Spread of Indo-European and Uralic speakers in ADMIXTURE


The following are updated files for unsupervised ADMIXTURE of most available ancient Eurasian samples with K=7. For reference, see PCA of ancient and modern Eurasian samples.

NOTE. For a precise interpretation of ancestry evolution, be sure to first check the posts on the expansion of “Steppe ancestry”, on the spread of Yamnaya ancestry with Indo-Europeans, and on the evolution of Corded Ware ancestry typical of modern Uralic populations.

Dzudzuana, Sidelkino, and the Caucasus contribution to the Pontic-Caspian steppe


It has been known for a long time that the Caucasus must have hosted many (at least partially) isolated populations, probably helped by geographical boundaries, setting it apart from open Eurasian areas.

David Reich writes in his book the following about India:

The genetic data told a clear story. Around a third of Indian groups experienced population bottlenecks as strong or stronger than the ones that occurred among Finns or Ashkenazi Jews. We later confirmed this finding in an even larger dataset that we collected working with Thangaraj: genetic data from more than 250 jati groups spread throughout India (…)
