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.

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
