“ The many meanings of 'evolution' are frequently exploited by Darwinists to distract their critics. Eugenie Scott recommends: 'Define evolution as an issue of the history of the planet: as the way we try to understand change through time. The present is different from the past. Evolution happened, there is no debate within science as to whether it happened, and so on... I have used this approach at the college level.' Of course, no college student—indeed, no grade-school dropout— doubts that 'the present is different from the past.' Once Scott gets them nodding in agreement, she gradually introduces them to 'The Big Idea' that all species—including monkeys and humans—are related through descent from a common ancestor... This tactic is called 'equivocation'—changing the meaning of a term in the middle of an argument. ”
