Razib Khan's Unsupervised Learning

May 14, 2024

On this episode of Unsupervised Learning Razib talks about the April 2024 preprint The Genetic Origin of the Indo-Europeans. This blockbuster publication introduces nearly 300 new ancient DNA samples, uncovers the origins of the Yamnaya, and delves into how they transformed the genetic and cultural landscape of Eurasia ~5,000 years ago.

Razib addresses:

  • The now-identified ancestors of the Yamnaya

  • The genetic landscape between the Dnieper, Volga and Caucasus before the Yamnaya and that region’s numerous distinct populations

  • When the Yamnaya came into being as a distinct genetic-cultural cluster (after 4000 BC)

  • The relationship of the Yamnaya to the Anatolian Hittites and the newly refined idea of an Indo-Anatolian (as opposed to Indo-European) language family

  • The region where proto-Indo-Anatolian languages likely flourished, and why they disappeared

  • The population-genetic landscape of clines vs. clusters in human genetic structure over historical time
