Australopithecus fossils become more widely dispersed throughout eastern and southern Africa (the Chadian A. bahrelghazali indicates that the genus was much more widespread than the fossil record suggests), before eventually becoming pseudo-extinct 1.9 million years ago (or 1.2 to 0.6 million years ago if Paranthropus is included).
It is thought that they averaged heights of 1.2–1.5 metres (3.9–4.9 ft) and weighed between 30 and 55 kilograms (66 and 121 lb). The brain size may have been 350 cc to 600 cc. The postcanines (the teeth behind the canines) were relatively large, and had more enamel compared to contemporary apes and humans, whereas the incisors and canines ...
Mrs. Ples is the popular nickname for the most complete skull of an Australopithecus africanus ever found in South Africa.Many Australopithecus fossils have been found near Sterkfontein, about 40 kilometres (25 mi) northwest of Johannesburg, in a region of Gauteng (part of the old Transvaal) now designated as the Cradle of Humankind World Heritage Site.
Homo (from Latin homÅ 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
Broom discovered fossils of Australopithecus that contributed to the acceptance of Dart's interpretation of the Taung child, as a transitional form between apes and anatomically modern humans. Dart's claim that Australopithecus africanus , the species name that he had given to the Taung Child, was a transitional form between apes and humans was ...
This constriction is very noticeable in non-human primates, slightly less so in Australopithecines, even less in Homo erectus and completely disappears in modern Homo sapiens. [1] Post-orbital constriction index in non-human primates and hominin range in category from increased constriction, intermediate, reduced constriction and disappearance ...
The skull KNM-ER 1470 (now H. rudolfensis) was at first dated to 2.9 million years ago, which cast doubt on the ancestral position of both A. afarensis or A. africanus, but it has been re-dated to about 2 million years ago. [8] Several Australopithecus species have since been postulated to represent the ancestor to Homo, but the 2013 discovery ...
Along with similarities to contemporary Homo, they share several characteristics with the ancestral Australopithecus as well as early Homo (mosaic evolution), most notably a small cranial capacity of 465–610 cm 3 (28.4–37.2 cu in), compared with 1,270–1,330 cm 3 (78–81 cu in) in modern humans.
