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.

What is the primary lifestyle of the Bajo people that influences their unique adaptations?

• Mountain climbing

• Desert survival

• Deep-sea diving

• Forest foraging

Which physical change is most significant in the Bajo people to help them manage low oxygen levels?

• Special protein in the brain

• Larger spleens

• More powerful heart muscles

• Overactive stem cells in bone marrow

How much larger are the spleens of the Bajo people compared to the Salawan people?

• 30% larger

• 50% larger

• 70% larger

• 20% larger

What role does the spleen play during a deep dive for the Bajo people?

• It enhances vision underwater

• It regulates body temperature

• It stores and releases oxygenated red blood cells

• It filters toxins from the water

Which genetic factor contributes to the larger spleens in the Bajo people?

• Genes controlling blood vessel constriction

• Genes regulating insulin production

• Genes affecting skin pigmentation

• Genes influencing muscle growth
