Document Summary
Anatomically modern human migration out of africa - chris stringer and peter andrews. Anatomically modern humans did not interact or interbreed with hominins that lived alongside them. Multiregional - evolved alongside one another in different areas of the world - milford. Contradicts what we already know about genetic relatedness. Partial replacement model mostly out of africa - partial replacement of hominins. Relatively small pops gave rise to all modern people in and out of africa. Individuals in african pops more genetically variable than the rest of the world (gene flow) Non african pops closely related) founder effect. Dates for upper paleolithic burials and tool styles fit a replacement model over a multiregional model. Earliest anatomically modern human fossils in africa - omo 1 (195 kya), herto (160-154 kya) Same strata - same context - they were the same time period. Omo 2 - retained ancestral traits, perhaps homo heidelbergensis/homo. Better source of info bc its more complete.
