Description:
The Tarim Basin in Xinjiang was a key crossroads for cultures and peoples across the Eurasian steppe, marking the eastern edge of western steppe expansion. Despite its importance, the prehistoric genetic record remains underexplored. We present genome-wide data from 24 individuals from the western Tarim Basin during the Bronze and Iron Ages. Bronze Age populations inherited most of their ancestry from Andronovo-related pastoralists, mixing with BMAC farmers and local groups. Interestingly, we found an Iron Age individual with minimal genetic influence from steppe populations, suggesting continuity between BMAC and indigenous Tarim ancestors, underscoring a lasting indigenous genetic legacy for over 3,000 years.
