Evolution of Hominids,that includes us Humans.
Tracing our genetic history as to the old world Monkeys that roamed the Earth 25 million years ago.Discoveries of various remains,including those of the famous Australopithicus Aferensis skeleton,commonly called Lucy.have helped us piece together an idea of our ancestory . It is believed around 7 or 8 million years ago we split from the chimpanzees and the process of evolution onto bipedal Homo Sapiens began,as these primates started to spend more time on the ground than in the trees.
