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

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.

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.

The Theory of Evolution.

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity

My theory of evolution is that Darwin was adopted.
