Sex Is a Spectrum: The Biological Limits of the Binary by Agustín Fuentes
Update: 2025-10-07
Description
Human biology is far more expansive than the simple categories of female and male
Being human entails a complex interplay of biology and culture, and while there are important differences between women and men, there are also many variations and overlap. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed*.
Our conversation explores patterns across animal species, bio-cultural roles and impact, historical perspectives on sex & gender, why men have nipples, how female hyenas are bad a**, where political and social structures can occlude progress & how an honest, science-based foundation is paramount for being curious, learning & talking about the human experience at large.
Agustín Fuentes is professor of anthropology at Princeton University. His books include Race, Monogamy, and Other Lies They Told You: Busting Myths about Human Nature; The Creative Spark: How Imagination Made Humans Exceptional; and Why We Believe: Evolution and the Human Way of Being.
