Centre of Gravity of the Body during the Ontogeny of Chimpanzee Bipedal Walking

摘要: Bipedal walking was studied in chimpanzees between 1 and 19 years of age by measuring the external energy generated movement centre gravity body. The ‘recovery’ infant less than five is smaller juveniles from 5 to age. During single stance phase, short, flexed hindlimb younger not able lift body high enough, so that these infants have a considerable output during bipedal walking. Extension one bases for economy human bipedalism. development this low-energy-cost mechanism an important component evolution
