    Highlights

    • Tianyuan/AR33K ancestry was widespread in northern East Asia before the LGM
    • The earliest northern East Asian appeared in the Amur region at the end of the LGM
    • The AR14K-related population is the closest East Asian source for Ancient Paleo-Siberians
    • EDAR V370A likely increased to high frequency after the LGM

    Summary

    Northern East Asia was inhabited by modern humans as early as 40 thousand years ago (ka), as demonstrated by the Tianyuan individual. Using genome-wide data obtained from 25 individuals dated to 33.6–3.4 ka from the Amur region, we show that Tianyuan-related ancestry was widespread in northern East Asia before the Last Glacial Maximum (LGM). At the close of the LGM stadial, the earliest northern East Asian appeared in the Amur region, and this population is basal to ancient northern East Asians. Human populations in the Amur region have maintained genetic continuity from 14 ka, and these early inhabitants represent the closest East Asian source known for Ancient Paleo-Siberians. We also observed that EDAR V370A was likely to have been elevated to high frequency after the LGM, suggesting the possible timing for its selection. This study provides a deep look into the population dynamics of northern East Asia.

    Awesome, I'm sure this will illuminate us more on the population dynamics of prehistoric East Asia.

    So, from my (very limited) reading of this study, AR33K is one of the oldest samples with East Asian-like ancestry (only Tianyuan is older), while Salkhit is a mix between this type of ancestry and the proto-ANE (West Eurasian) ancestry found in the Yana samples?

    Are these the oldest C2 and oldest D (assuming the DE is D) samples to date?

    Would be interesting to find out where it fits in the P tree. Could be a Q as well.

    Yes it seems correct. West eurasian arrived in Sakhalit via Yana probably.
    Or in other words: Proto West Eurasian dna was ANE like
