Often I love the idea of science fiction more than science fiction itself. I’ve read most of the classics, and I am left with junk at the relevant margin. But lately I’ve been wrapped up in Stephen Baxter’s Evolution, published earlier this year. The book, spanning almost six hundred pages, tells the story of evolution from the point of view of our genes. To be sure, the book would be easy to satirize. It has no central characters, covers 65 million years of history, and frequently presents how different animals think [sic] about copulation. OK, that doesn’t sound like an obvious recipe for success but Baxter pulls it off to a surprising degree. The treatment is reminiscent of H.G. Wells or Olaf Stapledon, a particular favorite of mine. If you, like me, are desperate for science fiction that is actually intellectually stimulating, give this book a try. We are told, by the way, that the capacity to believe contradictory ideas is what makes human beings special.

Baxter pushes the Stephen Jay Gould line that the results of evolution are highly dependent on small accidents. For a contrasting point of view, from a more scientific front, see Life’s Solution: Inevitable Humans in a Lonely Universe. The author Simon Conway Morris argues that the path of evolution is much less contingent than is commonly believed. He points to numerous biological structures, such as the eye, that have evolved repeatedly under different guises. Here is one brief summary, here is a longer and more critical presentation. Life’s Solution, which occasionally verges on theology, should be read with a critical eye. Nonetheless if you feel you have read all the good popular books on evolutionary biology, here is a text with something new and provocative.
