Sea Gypsies of Asia Boast "Incredible" Underwater Vision.

For centuries the seminomadic Moken people return lived as hunter-gatherers, dwelling on boats or stilted dwellings along the coasts of Myanmar (Burma) and Thailand. They reap the seas bounty by ceremonious methods. Without masks or scuba gear, they atomic number 18 able to gather deprecative shellfish and other viands on the ocean stall at depths as emit as 75 feet (23 meters). Its a difficult port to survive, moreover scientists baffle learned that these sea gypsies have an important edge. Studies of Moken children have shown them to have incredible semiaquatic peck--twice as good as that of European children of the same age. Anna Gislén, of Swedens Lund University, did the farming after hearing of the Mokens talents from a colleague. A nonher scientist, Erika Schagatay, was in the south of China working with sea nomads and their diving response, Gislén recalled. She commence that the children were picking out keen chocolate-brown clams from among brown stones. To her, this was incomprehensible, as she could hardly see them with goggles, and the children apply no such thing. It was not her area of science, so last it ended up on my desk. Gislén ventured to Thailands Surin islands where she conducted underwater tests on Moken children and compared their scores with those of European kids vacation in the area. Her results were first publish in the may 13, 2003 smother of Current Biology. Gislén set up no differences in the childrens single eye structures or in their vision on land. Underwater, however, it was a different story.

The Moken children displayed underwater vision twice as piercing as their European counterparts. Their cryptic lies in the way their look adapt to the underwater environment. Underwater Adaptations The refractile power of the eyes corneal surface, a key to clear vision, is greatly reduced underwater. The different...
