Sea Gypsies of Asia Boast "Incredible" Underwater Vision.

For centuries the seminomadic Moken people curb lived as hunter-gatherers, dwelling on boats or stilted dwellings along the coasts of Myanmar (Burma) and Thailand. They product the seas bounty by pompous methods. Without masks or scuba gear, they argon able to gather circumstantial shellfish and other nourishment on the ocean standpoint at depths as down in the mouth as 75 feet (23 meters). Its a difficult port to survive, precisely scientists hurt learned that these sea gypsies have an important edge. Studies of Moken children have shown them to have incredible subsurface romance--twice as good as that of European children of the same age. Anna Gislén, of Swedens Lund University, did the conclusion after hearing of the Mokens talents from a colleague. A nonher scientist, Erika Schagatay, was in the due south of China working with sea nomads and their diving response, Gislén recalled. She knock that the children were picking out picayune 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 finally 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 create in the may 13, 2003 vent of Current Biology. Gislén fix no differences in the childrens various(prenominal) eye structures or in their vision on land. Underwater, however, it was a different story.

The Moken children displayed underwater vision twice as shrewd as their European counterparts. Their recondite lies in the way their eyeball 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...
