September 09, 2011 – Scientists in South Africa say they have discovered a potential missing link in the evolutionary chain, after they claim to have found the fossilised remains of our earliest ancestors.
Australopithecus sediba, whose remains were discovered in a South African cave three years ago, had a long thumb and relatively short fingers like modern man, and a brain shaped more like that of a human than a chimpanzee.
Until now it was believed that our earliest identifiable ancestors were Homo habilis or Homo rudolfensis, fossils found in East Africa. But the newly discovered creature, described in five papers in the journal Science today, is several hundred thousand years older.
Prof Lee Berger, from the University of the Witwatersrand in Johannesburg, said: “The many very advanced features found in the brain and body, and the earlier date, make it possibly the best candidate ancestor for our genus, the genus Homo.†(TT)
