The last guy almost got it right in that most people, excluding most sub-Saharan Africans have a minuscule amount of neanderthal DNA. Between 1 and 2 percent. We used to think it was as much as 4, but it's been revised down with newer studies.
But I like his decision to rename our species "Sapien Neanderthalensis" (except black people) based on that.
Oh I guarantee it's a serious comment.
