Australopithecus sediba, species & # 39; hominids, who walked on his feet but still climbed trees less than 2 million years ago, has close evolutionary relationship by Homo genus, which represents a kind of bridge between primitive humans and their predecessors, according to a new study of the remains, discovered for the first time over 10 years ago. The work was published this Thursday in PaleoAntropoloġija journal.
It is about two partial skeletons: a young man called & # 39;Malapa hominin 1& # 39; (MH1) and an adult woman, & # 39;Malapa hominin 2& # 39; (MH2), found by paleoantropropologu Lee Berger and his colleagues in 2008 at the site & # 39; Malapa in the "Cradle of Humanity" (Africa & # 39; South). Since the discovery of the skeletons, the researchers have been collecting.
The new study presents the results of this work and contains an analysis of 135 fossils, including, among other things, skull, thorax, pelvis, extremities upper and & # 39; below, as well as -proporzjonijiet his body and walking mechanisms.
"The anatomiji are seen in Australopithecus sediba jġegħluna revalued the path by which we become human"Said one of the co-authors of the discovery, Jeremy DeSilva.
The challenge traditional view of evolution
In addition, scientists believe that Australopithecus sediba, adjusting for bipedaliżmu, spent & # 39; a lot of time to go & # 39; trees, "perhaps to find food and protect themselves from predators."
In addition, the researchers argue that this is actually a hominids unique species, Distinct from both Auralopithecus africanus, which it shares close geographical proximity, and the first members of the genus Homo (eg., Homo habilis) in East Africa and Africa & # 39; South. However, it also shares characteristics with both groups, suggesting a close evolutionary relationship.
"Our findings challenge the traditional linear view of & # 39; evolution," concluded DeSilva.
