The Bajau people of Southeast Asia, known as Sea Nomads, spend their whole lives at sea, working eight-hour diving shifts with traditional equipment and short breaks to catch fish and shellfish for their families. Researchers now report that the extraordinary diving abilities of the Bajau may be thanks in part to their unusually large spleens, a rare example of natural selection in modern humans.
