What are the three types of natural selection?

In directional selection, one extreme value is favored over the other extreme or the mean. For example, faster animals outlive slower animals that are easily killed by predators or hunters. In disruptive selection, the average is selected against in a population. For example, light-colored peppered moths survive in rural areas, while dark-colored peppered moths survive in industrial areas. Medium-colored moths are easily seen in both areas, so very few of them survive.
In stabilizing selection, the average is favored. For example, human babies with average birth weight have a higher chance of surviving than babies that are too big or too small.
