Biologist Nathan Lents joins Science Quickly to explore the vast
sexual diversity found across the animal kingdom. His new book, The
Sexual Evolution: How 500 Million Years of Sex, Gender, and Mating
Shape Modern Relationships, challenges the binary framework that
has long shaped biological research, arguing for a more accurate
and inclusive view of sex and gender. From alternative reproductive
strategies to overlapping traits, this episode reveals how nature
defies neat categories—and why science should, too. Recommended
