A person's arm and a whale's flipper.

If you take a look at the skeleton of an arm and a flipper, you'll see that they are very similar in structure.

C. arm and whale flipper are homologous because they have similar bone structure that shows a similar evolutionary origin ... but they have different forms and functions today after they have changed according to environmental needs
