Document Summary

Chapter 10: evolution and nature of modern humanity. modern looking people first appeared 195 000 to 165 000 ya; showing modern traits as far back as. claims that h. sapiens rose in africa about 2 mya; when we see anatomical and behavioural characteristics that define out type of primate). Members of this species (h. erectus) spread throughout the old world, evolving genetic and phenotypic regional difference. Degree of species mobility resulted in sufficient gene flow to maintain a single species resulting in no speciation. Successful adaptive features were dispersed across the species through gene flow. homo sapiens were not a separate species, they did not rise in the recent past, and that it did not spread and replace other species of homo. If this model is correct then there should be no evidence that modern h. sapiens is a separate species from premodern groups.
