Bajau people, known as sea nomads, possess extraordinary free diving s𝓀𝒾𝓁𝓁s, allowing them to dive up to 230 feet for extended periods, showcasing remarkable human adaptation to marine environments.

Genetic studies indicate that the Bajau may have evolved unique adaptations, including an enlarged spleen, enhancing their ability to survive underwater for long durations.

Research suggests that modern Tibetans possess a gene inherited from Denisovans, enabling them to thrive at high altitudes by producing fewer red blood cells compared to non-adapted populations.

Inuit populations have adapted to a diet low in plant matter and high in fats, with genetic mutations that protect them against cardiovascular diseases and diabetes, allowing them to thrive in extreme Arctic conditions.

The Korowai tribe, known for living in tree houses, has developed unique adaptations for climbing, although their physiological differences remain unstudied.

Moken 𝘤𝘩𝘪𝘭𝘥ren, living in the Andaman Sea, exhibit exceptional underwater vision, able to see nearly twice as well as European 𝘤𝘩𝘪𝘭𝘥ren, demonstrating the impact of environmental adaptation on sensory capabilities.
