Homologous Structures. A homologous structure is an organ, system, or body part that shares a common ancestry in multiple organisms. This definition is found in evolutionary biology, and uses the meaning of having a similar structure or origin.omologous Structures.

Homologous structures are body parts that are alike because the species in question share a common ancestor. These structures may serve the same or different functions.For example, the wing of a bird and the arm of a human serve very different functions, but are considered homologous structures because of the evolutionary relationship between birds and humans.tructures that are embryologically similar, but have different functions, are called homologous structures. Though these animals look different, a comparison of homologous structures indicates that they are quite similar. This suggests that these animals evolved from a common ancestor.   by: Lameace[=.
