What is the role of environment in natural selection?
Answer and explanation
Correct answer: It determines which traits are useful in that environment
Natural selection operates through the interaction between inherited variation and environmental conditions such as food availability, temperature, disease, and predators. A trait that improves survival or reproduction in one environment may be less useful in another. Therefore, option A is correct: the environment influences which existing variations are advantageous. It does not make organisms identical, erase genes, or provide immortality, so B, C, and D are incorrect.
