In a population of fish, there is substantial variation in fin length phenotype. If a fish is raised in an environment with high predator pressure, that fish will develop a smaller tail at adulthood as long tail: make them easier to catch. If a fish is raised in an environment with low predator pressure, that fish w develop a longer tail as greater length increases swimming speed and the threat of predators is low. Further, eggs from short tailed parents when raised with low predator pressure develop long tails. Eg from long tailed parents when raised with high predator pressure develop short tails. The tail length ifferences observed in this scenario are a product of evolutionary change by natural selection. True False
