Detailed explanation-1: -The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.

Detailed explanation-2: -Mutation is the random part, but adaptation and selection pressure are the non-random parts.

Detailed explanation-3: -The result of natural selection is adaptation to the prevailing environment. Thus, natural selection is non-random. Nor is it progressive i.e. it doesn’t lead towards a predetermined goal.

Detailed explanation-4: -Answer and Explanation: This statement is false. Natural selection is a process in which organisms evolve to become better adapted to their environments. Although the genetic variations upon which natural selection acts do arise from random mutations, natural selection is not random.

Detailed explanation-5: -Natural selection is random because no individuals are eliminated from reproducing due to different environments. Evolution occurs in individuals, not populations. In an evolutionary sense, fitness refers to an organism’s contribution to the next generation’s gene pool.
