Australopithecus Afarensis (Lucy)
Found by the palaeontologist Richard Leakey at Afar in Ethiopia in 1974. Lucy is the most complete specimen of a species of bipedal ape so far found. It roamed Africa about four million years ago, suggesting that changes in the climate made it advantageous for some tree-dwelling primates to live on the ground.
Lucy was about four feet tall; later versions of the australopithicus seem to have been taller and more robust and it is assumed that they are our earliest ancestors.
