Which of the following is REQUIRED for the process of evolution by natural selection to occur? These mutations were beneficial to many semiaquatic animals because the increased surface area from the webbing allowed for more swimming propulsion and swimming efficiency, especially in surface swimmers. Recall from our classes on molecular evolution that some proteins evolve more rapidly than others.
