Homologous structures are body structures that share a common origin, the degree at which these structures resemble each other can be used to infer the closeness of evolutionary relatedness.

-A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. It's when very different animals have bones that appear very similar in form or function and seem to be related. For example; the flipper of a dolphin and the arm of a koala.
