Australopithecus africanus En 1924, à Taung (Afrique du sud), des restes de crânes sont envoyés à Raymond Dart à Johanesburgh. Much research has focused on a comparison between the South African species A. africanus and Paranthropus robustus. He called it Australopithecus africanus, meaning “southern ape of Africa.” From then until 1960 almost all that was known about australopiths came from limestone caves in South Africa. Despite a recent rash of claims to the contrary based on misidentified fossils or erroneous dates (R. Leakey, 1970, 1973a, 1976a; Oxnard, 1975, 1979; M. Leakey, 1979), it has become increasingly evident that Dart was correct—Australopithecus was ancestral to Homo. [45] Major changes to the pelvis and feet had already taken place before Australopithecus. Ples,” an Australopithecus africanus skull from 2.7 million years ago found in 1947 at Sterkfontein, South Africa, and originally classified as Plesianthropus transvaalensis by anthropologist Robert Broom. Dart realised that the fossil contained a number of humanoid features, and so he came to the conclusion that this was an early human ancestor. Les restes fossiles de cette espèce ont été découverts en Afrique du Sud. The earliest evidence of fundamentally bipedal hominins is a 3.6 MYA fossil trackway in Laetoli, Tanzania, which bears a remarkable similarity to those of modern humans. [15] The scientific community took 20 more years to widely accept Australopithecus as a member of the human family tree. Click to enlarge image. [33] The genus Australopithecus with conventional definitions is assessed to be highly paraphyletic, i.e. Australopithecus anamensis was about the size of a modern chimpanzee but males were much larger than females, (ref.) The first Australopithecus specimen, the type specimen, was discovered in 1924 in a lime quarry by workers at Taung, South Africa. [21][22][23][24] Resolving this problem would cause major ramifications in the nomenclature of all descendent species. The spot where the first Australopithecus boisei was discovered in Tanzania. It was once assumed that large brain size had been a precursor to bipedalism, but the discovery of Australopithecus with a small brain but developed bipedality upset this theory. Australopithecus, group of extinct primates closely related to modern humans and known from fossils from eastern, north-central, and southern Africa. [41], According to A. Zihlman, Australopithecus body proportions closely resemble those of bonobos (Pan paniscus),[42] leading evolutionary biologist Jeremy Griffith to suggest that bonobos may be phenotypically similar to Australopithecus. Australopithecus fossils become more widely dispersed throughout eastern and southern Africa (the Chadian A. bahrelghazali indicates the genus was much more widespread than the fossil record suggests), before eventually becoming extinct 1.9 million years ago (or 1.2 to 0.6 million years ago if Paranthropus is included). [57][58], A study in 2018 found non-carious cervical lesions, caused by acid erosion, on the teeth of A. africanus, probably caused by consumption of acidic fruit. [50] Australopiths in general had thick enamel, like Homo, while other great apes have markedly thinner enamel. Cave sites where it is found have been dated approximately to 3-2.0 ma based mostly on biochronological methods (dating methods utilizing the relative chronologies of non-hominin animal fossils). The Australopithecus africanus material dates to between 2.6 and 2.8 Ma, and consists of many post cranial elements which provided crucial evidence for bipedal locomotion in australopithecines. Elemental signatures of Australopithecus africanus teeth reveal seasonal dietary stress. Where the two differ is that Au. Current dating suggests that Makapansgat Limeworks is the oldest hominin deposit in southern Africa, with Australopithecus africanus dating to between 3.0 and 2.6 Ma. Australopithecus africanus (česky též Australopiték africký) je druh vyhynulého hominida, žijící na přelomu pliocénu a pleistocénu, před 3 - 2 miliony let v jižní Africe, na území dnešní Jihoafrické republiky.Ačkoliv není geologicky nejstarším australopitékem, byl rozeznán jako první a je tudíž typovým druhem celého rodu.
