What is the correct basis of Darwin's natural selection?
Answer and explanation
Correct answer: Organisms with useful variations survive and reproduce more
Darwin’s natural selection is based on heritable variation, competition, and differential survival and reproduction. Individuals in a population differ, and a variation that improves survival or reproduction can give its bearer an advantage in a particular environment. Such individuals tend to leave more offspring, so the useful inherited trait becomes more common over generations. Thus, option A is correct; the other statements contradict natural selection.
