Anthropology 100 Lecture Outline The Rise of the Homo Line  1. Homo Habilis (for photos of fossil, click here. ) - Homo habilis had a number of differences from Australopithecus Africanus - most important was significantly increased brain size - correlated with important behavioral innovation: first evidence of stone tools - the type of technology is known as Oldowan toolmaking , and it produces pebble choppers and flakes . - Habilis diet was mainly vegetable, with some occasional meat derived from scavenging 2. Homo erectus (for photos of fossil, click here. ) - was larger, had larger brain than Habilis - appears to have had considerable sexual dimorphism - technology was more advanced than Habilis - used Acheulean tools , of which the characteristic example is the hand axe - Erectus spread across Old World, leading to physical and technological variability - some have proposed dividing Erectus into three distinct species: Homo ergastor (the populations in Africa), Homo heidelbergensis (the populations in Europe), and
