Abstract: To detect possible gene flow from western Eurasia, European racial characters are examined and the mean rates of occurrence are calculated for each of 11 cranial samples from China. The results show that: 1)western genes appeared in Chinese populations as early as 2000- 3000 years BP; 2)it is through the Xinjaing region that the western gene flow spread eastward and into central China; 3) archaeological and morphological evidence shows that the racial advance limited to eastern Xinjiang and western Gansu before the Qin and Han Dynasty. In contrast, this study indicates that there were no such limitations of geography and dynasty in the movement of European racial characters.

Key words: Racial characters; West gene
