- Bmigration of members of a species to different geographical areas
- Cpower of adaptation in an individual to a variety of environments
- Dadaptations due to geographical isolation.
Correct answer
A. evolution of different species from a common ancestor
Step-by-step solution
Adaptive radiation refers to evolution of different species from a common ancestor. It is the evolutionary process by which many species originate from one species in an area and radiate to different species. The mammals are adapted for different mode of life i.e., they show Adaptive radiation. They can be aerial (bat), aquatic(whale and dolphins), burrowing or fossorial (rat), cursorial (horse), or arboreal (monkey). The adaptive radiation is also known as Divergent evolution.
