对塔里木盆地塔克拉玛干沙漠中部大河岩村58个样本的线粒体DNA（mtDNA）多态性进行了研究。在58个样本中，29个单倍型，属于18个不同的单倍型群进行了分析。几乎所有的mtDNA都属于欧亚大陆西部或东部的一个子集。大河沿人群中存在广泛的东欧亚血统，其中北方流行的单倍群呈现较高的频率。在现存的有限的欧亚西部谱系中，发现了中亚罕见的两个单倍型群U3和X2，这可能表明仅在塔里木盆地保存了来自近东和高加索地区的早期移民群体的残余。在塔里木盆地的现代和考古样本中发现的U3表明，移民发生在2,000年前，并指出该地区的人类连续性，至少有一个西方血统来自近东和高加索地区。美国物理人类学杂志142：558-564，2010。(C)2010 Wiley-Liss，Inc.
The mitochondrial DNA (mtDNA) polymorphisms of 58 samples from the Daheyan village located in the central Taklamakan Desert of the Tarim Basin were determined in this study. Among the 58 samples, 29 haplotypes belonging to 18 different haplogroups were analyzed. Almost all the mtDNAs belong to a subset of either the defined Western or Eastern Eurasian pool. Extensive Eastern Eurasian lineages exist in the Daheyan population in which Northern-prevalent haplogroups present higher frequencies. In the limited existing Western Eurasian lineages, two sub-haplogroups, U3 and X2, that are rare in Central Asia were found in this study, which may be indicative of the remnants of an early immigrant population from the Near East and Caucasus regions preserved only in the Tarim Basin. The presence of U3 in modern and archeological samples in the Tarim Basin suggests that the immigration took place earlier than 2,000 years ago and points to human continuity in this area, with at least one Western lineage originating from the Near East and Caucasus regions.
