I've never understood where pre-humans like Peking Man, and Java Man, and Neanderthals come from - according to evolutionary science.
Does the same Out-of-Africa theory prevail?
Peking man went out for Chinese, Java man stopped for coffee and Neanderthals just Meander Malls.
The Out Of Africa Theory, Also known as Tarzan Goes Ape does not apply.
A slower clock (as in this article) is probably an outgrowth of the Replacement model, in which a master race of “anatomically modern” humans left Africa and completely wiped out all earlier forms (such as Homo Erectus, which is what Peking Man was) and Neandertal without mating. Both Replacement and Multiregionalism has some early species (generally, Homo Erectus) leave Africa and continue to develop in isolation from Africa and from one another. The two models differ in that, the Replacement model sez the isolated groups reached the point of genetic incompatibility with the other groups; the Multiregional model sez the egress from Africa led to isolated parallel development and eventually to the modern ethnic drifts we see today. The Multiregional model makes the most sense IMHO, and the Replacement model is just some kind of racist drivel. I’d also add that, since the continental shelf (which is now submerged) has been dry land for most of the past two million years, and the lower the altitude, the warmer conditions are (everything else being equal, such as at latitude for example), probably Africa and the rest of the Earth as we know it today was colonized from what are now the submerged areas.
