Why can the direction of natural selection change when useful traits change in an environment?
Answer and explanation
Correct answer: Because the environment determines which trait provides an advantage
Natural selection depends on the relationship between a trait and environmental conditions. A feature that improves survival in one setting may become neutral or disadvantageous after the surroundings change, while another feature may become useful. Individuals with the newly advantageous heritable trait may leave more offspring, shifting its frequency. Thus A is correct; B, C, and D deny environmental effects or biological variation.
