The Fifth Miracle: The search for the origin of life, by Paul Davies, Penguin, 1998, 304 ff.
Theories of the origin of life
By Howard A. Jones
No, this is not a theology book, though it does take its title from the author's reading of Genesis where God is said to create the universe, light, firmament, land - and then life, all regarded as miracles. Setting theology aside, the rest of the book is a scientific description of theories - biological, chemical and physical - as to the origin of life on Earth. The author was a Professor at the University of Adelaide when this book was written and is now at the State University of Arizona where he is Director of a Center for Fundamental Concepts in Science, exploring subjects as diverse as cancer, which he proposes be studied in a non-traditional way, and the search for extra-terrestrial life.
In the opening chapter Davies makes it clear that he does not believe in vitalism, the existence of some kind of life force in living matter. He does however accept that living matter contains a unique type of information that allows self-propagation. There is a good discussion of the scientifically accepted (Darwinian) biological role of DNA and RNA here and in later chapters, but for any Lamarckian interpretation readers must turn to authors like Bruce Lipton. In fact, the whole book is more biological than others I have read by this author, but it's good to see Cairns-Smith's ideas of clay minerals as templates for nucleic acids getting some coverage. As usual in his books, Davies combines with fluency geology, biology, cosmology and metaphysics (about the meaning of life, for example) on a scientific bedrock of physics. Also as usual, there is no mathematics for readers to have to get their heads around. As might be expected from the title, there is more biology in this book than physics, but this is also in line with the author's current research interests. At the end, there are several pages of Notes that include References, and an Index set in a very tiny font size that's hard to read.
