From the back cover:
"Charles Darwin knew there was a significant event in the history of life that his theory did not explain. In what is know today as the " Cambrian explosion," many animals suddenly appeared in the fossil record 530 million years ago without apparent ancestors in earlier years of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life and makes a compelling case for the theory of intelligent design as the best explanation for the origin of the Cambrian animals and the biological information necessary to produce them."
