Question

The wings of birds and butterflies have the same function—they enable the organisms to fly. Which statement can be made about the evolutionary relationship between these organisms?

Answer 1

Birds and butterflies have homologous organs, which indicate they share a common ancestor.

Answer 2

Because their wings are considerably anatomically different, this would be a case of convergent evolution with the wings being seperately evolved as an analogous rather than homologous structure after their divergence from a common ancestor. This would mean that birds and butterflies are probably not closely related.
