Among evolutionary biology's most persistent challenges is the challenge to explain why there are so many different species and why they tend to differ in ecologically relevant traits. This book, written by two evolutionary ecologists, reviews and synthesizes the role of competition in generating and maintaining biodiversity. The authors describe how trait evolution often arises as an adaptive response to resource competition or deleterious reproductive interactions between species. They also discuss how this process—known as “character displacement”—comes about and consider its myriad consequences. Indeed, the authors describe how the study of character displacement can illuminate some of ecology's and evolutionary biology's most fundamental problems, such as how to explain how new traits and new species arise, how species coexist, and how they subsequently diversify.
