In future generations, the transplanted lizard population is most likely to A) evolve shorter legs adapted for the smaller plants. B) undergo no evolutionary change. C) evolve to be able to maneuver less efficiently. D) evolve to be able to run away from predators more quickly. E) evolve even longer legs.
