I wont be the one to start the argument, as I believe in both creation and evolution.

As far as deer behavior, they would all die quickly without good instincts and senses. I believe that an individual deers ability to actual learn, is probably what separates the so-so bucks from the ones that get big, old and live along time on public and "non-fenced-in" private land. Anyone can grow a big buck with high fences.
