Absolute dating technique: potassium- argon dating, superposition. Olduvai gorge: first site to discover hominid fossils, tanzania, 50s-60s, led the excavation. Lewis and mary leakey: catalogue name. Common belief: no, believed only homo could make stone tools. Difference between stone maker and user: oh 7. Finally found a species to fit in with the tools. Creator of oldowan tools: homo habilis. Human is gracile, tool maker should be gracile. If the species is not hyper robust, then they must be gracile h. habilis. Oh 7 bones are small and thin gracile h. habilis: set up a new brain threshold of being homo. Zinj- 530 cc (already identified as australopith) Oh 7 (already identified as h. habilis) Made 600 cc the new minimum to be in genus homo.
