Recently discovered 2 million year old fossil specimens were presented at the April 18, 2011 meeting of the American Physical Anthropology Association and are still being analyzed.  The conjecture that they represent a transitional form between genus Australopithecus africanus and genus Homo habilis is being questioned by other scientists:  "Ian Tattersall of the American Museum of Natural History in New York City endorsed A. sediba as a distinct species, probably closely related to A. africanus. 'I wouldn’t classify it as the root of the Homo genus, though,' he commented."
