| founder effect | process by which a population acquires a very different gene pool from its parent population because it descends from a few ancestors (often the result of isolation) |
| adaptive radiation | process by which several populations evolve from a parent population, adapted to different ecological niches, Darwins finches are an example |
| coevolution | the process by which two or more species evolve in response to each other |
| gradualism | process by which a species evolve at a continuous, slow steady pace |
