Question

Sweet potato and potato represent a certain type of evolution.

Select the correct combination of terms to explain the evolution.

1. A. Analogy, convergent (Correct answer)
2. B. Homology, divergent
3. C. Homology, convergent
4. D. Analogy, divergent

Correct Answer

Option A — Analogy, convergent

Detailed Solution & Explanation

The correct answer is Analogy, convergent.

Key Points

• Sweet potato is a root modification while potato is a stem modification, yet both store food and look alike — they are analogous (similar function, different origin).
• Analogous structures arise through convergent evolution. (Homologous structures, from a common origin, arise by divergent evolution.)
