A recent study suggests the ancestors of humans may have come from Europe rather than Africa.
Saccorhytus coronarius was an ellipsoid shaped bag, with a big mouth, and was only about a millimeter long. It was also humans' earliest ancestor.
Did Australopithecus afarensis walk like humans or chimpanzees?
Standing no more than three and a half feet tall, these human ancestors hunted giant rats, lumbering lizards, and miniature elephants.
