Document Summary

All have cut marks made by other humans. Mostly modern looking features, but still retain some ancestral traits. Suggests that modern humans evolved across the continent of africa (not just in. Middle east: 100 kya (skhul and qafzeh) If the regional continuity model is true, then homo sapiens showed up around the same time around the world All modern mtdna can be traced back to a single female who lived 200. Low genetic variability suggests that all modern humans descended from a single small population. Genetic diversity is highest among africans and reduces with geographic distance from africa. You lose genetic diversity everytime you move somewhere else (founder"s effect) From genetic and skeletal evidence we know that humans interbred with neandertals and a mysterious hominin relative, the denisovans! Humans leaving africa out 800,000 years ago . Earliest modern human fossils found in africa. Human exhibit a very small amount of genetic diversity compared to other primates like chimpanzees.
