Document Summary
Hominin evolution, neanderthal genome, denisova genome and gene flow. Proposes that modern humans dispersed out of africa and replaced populations of h. erectus and neanderthals without interbreeding. Proposes that evolution of modern humans has been occurring since early humans (h. erectus) left africa 2 mullion years ago. Continuous exchange of genes among population in different regions united this species as it evolved into modern humans. Supported by primitive characteristics in some modern races: shovel shaped incisors in asians, prognathic face and large cheeks in australian aboriginals. But these features could be convergently evolved, or simply a polymorphic ancestral feature. Present in western eurasia from approximately 127,000 years ago. Lived in europe, western asia and southern siberia. Anatomically modern humans were living in these areas at this time from approximately 80,000 years ago. Large cranial capacity around 1,400 cc, larger than modern humans. Mostly meat eaters but evidence of plant material has also been recovered on fossil molars.
