欧亚人口史的再分析：人口亲缘关系的古代DNA证据
A Reanalysis of Eurasian Population History: Ancient DNA Evidence of Population Affinities
摘要：
线粒体高变区I的遗传数据，从亚洲两个地点，临淄在山东（中国北部）和额济纳旗在蒙古的古代人群，重新分析，以检测人口的亲和力。从总共51个现代人口的数据被用来产生距离的措施（FST的）的两个古老的人口。这些测试首先分析了区域层面的关系，然后汇编了最匹配的区域，以便与两个探针群体进行总体比较。再分析结果表明，额济纳旗和临淄两个群体的亲缘关系存在明显的差异。Egyin Gol人口作为一个整体似乎与东亚北部的现代人口密切相关。正如最初的分析所表明的那样，临淄种群似乎确实与西方有一些遗传上的亲缘关系，尽管最初的“欧洲样”的归属似乎是误导性的。这项研究表明，临淄人可能与早期伊朗人有关，伊朗人被认为在公元前第一个千年广泛分布于欧亚大陆中部和草原地区，尽管不能排除一些不同起源的人口之间的一些重要混合物。该研究还考察了序列长度对这种类型的遗传数据分析的影响，并对以往对临淄样本的研究结果进行了分析和解释。
英文摘要：
Mitochondrial hypervariable region I genetic data from ancient populations at two sites from Asia, Linzi in Shandong (northern China) and Egyin Gol in Mongolia, were reanalyzed to detect population affinities. Data from a total of 51 modern populations were used to generate distance measures (Fst's) to the two ancient populations. The tests first analyzed relationships at the regional level, and then compiled the top regional matches for an overall comparison to the two probe populations. The reanalysis showed that the Egyin Gol and Linzi populations have clear distinctions in genetic affinity. The Egyin Gol population as a whole appears to bear close affinities with modern populations of northern East Asia. The Linzi population does seem to have some genetic affinities with the West as suggested by the original analysis, though the original attribution of "European-like" seems to be misleading. This study suggests that the Linzi individuals are potentially related to early Iranians, who are thought to have been widespread in parts of Central Eurasia and the steppe regions in the first millennium BC, though some significant admixture between a number of populations of varying origin cannot be ruled out. The study also examines the effect of sequence length on this type of genetic data analysis and provides analysis and explanation for the results of previous studies on the Linzi sample as compared to this one.
