A Natural History of Rape: Biological Bases of Sexual Coercion
Randy Thornhill and Craig T. Palmer use evolutionary biology to explain the causes of rape and to recommend new approaches to its prevention. According to Thornhill and Palmer, evolved adaptation of some sort gives rise to rape; the main evolutionary question is whether rape is an adaptation itself or a by-product of other adaptations. Regardless of the answer, rape circumvents female choice of mate, a central feature of women's reproductive strategy. This is a primary reason why rape is devastating to its victims, especially young women.The authors address, and claim to demolish scientifically, many myths about rape bred by social science theory over the last twenty-five years. The popular contention that rapists are not motivated by sexual desire, they argue, is scientifically inaccurate.Although rape is biological, the authors do not view it as inevitable. Their recommendations for rape prevention include teaching young males not to rape, punishing rape more severely, and studying the effectiveness of 'chemical castration.' They also recommend that young women consider the biological causes of rape when making decisions about dress, appearance, and social activities. Rape could cease to exist, they argue, only in a society knowledgeable about its evolutionary causes.The book includes a useful summary of evolutionary theory and a comparison of evolutionary biological and social scientific explanations of human behavior. The authors argue for the greater explanatory power and practical usefulness of evolutionary biology. The book is sure to stir up discussion both on the specific topic of rape and on the larger issues of how we understand and influence human behavior.
