Why is variation important for evolution?
Answer and explanation
Correct answer: It provides a basis for natural selection
Variation means differences among individuals of the same population. If a variation is heritable and gives an advantage in a particular environment, its carriers may survive and reproduce more successfully. Natural selection can then make that useful variation more common over generations. Therefore, option A is correct. Variation does not make organisms identical, destroy food, or stop respiration, so B, C, and D are incorrect.
