Modern human origins: recent out of africa vs multiregional (similarities, diff. s, data) [1] Out of africa (single recent origin): sapiens emerged in africa from previous hominids, then spread to asia (then europe, etc. ) and totally replaced hominids (e. g. neanderthals, other) who had left africa earlier. Hominids who had left africa much earlier evolved into h. sapiens in several different areas of the world some gene flow between regions (and not yet speciation by region) Out-of-africa (single recent origin) vs. multi regional: recent genetic studies do indicate a recent emergence of modern humans in africa (maybe. 100-200 kya): followed by spread to rest of world, couldn"t have been any interbreeding with the neanderthals, in recent years, it looked as though the single- recent-origin idea was completely right, and multi-regional was completely wrong. Social and behavioural differences between bonobos and chimpanzees [2] Chimps primarily males; bonobos primarily female intersexual dominance:
