Population Structure in Mongolia from a Mitochondrial DNA Perspective.
Mongolia has experienced a complex series of demographic movements over the past 10-20 millennia that have shaped the patterns of its modern human genetic variation. However, modern populations in Mongolia have not been extensively studied for DNA diversity, nor has the genetic contribution of Mongolians to the gene pools of contemporary populations in Southeast Asia and Oceania been fully resolved. Archaeological evidence from as early as the late Neolithic suggests the presence of both West and East Eurasian cultures in this region. Later demographic movements involving the emergence of the Mongolian and later Manchu Empires have further convoluted Mongolias population structure. To clarify the complex population history of Mongolia, we analyzed variation in the mtDNAs of 190 individuals from several Mongolian ethnic groups, including the Uriankhai, Zakhchin, Derbet, Khoton and Khalkha. We screened all samples for phylogenetically informative coding region SNPs and sequenced HVSI to assess control region variation in them. Our data suggest that the mtDNA diversity present in our population is consistent with the general pattern of variation observed in East Asia, with the most frequent haplogroups being C, D and G. Haplogroup variation in Mongolian ethnic groups reveals considerable maternal diversity with a predominance of basal M types. Interestingly, the Mongolians also possessed West Eurasian haplogroups, such as H, J and K, which are not commonly observed in East Asia, even at low frequencies. The main ethnic group in Mongolia, the Khalkha, was highly variable with respect to mtDNA haplotypes in comparison with the other ethnic groups, and clearly distinct from the Khoton and Zakhchin, as evidenced by distance measures. Overall, these data provide insights into the origins and affinities of these populations, their relationships with East Asian groups and neighboring Turkic speaking groups, including indigenous Altaians, and their possible role in the peopling of the Americas.
http://dienekes.blogspot.com/2008/09/ashg-...-abstracts.htmlI find this interesting because I think Japanese have more "Caucasian" features than Mongols, but Mongols clearly share more overlapping ancestry (at least on the female side) with Western Eurasian people (from the Middle East into Europe).
My theory is that this is not recent, but could be pre-Mongol expansion? The Eurasian steppe was full of horseback nomads long before that and there was obviously a Slavic, Indo-Persian speaking, and Turkic speaking population with the Mongols on the far Eastside of this cline. Could this just be a result of normal gene flow between nomadic people? I could imagine them trading women like horse, sheep, etc for good they could not make themselves. The Chinese also recorded people who appeared to be Western Eurasian in the current area of Xinjiang, as early as the 2nd century BCE. Xinjing borders Mongolia and although I do not know the topography of the land various turko-mongol groups have been in an out of the area since that time period (and maybe before). I wish there was some talk of the frequency of these haplogroups.
Anyway...some of these people look Korean or Chinese to me.
There are some that look strange, obviously the brown and blonds look strange...there are Korean kids and Japanese kids and adults with brown hair, natural, I've seen it...my sister in law had brown hair when she was a kid and very light brown eyes, her eyes are still very light like her father, but the bone structure of her face looks very "Mongoloid".
I'm interested to hear opinions...
