BIOL 123 Lecture Notes - Lecture 16: Homo Erectus, Multiregional Origin Of Modern Humans, Mitochondrial Eve
Document Summary
People who think archaic homo sapiens are the same speices as us. Amhs evolved from regional archaic homo sapiens. Gene flow maintained a single spcies since archaic homo sapiens (or homo. But held together by natural selection and some gene flow. Homo erectus, archaic homo sapiens, and amhs are just convenient labels. Initial branching but all continue to evolve together. East asia: high cheekbones, shovel shaped incisors. Europe: occipital buns, low forehead, prominent brow ridge. Humans evolved from africa and there is no interconnection between them and. All amha descended from a single population in africa. Appearance of amhs was a speciation event. Eventually all archaic homo sapiens are replaced, including neanderthals. Neanderthals are in no way ancestral to humans. Earliest anatomically modern fossisl are from africa by a long shot. Matrilineal most recent common ancestor (mrca) of all currently living. Most recent woman from whom all living humans today descended on their mothers side.
