THe Australopithecine was mainly vegetarian; Walker says the change to carnivorous came later. The steps he developed for this change and the results from it are thought-provoking. He thought that the time freed up from feeding (from 6-2 hours) might have been spent in socializing and idle experimnetation-- thus to tools and language.

short gut came in but I don't think it was with the Australapithecine The naming of genus is a bit arbitrary and does not illustrate descent (which is now called cladistics). There were many types of Australapithecine broken into two main categories, those who began to re-adapt to forest life and those who had to stick to the grasslands. During transitions between ice ages both the forests and grasslands were patchy as one landscape would slowly change to another. This left groups isolated from each other and their characteristics were not homogenized by interbreeding. There were different tribes in different forests, and another group of scattered tribes in a variety of grasslands. The route out of Africa was never widely forested and so it was the grassland adapted apes from North Africa which were able to cross the middle east and enter the huge expanse of Europe and Asia. In the next great ice age the European and Asian grass was mainly replaced by tundra and these clever apes returned in number to the growing grasslands of Africa, where they displaced the remaining grass adapted Australiphithecine in the south of the continent. A sizable number of homo erectus also moved to the great grass sea that is now China. TP The ice sheets ultimately retreated again.
