Some historians believe that the H. Sapiens traveled out of Africa and began populating the areas where the Neanderthals were living. Eventually the H. Sapiens, more flexible to the changing climates and smarter, drove the Neanderthals, specialists like the A. Bosei, to extinction.

Other historians believe that when the H. Sapiens moved out of Africa, they traveled in smaller groups, as opposed to the huge migration mentioned in the other theory. H. Sapiens and H. Neanderthalensis, very similar species, were structured so similarly that they could successfully interbreed. Over time, the two groups melded into one and the individual group of Homo Neanderthalensis ceased to exist.
