Document Summary
Significant because its was the first discovery. The earliest find was omo, ethiopoa 195 kya: high broad forehead, chin, narrow nose, globular vault, less robust post-cranial. Origin of modern h. sapiens hypotheses: single origin /complete replacement / out of africa (eve) hypothesis (stringer & andrews, 1988) Origin of modern humans in africa, with later complete replacement of all of other homo species (including neandertals) no inbreeding between neandertals and modern humans (haviland et al. , 2009) Based on primarily genetic evidence: morphological studies, genetic studies, mtdna mitochondrial dna; maternally inherited, y chromosomes, recent genetic profiling, nuclear dna, africa has the greatest level of mtdna diversity probably the home of the 1st modern. H. sapiens: genetic drift- founder effect, there will be greater genetic diversity in the founder population i. e. africa, approx. Several populations in africa, asian & europe evolving together from 100,000 40,000 ya. Looked for hybridization (haviland et al. , 2009) Based on: tool assemblages, fossil evidence, partial replacement hypothesis (brauer)
