The figure below shows the skeletal structure of a seal's flipper and a monkey's arm.
The skeletal structures of the flipper and the arm are similar, even though they have different functions. Seals use their flippers for swimming, while monkeys use their arms primarily for grasping and lifting.
The seal's flipper and the monkey's arm differ in appearance. This difference is the result of
- migration
- genetic engineering
- succession
- natural selection
