Understanding our link to the Great Apes—the 2003 Benjamin Franklin Medal in Life Sciences awarded to Jane Goodall

Abstract Jane Goodall is the recipient of the 2003 Benjamin Franklin Medal in Life Sciences for her long-term scientific studies of chimpanzee behavior. Not only were her studies the first of their kind, her meticulous behavioral recordings led to major changes in our understanding of the social links that exist between ourselves and our closest living relative, the chimpanzee. In discussing the importance of Dr. Goodall's work, Stephen Jay Gould (the late Alexander Agassiz Professor of Zoology at Harvard University) said ... “Science gains enormous power in replications of observations, but Homo sapiens is a single species and we can never know, by studying ourselves alone, whether important aspects of our behaviors and mental capacities reflect an ancestral evolutionary heritage (transmogrified through our uniquely evolved intelligence and its social correlates), or new features evolved or socially acquired only by our lineage. Chimpanzees are the best natural experiment we will ever have for exploring this central question, for chimps are our closest genealogical cousins and therefore hold more of our common evolutionary heritage than any other species can. Chimpanzees are not so much the shadow of man as our mirror, only slightly blurred by the mists of time”.
