Explain divergent evolution in detail. What is the driving force behind it ?
Whales, bats, Cheetah and human (all mammals) share similarities in the pattern of bones of forelimbs. Though these forelimbs perform different functions in these animals, they have similar anatomical structure.
All of them have humerus, radius, ulna, carpals, metacarpals and phalanges in their forelimbs.
Hence, in these animals, the same structure developed along different directions due to adaptations to different needs.
This is divergent evolution and these structures are homologous. Homology indicates common ancestry. Driving force behind the divergent evolution is Adaptive Radiations in different environments to perform different function.
