Sea Gypsies of Asia Boast "Incredible" Underwater Vision.

For centuries the seminomadic Moken people absorb lived as hunter-gatherers, dwelling on boats or stilted dwellings along the coasts of Myanmar (Burma) and Thailand. They craw the oceans bounty by courtly methods. Without masks or scuba gear, they argon able to gather fault pick uping shellfish and other solid food on the ocean standpoint at depths as impression as 75 feet (23 meters). Its a difficult port to survive, exclusively scientists afford learned that these ocean gypsies have an important edge. Studies of Moken children have shown them to have incredible subaqueous spate--twice as good as that of European children of the same age. Anna Gislén, of Swedens Lund University, did the elaboration after hearing of the Mokens talents from a colleague. Another scientist, Erika Schagatay, was in the siemens of China working with sea nomads and their diving response, Gislén recalled. She find that the children were picking out subtle chocolate-brown clams from among brown stones. To her, this was incomprehensible, as she could hardly see them with goggles, and the children employ 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 promulgated in the may 13, 2003 go away of Current Biology. Gislén put to comeher 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 piercing as their European counterparts. Their privy(p) lies in the way their eyeball adapt to the underwater environment. Underwater Adaptations The refractive power of the eyes corneal surface, a key to clear vision, is greatly reduced underwater. The different...
