Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Analogous organs
Concept:

When unrelated lineages face similar environmental pressures, they may evolve similar adaptations independently.

Solution:

  • Structures that serve the same purpose (e.g., flight, swimming) but have entirely different evolutionary origins and internal anatomy are called Analogous organs.
  • They are the direct result of convergent evolution. Examples include insect wings vs. bird wings, or the streamlined shape of sharks (fish) and dolphins (mammals).


Why other options are incorrect:

  • Homologous organs: Similar structural origin, but often adapted for different functions.
  • Convergent/Divergent: These terms describe the evolutionary process, while "analogous/homologous" strictly name the organs themselves.

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.
