Why do analogous organs not provide strong evidence of a common ancestor?
Answer and explanation
Correct answer: Because their function is similar but basic structure is different
The governing concept is analogy and convergent evolution. Analogous organs carry out similar functions but arise from different basic structures and evolutionary origins, often because unrelated organisms face similar environmental demands. For example, wings of a bird and an insect serve flight but are built differently. Therefore option A is correct. Identical function and structure would suggest homology, while analogous organs are not fossils and are not restricted to humans.
