Australopithecus africanus

Australopithecus africanus is an extinct species of australopithecine which lived between about 3.3 and 2.1 million years ago in the Late Pliocene to Early Pleistocene of South Africa. The species has been recovered from Taung, Sterkfontein, Makapansgat, and Gladysvale. The first specimen, the Taung child, was described by anatomist Raymond Dart in 1924, and was the first early hominin found. However, its closer relations to humans than to other apes would not become widely accepted until the middle of the century because most had believed humans evolved outside of Africa. It is unclear how A. africanus relates to other hominins, being variously placed as ancestral to Homo and Paranthropus, to just Paranthropus, or to just P. robustus. The specimen "Little Foot" is the most completely preserved early hominin, with 90% of the skeleton intact, and the oldest South African australopith. However, it is controversially suggested that it and similar specimens be split off into "A. prometheus". A. africanus brain volume was about . Like other early hominins, the cheek teeth were enlarged and had thick enamel. Male skulls may have been more robust than female skulls. Males may have been on average in height and in weight, and females and . A. africanus was a competent biped, albeit less efficient at walking than humans. A. africanus also had several upper body traits in common with arboreal non-human apes. This is variously interpreted as either evidence of a partially or fully arboreal lifestyle, or as a non-functional vestige from a more apelike ancestor. The upper body of A. africanus is more apelike than that of the East African A. afarensis. A. africanus, unlike most other primates, seems to have exploited C4 foods such as grasses, seeds, rhizomes, underground storage organs, or potentially creatures higher up on the food chain. Nonetheless, the species had a highly variable diet, making it a generalist. It may have eaten lower quality, harder foods, such as nuts, in leaner times.
