Official Correct Choice:
Option A: Analogous organs
Concept:

Comparative anatomy helps classify evolutionary pathways based on structural similarities and functional adaptations.

Solution:

  • Analogous organs are structures that perform a similar function (e.g., flying) but have entirely different underlying anatomical blueprints and embryonic origins.
  • Examples include the wings of insects and the wings of birds.
  • They arise due to convergent evolution, where unrelated species adapt to similar environmental pressures.


Why other options are incorrect:

  • Homologous organs: Have the same structural origin but may perform different functions (e.g., human arm and bat wing).
  • Convergent/Divergent evolution: These are evolutionary processes, whereas the question specifically asks for the name of the organs.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
