Detailed explanation-1: -Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition. Accordingly, variation is present in the population. Thus, the correct answer is option E.
Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’
Detailed explanation-3: -Answer and Explanation: The correct answer is E) It requires genetic variation, results in descent with modification, and involves differential reproductive success.
Detailed explanation-4: -Therefore, the correct option is B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment will survive.
Detailed explanation-5: -Natural selection describes an individual becoming better suited to its environment; evolution describes a population becoming better suited to its environment. D. Natural selection and evolution are the same thing. The correct answer option is (B).
