Detailed explanation-1: -Wing of a butterfly and wings of birds are analogous organs as their origin is not the same but they perform similar functions. We can infer the evolutionary relationship between organisms and this is an example of convergent evolution.
Detailed explanation-2: -Insects have two pairs of wings, while bats and birds each have one pair. Insect wings lack bones, but bird and bat wings have them. Butterfly wings are covered in scales, bird wings in feathers, and bat wings with bare skin. All of these organisms have adapted to life in the air and in doing so have evolved wings.
Detailed explanation-3: -1. Do birds and insects share any structural (elements inside the wing) similarities that would suggest they are closely related taxonomically? No, the bird has bones inside of its wing the butterfly does not. They are not closely related.
Detailed explanation-4: -Analogies are similar characteristics shared by two different organisms because of convergent evolution. For example, the wing of a dove and the wing of a butterfly are analogous; the bird lineage and the insect lineage evolved wings independently of one another.
