Homologous+vs.+Analogous+Structures

Homologous vs. Analogous Structures Understanding the differences between homologous and analogous structures is simple:


 * **Homologous structures** are similar structures that serve a similar purpose and share a common evolutionary origin.


 * 1) An example of a homologous structure include the legs of a horse and a donkey.


 * **Analogous structures** are similar structures that also serve a similar purpose, but they do //not// share an evolutionary origin.


 * 1) An example of analogous structure includes the wings of an insect and a bat.
