Sex and Beauty: The Extraordinary Implications of Darwin’s Strangest Idea (Matt Ridley)
In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. Matt Ridley revisits Darwin’s revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution. Ridley also explores the scientific research into the evolution of bright colors, exotic ornaments, and elaborate displays in birds around the world. Charles Darwin thought the purpose of such displays was to “charm” females. Though Darwin’s theory was initially dismissed and buried for decades, recent scientific research has proven him newly right—there is a powerful evolutionary force quite distinct from natural selection: mate choice. In Birds, Sex and Beauty, Ridley reopens the history of Darwin’s vexed theory, laying bare a century of disagreement about an idea so powerful, so weird, and so wonderful, we may have yet to fully understand its implications. Matt Ridley is the bestselling author of The Rational Optimist and Viral: The Search for the Origin of COVID-19 (with Alina Chan). His books have sold over a million copies. Ridley served in the House of Lords from 2013 to 2021 and is a fellow of the Royal Society of Literature, the Academy of Medical Sciences, and an honorary member of the American Academy of Arts and Sciences. His latest book is Birds, Sex and Beauty: The Extraordinary Implications of Charles Darwin’s Strangest Idea.

New Research on The Evolution of Intelligent Life
The guests today are co-authors of a new paper in Science Advances titled: “A reassessment of the ‘hard-steps’ model for the evolution of intelligent life.” Jennifer Macalady is a Professor of Geosciences at the Pennsylvania State University. Her research is focused on microbial ecology and evolution, and interactions between microorganisms and Earth materials like minerals and water through geologic time. Daniel B. Mills is a postdoctoral researcher in the Orsi Geomicrobiology Lab at The University of Munich in Germany. His research focuses on the co-evolutionary history of Earth's surface environment and eukaryotic life—a topic he approaches by studying modern marine organisms and environments. He also applies this research to the ongoing search for exoplanetary biosignatures and technosignatures. Shermer, Mills, and Macalady discuss the Hard Steps model of the evolution of intelligent life, the Drake Equation, the Fermi Paradox, the Great Filter, and the Great Silence. They also cover the Rare Earth hypothesis, major transitions in evolution, the uniqueness of humans, and the search for biosignatures and technosignatures.

Sex Work, Ethics, and Evolutionary Psychology: What REALLY Happens on Sugar Daddy Websites?
What is a sugar daddy, really? The answer might disturb you. Brook Urick takes us into the shadowy world of sugar dating, where young women are lured into dangerous situations under the guise of financial security. From being a would-be sugar baby to becoming the public face of SeekingArrangement, Urick unveils the unsettling truth about these platforms and their role in enabling predatory behavior. Urick’s revelations go beyond personal experience. She exposes how these websites intentionally protect exploiters, with their founder even caught in a sting operation attempting to meet a minor. With the passage of FOSTA-SESTA in 2018, making these platforms criminally liable, she questions why they still exist. Her goal? To bring public awareness and legal scrutiny to an industry built on deception and harm. Shermer and Urick discuss the realities of sugar dating, the blurred lines between sex work and exploitation, and the psychology of men and women in the industry. They explore legal and ethical debates, feminist perspectives, and societal consequences of prostitution and pornography.
