I was just sitting around and thinking about where we come from when I thought of unnatural evolution.  At first I thought the same as you…that humans will be the first to evolve unnaturally.  As I was considering the thought, I also realized that some animals are shaped by their environment and some shape the environment around them.  We are just shaping the environment around us in a more advanced way.  We will not suddenly evolve.  We will evolve at the same slow pace we always have. As we are, we will always have limits on our abilities based on our mental capacity.  Unfortunately, there will always be stupid drivers out there...I hate to say it, but there is no denying it.  Humans will not evolve unless our brains evolve and that won't happen at a rapid pace.
