Non-african modern humans share 1-4% of dna with. Buried their dead- evidence from about 50,000 years ago in france, la chapelle-aux- Cared for elderly, injured, and sick- lots of examples of burials with healed and broken bones. From 60,000 years ago; kebara cave in israel- stone tools. Origins and dispersal of anatomically modern homo sapiens. When did anatomically modern h. sapiens first appear: modern humans evolve and disperse throughout africa ~200,000 y. a, ~50,000 y. a one african population migrated to eurasia and europe replaced local populations (no gene flow) How did the dispersal of h. sapiens take place: h. erectus disperses early from africa, ~1. 25mya, populations linked by gene flow, single hominoid species since then, modern populations arose from ancient, local lineages.
