What is the most correct reasoning for calling adaptation a result of natural selection?
Answer and explanation
Correct answer: Useful inherited traits can become more common over generations
The governing concept is differential survival and reproduction. A population contains heritable variation before selection acts. If a particular inherited trait improves survival or reproductive success in a given environment, its carriers are more likely to leave offspring. The trait can therefore increase in frequency over several generations, producing adaptation at the population level. Option A states this process; B, C, and D incorrectly invoke will, guaranteed inheritance, or no environmental effect.
