ANTHRO 101 Lecture Notes - Lecture 23: East Los Angeles College, Multiregional Origin Of Modern Humans, Mutation Rate
Document Summary
H. erectus in africa spread out all over. H. erectus in africa evolved to h. sapiens then moved to other places. Distinct tool industry not associated with neanderthals. Oldest are found in africa (190 kya) Likely source of populations that moved into eurasia. H. sapiens moved into middle east and lived side by side with neanderthales for. Evolves rapidly (high mutation rate) and high copy number (easier to obtain from fossils) One small population from africa spread to europe and beyond. Oldest h. sapiens species eve" lived in africa 220-120 kya. All behavioural differences must be rooted in genetic differences. Information acquired by individual through some type of social learning. Activity of one animal indirectly increases the chance that other animals will learn on their own. Observational learning is not just a by-product of group living and being relatively intelligent. Allows humans to adapt to a wide variety of environments. Wild primates can attach meanings to arbitrary sounds.
