Document Summary
Dentition, bipedal locomotion, large brain size, tool-making behavior. It is instead material from the text that i have condensed. Some things that make a hominin a hominin. Hominins now refer to all great apes and humans, together. Hominins were bipedal for at least 2 million years before evidence of tool use appeared. Habitual tool use and its positive effect on bipedal locomotion emphasizesdual role of biocultural evolution. Mechanics of walking on two legs; the bodt, step by step, teeters on the verge of catastrophe . Two hip bones (ossa coxae; sing. os coxae) joined at the back to the sacrum. In quadrapeds, the ossa coxae are vertically elongated when compared to that of hominins, which are shorter and extend around to the side. Foot acts as a stable support; push off with mainly big toe; legs became elongated to increase stride length. Hominin bipedalism is both habitual and obligate.
