Final answer:
The correct answer is c. Species with less variation are more likely to survive environmental change. Natural selection favors species with more variation, as it increases the chances of individuals having traits that are well-suited to survive in changing environments.
Step-by-step explanation:
The correct answer is c. Species with less variation are more likely to survive environmental change. This statement is not a principle of natural selection. In fact, natural selection favors species with more variation, as it increases the chances of individuals having traits that are well-suited to survive in changing environments. The other options, a. More offspring are produced than will survive to reproduce and b. A trait that makes an organism more fit tends to be passed on to offspring, are principles of natural selection.
