Homologous structures

GetAttachment (8)

 

Homologous structures are structures that often have different functions but are structurally similar because of common ancestry.  For example, the bones in the forelimbs of vertebrates are homologous, even though they can be used for many things, such as running, flying, or swimming. The limb of the dog and the limb of the human in the picture above are homologous structures.
