Australopithecus africanus — The word “Australopithecus” means “southern ape. Raymond Dart, professor of anatomy at Witwatersrand University in Johannesburg, was the first to study these fossils. In at Taung in South Africa, Dart discovered a fossil skull consisting of a full face, teeth and jaws, and an endocranial cast of the brain. The brain size was cc. Its age is currently felt to be around two to three million years old. Dart was convinced that some teeth were man-like and thus concluded a transition between apes and man.

His opinions on the matter of this particular skull were largely scorned by the scientists of this time who considered it nothing more than a young chimpanzee now considered to be about three years of age. The skull was soon known derisively as “Dart’s baby. With Piltdown Man’s human cranium and apelike jaw, it was hard to reconcile it to the Taung Child. Although Dart gave up fossil hunting for some time, all was not lost. Years after the discovery of the “Taungs child”, as it is known today, Dart and Broom found other Australopithecines at Kromdraii, Swartkrans and Makapansgat.

These finds of similar creatures seemed to vindicate Dart and Broom, and the scientific community again accepted their finds as they do today.
