Step-by-step solution
Mechanism Definition and Examples Adaptive radiation The process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography (habitats) is called adaptive radiation. Example: Darwin finches Divergent evolution The structures in different organisms which have similarities in their anatomy or basic plan but serve different functions are known as homologous structures. This is an example of divergent evolution. Example: Bones of forelimbs in
