Continental drift is the most commonly held scientific belief about the movement of Earth's species over time. But evolutionary biologist Alan de Queiroz challenges that notion by positing that certain species, from monkeys to baobab trees, were not merely victims of their continental fate but masters of their geographic destiny. Queiroz is the author of "The Monkey's Voyage: How Improbable Journeys Shaped the History of Life." Original air date 2/25/14
