Why did humans become the “naked ape” while our closest relatives stayed covered in fur? In this Sleepy Time History episode, we quietly unravel the evolution of human body hair and the surprising science behind our bare skin. From our hairy ancestors on the African savanna to theories about cooling, parasites, sexual selection, and even the controversial aquatic ape hypothesis, we explore why our species shed its coat—and why we still keep hair on our heads, armpits, and more. You’ll learn how thermoregulation, disease, fire, clothing, and genetics all combined to shape the modern human body. We’ll compare ourselves to other “naked” mammals, trace the evolution of human skin, and look at how culture and beauty standards transformed body hair into something we groom, shame, or celebrate. If you love slow, relaxing deep dives into human evolution, anthropology, and ancient history, this calm, story-driven video is for you. Drift off while you learn: subscribe to Sleepy Time History for more soothing history and science stories to fall asleep to.

We act as directors and editors, using AI tools to help research and draft the script while we shape the narrative and verify facts. The narration comes from a digital replica of a professional voice actor, and the images are individually crafted artistic impressions using AI. Even with these tools, creating a story of this depth still takes hours of work. Please note that while the narrative is thoroughly based on historical research, its primary purpose is storytelling for entertainment and relaxation. As such, it is not intended to be used as a formal academic or scientific source. Thank you for your trust and support.
