I think some Mongolians might be thinking of pieces of land in Inner Mongolia.
If that is the case then why aren't more Jomon, Mongols and Turks trying to get a piece of China. With this piece of info they could reasonably invoke some native territorial rights.
For Turks... Xinjiang is too far from them, separated by those "stans" that are dominated by Turkic states.
I think we have to find the study again and read carefully...
I have heard that the O group had its presence cornered in Yunnan before it began its divergence and became associated with basically 3 groups: A Yangtze river basin group which would include the subgroups of Miao, Baiyue, Austroasiatic, a Tibeto-Burman group, and a Yellow river Huaxia group. I'm not sure about the whole second migration from Xinjiang to Northern China.
That is where I am wondering: whether the migrations take a lot of females with them, or not.
He's talking about the way Mongolians moving into Han territory as a group would have carried their women along with them and so the northern Han would have a percentage showing the Mongolian side of things while this would be far less so more south you go because there would be less Mongolians taking residence. Southern Han while not pure would not in significant terms have a percentage showing the Mongolian side of things but rather it would all come across as O-marker if you don't estrange the females away from their O-marker carrying fathers.
I do know that Kalmyks move whole families not only females, and as a result they are still mostly "Mongoloid" now.
But, if their O-yDNA are similar, why not also mtDNA? I don't think it would be "female-dominated" migration.
Those were probably only distantly related to Mongoloids.
Oops, sorry, wrong writing. It should be C and D as the proto-Asian.
Those that are closer to the ancestors of O (I think things like F, K) can also be found in Middle East.
Sorry again. I mean the ancestor of O yDNA, Haplogroup MNOPS.
They are close, however N and O are considerably closer to each other than say, A or B.
yDNA NO and R has close relationship compare with any other yDNA group.
I thought it might be referring to immune genes instead of physical characteristics?
Most of Northern Chinese live near Turkic border, so does other O yDNA group of people who live in SE Asia who live near Austronesian people. It's well-known that Northern Chinese has some physical similarity with the Turkic people, while SE Asian has some similarity with Austronesian people like Australia Aborigine and Papuan.
Anyway, the point was that it's not easy to tell whether South Chinese or North Chinese are purer.
