The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge is called:
Convergent evolution
Non-random evolution
Adaptive radiation
Natural selection
convergent evolution is the process where different structures or organisms with different evolutionary histories evolve for the same function and hence have similarity. This occurs because a similar habitat (common environmental challenge) results in the selection of similar adaptive features in different groups of organisms . In contrast, adaptive radiation is the process of evolution of different species in a given geographical area starting from a point and radiating to other areas .
