I’m often asked what I do for a living. My answer, that I am a professor at the University of Kentucky, inevitably prompts a second question: “What do you teach?” Responding to such a question should be easy and invite polite conversation, but I usually brace for a negative reaction. At least half the time the person flinches with disapproval when I answer “evolution,” and often the conversation simply terminates once the “e-word” has been spoken. Occasionally, someone will retort: “But there is no evidence for evolution.” Or insist: “It’s just a theory, so why teach it?”
At this point I should walk away, but the educator in me can’t. I generally take the bait, explaining that evolution is an established fact and the foundation of all biology. If in a feisty mood, I’ll leave them with this caution: the fewer who understand evolution, the more who will die. Sometimes, when a person is still keen to prove me wrong, I’m more than happy to share with him an avalanche of evidence demonstrating I’m not.
Some colleagues ask why I bother, as if I’m the one who’s the provocateur. I remind them that evolution is the foundation of our science, and we simply can’t shy away from explaining it. We don’t avoid using the “g-word” when talking about gravitational theory, nor do we avoid the “c-word” when talking about cell theory. So why avoid talking about evolution, let alone defending it? After all, as a biologist, the mission of advancing evolution education is the most important aspect of my job.
