Document Summary

Rise of the genus homo: they are all bipeds. Looking a the way the faces have changed. A. robustus 530 ccs; a. africansus 440 ccs; h. habilis 640 ccs: reorganization and expansion of the human brain, smaller, flatter face, reduction in the size of dentition, scavenging and tool making. What is a stone tool: cutting edge, breakage patterns. How were they made: percussion method: which is using a rock to cut another rock, modern flint knappers/experimental archaeology. When struck properly, stone fractures in a controlled. Apply pressure, which breaks off a flake. Increased protein consumption possibly linked to brain increase. Also see changes in the shape of our heads and teeth. We are relying more on the stone tools to break up our food. Australopithecines: primarily vegetarian, relied on skull/teeth. Homo: omnivores, meat in diet, relied on tools. Their foot is smaller then the modern foot. Homo possibly lived contemporaneously with australopiths species for 1 million years.
