What is the most important fact about Lucy?
Lucy is the common name for the oldest bipedal hominin to ever be discovered by anthropologists. She is otherwise named AL 288-1. She is a collection of fossilized bones that once made up the skeleton of a primate from the Australopithecus afarensis species. She lived in Ethiopia 3.2 million years ago.
How old was Lucy Australopithecus when she died?
Therefore, scientists have suggested that Lucy was between 12 and 18 years old when she died. Evidence from Lucy’s skeleton, specifically features of her left os coxa (hip bone) and her limb bones, also support the conclusion that she was a fully mature adult individual (Johanson, Taieb, et al.).
What did we learn from Lucy?
In 1974, Lucy showed that human ancestors were up and walking around long before the earliest stone tools were made or brains got bigger, and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion. Bipedalism, it seems, was the first step towards becoming human.
What caused Lucy’s death?
New analysis suggests that Lucy—one of the most complete hominin fossils ever found—met a tragic end three million years ago. Lucy, our renowned hominin relative, died some 3.18 million years ago after plummeting from a tree, according to researchers from the University of Texas at Austin.

How did Lucy know that she was an ape?
