Lacking this evidence, evolutionary proponents of selection will, like darwin, inevitably ease acceptance by appealing to the powerful analogy of artificial selection to natural selection however, without evidence for a real selector, a continuous use of metaphors should be another warning for creation scientists to begin re-evaluation.
Natural selection involves the survival and reproduction of those species which have inherited a variation which gives them an edge over others in coping with the environment the better adapted individuals survive and breed more readily. Natural selection does not act directly on genotypes: it operates on phenotypic differences among the individuals in a population evolution by natural selection is a process by which the characteristics of a population—not those of an individual—change over time.

In sum, the uses of metaphor and analogy in epistemology and philosophy in general are much the same as their uses in science analogy is a powerful mode of thought that is indispensable in the formation, development, evaluation, and exposition of theories, in philosophy as well as science.
