Population dynamics in Iron Age Xinjiang inferred from ancient genomes of the Zhagunluke site

2023-12-01
Description:
Zhagunluke culture, as one of the Iron Age cultures in southern Xinjiang, was the representative of the ancient Qiemo kingdom that showed diverse cultural elements and the coexistence of agriculture and livestock farming. However, the genetic structure and formation of ancient Qiemo people were unclear. Here, we reported the ancient genomes of two individuals from Zhagunluke No.1 cemetery. Combined with previously published data, we observed that most Zhagunluke samples showed genetic admixtures between East and West Eurasians with varying proportions of ancestry. However, we also found a genetic outlier with dominant millet farmers-related ancestry from the Yellow River or the West Liao River basins. The genetic substructure of the Zhagunluke population demonstrated multi-way demographic interactions in Iron Age southern Xinjiang with populations from the surrounding areas of Western Steppe, Central Asia and East Asia.
