 The Multiregional Hypothesis argues that our earliest hominid ancestors radiated out from Africa and Homo sapiens evolved from several different groups of Homo erectus in several places throughout the world. I remember reading about this theory way back when I was a student in the last 80's. Does it hold any scientific validity today or has the question finally been settled? That modern Homo sapiens emerged out of Africa.

Africa is the best bet for the earliest. The origin in Africa is probably unbeatable. With the plethora of prehuman predecessors in it, Africa is the best guess in the ongoing nearly settled  discussions.

I understand that the greatest degree of genetic diversity in human populations today is found in Africa.
That suggests that humans evolved in Africa, and most of them never left.

 Excellent point.

 From what I've read on the multiple regional hypothesis there is no longer any real argument coming from scientists that homo sapiens did not emerge out of Africa. The only counter argument they may now have is the interbreeding of homo sapiens and archaic humans outside the African continent. The actual impact that had on the evolution of those outside of Africa is something worth looking into.
