Answer :
Final answer:
Homologous structures are similar anatomical features in different species indicating a common ancestor with potential functional differences.
Explanation:
Homologous structures are similar anatomical structures found in different species that suggest a common ancestor. These structures have the same embryological origin, but may have different functions in descendants due to evolutionary adaptations. For example, the forelimbs of mammals share a basic bone pattern inherited from a common ancestor, even though they serve different purposes in different species.
