Enumerate on convergent and divergent evolution with suitable examples in animals.

Explanation

If same structure developed along different directions due to adaptation to different needs it is called divergent evolution and results in homologous organs. Ex Thorn and tendrils of bougainvillea and cucurbita.
If different structure evolving for the same function and hence having similarities, It is called convergent evolution. It is results in analogous organ. Ex Sweet potato(Root modification) and Potato(Stem modification)
