WebHumans are a challenge to this model because the relative proportions of our limbs, which are thought to reflect independent adaptations for bipedalism (14–16), endurance, running (), manual dexterity, and tool use (15, 18), distinguish us from all other primates (14–16, 19) (Fig. 1C).Importantly, the hominin fossil record indicates that these selective factors likely … WebBipedalism is a distinctive characteristic of humans; however, bipedalism did not appear suddenly. It has transited from quadrupedalism in both evolutional and developmental contexts. In an evolutional context, either terrestrial quadrupedalism 1 ) or arboreal locomotion with four limbs 2 ) is suggested to precede bipedalism. エコロジーライフ https://fairysparklecleaning.com
