Virtually all serious scientists accept the truth of Darwin's theory of evolution. While the fight for its acceptance has been a long and difficult one, after a century of struggle among the cognoscenti the battle is over. Biologists are now confident that their remaining questions, such as how life on Earth began, or how the Cambrian explosion could have produced so many new species in such a short time, will be found to have Darwinian answers. They, like most of the rest of us, accept Darwin's theory to be true. But should we? What would happen if we found something that radically challenged the now-accepted wisdom? In Darwin's Black Box, Michael Behe argues that evidence of evolution's limits has been right under our noses -- but it is so small that we have only recently been able to see it.
