Why You Flinch Before You Even Know What Scared You

There's a current running under everything you do — pulling from 300,000 years ago. Undertow explores the hidden forces shaping human behavior: the ancestral instincts, evolutionary leftovers, and forgotten ways of living still buried inside your modern brain and body. Every video takes one strange, overlooked question — about sleep, memory, social behavior, or survival — and traces it back to its evolutionary root, using real research, real scientists, and real history. If you've ever felt like something about modern life doesn't quite fit — like you're running old software in a new world — this channel is for you. New deep dives every week.
