Which of these statements best sums up evolution? a. rapid change in species’ habits and features b. punctuated change in a population c. change in a population through new species being made d. change in a population through genetic variation over time

D. change in a population through genetic variation over time

Evolution is the change in characteristic  of a species over generations or with respect to time and it relies on the process of natural selection. Evolution relies on the process of genetic variation which is necessary to bring phenotypic changes which facilitate the survival of the organisms in unfavourable environmental conditions this is known as adaptation.
