ainu and accounted for over 50% of the population, whereas 14 were widely distributed among other Asian populations. Of the 14 shared types, the most frequently shared type was found in common among the Ainu, Nivkhi in northern Sakhalin, and Koryaks in the Kamchatka Peninsula. Moreover, analysis of genetic distances calculated from the mtDNA data revealed that the Ainu seemed to be related to both the Nivkhi and other Japanese populations (such as mainland Japanese and Okinawans) at the population level. On the paternal side, the vast majority (87.5%) of the Ainu exhibited the Asian-specific YAP+ lineages (Y-haplogroups D-M55* and D-M125), which were distributed only in the Japanese Archipelago in this analysis. On the other hand, the Ainu exhibited no other Y-haplogroups (C-M8, O-M175*, and O-M122*) common in mainland Japanese and Okinawans. It is noteworthy that the rest of the Ainu gene pool was occupied by the paternal lineage (Y-haplogroup C-M217*) from North Asia including Sakhalin. Thus, the present findings suggest that the Ainu retain a certain degree of their own genetic uniqueness, while having higher genetic affinities with other regional populations in Japan and the Nivkhi among Asian populations.

大家可以看看文章第5頁的Y單倍群分布頻率表
庫頁島的尼夫赫人(Nivkhi)有28.6%的O-M175*
但這個O-M175*不包括O3-M122*及O1a-M119*
那究竟尼夫赫人的O-M175*是O2a,O2b,還是其他O支系?!

这个问题我很早就想知道,但是现在还是没有更多的资料。

这篇文献的数据引用自:
Three major lineages of Asian Y chromosomes-implications for the peopling of east and southeast Asia
而这篇又引用自Phylogenetic relationships of HTLV-I/STLV-I in the world.
没有进一步的研究。

其他的Nivkhi的Y的两组数据,也没有进一步的研究。

哎,有的时候科学进步得再快也是太慢

尼夫赫、尤卡吉尔这种对于东北亚民族源流有重要意义的族群,已经快没了
他们的Y取样都还不够,研究都还不够,语言考察也都还不够,但已经太晚了。

有时在想如果以后真的走研究族群的路,看到这些消逝应该跟银行家发现错失大好投资机会一样的抓狂吧
但投资机会这趟消失了下趟还会有,
这些没了就真的回不来了。

估计是日本的O1b2   P49
