The discovery is about 40% of the skeleton of a female about 1.10 meters tall, about 27 kg in weight (when she was alive), about 20 years old (the wisdom teeth were just out) and that he had a child. Equipped with a tiny skull, comparable to that of a chimpanzee, Lucy walked on her hind limbs, a formal sign of an evolution towards hominization. Lucy's bipedal ability can be deduced from the shape of her pelvis, as well as her knee joint.
