Au. afarensis belongs to the genus Australopithecus, a group of small-bodied and small-brained early hominin species (human relatives) that were capable of upright walking but not well adapted for travelling long distances on the ground. Species in the australopith group - … WebHuman walking is about 75% less costly than both quadrupedal and bipedal walking in chimpanzees. Some hypotheses have supported that bipedalism increased the energetic efficiency of travel and that this was an important factor in the origin of bipedal locomotion. Humans save more energy than quadrupeds when walking but not when running. british railways timetables 1950s

WebEarly hominins: adaptations for bipedalism. The evolution of bipedalism has often been assumed to be due to leaving the shelter of forest and woodland and coming down to the ground, and it has been further assumed that upright posture was both a necessary pre-adaptation for bipedalism and itself an indication of its presence.
