What is the most important difference between homologous and analogous organs?
Answer and explanation
Correct answer: Homologous have similar basic structure while analogous have similar function
The key comparison is structure versus function. Homologous organs share a similar basic structural plan, often because of common ancestry, even when their functions differ. Analogous organs perform similar functions but have different underlying structures and evolutionary origins, such as bird and insect wings. Thus option A states the essential distinction. The remaining options are biologically false or deny a well-defined difference.
