The brain size of Homo habilis, one of the earliest members of the genus Homo, was larger than that of its ancestors, such as Australopithecus. While Australopithecus had a brain size ranging from about 300 to 500 cubic centimeters, Homo habilis had a brain size of about 510 to 600 cubic centimeters. This increase in brain size is associated with more advanced cognitive abilities, which enabled Homo habilis to create and use small stone tools known as Oldowan tools.
