Question #46436
The Question
Analyze the following statements regarding evolutionary adaptations and select the INCORRECT statement:
Options
- A.
Sweet potato (Ipomoea batatas) and potato (Solanum tuberosum) represent analogous structures that evolved via convergent evolution.
- B.
The rapid emergence of pesticide-resistant insects is an example of evolution by anthropogenic action, driven by directional selection.
- C.
Both the development of storage tubers in sweet potato and pesticide resistance in insects represent morphological convergence driven by similar habitat pressures.
- D.
While analogous organs arise due to similar environmental challenges, pesticide resistance is a biochemical adaptation selected from pre-existing genetic variations.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Distinguishing between morphological convergence (analogous organs) and physiological/biochemical adaptation (pesticide resistance).
Students often misclassify any shared adaptive trait as 'morphological convergence', failing to recognize that pesticide resistance is a metabolic response driven by directional selection, not a gross structural modification like a tuber.
