The editors of Keywords in Evolutionary Biology commissioned leading biologists, historians of biology, and philosophers of science to explain in detail a host of concepts central to evolutionary biology, from adaptation to unit of selection. The book includes essays by Richard Dawkins, Stephen Jay Gould, Daniel J Kevles, Motoo Kimura, Philip Kitcher, Michael Ruse, Elliott Sober, Mary Jane West-Eberhard, and David Sloan Wilson. Ernst Mayr exclaimed, "What a splendid idea to have a critical discussion by established experts of the key words used in recent controversies in evolutionary biology. This helps the understanding of these controversies enormously."
