afro-centric has always been crap; this piece of the language links is just another piece of the picture. There are four traditional racial types and it has never made sense that one genotype marched out of africa and morphed into three other types over what is in evolutionary time a few weeks. Australoids are distinct from Mongoloids,distinct from Negroids, distinct from Caucasoids. All are human but what triggered the many from one type?

Exactly. I've never bought into the politically correct "out of Africa" Lysenkoism. The human origin ball of twine is very far from unwound. There are huge areas of the globe (Asia mainly) that are virtually unexamined from an anthropological point of view. But publicity-seeking "scientists" are quick to claim they have the "final answer."

Thanks! It's refreshing to find someone who is unafraid of stating the obvious in this politically correct world.

Instinctively, that argument against makes sense; and it is satisfying emotionally.

OTOH, in a hugely shorter time span, we've demonstrably gone from

There wasn’t an event that triggered the evolution of humans Into the four main groups (and countless minor groups). Genetic drift over time, with geographic separation between the groups, actually explains the diversity pretty well.
