Australopithecines and Paranthropus
Some anthropologists argue that the variations appear to indicate that several separate species of humans existed; other scientists lump all the individuals together in a single species.Homo habilis
These crude hand axes and stone flakes could have been manufactured as needed or as opportunity arose. The fracture lines of stones create a sharp cutting surface capable of butchering fairly large animals. The photo above right shows a modern anthropologist skinning a calf with a stone tool made just as ancient Homo habilis would have done.
Below are two fossils, shown to scale. KNM ER 1470 is to the left, and KNM ER 1813 is to the right. Originally, both were assigned to the species Homo habilis, with ER 1470 thought of as male and the smaller ER 1813 a female in a strongly dimorphic species. However, the anatomies of the two skulls differ considerably.
