Australopithecus afarensis is an extinct primate species, which to some, is considered to be the "missing link" in human evolution. The monumental remains known as "Lucy" stemmed from one of the most famous paleoanthropological finds in recent history. The potassium-argon dating found that the ancient species is thought to have lived between 3.9 and 2.9 million years ago. This discovery of the potential missing link remains the subject of heated discussions within many scholarly circles.
