Richard Dawkins: "The Greatest Show on Earth"

From deep in the archives, Michael's conversation with Richard Dawkins, author of "The Greatest Show on Earth: The Evidence for Evolution (A Brief History of the Natural World)." In the New York Times bestselling book, he launches a fierce counterattack against proponents of "Intelligent Design." "Intelligent Design" is being taught in our schools; educators are being asked to "teach the controversy" behind evolutionary theory. There is no controversy. Dawkins sifts through rich layers of scientific evidence—from living examples of natural selection to clues in the fossil record; from natural clocks that mark the vast epochs wherein evolution ran its course to the intricacies of developing embryos; from plate tectonics to molecular genetics—to make the airtight case that "we find ourselves perched on one tiny twig in the midst of a blossoming and flourishing tree of life and it is no accident, but the direct consequence of evolution by non-random selection."
