Bone fragments of the fossil skeleton of 'Lucy' are displayed at the National Museum of Ethiopia in Addis Ababa, on November 19, 2024. She was, for a while, the oldest known member of the human family. Fifty years after the discovery of Lucy in Ethiopia, the remarkable remains continue to yield theories and questions. In a non-descript room in the National Museum of Ethiopia, the 3.18-million-year-old bones are delicately removed from a safe and placed on a long table. The 52 bone fragments, amounting to some 40 percent of Lucy's skeleton, was, at the time, the most complete ever found, and revolutionised the understanding of our ancestors.
