I saw that report, all it was saying was that because young Japanese use txt msg on their phones so much, their thumbs are becoming more flexible, NOT a mutant gene.
Little Faith said:
Weirdly enough (and slightly gaming-related) young people in Japan with a peculiar mutation have been sighted. The mutation grants increased mobility and greater rotation of the thumb. People with the mutation are also more likely to use the thumb for various operations where other people would use the second or the third digit.
How exactly this mutation has developed is a mystery. The mutation seems clealy as an act of evolution adapting the individual to it's environment (which includes more thumb-operated devices). But the conditions that has warranted it's necessity has appeared in the cause of a single generation and the survival of the individual is hardly at stakes in the business. Therefore it cannot really be the effect of any Darwinian systems.
Such cases might be evidence that we don't really know how evolutions happens at all. In fact the only thing we know about evolution is that it appears to alter creatures so that they fit their surroundings better.
In a quiet technology-driven change, young Japanese are developing hyperagile thumbs, the fruit of childhoods spent furiously thumbing hand-held computer games and now young adulthoods spent thumbing out e-mail messages on cell phone key pads.
"Their thumbs have become bigger, more muscular," said Sadie Plant, author of a new report of "On the Mobile," (PDF) a study financed by Motorola of cell phone habits of people in eight major world cities. Talking from Birmingham, England, she said that Japan's oya yubi sedai, or thumb generation, was "the most advanced in the world."
