Why are analogous organs not considered strong evidence of common ancestry?
Answer and explanation
Correct answer: Because they may arise from different origins for similar functions
The governing idea is the distinction between analogy and homology. Analogous organs perform similar functions, but their developmental origin and basic structural plan can be different because similar environmental demands can produce similar adaptations independently. Therefore option A is correct. Option B is false because these organs are functional; C describes homology rather than analogy, and D is false because analogous organs occur in living organisms too.
