A scientist attempts to answer the question of how humanity spread itself across the globe in this documentary produced for PBS. The Journey of Man focuses on the research of geneticist Dr. Spencer Wells, who wants to prove his theory that the global migration of man began with a tribe of Africans who, battered by famine and drought, left their home literally searching for greener pastures some 60,000 years ago. Wells leaves his laboratory behind and sets out on a research mission in which he attempts to trace the common genetic thread which connect such varied travelers as the Aborigines of Australia, the Bushmen of Nambia, and the Native Peoples of North America.
