Connecting with the Turpan Basin, the Eurasia steppe and the Gansu Corridor, the Eastern region of Xinjiang has played a significant role in the history of human migration, cultural developments, and communications between the East and the West. The population origin, migration and integration of this region has attracted extensive interest among scientists.
In order to research the population origin and movement of the Eastern Xinjiang, genetic polymorphisms studies of the Hami population were conducted. The Hami site is located in the East of Tian-Moutain in Xinjiang, dating back to the Bronze-early Iron age. Archaeological studies showed that the culture of the Hami site possessed features from both the East and the West. Ancient mtDNA analysis showed that A, C, D, F, G, Z and M7 of the Eastern maternal lines, and W, U2e, U4, and U5aof the Western maternal lines were identified. Tajimas’D test and mismatch distribution analysis show that the Hami population had experienced population expasion in recent time. The demographic analysis of haplogroups suggests that the populations of the Northwest China, Sebiria and the Central Asia have contributed to the mtDNA gene pool of the Hami population.
Our study reveals the genetic structure of the early popultion in the Eastern Xinjiang, and its relationships with other Eurasian populations. The results will provide valuable genetic information to further explore of the population origin and migration of Xinjiang and the Central Asia.
