The offspring resemble their parents (i.e. they look like lizards from their home island). Does this support or contradict the idea that evolution has occurred? Group of answer choices a. support because it implies that a genetic change has occurred b. contradict because the lizards were removed from the islands c. support because the phenotype matches the environment d. contradict because the environment is different in the lab e. support because it is a major change in phenotypearrow_forward
