In a Tanzanian jungle, a Western scientist and a tribal medicine man follow a chimpanzee in search of new medicines. On the plains of Kenya, a woman learns a powerful lesson about family -- from orphaned elephants. And in the Florida Keys, a dolphin opens up the lines of communication with an eight-year-old boy suffering from a rare genetic illness. As humans learn more about animal intelligence, we also are discovering that animals have a lot to teach us. Those lessons are the provocative subject of Wisdom of the Wild, airing on Thirteen/WNET New York's award-winning NATURE series Sunday, June 3 at 8 p.m. (ET) on PBS (check local listings).
