Until now scientists believed that present-day homo sapiens had a single common ancestor -- Australopithecus afarensis, identified in 1974 with the discovery of the skeleton ``Lucy'' in Ethiopia. But a team of paleontologists led by mother and daughter Meave and Louise Leakey, say the hominid they found, dubbed Kenyanthropus platyops, is totally different from Australopithecus. ``It revolutionizes the way we look at human ancestry,'' Louise Leakey told Reuters. ``We have found a very flat-faced 3.6 million-year-old …showed first 75 words of 186 total…

After two years of exhaustive testing on the skull, Leakey said they had accumulated enough evidence to declare not only the discovery of a new species but a new genus as well. Kenyanthropus had a much flatter face than Lucy as well as particularly small molar teeth, leading scientists to believe it fed on a mixture of fruit, berries, grubs and small mammals and birds.
