Chemisor writes: According to new research by a Swiss university, it doesn't pay to be smart. "Scientists Tadeusz Kawecki and Joep Burger at the University of Lausanne said they had discovered a negative correlation between an improvement in a fly's mental capacity and its longevity". In the experiments, eugenic methods have been applied to a population of flies, demonstrating a measurable increase in intelligence after 30 to 40 generations. The smart flies lived 50-60 days, while the stupid ones in the control population lived 80-85. "This would explain why flies, like most other animals, have hardly developed their neural capacities," the researchers said.
