같은 인간인데 유전자는 0.1%만 다른데, 생김새는 왜 이렇게 다를까?ㅣ7만년 전 인류 흔적

We are the same humans, yet our genes differ by only 0.1%; why do our appearances differ so much? Traces of Humanity from 70,000 Years Ago ---------------------- We originated from the same ancestor, yet our genes differ by a mere 0.1%. But why have our appearances diverged to such an extent? People who left Africa 70,000 years ago evolved into distinct body types amidst the scorching sun of the savanna, the humid shade of the Congo jungle, and the thin oxygen of the Andes and Tibet. Although the Maasai and Mbuti are both Africans, there is an average height difference of over 50 centimeters. Surprisingly, it has been revealed that the Tibetans' genes for high-altitude adaptation were inherited from the extinct Denisovans. The ability to digest milk and the tendency to blush when drinking alcohol are also traces left by the environments in which our ancestors lived. Despite these dramatically different bodies, the genetic difference across the entire human race amounts to a mere 0.1%. 🎬 Video Timeline 0:00 Why are our faces different? 1:06 The reason we left Africa 2:33 The secret of genetic diversity 4:18 Why our skin color has changed 6:20 Ancient humans hidden inside my body 9:14 The secret hidden in the shape of the nose 10:14 Why do we turn red when we drink alcohol? 11:53 Why did blue eyes develop? 13:11 The uncomfortable truth about racial classification 14:23 Why are we one? ⚠️ This video was produced using generative AI for educational and informational purposes. ――――――――― 📌 References This video was created based on the research below. · Research on Genetic Diversity in Africa — Sera Tishkoff, Science (2009) · Tibetan Alpine Adaptation and Denisovans — Emilia Huerta-Sánchez, Nature (2014) · Origin of European Lactose Persistence — Jan Itan, PLOS Computational Biology (2009) · The Black Death and the CCR5 Variant Diffusion Hypothesis — Alisson Galvani, Proceedings of the National Academy of Sciences (2003) · Comparison of Andean and Tibetan Alpine Adaptation — Cynthia Beale, Proceedings of the National Academy of Sciences (2007) 🔍 Humanity Magnifying Glass is a history channel that looks into ancient humans, ancient civilizations, and the hidden stories of the lives of people from the past.
