Document Summary
Recent african origins (rao) versus multiregional evolution (mre) Implications for understanding modern humans and the concept of race . So not find evidence of this massacre. Africans brought disease into europe and asia. Speciation event had occurred in africa prior to departure. Multiregional evolution (mre: anatomically modern h. sapiens should appear contemporaneously in the old world, transitional populations will appear regionally throughout the. Old world: h. erectus and h. sapiens are both h. sapiens - neanderthals are part of modern populations, genetic variation within each human group should be about the same. Most recent common ancestor of our mtdna lineage (maternal ancestor) Deepest lineages are in africa, haplogroup l. So our mitochondrial ancestors are in africa. The number of ancestors in previous generations 2t t= number of generations. Reality in the past there is some overlap. Over 200x the actual amount of people on earth. Probability that any two sequences will coalesce in any given generation.
