A group of iguanas living on a beach have substantial variation in their scale thickness phenotype and this characteristic is heritable. A tsunami hits the beach and kills a large number of the iguanas. After the tsunami, the proportion of thin scaled iguanas in the population is significantly higher than before the tsunami. Scale thickness is not associated with ability to survive a tsunami. Select the answer that best describes how this population will change from generation to generation assuming that the survivors of the tsunami reproduce. This population will evolve from generation to generation and will not be better adapted to its environment as a result. This population will experience random change but will not evolve from generation to generation. This population will experience evolution by natural selection from generation to generation because of the tsunami. This population will experience random change from generation to generation and will be better adapted to its environment as a result.
