GENERAL KNOWLEDGE

Detailed explanation-1: -Its story began to take shape in late November 1974 in Ethiopia, with the discovery of the skeleton of a small female, nicknamed Lucy. More than 40 years later, Australopithecus afarensis is one of the best-represented species in the hominin fossil record.

Detailed explanation-2: -They presented their findings to a team of researchers and the group ultimately agreed that Lucy was part of a single, previously undiscovered, species of hominin. This newly identified species, Australopithecus afarensis, was announced by Johanson in 1978.

Detailed explanation-3: -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.

Detailed explanation-4: -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. Bipedalism, it seems, was the first step towards becoming human.
