Challenging some of the longest-held beliefs in evolution, some dating back to Darwin's time, virologist Frank Ryan delves into the mysteries of metamorphosis to rethink evolution as a nonlinear process—one that involves much more than patient, incremental mutation.
"In this scintillating book Frank Ryan gives us a skillful and detailed introduction to the intricate world of animal metamorphosis and to the astounding idea (pioneered by Donald Williamson) that the larval and adult forms of many animals were once wildly different creatures whose genomes melded during moments of extraordinary trans-species hybridization."—Stephan Harding
