Why is evolution understood at the population level rather than at the individual level?
Answer and explanation
Correct answer: Because inherited changes accumulate in populations over generations
Evolution means a change in the inherited characteristics or allele frequencies of a population across generations. An individual can grow, learn, or acquire a change during its lifetime, but such an acquired change is not automatically inherited by offspring. When inherited variation affects survival and reproduction, its frequency may increase or decrease in the population. Therefore option A is correct; the distractors incorrectly deny individual changes, reproduction, or the timescale of evolution.
