Human Ancestor Reconstructed, Halfway Between Chimp And Human
In 2008, researchers found remains of a few early human-like beings in a cave in South Africa. Now, they’ve pieced them together into one of the most complete skeletons of a human ancestor ever made.
The skeletons belong to a new species of australopithecine, named Australopithecus sediba, discovered for the first time at that cave five years ago. Australopithecines comprise several different species of hominids that roamed Africa from about 4 million to 2 million years ago. They varied in form; some were more chimp-like, some more human like. The new Au. sediba appears to be right in the middle, with chimp-like feet (pigeon-toed, with a small heel) but also walking more upright than apes.
