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 oceans bounty by effected methods. Without masks or scuba gear, they are able to gather captious shellfish and other food on the ocean radix 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 submerged vision--twice as good as that of European children of the same age. Anna Gislén, of Swedens Lund University, did the destination after hearing of the Mokens talents from a colleague. A nonher scientist, Erika Schagatay, was in the atomic number 16 of China working with sea nomads and their diving response, Gislén recalled. She kick downstairs that the children were picking out small chocolate-brown clams from among brown stones. To her, this was incomprehensible, 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 gist of Current Biology. Gislén found no differences in the childrens respective(prenominal) eye structures or in their vision on land. Underwater, however, it was a different story.

The Moken children displayed underwater vision twice as aggressively as their European counterparts. Their secret lies in the way their eye 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... I dont esteem its enough to just paste quotes and string them unneurotic as you have in this paper, you need to give purpose as to why you put them there, what youre trying to get at, what your steer is....its not enough otherwise.
