Quizplus · Accepted Answer

When previous adaptations in a species are no longer useful in a changed environment, natural selection favors individuals with different traits that are more suited to the new environment. This leads to the selection of a different form or adaptation in the species. Artificial selection is not relevant in this context as it involves human intervention rather than natural forces. Fitness may be observed, but it is not the primary result of the process described here. Thus, option D is incorrect.
