Paleoanthropologists have long looked to early hominids to answer questions about our own development and evolution. The most famous example is the Australopithecus Lucy, who roamed the African savannah more than 3 million years ago.
Recently, paleoanthropologists have uncovered a fossilized foot close to Lucy’s age but with details resembling an older species of proto-human, Ardi. The find provides scientists with new details and information on the evolution of bipedalism in humans. To learn more about the discovery, see the article in Scientific American.
