Why Humans STOPPED Changing Physically | 50,000 Years Ago | HISTORY FOR SLEEP Why Did Humans Stop Evolving? 🧬 Ever wonder why you look almost identical to humans from 50,000 years ago? 🤔 While every other species on Earth continues to adapt and change, anatomically modern humans seem frozen in time. But there's a fascinating reason why... In this episode of Sleepy Time History, we explore the mystery of our evolutionary pause. Discover what caused the last major physical changes in human anatomy, how a near-extinction event locked our genes in place, and why culture ultimately replaced biology as our primary tool for survival. 🧠 Learn about the incredible brain trade-off that prioritized intelligence over physical adaptation, how human migration prevented us from splitting into different species, and why modern selective pressures simply don't exist anymore. We'll also reveal the subtle microevolution still happening today—you just can't see it yet. 👀 Perfect for history enthusiasts, science lovers, and anyone curious about human evolution and anthropology. Settle in as we uncover the incredible story of the species that literally evolved to stop evolving. ✨ Don't forget to subscribe to Sleepy Time History for more fascinating deep-dives into human history that'll make you think before you drift off to sleep! 😴 #HumanEvolution #History #AnthropologyExplained Check more of our videos here: https://www.youtube.com/playlist?list=PLz4qRohCjQXM7uAWCl4nvh2R25dbceo_2 Recommended: https://youtu.be/TOQt7GMt9Sk Chapters: 00:00 Introduction: The Mystery of Our Frozen Evolution 05:15 The Last Major Physical Changes: What Made Anatomically Modern Humans 20:16 The Population Bottleneck: How Near-Extinction Locked Our Genes 36:15 Culture Replaced Biology: When Tools Became Our Evolution 53:36 The Brain Trade-Off: Why Intelligence Stopped Body Modifications 1:07:55 Migration and Genetic Mixing: How Movement Prevented Speciation 1:23:25 Environmental Stability and the End of Selective Pressure 1:39:51 Modern Humans and Microevolution: The Subtle Changes Still Occurring 1:56:55 Conclusion: The Species That Evolved to Stop Evolving Disclaimer: We aim to present history as accurately as possible.
