Origins: A Skeptic's Guide to the Creation of Life on Earth
Shapiro addresses the question of the origin of life on Earth from a scientific perspective. It is worth noting that Darwin was concerned with the origin of particular species, not with the origin of life itself, about which he had little to say. Shapiro presents a good explanation of the so-called "primordial soup" theory. He is especially interested in the possibility that clay deposits allowed long polymer chains of carbon atoms to form which led to the first organic molecules.
