Ayala is eminently qualified to write such a book, reviewer Joel W. Martin observes, especially because of his irenic attitude toward faith. The book is “well-written, accurate, and concise, and it covers the main points of biological evolution likely to be questioned by non-specialists,” although two of the questions Ayala addresses (What is DNA? and How Did Life Begin?) strike Martin as somewhat out of place. The final chapter (Can One Believe in Evolution and God?) is Ayala’s “most important contribution ... and it will be well received by persons of faith” but also draw flak from those “opposed to any such reconciliation.”
