One of the most important developments in human evolution was the dramatic expansion in brain size which, according to the fossil data available so far, began atwo million years ago. Certain specimens recovered from deposits in East Africa apparently have brain capacities in excess of 650 cm3 and close to 800 cm3.

The leg and foot were those of a habitual two-footedanimal. The simultaneous occurrence of Homo habilis fossils and crude flakes anstone tools indicate that they used tools. There is no evidence that this early form, homonids ate meat.
