15.Deep in the islands on the Andaman Sea,and along the west coast of Thailand live small tribes called the Moken people,also known as sea-nomads (海上牧民).Their children spend much of their day in the sea,diving for food.They are uniquely adapted to this job-because they can see underwater.And it turns out that with a little practice,their unique vision might be accessible to any young person.
In 1999,Anna Gislen at the University of Lund,in Sweden was delving different aspects of vision,when a colleague suggested that she might be interested in studying the unique characteristics of the Moken tribe.
Gislen and her six-year old daughter travelled to Thailand and lived within the Moken communities,who mostly lived on houses sat upon poles.Gislen set up an experiment to test just how good the children's underwater vision really was.The kids were excited about joining in.
The kids had to dive underwater and place their heads onto a panel(表盤).From there they could see a card displaying quite a few lines.Once they had stared at the card,they came back to the surface to report where the lines travelled Each time they dived down,the lines would get thinner,making the task harder.It turned out that the Moken children were able to see twice as well as European children who performed the same experiment at a later date.
Gislen figured that in order to see clearly underwater,the Moken children must have either picked up some adaptation that completely changed the way their eyes worked,or they had learned to use their eyes differently under water.
