Changing diet: most likely shifted to a diet with more meat in it. Australopithecus has a very wide ribcage and wide hipbones to accommodate their big guts (because of low quality vegetation: early homo has a narrower ribcage and hips. Barrel-chested: early homo has elongated lower limbs. Carnivorous diets require more movement: bones of other animals are found at early homo archaeological sites with scratches (cut marks) from early tools, early tools were invented primarily for butchery tools. Rocks that were collected from stream beds. Hit another rock on a core: direct hard hammer percussion.
