A population of butterflies used to have smalI, medium, and large individuals, but several years ago a non-native bird was introduced to the butterfly's habitat. It eats butterflies but only those that are medium size. Eventually, medium-sized butterflies became rare. This is an example of: Disruptive selection Directional selection Stabilizing selection Artificial selection
