Hmmm, well, Ok. My understanding of the whole thing is; out of Africa’s primordial soup came humankind. Then it developed into some sort of upright humanoid. All this still in Africa. Then supposedly through some ‘magic’ they developed into three sub-races who counter mingled with each other. Neanderthals became a separate ‘whatever’ since there are no further links to them because none of us are dragging our knuckles on the ground. So, if non-African races (whoever or whatever they were) interbred with Neanderthals (whoever or wherever they came from since they were only found in the mountains of France/Switzerland/area) where did the basic race groups come from since none contain any Neanderthal genes or ‘looks’. They, the Neanderthals died out. What were they before and what became of the gene?
Neanderthals were not knuckle-draggers. They walked upright like you and I do. Take a look here, and at the reconstruction here. If the Neanderthals looked like the National Geographic reconstruction, then if you brought one up to current time and dressed him in modern clothes, he could sit next to you on the bus and you would not give him a second look.
