Evolution makes biology make sense. And if you don't teach your students the evolutionary core of biology, you're making it harder for them.

I never say that evolution is a fact. Evolution is a theory. It's much more important than a fact, because theories explain things.

People don't show up here (at the courtroom) because they believe evolution is bad science. They show up because they believe that if they accept evolution, then they are abandoning their religious beliefs. They see it as an either/or proposition: Either evolution happened, or God loves you.

When they say 'teach the controversy' — their ringing phrase — they want us to pretend to students that scientists are arguing whether evolution took place. This argument is not taking place.

To say that evolution is sort of on the ropes is unfair to the students of Kansas.
