Abstract
Situated at over 5,000 meters above sea level in the Himalayan Mountains, Roopkund Lake is home to the scattered skeletal remains of several hundred individuals of unknown origin. We report genome-wide ancient DNA for 38 skeletons from Roopkund Lake, and find that they cluster into three distinct groups. A group of 23 individuals have ancestry that falls within the range of variation of present-day South Asians. A further 14 have ancestry typical of the eastern Mediterranean. We also identify one individual with Southeast Asian-related ancestry. Radiocarbon dating indicates that these remains were not deposited simultaneously. Instead, all of the individuals with South Asian-related ancestry date to ~800 CE (but with evidence of being deposited in more than one event), while all other individuals date to ~1800 CE. These differences are also reflected in stable isotope measurements, which reveal a distinct dietary profile for the two main groups.

路普康湖有200多具骨骸,位于喜马拉雅山区。

     非常有意思的y频度,A组明显是印度河谷文明类型,B组似乎与北部草原人群有关,不过未见雅利安人最常见的R1a1a1a,很有意思,呵呵。 至于这个R1b1a,应该也不是印欧常见型(应该是call了下游没有响应)。  C组应该是东亚类型,可能与阿萨姆邦移民有关,也可能是东亚或中南半岛的朝圣者墓地(没看原文,瞎猜,呵呵)

分析了一个B组(接近地中海人群)的样本I3345,分型结果为R1a1a1b1a2b3a4a2b-Y42057

R-M12335 Y42057 formed 1800 ybp, TMRCA 1450 ybpinfo,与乌克兰和克罗地亚样本仅1450年的共祖关系。
