It's really not particularly anti-China imho, as indeed the West has its own brand of this in American Exceptionalism in general. We from smaller countries sometimes call this Big Country Syndrome.
It's true that China has a lot of affection for the Out of Asia theory of human origin, and to this day there are museums dedicated to the Peking Man that are at the very least heavily suggestive of this, or at least of China's population having a distinct origin.
Books and reams of sociology papers can and have been written about the relationship between CCP policy and the Peking Man and the CCPs difficulty with adjusting to today's generally preferred Out of Africa theory, and the effect on Chinese scientists working in anthropology. HN favorite Jimmy Maher (Digital/Analog Antiquarian) has a lovely line of free amateur history books including an excellent one on China that has a chapter on this:
I think it's a useful approach to contemporary Chinese identity. Nothing anti about that, any good-natured attempt to grok China would include this, just as no diatribe on America is complete without mentioning the 30-something % of Americans who state belief in some form of Creationism when polled.
I don't think less of China for containing a, shall we say, "patriotic" paleoanthropology community. Not any more than I think less of the US for the Book of Mormon being a thing. God knows we have these subcultures in Europe too.
But it is a thing and you need to be aware of it. A result from China which seems to support an out of China theory rather than an out of Africa theory, I am immediately suspicious of.
And you know, just because you and I don't bristle at the thought of descending from ancient Kenyans, lots of other people all over the world do. It's not just "regular" racists, also a lot of e.g. indigenous protected groups.
Given what we now know about backmigration and intermixing (particularly with Denisovans), it's really not coherent to say any "out of" theory is the Truth.
Sure, modern homo sapiens outside of Africa are all descendants of a founding group that left Africa, but they are also descendants of hominids who returned to Africa from elsewhere as well as local hominid populations that had left Africa far earlier (like Neanderthals and Denisovans).
Out of Africa has meaningful consequences even if people mixed back in. For example our closest evolutionary cousins should barring evidence to the contrary also tend to hail from Africa as well.
It’s that kind of reasoning that makes it important to try and be accurate here. Not a fact in isolation but everything else that it implies.
do Americans think higher about Europe just because ancestors of many of them came from there? Not happening.
I agree with you on the Sinophobia, but interest in the British royal family/British history generally and interest in Irish heritage are extremely common among groups of Americans. Most British visitors to the US can attest to how their accent is interpreted and affects treatment, in a positive sense, too.
