Cold snap makes lizards evolve in just a few months

Have you ever considered what we learn from animals? It's one of those arguments supporting the ideology of animal protection that is often tabled by conservation advocates.

We may complain about freezing temperatures, but most cold snaps leave us little worse for the wear. That’s not the case for a common lizard living on the Texas-Mexico border, which, in just the span of a few months, underwent a dramatic genetic transformation in response to cold weather. In fact—in one of the most detailed examples of rapid evolution to date—a new study shows that just one cold snap can change the way green anoles’ muscular and nervous systems respond to temperature.
