Scientists in South Africa believe a two million-year-old creature could be the "missing link" between apes and humans. The fossilised skeletons of a female and child, known as Australopithecus sediba, were discovered in the Malapa caves near Johannesburg in 2009.
Professor Lee Berger who led the team that found Au. sediba, said: "The fossils demonstrate a surprisingly advanced small brain, a very evolved hand with a long thumb like humans, a very modern pelvis, but a foot and ankle shape never seen in any hominin species that combines features of both apes and humans in one anatomical package."
