As the debate over Intelligent Design has raged in America's schoolrooms and courthouses, one challenge to Darwin's Theory of Evolution has had tough staying power with non-scientists: how can a feature as delicately engineered as the human eye have arisen from a series of random mutations? That's the question Darwin couldn't answer, and the one that stumped Watson and Crick too.

But now, a bold and bright new theory, proposed by two Evolutionary Biologists, might have yanked the curtain off of biological complexity. This theory accounts for the appearance of the bat's wing, the human arm, and yes, the eye. And it reveals with elegant simplicity the core processes that have been at work for the last 3 billion years engineering the world as we know it.

Hear a conversation on a more complete Theory of Evolution and a rebuttal of Intelligent Design.

Marc Kirschner, professor and chair of the Department of Systems Biology at Harvard Medical School and co-author of "The Plausibiliy of Life, Resolving Darwin's Dilemma."
