Sea Gypsies of Asia Boast "Incredible" Underwater Vision.

For centuries the seminomadic Moken people have lived as hunter-gatherers, dwelling on boats or stilted dwellings along the coasts of Myanmar (Burma) and Thailand. They harvest the seas bounty by stately methods. Without masks or scuba gear, they are able to gather censorious shellfish and other food on the ocean standstill at depths as low as 75 feet (23 meters). Its a difficult port to survive, but scientists have learned that these sea gypsies have an important edge. Studies of Moken children have shown them to have incredible subsurface vision--twice as good as that of European children of the same age. Anna Gislén, of Swedens Lund University, did the coating after hearing of the Mokens talents from a colleague. Another scientist, Erika Schagatay, was in the treat of China working with sea nomads and their diving response, Gislén recalled. She realize that the children were picking out small chocolate-brown clams from among brown stones. To her, this was inco mprehensible, as she could hardly see them with goggles, and the children used no such thing. It was not her area of science, so eventually 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 pass in the area. Her results were first published in the may 13, 2003 come forth of Current Biology. Gislén found 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 disconnected as their European counterparts. Their secret lies in the wa y their eye adapt to the underwater environm! ent. Underwater Adaptations The refractive power of the eyes corneal surface, a key to clear vision, is greatly reduced underwater. The different... I dont esteem its enough to just paste quotes and string them unneurotic as you have in this paper, you need to give mind as to why you put them there, what youre trying to get at, what your plosive speech sound is....its not enough otherwise.
