DEI does exist at universities, but the idea that human evolutionary biologists let their research be directed by DEI concerns is ridiculous.

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.
