Australopithecus sediba


In what could rewrite the story of human origins, palaeontologists have discovered two ancient skeletons in South Africa, which they claim suggest that true humans may have emerged later than previously believed.

An international team, led by Lee Berger of University of Witwatersrand, has spotted the 1.9 million-year-old fossils of the two skeletons — possibly from a mother and son, having human and ape-like traits — in a South African cave.

It is suggested that this species, called Australopithecus sediba, may be a transitional species between the southern African Australopithecus africanusand either Homo habilis or even the later Homo erectus (Turkana boy, Java man, Peking man). The species has long arms, like an ape, short powerful hands, a very derived, Homo-like pelvis and long legs and was capable of striding and possibly running like a human, although the femur and tibia are fragmentary and the foot is more primitive.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
