About the Author
Cacilda Jetha is a Portuguese physician and researcher whose groundbreaking work in human sexuality has challenged conventional narratives about monogamy and relationships. Born in Lisbon and later relocating to the United States, Jetha brings a unique blend of medical expertise and anthropological insight to her explorations of evolutionary biology and mating behaviors. Collaborating closely with her partner, she co-authored the influential Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships (P.S.), a provocative examination of prehistoric human practices that questions the origins of sexual jealousy and fidelity in contemporary society. Her writing demystifies complex scientific concepts, advocating for a more liberated understanding of human connection in an era of evolving social norms.
