Lucy (AL 288-1) is the set of bone fragments belonging to the skeleton of a hominid of the species Australopithecus afarensis, 3.2 to 3.5 million years old, discovered by the American Donald Johanson on November 24 from 1974 to 159 km from Addis Ababa, Ethiopia. It is about 40% of the skeleton of a female about 1.10 meters tall, approximately 27 kg in weight (when she was alive), about 20 years old (the wisdom teeth were just out) and that at It seems he had a son.
