内蒙古和林格尔东周时期古代人群的分子遗传学分析

对10个古代个体的线粒体DNA高可变Ⅰ区进行了扩增和测序. 基于和林格尔古代人群与现今相关欧亚人群的mtDNA序列， 进行了系统发育分析和多维尺度分析. 研究结果表明, 和林格尔古代人群在母系遗传上与现在北亚人群的亲缘关系最近. 结合考古学、 人类学以及分子生物学的研究， 推断这个古代人群是从蒙古高原以及外贝加尔地区南下迁移至今天的内蒙古和林格尔地区的游牧人.

Molecular Genetic Analysis of Dongzhou-period Ancient Human in Helingeer in Inner Mongolia

In order to investigate the genetic structure of Dongzhou period ancient population in Helingeer in Inner Mongolia and relationships between the ancient population and related extant populations as well as to trace the possible origin at a molecular level, mtDNA hypervariable region Ⅰ (HVR Ⅰ) of 10 ancient individuals was amplified and sequenced. Phylogenetic analysis and multidimensional scaling analysis were also performed based on the mtDNA data of the ancient population and the related Eurasian populations.The results show that the ancient population is closer to the populations from Northern Asian than the other compared populations in matrilineal lineage. Combining the research results of archaeology and anthropology as well as molecular biology, we can conclude that they are nomad who migrated from Mongolian altiplano and cisBaikal area to Helingeer in Inner Mongolia.
