Document Summary
Homo heidelbergensis evolved into homo sapiens in africa. Page 303: anatomically modern humans evolve in africa between 200 and 100 kya. Culture either gradually evolved or suddenly changed at 60 kya: migrated from africa about 60 kya. Founding population of 10,000 adults: migration along the southern coast of asia. Interactions and a small amount of interbreeding with neanderthals. Multiple species were present outside of africa 250-50 kya, including h. sapiens. Moreover, h. heidelbergensis and h. neanderthalis were outside of africa when h. sapiens evolved. Different hypotheses from different researchers: none completely agree with figure 10. 36. Argues for a single global species of h. sapiens large population with much interbreeding. First, let s see what modern humans are for each, then review the evidence. The origin and spread of modern humans: fossils. 100,000 200,000 years old: africa, omo kibish at 190,000, herto at 160,000. Supports african origin, migration to asia, then europe.
