A species оf fish cаn hаve cоlоrs rаnging from light to dark, depending on their genotype. At first, the fish in a lake are mostly light-colored. However, the water gets darkened by pollution, so darker fish are now better at hiding from predators. Does this situation meet the requirements for natural selection? In your explanation, say which requirements it meets or does not meet (2-3 sentences, 3 pts.) Someone claims: "Pollution makes fish mutate in order to blend in. When a fish mutates to adapt, it passes that mutation down to its offspring." That claim is FALSE! Explain what is wrong with it, using the terms selection, mutation, random, and non-random correctly in your answer. (3 pts)
