The fossils were thought to be slightly older than Australopithecus boisei (about 1.75 million years) and in addition, the teeth were smaller and the brain was calculated to be significantly larger. Louis Leakey became convinced that these fossils were in fact the ancestors of modern humans. It was determined that Homo habilis (as the fossils were named) overlapped with the robust australopithecines for roughly 1 million years. Homo habilis means "handy man" and was suggested to them by Raymond Dart.
A series of anatomical characters is to be found uniquely in Homo – for example, an increase in cranial vault height and thickness, reduced lower facial prognathism, and reduction in the size of premolars and molars and the length of the molar row – but what has always stood out the most is brain size.
