@Olivier5,
H.s.s. and h.n. were both present in Europe and in southwest Asia (what we call the middle east) thousands of years before the disappearance of h.n. In fact, the current majority opinion is that both h.s.s. and h.n. reached northern Eurasia at least 40,000 ybp, and possibly earlier. H.n. is believed to have died out between 35,000 ybp and 30,000 ybp--which is thousands of years
after both species arrived in Europe (although it is not really appropriate to call h.n. and h.s.s. different species as they are known to have successfully interbred). If your bullshit were correct, the fact that it took Cro Magnon thousands of years to wipe our h.n. makes them look pretty damned incompetent. But what is really hilarious here, is that you say: "The evidence is . . . " Oh yeah? Can you provide a source for that evidence? Have you got a link for that?
David Reich of Harvard University along with geneticists from Oxford University produced a genetic map of human migration in Eurasia in 2011. Additionally, Reich's research team have found a good deal of evidence that h.n. interbred with Denisovans as well as h.s.s. (it is not even clear that Denisovans are distinct from h.s.s., and remains of h.s.s. and Denisovan "hybrids" dating back 90,000 ybp were found about a decade ago). The most recent discovery has set the world of human paleo-genetic studies on its ear, as a teen-aged female has been discovered in a cave in Siberia with about 50-50 h.n. and Denisovan genetic material. I frankly don't believe you know a goddamned thing about this subject. I'll just remind myself of your comment at Fluther that you come online because you like to argue--to which I would add that you never seem to have anything to back up your bullshit.
