Australopithecus

Genus Australopithecus main The Australopithecus genus evolved in eastern Africa around 4 million years ago before spreading throughout the continent and eventually becoming extinct 2 million years ago.

However, because the "Ardi" skeleton is no more than 200,000 years older than the earliest fossils of Australopithecus, and may in fact be younger than they are, some researchers doubt that it can represent a direct ancestor of Australopithecus.

From Australopithecus sediba and his ongoing work today, he has made many significant findings that have furthered our understanding of human origins,” said Ian Miller, the Society’s Chief Science and Innovation Officer.

Other hominins existing at the time included the genus Australopithecus, known for the famous even-older fossil "Lucy" which was found in 1974 in northern Ethiopia.

She added: ‘Australopithecus afarensis would have roamed areas of open wooded grassland as well as more dense forests in East Africa around three to four million years ago.

Description All species of Paranthropus were bipedal, and many lived during a time when species of the genus Homo (which were possibly descended from Australopithecus), were prevalent.

However, after the discovery of the fossil in Kenya, it came to the notion that the K. platyops were one of the earlier species, living in the same time of the Australopithecus afarensis.

However, there has been human habitation in the region since time immemorial — sites in the Makapans Valley near Mokopane contain Australopithecus fossils from 3.5 million years ago.

In 1938 Paranthropus robustus bones were found at Kromdraai, and during 1947 several more examples of Australopithecus africanus were uncovered in Sterkfontein.

Initial analyses concentrated on comparisons to the Australopithecus afarensis A.L. 288-1 (" Lucy ").

Intelligence further Species of Paranthropus had smaller braincases than Homo, yet they had significantly larger braincases than Australopithecus.

It was seen as intermediary between gracile Australopithecus and Homo.

Modern monogamous primates such as gibbons tend to be also territorial, but fossil evidence indicates that Australopithecus afarensis lived in large groups.

Paranthropus is thought to have lived in wooded areas rather than the grasslands of Australopithecus.

That is sexual dimorphism is minimal, and other studies have suggested that Australopithecus afarensis males were nearly twice the weight of females.

The cranial structure of the Kenyanthropus has a few similarities to the Australopithecus, such as brain size, parts of the nasal, the suborbital and the temporal regions, but the differences far outweigh the similarities leading to its new genus.

The Kenyanthropus also shows many differences to Homo, as well as Ardipithecus, which leaves only the Australopithecus.
