If two organisms have organs with similar basic structure, what may this indicate?
Answer and explanation
Correct answer: Relationship through a common ancestor
The governing concept is homology. Organs that share a similar basic structural plan, even when they perform different functions, are called homologous organs. Their structural similarity is best explained by inheritance from a common evolutionary ancestor, followed by modification in different lineages. Thus option A is correct. Food, body colour, and the presence of genetic material do not determine whether organs have a shared structural origin.
