Hmmm..... Quick Question, even though I am new here, I was wondering, who exactly are the Ainu/Jomon? Were they descendants of a group of Africans (proto-negroid or negroid) that settled in South Asia and then traveled to Japan?

Second, about the features of Japanese folks. I understand some (not all) have Caucasoid features. But how much of the features and how frequent?

Third, I know this is off topic, but in regards to China (and well Japan too), were the first dynasties/ruling parties/governments Black?
