Document Summary
There is controversy about reproductive strategies of early australopithecines, reduction in canines in au. Implies that male-male competition wasn"t as important: a lot of early human fossils were first discovered by the leakys in olduvai gorge, tool maker was named homo. Habilus: they named him before they even found him. Derived traits that homo habilis shares w/ modern humans: larger brain than australopithecus, reduced postorbital constriction (means that temporalis muscles is smaller, foramen magnum is further forward, flatter & lower faces, smaller molars, stone tools. Acheulean tools: 1. 5 mya, seen in parts of africa, europe, and western asia, could"ve been used as hand axes, butchery knives, killer frisbees, or display items (gifts, art, show off items) Stone tools: 2 categories, core tools, flake tools, acheulean tools were more advanced than the olduwan tools, finish this slide. It"s thought that maybe bamboo took over the acheulean tool industry.
