Australopithecus africanus
Quick Summary
Australopithecus africanus was a species of early hominin that lived in South Africa between approximately 3.0 and 2.4 million years ago. The first discovered fossil of this species was the "Taung child," found in 1924. This fossil, a natural cast of a young child's skull, revealed humanlike teeth and a foramen magnum indicating an upright posture, despite its ape-sized brain.12
While initially met with skepticism due to its small brain size, later discoveries supported the idea that bipedalism preceded significant brain expansion in human evolution. A. africanus had specialized features for chewing, including larger cheek teeth and jaws. Males were approximately 138 cm tall and weighed 41 kg, while females were about 115 cm tall and weighed 30 kg. Their average brain size was around 448 cc. Fossils have been found at sites like Sterkfontein and Makapansgat.21

At first Broom ascribed his fossils to A. transvaalensis, a hitherto-unknown species. In 1947 he uncovered an adult skull so unique and well preserved that he proposed an entirely new…
