An international team of scientists, including a former Museum curator, discovered the partial skeleton of 3.2 million-year-old "Lucy" in 1974. Formally known as Australopithecus afarensis, the remains of this species of human ancestor have provided valuable clues as to when and why humans began to walk upright and evolve larger brains. Visitors can see a cast of the original skeletal materials and reconstruction of what Lucy’s full skeleton might have looked. The original bones were returned to Ethiopia.
