回族起源的DNA证据

应用现代DNA分析技术,研究回族的起源、迁徙、融合、演变,探讨回族与其他民族之间的关系及有关发展规律,应是回族学研究的一个值得重视的方面。本文利用本实验室积累,综合国内外其他族群基因资料,以群体角度从DNA水平探讨了回族的起源、迁徙、演化等问题,证实了以往大多数人类学调查的结果,即回族与北方民族之间有相当大的融合。并且明确了回族中有较大比例的高加索人种的混杂程度,而这种基因流动应该主要与唐宋时期西域商贾、使者留居和蒙元时期蒙古人西征有密切关系,为传统的回族学研究提供了新视角。

The DNA Evidence of the Origin of Hui

The origin and development of Hui ethnic groups is a complicated problem. However,DNA analysis could provide a new method to resolve it with recent advances of genomics. In the present work ,the phylogenetic relationship revealed by data of D13S317 and linguistic studies. Furthermore, the Caucasian associated allele was tested in several of the the minorities living in Northwest China. The amounts of Caucasian admixture have been estimated beyond 25% only in Hui and Dongxiang. The presence of Caucasian admixture was attributed to the Caucasians living in Central Asia throughout the peaceful immigration from the Tang Dynasty to Song Dynasty and military activities of Mongolian army during the initial Mongolian Yuan Dynasty. From these data, the paper discussed the possible revelations of the origin of Hui and Dongxiang enthnic group.
