Human Ancestor Reconstructed, Halfway Between Chimp And Human

— PopSci

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.

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.
