Randy Thornhill is the Distinguished Professor of Biology at the University of New Mexico. He received his PhD in zoology from the University of Michigan in 1974. His research and teaching are in evolutionary biology, particularly the evolution of animal social life. Steven W. Gangestad is the Distinguished Professor of Psychology at the University of New Mexico. He received his PhD in 1984 from the University of Minnesota. His primary research is in evolutionary psychology and social/personality psychology. His general interests concern the ways in which humans' current psychological design is a product of evolutionary selection, and current research involves this issue in regard to phenomena that occur within close relationships such as sexual relationships, friendships, and familial relationships. Other research concerns the developmental expressions of adaptations.

"The authors provide an impressively up-to-date, thorough, and evenhanded review not only of recent work on human sexuality in relation to ovarian cycle stage, but also of relevant research on other taxa and of the latest theoretical and empirical work on sexual selection and antagonistic coevolution of the sexes. The result is a tour de force, and those who wish to refute it will have to come to grips with its forceful argumentation and impressive breadth ofinformation."--The Quarterly Review of Biology
