Think of this as "enforced Darwinism"!Right, after several generations we will have high-speed, high-maneuverability ducks with armored protection on their skulls.. After that, they will see that we can do nothing to harm them, and will start stealing food from our homes
Not to rain on Darwin's parade, but, um, the death of the unfit does not mean that the survivors have automagically improved. They're still the same ol' critters they were before the unfit died off.
(It might can be argued that the improvement came to the fit population _before_ the unfit died off, but it can just as equally be argued that the entire population originally started out as fit, and then the sub-population degenerated into the unfit. And I'm not trying to argue one side or the other; I'm just pointing out that there's a disconnect in the thinking that the extinction of the less-fit automatically means the survivors have seen some sort of improvement.)
