No it's mainly coming from China. There are several scientists in China which are trying to use theories like this to argue Chinese descendants are a separate (and some argue superior) species.

Isn't most science like this coming out of the west generally?

Most people outside of China. Not just "the West".

I'll take your word for it. Still doesn't address the logical fallacy in the first place.

Most people meaning most people who have an informed opinion, because the evidence (archaeological, genetic, etc.) is so ridiculously in favor of the out of Africa theory. You have to be at the denial level of “evolution is just a theory” to think otherwise.
