Island Tribes Develop Superior Underwater Vision
Artifice_Eternity writes "I found this Washington Post article fascinating. A tribe of skilled divers known as "sea gypsies" have developed a previously unknown physiological adaptation that gives them better vision underwater. Most humans see poorly underwater, because water has a similar refractive index to the fluid inside the eye, making it difficult to focus incoming light. But children of the Moken tribe compensate by shrinking their pupils (the same way photographers reduce a camera's aperture size to increase sharpness). Their underwater visual acuity is more than double that previously thought possible in humans. The article also describes other adaptations discovered in recent years that challenge our understanding of what the human body and brain can do."

True. We Americans have been training ourselves for years to be blind to the damage we are causing the rest of the world, and I must say it is working exceptionally well.
Professional atheletes develop superior muscles, professional musicians develop superior hearing, and video gamers develop superior hand-eye coordination.
Island tribe members have better underwater vision?
This must explain the increase of those "voted off the island" being hired for full-pool emergency maintenance calls.
Don't blame Durga. I voted for Centauri.
This idea, with obvious commercial applications, and clearly not in use anywhere else, should be patented by the Moken tribe. Otherwise, some industrialized country will patent it and sell it to the grandchildren of the current Moken. The U.N. Convention on Biological Diversity supports the idea that indigenous people should be able to patent their discoveries. Go for it!
Greek myth, or Soviet Russia? After all it sounds like a case of Cow rides *You*.
