现代蒙古的mt-DNA印记,2007年的最新研究,目前知道到了摘要,全文还没有看到。
大体的内容是说,该研究收集了蒙古3000以上的样本,其中包括21个部族或是族裔群体,样本数量和涵盖面积远高于之前的研究。最为典型的mt-DNA类型是C型,在东亚族群中是一个非常普遍的类型。但有接近40%的mt-DNA类型属于欧亚大陆西部起源,其中欧洲极为普遍的H约占7%。这样的研究结果似乎表明,至少母系方面来看,蒙古人在历史上吸收的来自中亚、西亚、欧洲等地的高加索人种血统应远高于传统的估计,而近40%的非东亚血统,似乎将蒙古人归入欧亚混血类型更为合适。
Mitochondrial DNA footprints in modern Mongolia.
Although Mongolia is one of the most sparsely populated countries in the world, it is located at a pivotal crossroad between the four corners of Asia (including the well-known Silk Road) and has been characterized throughout history by events that greatly added to its current cultural and ethnic diversity. Among these, perhaps one of the most significant happening was the ambitious expansion strategy employed by Mongolias most prominent personality, Genghis Khan, whose empire eventually stretched across all of modern-day China, a portion of modern Russia, Southern Asia, Eastern Europe and the Middle East. In 2007, through a well-planned collection effort, researchers at the Sorenson Molecular Genealogy Foundation and the National University of Mongolia were able to gather over 3,000 DNA samples, informed consents, and genealogical data throughout the country of Mongolia, including samples from 21 distinct tribal or ethnic populations. All the samples were sequenced for the three hypervariable segments of the mitochondrial DNA (mtDNA) control region to assess the genetic composition of modern Mongolia. The most common mtDNA haplotypes are typical of haplogroup C, which is frequent throughout Eastern Asia. However, nearly 40% of the observed mtDNA lineages are of Western Eurasian origin, including a significant frequency (~7%) of haplogroup H - the most common in Europe. The high prevalence of Western Eurasian lineages could be a remnant from Genghis Khans conquering efforts, trade and cultural exchanges along the Silk Route. To assess the extent of recent gene flow that could account for the elevated levels of Eurasian haplogroups within Mongolian populations, we have examined genealogical data of samples representative of Western Eurasian haplogroups.
