Lucy was an adult when she died. Scientists are able to determine this age because Lucy had fully erupted wisdom teeth (or third molars) and her bones appear fully fused. ...

Lucy, a 3.2 million-year old fossil skeleton of a human ancestor, was discovered in 1974 in Hadar, Ethiopia. The fossil locality at Hadar where the pieces of Lucy's skeleton were discovered is known to scientists as Afar Locality 288 (A.L. 288).

Lucy was found by Donald Johanson and Tom Gray on November 24, 1974, at the site of Hadar in Ethiopia. They had taken a Land Rover out that day to map in another locality. After a long, hot morning of mapping and surveying for fossils, they decided to head back to the vehicle.

Why was the discovery of Lucy so important?

Because her skeleton was so complete, Lucy gave us an unprecedented picture of her kind. In 1974, Lucy showed that human ancestors were up and walking around long before the earliest stone tools were made or brains got bigger, and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion.

Why did humans walk upright?

Numerous causes for the evolution of human bipedalism involve freeing the hands for carrying and using tools, sexual dimorphism in provisioning, changes in climate and environment (from jungle to savanna) that favored a more elevated eye-position, and to reduce the amount of skin exposed to the tropical sun.
