Stearns and Hoekstra have written an extremely useful and much needed book. Beginning with an appetizing set of examples they proceed first with a couple of particularly thoughtful chapters on "The Nature of Evolution" and "Adaptive evolution" and then cover more or less all of the important fields of evolutionary biology: genetic variation, evolution of sex, life history and history of life theories, sexual selection, molecular methods, speciation and comparative methods. They are conspicuously short on human evolution, but if you add a suitable text on that particular field you have a superb overview of current evolutionary biology: not more detailed than necessary, not more complicated tharn doing justice to the intricacies of reseach in this field straddling experimental and historical sciences, very well written and handsomely produced. In brief, a book which Darwin would have loved, if he had happened to read it for amusement...It is to be greatly recommended as an introduction to a deeper understanding of life on earth.After all evolution is what makes biology so much more exciting and relevant than the other sciences.
