Summary

If humans evolved for love, connection, and pair bonding, why does modern life feel so lonely?Today, we explore one of the most overlooked forces shaping human flourishing: intimacy. Joining me is evolutionary biologist and Executive Director of the Kinsey Institute, Dr. Justin Garcia, to discuss his groundbreaking book, The Intimate Animal: The Science of Sex, Fidelity, and Why We Live and Die for Love.In this conversation, we challenge the idea that love is purely cultural or emotional. Justin explains that romantic love is deeply biological — driven by neural systems that resemble addiction, shaped by millions of years of evolution, and essential to survival. Yet modern technology, shifting norms, and changing expectations are disrupting those ancient systems in ways we are only beginning to understand.We move from fMRI brain scans of people in love to the paradox at the heart of human relationships: we evolved for pair bonding, but not necessarily strict sexual monogamy. Justin reveals how commitment and novelty operate as competing evolutionary drives — and why this tension shows up in nearly every long-term relationship.If you’ve ever wondered why dating feels harder, why connection feels fragile, or why loneliness persists even when we’re constantly connected, this episode offers a biological roadmap for understanding the intimacy crisis of modern life.Passion Struck is the #1 alternative health and personal growth podcast dedicated to human flourishing and the science of mattering.
