Why is it more correct to understand evolution at the population level rather than at the individual level?
Answer and explanation
Correct answer: Because inherited changes alter trait frequencies in populations over generations
The governing concept is evolution as a change in heritable variation within a population across generations. An individual may grow, learn, or acquire a temporary characteristic, but such changes do not normally alter the population gene pool. Mutations and recombination create heritable variation, while selection, drift, and gene flow change its frequency among generations. Thus A is correct; B, C, and D confuse individual development with population evolution.
