Question

Quizplus · Accepted Answer

Changing environmental conditions can cause directional selection as certain traits become more advantageous and natural selection favors individuals who express those traits. This can eventually lead to a change in the overall genetic makeup of the species over time. Disruptive selection could also occur, but this would only happen if the environmental changes create two or more distinct selective pressures that favor different traits, leading to the splitting of the species into multiple subgroups. Mutation and stabilizing selection are not direct responses to environmental changes, but rather ongoing processes that can occur regardless of environmental conditions.
