Difficulty: 8/10 | 🟢 Free

The Question

The book lungs of a scorpion and the lungs of a blue whale both serve to maximize the surface area for gaseous exchange. Which of the following statements accurately characterizes the evolutionary relationship and embryonic origin of these structures?

Options

  • A.

    They are analogous organs representing convergent evolution; book lungs arise from the ectoderm while whale lungs arise from the endoderm.

  • B.

    They are homologous organs representing divergent evolution; both structures arise from the endodermal lining of the embryonic gut.

  • C.

    They are analogous organs representing convergent evolution; both structures arise from the ectodermal integument to optimize the surface area to volume ratio.

  • D.

    They are homologous organs representing convergent evolution; book lungs arise from the mesoderm while whale lungs arise from the endoderm.

Why This Question Is Tricky

Common Mistakes

Conceptual Pivot: Integrating cross-chapter knowledge of Evolutionary Biology (Homology vs.

Analogy) and Animal Embryology (Germ layer derivatives).

The common misconception is assuming that all internal respiratory organs share the same embryonic germ layer (endoderm) due to their similar internal placement and function, failing to recognize that arthropod respiratory structures are actually ectodermal invaginations.
