Document Summary

Louis leakey (1960: found cranium not to be of robust australopithecine, olduvai, gorge, northern tanzania, 1. 8 mya, homo habilis. Habilis is significant because earliest homo is manufacturer of earliest stone tool technology. Encephalization demonstrated by average cranial capacity of earliest homo ranges from 600-800 cc. Range within chimpanzee cranial capacity: significant that earliest homo has significantly larger cranial capacity than other early homos, more rounded cranial vault. No snout, projection, and teeth are reduced. All bipedal: by connecting this to the homo genus - suggests that this is our earliest direct ancestor. Evolutionary role by early homo: trends: East africa: omo, south ethiopia, koobi fora, kmn-er 1470 richard leakey. Cranial capacity 752 cc significantly larger than any of earlier hominines. General trends f early homo in comparison to australopithecine. Cranial anatomy: brain expansion 600-800 cc, thin walled no crests, rounded vault, weakly projecting ridges, variable facial proportions between individuals.
