They definitely spread some good will!
BTW, they'd only been back in Yakutia about 200 years. They'd had an extended stay in India that lasted at least 500 years. As conquerors there they had their way with the local girls and brought "large breasts" into the tribe to stay. These later on showed up in certain Korean families AND, voila, among certain Japanese families.
In an earlier time this particular bunch, once again in Yakutia (their on again/off again homeland grazing range) took trips to the Arctic ~ you can trace the Eskimos to some of their clans. They also took trips to the Americas. Na Dene people may well be pretty much Yakuts.
Worth noting ~ Buddha was a Yakuts (or Sakha as they are also known).
More recently DNA studies have pretty much linked them to a degree with the Sa'ami ~ thus explaining why the Sa'ami and the Eskimos have some of the same genetic differences that make it possible for them to live in the Arctic.
It is quite easy to laugh at the Korean and Japanese claims to homogeneity!
Let me do so: Ha ha ha ha ha ha ha ha!
We Polish are completely Polish! Never had any problems with invaders! (sarcasm).
Yakut that out! ;’)
Any DNA evidence to corroborate that? I think it’s too far-fetched.
