Why is the human species capable of both extreme kindness and cold-blooded execution? Dr. Richard Wrangham explores the theory of human self-domestication, suggesting we essentially bred the 'bully' out of our species through ancestral capital punishment. This shift didn't just change our behavior—it reshaped our skeletons and birthed our very concepts of right and wrong.
Are our moral values divine truths or just sophisticated survival tools? Dr. Victor Kumar explores how gene-culture co-evolution has shaped everything from our physical reactions to alcohol to our deepest feelings of sympathy and respect. While we've evolved to cooperate in small tribes, we now face the unique challenge of navigating a digital world where performing morality is often easier than practicing it—leaving us to wonder if we've lost the rituals that truly bind us together.
Why do we feel an emotion as potentially catastrophic as love, and what do our fingers have to reveal about our fidelity? Evolutionary psychologist Robin Dunbar breaks down the startling biological reality that humans are essentially 'serial monogamists' by nature, driven by a neurochemical cocktail designed to ensure offspring survival. He reveals the 'show-off hypothesis' behind male risk-taking and explains why the common kiss is actually a sophisticated biological audit of your partner's immune system.
