This undated handout image provided by National Geographic and Nature shows a computer enhanced image of a lower jaw, shown as a photographic reconstruction, and the cranium, based on a computed tomography scan of  of he KNM-ER 1470 cranium, discovered in 1972, combined with the new lower jaw KNM-ER 60000. A famous family of paleontologists says newly found fossils confirm their controversial theory that the human family tree may have sprouted some long-lost branches going back nearly 2 million years. Meave Leakey led a team of researchers in Kenya that claim what they dug up shows there once were two additional pre-human species besides the one that eventually led to modern humans. One of the researchers said these wouldn't be our direct ancestors, which are called Homo erectus, but more like very distant cousins. The study appears online Wednesday in the journal Nature.
