Just re-released in paperback is Richard Dawkins' latest book, "The Greatest Show on Earth: The Evidence for Evolution." As expected from one of the world's leading science writers, educators and popular defenders of neo-Darwinian evolution, the book is a lucid, well-argued case for the existence of a grand evolutionary past for all matter, especially the living kind.

To suppose that "Signature in a Cell" is a book that argues for intelligent design (ID) from a religious or even metaphysical perspective is to suppose badly. For this book makes a strong case for ID as a rigorous scientific argument for the origin of life.
