Episode notes

Sex and gender are at the center of heated debates—but what if much of what we believe isn’t rooted in biological truth? In this episode, Dr. Nathan Lents, author of The Sexual Evolution, reveals what nature and evolution really tell us about sex, gender, and human relationships. You’ll discover why diversity in biology—whether in sex, gender, or mating strategies—isn’t just common but essential for survival. We explore surprising examples from the animal kingdom, including same-sex partnerships, sex-changing species, and why monogamy is far less “natural” than we think.

Dr. Lents challenges the idea of strict binaries and explains how understanding nature’s complexity can reshape how we view ourselves and others. If you’re ready to replace myths with science and gain fresh insights into what makes us human, this episode is a must-listen.
