The Kura-Araxes-related ancestry signal in East Asia

Record summary

Ancient-genome studies from the Tarim Basin and wider Xinjiang region have shown that Bronze Age populations could possess distinctive local ancestry profiles while later communities reflected complex exchange across Central Eurasia. These studies matter for comparing migration, pastoralism, language spread and cultural transmission into East Asia. Genetic continuity or replacement varies by site and period, and material culture cannot be mapped directly onto a biological population. The interpretation of “Indo-European,” “Tocharian” or other labels requires linguistic and archaeological corroboration rather than genomic shorthand.
