A New View of Evolution

There have been lots of new books about evolution in the past decade or so. I tend to divide them into three categories:
  1. The Standard View: These are books that basically support the Modern Synthesis with some small tweaks here and there. They do not advocate major shifts in the way we look at evolution. Books by Richard Dawkins (The Greatest Show on Earth: The Evidence for Evolution), Jerry Coyne (Why Evolution Is True), Sean B. Carroll (Endless Forms Most Beautiful: The New Science of Evo Devo and the Making of the Animal Kingdom, The Making of the Fittest: DNA and the Ultimate Forensic Record of Evolution), and Ken Miller (Only a Theory) fall into this category.
  2. The New View: Some books make the case for a new way of looking at evolution. I'll call it the "New View." Many of Stephen Jay Gould's books fall into this category (The Structure of Evolutionary Theory). He refers to it as extending the modern synthesis. Most of the "extension" is based on a pluralist, rather than an adaptationist approach but other modifications are important. Two recent books by Michael Lynch (Origins of Genome Architecture) and Eugene Koonin (The Logic of Chance: The Nature and Origin of Biological Evolution) fall into this category. It's a view that I share.
  3. The Radical View: Some books advocate a more-or-less complete overthrow of the Modern Synthesis, replacing it with the author's pet theory. Examples are: Marc Kirschner, and John Gerhart (The Plausibility of Life: Resolving Darwin's Dilemma), James Shapiro (Evolution: A View from the 21st Century), Lynn Margulis and Dorion Sagan (Acquiring Genomes: A Theory Of the Origin Of Species), Massimo Pigliucci and Gerd B. Müllerand (editors) (Evolution - the Extended Synthesis), many others.
