Less Squirrelly Squirels

Do you think that, by systematically running over squirrels that try to out-maneuver automobiles, we are breeding squirrels that can distinguish between autos and predators? If so, then, given the short length of a squirrel generation, shouldn't we have seen significant improvement by now?

    I've thought that we'd've (a double contraction; gaze ye in awe upon it) evolved squirrels that could time traffic by now. You see it every once in a while, a squirrel who will wait for a car to go by, then take off, but it sure doesn't seem to be the norm. Even with single-year generation times, evolution is a slow, slow process.

  2. Nice double contraction. I do indeed gaze in awe.

  3. Ooo, I know! Actually, we are only hitting the squirrels who are old and slow. Therefore, they have already bred and selection cannot occur because getting hit by cars does not impact their reproductive fitness.
