a population of pigs lives on an island together with burrowing termites. pigs that have the longest snouts tend to survive more frequently than those with shorter snouts. over time, most of the pig population is made up of individuals that have very long snouts. this is an example of which type of selection?\ndirectional selection\ndisruptive selection\nstabilizing selection\necosystem selection

Answer

Brief Explanations:

Directional selection favors one extreme of a trait. Here, pigs with the longest snouts have a survival advantage, and over time the population shifts towards this extreme trait. Disruptive selection favors both extremes and not the intermediate. Stabilizing selection favors the intermediate form. Ecosystem selection is not a recognized type of natural - selection in this context.

Answer:

A. directional selection
