XXXVIII JAR Distinguished Lecture
A New Kind of Ancestor:
New Light on the Earliest Origins of the Human Clade
Owen Lovejoy, Professor of Anthropology, Kent State University
A variety of anatomical and behavioral differences distinguish us from our nearest relatives, the chimpanzee. Until recently, however, the fossil record was largely mute with respect to the origin of one of these differences, our ability to walk upright. Why did humans adopt this peculiar form of locomotion? Did our last common ancestor with chimpanzees also walk upright or did we once "knuckle-walk" as chimpanzees do? What role did bipedality play in the emergence of other, relatively recent, unique human characters (e.g., brain size, language, tool-making, etc.). The newest addition to our knowledge about our ultimate ancestry is Ardipithecus ramidus from Aramis, Ethiopia. Its anatomy is revolutionary and requires substantial revision of current theories about the earliest phases of human evolution, especially those relating to our adoption of upright walking.
