Lucy
Lucy is a famous fossilized skeleton of an early human ancestor called Australopithecus afarensis, discovered in Ethiopia in 1974. Estimated to be about 3.2 million years old, she provides crucial insights into human evolution. Standing about 3.5 feet tall and weighing around 60 pounds, Lucy displayed a combination of tree-climbing adaptations and bipedal walking skills, offering evidence that walking upright was an early development in human ancestry. Her discovery helped scientists understand how modern humans evolved from ancient primates, highlighting our shared evolutionary roots.
