The science that allows us to understand sexual coercion by males is drawn directly from Darwin’s own work on sexual selection. There is, however, another layer here, because of course one cannot talk about the evolution of sexual aggression in male primates without pondering the social consequences of the same behavior in our own species. Are domestic violence and sexual assault simply human homologues of the same conduct seen in chimpanzees and baboons? Many social scientists bristle at this suggestion, with its invocation of biological determinism. This volume’s authors, many of them female researchers, do an excellent job of sensitively exploring the boundary between phenotype and environment that is the stuff of which human behavior is made… The editors of this volume deserve high praise for having avoided the weaknesses to which such collections are prone—the book is uniform in tone, and the papers are all of high quality. There are no polemical rantings here, nor are the contributors concerned with political correctness; the empirical evidence is what matters to them, and their analysis of it is perceptive and nuanced… Sexual Coercion in Primates and Humans is an important work and will be a valuable addition to the bookshelves of specialists and nonspecialists alike.
