The Tarim Basin of Xinjiang, China, with its fertile rim of oases, was home to a homogeneous population living in two settlements about 600 kilometers apart. It is likely that marriage partners were exchanged between the settlements.
The physical features of the Tarim mummies initially suggested that they were Indo-European migrants. Many had high cheekbones and red or blonde hair. However, DNA analysis revealed they were a genetically isolated population descended from Ancient North Eurasians (ANE) who had not mixed with other groups for thousands of years.
Investigation of their genomic origins found that this isolated population practiced endogamy. Scientists analyzed genome-wide data from thirteen of the earliest known Tarim Basin mummies, dating to between 2,100 and 1,700 B.C., together with five individuals dating to 3,000 - 2,800 B.C. in the neighboring Dzungarian Basin. This first genomic study of prehistoric populations in the Xinjiang Uyghur Region included the earliest yet discovered human remains from the region. The researchers found that the Tarim Basin mummies were direct descendants of a once widespread Pleistocene population that had largely disappeared by the end of the last Ice Age.
Hundreds of mummified bodies have been found in the Tarim Basin. The oldest mummified remains date to about 2000 B.C., the time of Abraham. They are well preserved due to the dry conditions of the Taklamakan Desert. The process of desiccation dramatically slowed decomposition of the bodies and clothing. Some of the burial sites held boat-shaped coffins covered with cattle hides, woven textiles, cheese, grains, and death masks.
“Despite being genetically isolated, the Bronze Age peoples of the Tarim Basin were remarkably culturally cosmopolitan – they built their cuisine around wheat and dairy from the West Asia, millet from East Asia, and medicinal plants like Ephedra from Central Asia,” says Christina Warinner, a senior author of the study, a professor of Anthropology at Harvard University, and a research group leader at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
