The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge, is called:

1. Convergent evolution
2. Non-random evolution
3. Adaptive radiation
4. Natural selection

Correct answer: Convergent evolution

Solution

Convergent evolution occurs when organisms with different evolutionary backgrounds independently develop similar adaptations because they face similar environmental challenges. The similarity is due to comparable selective pressures, not shared recent ancestry.
