South African Scientists Discover New Hominid Species

The discovery of 2-million-year-old fossils may shed new light on the origins of human evolution, the Associated Press reports. According to a report published in the journal Science, two partial skeletons were found in a cave in South Africa and are believed to be 2 million years old, placing them within the Australopithecus primate group. Scientists have named the skeletons—which they claim are a new species—Australopithecus sediba. One of the skeletons belongs to a woman in her 20s or 30s, NPR says, and the other to a boy between the ages of 9 and 13. Because of their unusual bone structure, study author Lee Berger claims that the Australopithecus "provide[s] a window into a critical period when hominids made the committed change from dependency on life in the trees to life on the ground."-- Read original story in Associated Press.--Bilden: Professor Lee Berger, of the University of the Witwatersrand, right, and his son, Matthew, left, at the reveal of one of two nearly 2 million-year-old skeletons unearthed in South Africa, at Maropeng, near Johannesburg, Thursday, April 8, 2010.
