What is the four-letter name given to the famous fossil discovered in Ethiopia in 1974?

The famous fossil discovered in Ethiopia in 1974 is named Lucy, after the Beatles song "Lucy in the Sky with Diamonds," which was playing during the celebration of her find. Lucy is an important paleoanthropological discovery, as she belongs to the species Australopithecus afarensis, one of the earliest known relatives of modern humans. The significance of Lucy lies in her age, which is approximately 3.2 million years old, and the insights her skeleton has provided about early human bipedalism and physical structure. This discovery has helped scientists understand the evolution of hominins and the timeline of human ancestry, making Lucy a pivotal figure in our understanding of human evolution.
