== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.

A homologous structure that is greatly reduced in size is known as a vestigial structure. These structures are remnants of organs or body parts that had a function in ancestors but are no longer used in modern organisms. Examples include the human appendix and the hip bones in whales.

homologous
The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.http://scienceline.ucsb.edu/getkey.php?key=3246
I learned about homologous and heterozygous structures in Biology.
A structure with similar shape but a different use
Two samples are said to homologous, in this context, when they are both very similar in structure and shape and more than likely function.
