@Olivier5,
I find that all very unconvincing, and it constitutes speculation, not evidence. The Israelis have a quite well-developed archaeological site where h.n. arrived after h.s.s., and where the two lived side-by-side with no evidence of violence for many centuries. The most prominent feature of the excavation was the examination of the middens. The h.n. middens contained predominantly the detritus of hunting, and much less evidence of forage foods than was the case with the h.s.s. middens. Additionally, the h.s.s. middens contained evidence of the use of fish and shellfish, which was completely absent from the h.n. middens. I think it far more likely that h.n. was unable to effectively compete for resources in the longterm, while the diversity of food sources, especially forage foods, used by h.s.s. got them more surely through the lean times. If the evidence which has been found is correct, h.n. went extinct as the last phase of the last ice age closed in.
Once again, you offer speculation, not evidence.
