Question #46447
The Question
Adaptive radiation relies on the principle of divergent evolution, where varying environmental selection pressures act upon a common ancestral blueprint. Which of the following pairs of structures fails to demonstrate the anatomical homology resulting from this evolutionary process?
Options
- A.
Forelimbs of Pteropus (Bat) and Balaenoptera (Whale)
- B.
Axillary bud modifications in Bougainvillea and Cucurbita
- C.
Underground storage structures in Ipomoea batatas (Sweet potato) and Solanum tuberosum (Potato)
- D.
Structural organization of vertebrate hearts and brains

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Linking 'Adaptive Radiation' exclusively to 'Divergent Evolution' and 'Homology'.
The trap tests the student's ability to identify analogous structures (convergent evolution) hidden behind scientific nomenclature.
Students often fail to distinguish between environmental pressure mimics (analogy) and true homologous radiations when presented with functional similarities like underground storage.
