Q. The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge is called
A) Natural selection
B) Convergent evolution
C) Non-random evolution
D) Adaptive radiation
Explanation
[Solution from source] When unrelated lineages facing similar environments evolve similar adaptations, the process is convergent evolution, which produces analogous structures. Adaptive radiation is the opposite pattern, where one ancestor gives rise to many differently adapted forms. Answer (2).
