The same thing has happened with the Amur Tiger (Russia) and the easter North American Moose. Hunters hunted the large and left the smaller. Its called trophy hunting. It doesn't mean that the offspring will ALL be small but a smaller parent will on average have smaller offspring than a large parent.
