The video explores the unique adaptations of the Bajo people, who live in Southeast Asia and have a culture centered around the ocean. They are known for their remarkable diving abilities, spending hours underwater daily. A 2018 study revealed that the Bajo have larger spleens, which help them manage oxygen scarcity during deep dives. This adaptation is linked to genetic differences that influence spleen size and blood vessel constriction. The video includes a quiz segment, where participants guess the most significant adaptation, ultimately revealing the correct answer as larger spleens.
