Charles Darwin knew that there was a significant event in the history of life that his theory did not explain. In what is known today as the “Cambrian explosion,” 530 million years ago many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin’s Doubt Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life — a mystery that has intensified, not only because the expected ancestors of these animals have not been found, but also because scientists have learned more about what it takes to construct an animal.
