A dog and a dolphin have similar bone structures even though one is used for running and one is used for swimming. Is this homologous, vestigial, or analogous structure example?

The bone structures of a dog and a dolphin are an example of homologous structures. Homologous structures are anatomical features that have a similar underlying structure or developmental origin, even if they have different functions in the adult organism. In this case, the dog's and dolphin's limbs both have the same basic bone structure, but they have evolved to serve different functions (running for the dog, and swimming for the dolphin). This is in contrast to analogous structures, which have similar functions but different underlying structures and developmental origins, and vestigial structures, which are reduced or non-functional versions of structures that were functional in the organism's ancestors.
