Xinjiang,the most northwest provincial administrative area of China,was the area where the oriental people met the occidental.The populations in Xinjiang exhibit very high genetic diversity.Previous study revealed that the eastern Xinjiang populations of the Bronze Age were mixed by the Eastern and the Western Eurasians.However,few studies have been performed to reveal when the population admixture started and how far to the west it reached.In this paper,we studied 148 craniofacial traits of 18 skulls from the Bronze Age Liushui graveyard in Khotan(Keriya County) in the southwest of Xinjiang.Seventeen craniometrical parameters of the Khotan samples were then compared with those of other ancient samples from around Xinjiang using dendrogram cluster analysis,principal components analysis,and multidimensional scaling.The results indicated that population sample of Liushui graveyard was mixed by the Western and Eastern Eurasians with about 79% contribution from the east.Therefore,we demonstrated that population admixture between east and west Eurasia can be traced back to as early as 1000 BC in southwest Xinjiang.

Histone methylation is a kind of important epigenetic modification which occurs on the lysine residue or arginine residue of histone tails(Zhang and Reinberg,2001).It takes part in multiple biological processes,including gene expression,genomic stability,stem cell maturity,genetic imprinting,mitosis and development(Fischle et al.,2005).Abnormal histone methylation pattern
In the field of anthropology,the uniparentally inherited Y chromosome has long been used to trace the paternal lineage of the populations and to understand differences in migration and population genetics between males and females,with additional advantages of small effective population size,sufficient markers,and population-specific haplotype distribution(Jobling and Tyler-Smith,1995;Jin and Su,2000;Underhill et al.,2000).Many such population studies have rested on
The paternally inherited Y chromosome has been widely used in forensics for personal identification,in anthropology and population genetics to understand origin and migration of human populations,and also in medical and clinical studies(Wang and Li,2013;Wang et al.,2014).There are two kinds of extremely useful markers in Y chromosome,single nucleotide polymorphism(SNP)and short tandem repeats(STRs).

Dear Editor,Dispute between agriculture and initial population expansion in Neolithic Time has been in suspense for a long time.Agriculture first appeared in the Fertile Crescent of West Asia about 11–12 thousand years ago(kya),with domesticating few wild plant and animal species.There is also evidence of the cultivation of rice and millet in Yangtze and Yellow River Basins of China approximately 9 kya.During the subsequent times between 9 and 4 kya,agriculture
