Butterfly scientist expect to trace the workings of evolution from the folds of a molecule to the breathd of a continent. They have been saying for years that the tale of evolution is written on the wings of a butterfly. Now, they're beginning to decipher it. Paul Brakefield is a world authority on spots. His questions consist of what genes change the spots' size? or do different spots evolve seperately in concert?Brakefield argues that butterfly wings, particularly their freckels, offer science a rare opportunity.They're good for experiments in an unusually wide range of scientific disciplines, so researchers can combine insights and deepen their understanding of how evolution works. The question Paul has yet to ask is what sports ''wow'' the opposite sex?
