Document Summary

Describe key adaptations that distinguish humans from non-human primates. Describe hypotheses for the evolution of bipedalism in humans. Describe traits formerly attributed only to humans that are found in other species. Upright posture and bipedal motion are key adaptations distinguishing hominids from apes. Primates have power grip, humans have power grip and precision grip. The african emergence hypothesis: proposes that modern humans first evolved in africa and then dispersed to other continents; all modern humans are descended from a fairly recent. The multiregional hypothesis: proposes that after archaic humans migrated from africa to many regions on earth, their different populations evolved into modern humans simultaneously. Geographically isolated, but may have experienced differentiation; gene flow prevented reproductive isolation. Made tools, built shelters, hunted and buried their dead. Explain why humans are more correctly described as sharing common ancestry with chimpanzees", rather than the incorrect descended from chimpanzees. " *comprehension, Chimpanzees still exist and continue to evolve independently.
