New paleogenomic research published in Cell has analyzed the remains of foragers from the Tarim Basin dating to 10,000 BCE. The study identifies a previously unknown 'migration pulse' from the Iranian Plateau that occurred shortly after the Younger Dryas climatic event. This genetic influx suggests that the deep ancestors of the region's populations were part of a widespread movement of post-glacial groups who brought early proto-agricultural knowledge and stone-tool technologies into Central Asia.
The data reveals that these early Tarim inhabitants possessed genetic markers for high-altitude adaptation and cold-weather metabolism, which allowed them to navigate the mountain passes of the Pamirs. This study fundamentally alters the understanding of human dispersal in Eurasia, showing that the desert basins of East Asia were connected to the Near East much earlier than the establishment of the formal Silk Road trade networks.
