This book is about more than modern relationships; it’s about modern debates over who is male or female and why many people say they’re not the gender they were assigned at birth. An evolutionary biologist at John Jay College, Lents takes a compassionate and rational approach to these subjects, explaining that much of the misunderstanding surrounding them comes from the imprecise language we use to talk about sex and gender. Lents sheds light on the comparative biology and ethnology behind the most controversial aspects of human reproduction: the universality of masturbation and promiscuity among mammals and other animals; the forms “gay” sex takes among species, ranging from bedbugs to seabirds to those “sluttiest creatures,” the socially peaceful bonobos; the chemical and microbiological processes underlying the reasons embryos develop into babies that present as one sex at birth while feeling like another sex trapped inside their body as they get older. “When an organ doesn’t form in the typical way,” Lents writes about “intersex” embryos, “we usually call this a ‘defect’ or an error….[A]natomical tweaks are the raw material for evolution’s creative potential. They are not errors or defects. They are simply variations.” Variation is the watchword in this informative and often very funny book. Lents, a gay married man with adopted children, has some stake in these debates, and he isn’t shy about sharing his thoughts on the dangerous impact of religion and conservative cultural values on people who vary from the statistical norm. People with those views may be scandalized by Lents’ arguments, but they would do well to read this strong case against their positions.
