A group of alligators' snouts evolve to become shorter over time. This benefits the alligators in their environment, as this lets them move to catch prey more quickly. What pattern of natural selection is effecting the alligators?

A population of otters are pressured by their environment to not be significantly larger or smaller than the average otter. If otters are very large, they would require too much food to sustain, and if they are too small they will be too weak to compete for food. What sort of selection do these otters experience?

• Directional selection

• Disruptive selection

• Stabilizing selection
