What is the difference between homologous and analogous structures?

Explanation

Homologous structures are body parts that have a similar internal structure and origin but perform different functions, showing evidence of a common ancestor. For example, the forelimbs of humans, bats, and whales share the same bone pattern but serve different purposes. In contrast, analogous structures have different internal structures but perform similar functions, like the wings of birds and insects, which evolved separately. Therefore, the correct statement is that homologous structures have similar structure but different functions, indicating divergent evolution among related species.
