While I agree that the Mongol Empire played a major role in the admixture of Caucasoids and Mongoloids, we have very clear evidence now that the two races had been mixing in Central Asia long before that time.

Genetic imprint of the Mongol: signal from phylogeographic analysis of mitochondrial DNA
Cheng B, Tang W, He L, Dong Y, Lu J, Lei Y, Yu H, Zhang J, Xiao C.
Abstract
Mitochondrial deoxyribonucleic acid (DNA) from 201 unrelated Mongolian individuals in the three different regions was analyzed. The Mongolians took the dominant East Asian-specific haplogroups, and some European-prevalent haplogroups were detected. The East Asians-specific haplogroups distributed from east to west in decreasing frequencies, and the European-specific haplogroups distributed conversely. These genetic data suggest that the Mongolian empire played an important role in the maternal genetic admixture across Mongolians and even Central Asian populations, whereas the Silk Road might have contributed little in the admixture between the East Asians and the Europeans.

ReplyDeleteSure, the Mongol Empire after all was only the penultimate epysode of Turkic expansion, that had been going on for more than one thousand years then. Probably Turkic expansion in earlier times was as decissive if not more in the genetic shaping of Central Asia as the brief Mongol epysode that was anyhow mostly manned by Turkic peoples.
What do they mean by "European" in these particular studies, I think they should make more clear.
ReplyDeleteThey should say "Caucasion", Central Asia was pretty much Indo-Iranian speakers before Turko-Mongol invasions.
ReplyDeleteEuropean is misleading. Although there were some folks even as far East as Xinjiang in China who were most likely from Europe they were not nearly the majority in Central Asia.
Well in hindsight, I suppose Europe ends at the Ural mountains in Russia. Although the end of Europe was considered Moscow once, and Turkey is sometimes considered European other times not.
ReplyDeleteAnyway its a small matter but I think they should use Caucasoid or at least be more specific and narrow it down some and give some ideas. As Europeans can be told apart from West/Central Asians or whatever you want to call them.

Now, here's a dilemma: are "Caucasoid" and "Mongoloid" genetic categories that are defined by belonging to particular haplogroups, or are they physical anthropological categories defined by a person's morphological attributes?
The reason I bring this up is because Mongols are anything but "Caucasoid" or "part-Caucasoid" in terms of their phenotypes. They are rather some of the most extreme "Mongoloids" on the face of the planet.

ReplyDeleteThe Caucasoid component in Mongolia itself is small and was introduced many generations ago, so it's not really detectible except for isolated traits in individuals.
In the paziriki's kurgans (mount Altai region, 1500- 800 B.C.) are buried caucasoids and mongolians togheter, it isn't a new.
ReplyDeleteNot new, at all.
ReplyDeleteSince ~50,000 years ago, when the first AMHs migrated out of Pakistan and Afghanistan into Europe (and pooled there to eventually migrate farther NE), there has never been a clear distinction between these two human groups.
The most extreme Mongolians are simply the groups that were isolated for the longest time from the originally much larger pre-caucasian population spanning much of the Indian and European continent.
