[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] Thanks. Some info from Chris Stringer, on why multiregionalism is still somewhat weak despite recent evidence of Neanderhal/archaic admix. http://www.sciencedirect.com/science/article/pii/S0169534714000470 QUOTE: "RAO is still the most appropriate model The big picture is that we are predominantly of recent African origin, and RAO is not just about the sources of our shared modern morphology and most of our genes; it is also about the genesis of our shared patterns of behaviour. Inferred behavioural gaps between Neanderthals and modern humans have certainly narrowed from recent research, but in my view they have not disappeared. I think that the pre-eminence of Africa in the story of modern human origins was primarily a question of its larger geographic and human population size, which gave greater opportunities for morphological and behavioural variations, and for innovations to develop and be conserved, rather than the result of a special evolutionary pathway. By contrast, genomic data suggest that the lineages of the Neanderthals and Denisovans had much greater demographic attrition [25], perhaps related to the challenges posed by the unstable climates of Eurasia, and this might well have inhibited their cultural as well as physical evolution [6]. ‘Modernity’ was not a package that had a single African origin in one time, place, and population, but was a composite whose elements appeared, and sometimes disappeared, at different times and places and then coalesced to assume the form we see in extant humans [6]. However, during the past 400 000 years, most of that assembly took place in Africa, which is why a recent African origin still represents the predominant (but not exclusive) mode of evolution for H. sapiens. Rather than saying ‘we are all multiregionalists trying to explain the out-of-Africa pattern’ [1], it would be more appropriate to say ‘we are all out-of-Africanists who accept some multiregional contributions’."
