Detailed explanation-1: -Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous, but not homologous.

Detailed explanation-2: -Bird and bat wings are called analogous because they have separate evolutionary Origins but they both perform a similar function which is a key role in flight. Analogous organs are the result of convergent evolution.

Detailed explanation-3: -The wings of birds and butterflies have the same function-they enable the organisms to fly.

Detailed explanation-4: -The wing of a bird and a butterfly wing are analogous structures, whereby the organisms do not share a common ancestral history. Birds and butterflies adapted to their changing environments and converged for a common function-flight-the only similar evolutionary process observed in both species.

Detailed explanation-5: -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.
