Australopithecus afarensis characteristics

They also had small canine teeth like all other early … Australopithecus had a number of characteristics that were more similar to the great apes than to modern humans. Australopithecus means ‘southern ape’ and was originally developed for a species found in South Africa. Males were up to 50 percent larger than females, a ratio that is similar to that seen in modern gorillas and orangutans. Au.

afarensis had both ape and human characteristics: members of this species had apelike face proportions (a flat nose, a strongly projecting lower jaw) and braincase (with a small brain, usually less than 500 cubic centimeters -- about 1/3 the size of a modern human brain), and long, strong arms with curved fingers adapted for climbing trees. Australopithecus africanus is an extinct species of australopithecine which lived from 3.67 to 2 million years ago in the Middle Pliocene to Early Pleistocene of South Africa. This is the genus or group name and several closely related species now share this name. The species has been recovered from Taung and the Cradle of Humankind at Sterkfontein, Makapansgat, and Gladysvale. compared with the earlier species, Australopithecus afarensis, the skull showed some slightly more human-like features such as a smaller brow ridge and a slightly arched (rather than flat) forehead area. For example, sexual dimorphism was more exaggerated than in modern humans. like all human ancestors, the spinal cord emerged from the central part of the base of the skull rather than from the back. The word afarensis is based on the location where some of the first fossils for this species were discovered – the Afar Depression in Ethiopia, Africa Australopithecus, (Latin: “southern ape”) (genus Australopithecus), group of extinct primates closely related to, if not actually ancestors of, modern human beings and known from a series of fossils found at numerous sites in eastern, north-central, and southern Africa.
