What Did Ancient Humans Actually Fear After Dark?

Every night when the sun goes down, something ancient wakes up inside you. It's not irrational — it's 200,000 years of evolution. In this video, we explore why darkness triggers fear in the human brain, what our ancestors were actually afraid of after nightfall, and how fire, storytelling, and survival instinct shaped the mind you have today. Featuring research from anthropologist Polly Wiessner, anthropologist Richard Wrangham, and sleep scientist Matthew Walker. 🧠 Topics covered: Why your eyes and ears change at night What early humans really feared in the dark How firelight shaped human storytelling and myth The science of the amygdala and nighttime fear Why humans still fear the "unknown" more than known threats If you've ever felt a chill walking past a dark hallway or alley, this video explains exactly why — and why it's not a flaw, it's an inheritance. #Psychology #Evolution #Science #HumanBrain #Anthropology
