The ongoing argument about how human beings arrived on Earth is examined in this documentary. Scientist and ecologist turned filmmaker Randy Olson was born and raised in Kansas, where public schools have often been the scene of battles between advocates of intelligent design, and scientists who show evidence that supports Charles Darwin's theory of evolution. Wanting to know more about both sides of the ongoing debate, Olson interviews intelligent design spokespeople (including Michael Behe, Jack Cahill, and John Calvert) and lets them speak their mind while also pointing out the many holes in their argument. Olson also chats with a number of leading scientists and colleagues who explain why evolution has become accepted the world over, but as Olson notes, the pro-evolution speakers often sound smug and arrogant when they express their views, while the intelligent design advocates generally seem pleasant and polite, if more than a little misguided. So can these two sides learn to speak to one another? Can science survive its own spokespeople? And what intelligent designer would come up with the rabbit, which has to eat its own feces to digest new food? A Flock of Dodos: The Evolution -- Intelligent Design Circus received its world premier at the 2006 Tribeca Film Festival.
