I wonder why they still do it. We create an artificial environment for them. Artificially available food, water and light. A stable cycle that's typical and based on a time stamp rather then sun rotation, at least I assume for people with beardies who still brumate that they aren't mimicking seasonal change. Why do they still do it, I wonder? If they're having the same, say, 12 hour cycle and the temps/humidity/food availability/water remain unchanged, why do they still feel the biological imperative to brumate. It's really intriguing to me from a biological stand-point. What inside them has remained unchanged even through breeding and semi-domestication (since they could feasibly still survive in the wild because their instincts remain functional for that)? I can't help it! The science! The science!!!! SCCIIEEENNNCCCCEEEE!!! *twitch twitch*
