Quizplus · Accepted Answer

Natural selection acts on populations, not individuals, to increase the frequency of traits that enhance the survival and reproduction of the population in a particular environment. Therefore, the correct choice is B) the characteristics of populations change over time. Option A is not correct because although natural selection can result in changes in the traits of individuals, the process occurs at the level of the population. Option C is not incorrect because population-level changes result in alterations in individual characteristics, but it is not the best answer. Option D is not correct because natural selection is a well-established scientific concept.
