Their marine hunter-gatherer existence depends notably on the food they collect through free diving. Another possible system of human adaptation to extreme environments with implications for hypoxia research is that of humans who engage in breath-hold diving. The Bajau, or "Sea Nomads," have engaged in breath-hold diving for thousands of years • Selection has increased Bajau spleen size, providing an oxygen reservoir for diving • We find evidence of additional diving-related phenotypes under selection • These findings have implications for hypoxia research, a pertinent medical issue Summary.

The diving reflex causes the spleen to get shorter and tighter. A large spleen means even more oxygen-carrying red blood cells can be pumped into the circulatory system during this process, allowing individuals to stay underwater for longer. People, like other mammals, experience something called the "diving reflex" when our heads are underwater. the result of practice, as in the case of the excellent underwater vision of Thai "sea nomad" children, or the result of adaptations which. A group of sea-dwelling people in Southeast Asia have evolved into better divers. When Dr. Ilardo compared scans from the two villages, she found a stark difference. On Thursday in the journal Cell, a team of researchers reported a new kind of adaptation — not to air or to food, but to the ocean. A similar diving adaptation has recently been proposed for an Indonesian tribe of sea nomads known as the Bajau, that have evolved larger spleens to deliver.

Breath-hold diving is an activity that humans have engaged in since Physiological and genetic adaptations to diving in sea nomads. Most people are only capable of holding their breath for a maximum of a couple minutes, but Bajau divers are capable of holding their breath for around five minutes and up to 13 minutes in some cases. The larger spleens the Bajau people have assist them in diving underwater, helping them hold their breath for longer durations than most people.
