Title: Original Intelligence
Description: "About six million years ago, the common population shared by chimpanzees and humans diverged into separate groups, one becoming chimpanzee, the other Australopithecus, the first link in our long human lineage. And while the human lineage left Africa and migrated across the face of the Earth, the chimpanzees, unable to construct a technology that makes migration possible, have remained marooned for more than five million years in a small corner of Africa.".

"In Original Intelligence, leading experimental psychologist David Premack and his collaborator Ann Premack present a joint effort in teasing out exactly what are the deep characteristics of the human mind as they draw upon their years of brilliant experimentation."--BOOK JACKET.
