Document Summary
Australopids: early hominin, show first signs of bipedalism: Knees and curvature of spine suggest uprightness. Dispersal out of africa for homo sapiens. Moving from pan group (chimps), to modern humans. Lucy: australopid representative, 40% of her skeleton was found, remarkable given her age of 3. 2 million years. In this area of east africa, several different hominids living together. Existing in the same world region at same time. Now only have 1 hominid species living in isolation. 2 mya find evidence of homo erectus in africa. Number of innovations from erectus: (1) bipedalism - running. Skeleton tells us about behaviour that occurred in homo erectus. Skeleton tells us about running in this species: wider hips that support back structure, your bum evolved in homo erectus. Can walk without good glutes (bum muscle) But need good glutes for running: long torso: Distance between rib cage and pelvis is longer relative to other hominids.
