Sheep have been one of the most important groups of animals since ancient times.However,the knowl-edge of their migration routes and genetic relationships is still poorly understood.To investigate sheep matemal migration histories alongside Eurasian communications routes,in this study,we obtain mito-chondrial genomes(mitogenomes)from 17 sheep remains in 6 Chinese sites and 1 Uzbekistan site dated 4429-3100 years before present(BP).By obtaining the mitogenomes from the sheep(4429-3556 BP)found in the Tongtian Cave site in Xinjiang,Altai region of northwest China,our results support the emer-gence of haplogroup C sheep in Xinjiang as early as 4429-3556 BP.The combined phylogenetic analyses with extant ancient and modem sheep mitogenomes suggest that the Uzbekistan-Altai region may have been a migration hub for early sheep in eastern Asia.At least two migration events have taken place for sheep crossing Eurasia to China,one passing by Uzbekistan and Northwest China to the middle and lower reaches of the Yellow River at approximately 4000 BP and another following the Altai region to middle Inner Mongolia from 4429 BP to 2500 BP.Overall,this study provides further evidence for early sheep utilization and migration patterns in Eastern Asia.
