Scientist Berger’s nine-year-old-son, Matthew; in a visit to Malapa (South Africa), found fossilised skeletons recovered from a deep underground cave.
Berger thinks they belong to a previously unknown species of human antecestor.
The partial skeletons of an adult female and a young female were lying side by side insediments that were recovered with, at least, 25 other animals, in a region dominated by a grassy plain and wooded valleys.
The skeletons were really well preserved, so the paleontologist belive they fell into the cave (which researches think was a “death trap”) and were dead and buried within days or weeks.
The remains are thought to represent a period of evolutionary transition between tree-dwelling apes and the hominids.
Lee Berger, asigned the remains to a new species, Australopithecus sediba. Sediba means fountain in Sotho, one of the official languages of South Africa,
Berger thinks, Australopithecus sediba may be descended from the more primitive South African ape men, Australopithecus africanus.
On the other hand, other experts argue that remains have been misclassified and belong to the genus Homo, so the transition to Homo is still confusing.
I taked this article from http://www.guardian.co.uk/science/2010/apr/08/fossil-skeletons-unknown-human-ancestor?INTCMP=ILCNETTXT3487 , where we can see this video: skull-australopithecus-sediba-human-ancestor of a reconstruction of the Australopithecus sediba’s skull.
The original source is http://www.sciencemag.org/site/extra/sediba/ . Here we can see the process of reconstruction of the skull, we can take the picture upside and read more about Australopithecus sediba.
In my opinion, even if we still don’t know to which genus the Australopithecus sediba belongs, any time remarkable fossils like this are found, in remarkable completeness, they are going to answer many questions, so it is going to contribute to the understanding of what was going on when the early members of Homo appeared.
