Understand the concept of natural selection: Natural selection is a process where organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.
Identify the types of selection: There are three main types of natural selection - directional, stabilizing, and disruptive selection.
Define directional selection: Directional selection occurs when one extreme of a trait distribution is favored over the other, leading to a shift in the population's trait distribution over time.
Analyze the options: Compare each option with the definition of directional selection. Directional selection does not favor both extremes (disruptive selection) or average traits (stabilizing selection).
Conclude with the correct description: Directional selection favors individuals at one extreme of a trait distribution, leading to a change in the population's traits in that direction over time.
