fem. proper name, from French Lucie, from Latin Lucia, fem. of Lucius (see Lucian).
Nickname for one of the most complete skeletons of an early ancestor of humans ever found. Discovered in Ethiopia by Don Johanson, Tim White, and Tom Gray, Lucy lived approximately three million years ago. She walked upright, and anthropologists estimate that she was about twenty years old when she died. Lucy is considered one of the great finds of anthropology.
