A population of green iguanas lived on a tropical island. Originally, most of the iguanas had feet without webbing between their toes and a long round tail. A few iguanas had webbed feet and a short, flat tail. As the years passed, the island became smaller and smaller because of flooding. Even the land areas were dotted with ponds and pools. The iguanas had a hard time finding the food they normally ate. To survive, the iguanas had to swim from island to island to find food. How would you expect the iguanas to look many years after the island flooded and food became harder to find? A) The iguanas will look the same but there will be less of them. B) There would be more iguanas with webbed feet and flat tails. C) There would be fewer iguanas with webbed feet. D) The iguanas would no longer be green.
