But if you want to hear something really gross-Barbara and John kept on having sex while she was pregnant! This book confines itself to the insights that we can gain into our sexuality merely by broadening our perspective to encompass other animal species. Scientists infer that the sex life of even our recent apelike ancestors was very different from ours today. What a waste of effort! As a beginning, let's consider normal sexuality by the standards of the world's approximately 4, species of mammals, of which we humans are just one. Some distinctive evolutionary forces must have operated on our ancestors to make us different.

Often it's also the cause of misery, much of which arises from built-in conflicts between the evolved roles of women and men. What a waste of effort! To the layperson, these features all seem almost too natural to require explanation. Here's the weirdest thing of all: Our standards of sexual conduct are especially warped, species-ist, and human-centric because human sexuality is so abnormal by the standards of the world's thirty million other animal species. The couple has sex repeatedly, and mainly or exclusively with each other. Marriage partners usually have sex in private, rather than being indifferent to the presence of other humans. On reflection, though, they prove surprisingly difficult to account for. What were those forces, and what really is so bizarre about us?
