Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Analogous organs
Concept:

Different evolutionary lineages can independently develop similar adaptations in response to similar environmental challenges.

Solution:

  • Structures that look similar and perform the same functions but have completely different internal anatomy and embryonic origins are called Analogous organs.
  • For example, the wing of a bat (mammal) and the wing of a butterfly (insect) are both used for flight, but their internal structures are unrelated.
  • This represents convergent evolution.


Why other options are incorrect:

  • Homologous organs: Have the same internal structure but often different functions (divergent evolution).
  • Symmetry: Refers to body plans, not specific structural adaptations.

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.
