We know that the similarities of sharks and whales are because of convergent evolution because of the following reasons:
- Convergent evolution can be described by the presence of analogous organs.
- This is depicted when two organisms that do not have a common ancestor evolve organs with similar functions.
- Similar external stimuli, similar habitats, and mutations are some of the causes of convergent evolution.
- Sharks and whales belong to the classes Chondrichthyes and Mammalia respectively thus they have no common ancestor.
- Both live in oceans and have to face water currents thus both developed a streamlined body.
