Nah they don't. Anti-"DEI" billionaires like Elon Musk are free to likewise fund research or create "free speech" universities if they so choose. But they choose not to.
You sound like you're pushing a theory that anthropology is biased, what do you have to back that claim up?
It does not allow anyone that questions it to be called racist per se, but the questioning itself is just unsubstantiated and vague.
This comment chain started with someone claiming contradictory evidence is not considered; where is this contradictory evidence? I mean sure, if there is an effective suppression campaign going on then said evidence would be gone, but surely there'd be whistleblowers and first hand accounts of scientific oppression and the like? If not, it's more effective than e.g. North Korea's regime in keeping information hidden, and like the moon landings, hundreds of thousands of people would be complicit. Which would be really interesting.
The whole out-of-Africa vs. multiregional debate played out over many years between different research groups, and what ultimately settled it was DNA evidence that heavily favored the out-of-Africa hypothesis.
With more data and more findings, it's become clear that modern humans do have some DNA from different populations outside Africa, but out of Africa is still basically correct.
