The teeth of Australopithecus sediba have confirmed their relationship with a man

A detailed analysis of the remains of ancient primates - Australopithecus sediba, found in South African cave Malapa in 2008, and the structure of their teeth has allowed paleontologists to conclude that they were probably the direct ancestors of modern humans. The information was presented in a series of articles published in the scientific journal Science.

"We looked at the remains of the jaw, as well as the hands of Australopithecus, indicating that sediba lived in trees. The other parts of the body - the lower extremities, chest, spine - resembled a "mosaic" of archaic hominids and anatomical features characteristic of human traits, "- said Lee Berger (Lee Berger) from the University of the Witwatersrand (South Africa).

Remains, perhaps, the most ancient human ancestors, scientists are studying the end of 2008, after Berger and his son found at the bottom of the cave Malapa remains Australopithecus sediba. They managed to find time for it, that these hominids were very similar to Homo erectus and ate mostly fruits and bark of trees.

The research team Berger, this time conducted an analysis of three skeletons of Australopithecus, restoring relatively complete skeleton of a hominid of the species. Berger and his colleagues found in the study of Australopithecus few new facts that allow scientists to examine them in relation to their northern "competitors" - Australopithecus afarensis - the more likely the ancestors of man.

Thus, almost "human" teeth in the jaws of Australopithecus sediba were more like the teeth of Homo erectus teeth than Australopithecus afarensis or other ancient hominids. In addition, the structure of the bones of the pelvis these primates indicate their suitability to walk upright, but because of the "monkey" thighs gait they have been highly unusual. Berger argues that they have collected tons of facts testify that it is A. sediba, rather than the famous "Lucy" and her relatives Afar, were the ancestors of man.
