Homo Habilis-The  First Tool Makers:

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.  Thesespecimens were taken to represent the first appearance of our om  kind and weretermed Homo habilis. The species name Homo habilis, means, literally, handy mHomo habilis walked upright.

The bones of  the hand, while displaying many characteristics of modern humans, are somewhat curved  in places and more robusthan in modern man, i.e. Homo sapiens. The leg and foot bones have characteristthat are both ape-like and human-like, but overall, they are much closer to those o,nodern humans than to apes. 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.
