Et funn i en hule i Sør-Afrika kan forandre vårt syn på menneskets forhistorie. De to skjelettene er datert til 1,9 millioner år. De er en type ukjent hominider som kalles Australopithecus sediba.
The discovery of the species, named Australopithecus sediba, suggests that true humans may have emerged later than previously believed and that there was a «transition» during which our ancestors divided their time between swinging in trees and walking upright.
Lee Berger, a palaeontologist at the University of Witwatersrand, who led the expedition, said: «We feel Australopithecus sediba might be a Rosetta Stone for defining what the genus Homo is. The fossils appear to present a mosaic of features demonstrating an animal comfortable in both worlds.»
