| Homologous Structures | Structures that are embryologically similar, but have different functions |
| Vestigial Structures | Structures that have lost their primary function through the evolutionary process |
| Reproductive Isolation | the inability of a species to breed successfully with related species due to geographical, behavioral, physiological, or genetic barriers or differences |

| Descent With Modification | A gradual process in which something changes into a different and usually more complex or better form |
