In evolution, as in all areas of science, our knowledge is incomplete. But the entire success of the scientific enterprise has depended on an insistence that these gaps be filled by natural explanations, logically derived from confirmable evidence. Because "intelligent design" theories are based on supernatural explanations, they can have nothing to do with science.
I ask you to forgive me for not fulfilling some hopes of those people who believed that we would be able to jump from the totalitarian past into a bright, rich and civilized future in one go.
