Nathan Lents on the Evolutionary Lessons of Sex and Gender Diversity

Nathan Lents, a professor of biology at John Jay College of Criminal Justice, has devoted nearly 15 years to teaching a course on the biology of sex and gender. Those classroom discussions accumulated into his new book, The Sexual Evolution: How 500 Million Years of Sex, Gender, and Mating Shape Modern Relationships. In it, he argues that diversity is not an exception in the animal kingdom but a rule, and that accepting this truth reshapes both biology and culture.
