Kılınç, G. M. et al. Human population dynamics and Yersinia pestis in ancient northeast Asia. Science Advances 7, eabc4587 (2021) doi:10.1126/sciadv.abc4587
We present genome-wide data from 40 individuals dating to c.16,900 to 550 years ago in northeast Asia. We describe hitherto unknown gene flow and admixture events in the region, revealing a complex population history. While populations east of Lake Baikal remained relatively stable from the Mesolithic to the Bronze Age, those from Yakutia and west of Lake Baikal witnessed major population transformations, from the Late Upper Paleolithic to the Neolithic, and during the Bronze Age, respectively. We further locate the Asian ancestors of Paleo-Inuits, using direct genetic evidence. Last, we report the most northeastern ancient occurrence of the plague-related bacterium, Yersinia pestis. Our findings indicate the highly connected and dynamic nature of northeast Asia populations throughout the Holocene.
After Yu et al. 2020, this is the second Bronze Age plague genome from Lake Baikal. Since this paper was probably submitted before the publication of Yu et al. 2020, this is not discussed here, and the claim that they report the most northeastern Y. pestis genome does not hold true. Unfortunately, the coverage of their genome is extremely low, so it could not be phylogenetically assessed.
