Google is celebrating with its customary doodle, the 41st anniversary of the discovery of the skeletal remains of 'Lucy' Australopithecus, who is proven to have lived around 3.2 million years ago in Ethiopia.
The doodle shows three stages of Lucy's evolution in place of 'oo' in the word 'Google.'
40 per cent of Lucy's fossilised remains were discovered intact and paleoanthropologist Donald Johanson named her Lucy after the Beatles song ' Lucy in the Sky with Diamonds.'
By studying her bones, in particular the structure of her knee and spine curvature, scientists discovered that she spent most of her time walking upright on two legs.
It was claimed that she resembled human beings very closely and was 3.7 feet tall and 29 kgs in weight.
