Google Doodle is celebrating the 41st anniversary of Lucy's discovery.
Lucy the Australopithecus refers to a collection of fossils belonging to a hominid that has remained largely intact.
The doodle places Lucy right in the centre of the 'March of Progress' showing the pivotal role she played in scientists' understanding of human evolution.
The find, made in 1974, allowed scientists to study Lucy's knee structure and spine curvature quite closely and conclude that she walked upright most of the time.
Carbon dating results also indicated that the fossils were 3.2 million years old and that the hominid would have been around 1.1 meters tall, weighing 27 kilograms.
She belongs to the Australopithecus afarensis species and analysis of other skulls belonging to the same species shows that she had an ape-like head with a low forehead, wide cheekbones and a projecting jaw.
While her origins are definitely ancient, her name is quite modern.
Lucy gets her name from the Beatles song 'Lucy in the Sky With Diamonds,' which reportedly came on while researchers were celebrating their discovery.
One of the biggest mysteries however, is we are still not sure about how she died.
In May, scientists discovered jaw bones and teeth, 3.3 to 3.5 million-years-old, which suggested Lucy had company.
Dubbed Australopithecus deyiremeda, the find indicated that humans have more ancient relatives than we first thought.
Its remains were dug up in Woranso-Mille, the same area where Lucy's bones were uncovered 41 years ago.
