“Lucy” was the familial name given to the Australopithecus afarensis skeleton
found in the late 1970’s by Donald Johanson. Lucy and her species lived between
4.2 to 3.5 million years ago, she is estimated to be approximately 42”-48” tall
and weigh between 45-55 pounds. Because the skeleton was found 40% intact, the
majority of the skeletal structure of the Australopithecus afarensis can be
identified. The knees and the pelvis of Lucy and the companions found at the
same site suggest they were fully bipedal and walked on two legs. This is a
huge development in the argument of evolution, as it shows a link between the
quadropedal monkeys and the bipedal homo sapiens.
