Why are insect wings and bird wings called analogous organs?
Answer and explanation
Correct answer: Because both help in flight but have different origin
Insect wings and bird wings perform the same broad function—flight—but they are built from different structures and arose independently in these unrelated animal groups. This combination of similar function and different origin is the definition of analogous organs and reflects convergent evolution. Option B is therefore correct. Similar basic structure would indicate homology, while these wings are neither fossils nor vestigial organs.
