검증된 단계별 안내1
Understand the concept of natural selection: Natural selection is the process by which organisms with traits better suited to their environment are more likely to survive and reproduce.
Review the types of natural selection: Directional selection, stabilizing selection, balancing selection, and disruptive selection are different patterns of how traits are favored in populations.
Define directional selection: Directional selection occurs when one extreme variation of a trait is favored over other variations, leading to a shift in the population's trait distribution toward that extreme.
Compare with other types of selection: Stabilizing selection favors intermediate traits, balancing selection maintains genetic diversity, and disruptive selection favors both extremes of a trait over intermediate forms.
Conclude that the correct type of natural selection described in the problem is directional selection, as it specifically favors one extreme variation of a trait.
