Scientists who believe in evolution have chosen to boycott state Board of Education hearings on how the theory should be treated in Kansas public schools, leaving the stage clear for advocates of Intelligent Design. Strange. I thought scientists were supposed to be the open-minded ones, who examined all the evidence. Instead, like children who don’t get their way, they have taken their ball and gone home. Could it be they are unsure whether their theory can withstand a challenge in the arena of ideas?
