But using the latest fossil findings, Martinón-Torres and colleagues were able to examine more than 5,000 teeth from two-million-year-old Australopithecus and Homo skeletons from Africa, Asia, and Europe.

So, it appears this deals with ancestors, and is not really relevant to the out of Africa theory as to Homo Sapiens.

Well put. The multiregionalist view is that humans came from Africa, very long ago, then diversified; the Replacement hypothesis is that something called anatomically modern humans originated only in Africa, sat there for a long while, then about 50,000 years ago exploded across the globe, not stopping until reaching Tierra del Fuego perhaps 10,000 years ago. “Out of Africa” is now a vague term which is often used as a prop for Replacement.
