Detailed explanation-1: -Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.
Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’
Detailed explanation-3: -The four propositions underlying Darwin’s theory of evolution through natural selection are: (1) more individuals are produced than can survive; (2) there is therefore a struggle for existence; (3) individuals within a species show variation; and (4) offspring tend to inherit their parents’ characters.
Detailed explanation-4: -Darwin referred to this process, in which groups of organisms change in their heritable traits over generations, as “descent with modification."
Detailed explanation-5: -Darwin used multiple lines of evidence to support his theory of evolution by natural selection–fossil evidence, biogeographical evidence, and anatomical evidence.
