| In Britain the loss of these kinds of defenses makes the birds once again targets for attack by cuckoos, thereby continuing the process of coevolutionary alternation among hosts. |
| These reciprocal evolutionary changes in interacting species are called coevolutionary processes, one of the primary methods by which biological communities are organized. |
| Should a species be reduced to a few populations, the geographic mosaic of diverse adaptations that fuels the coevolutionary process is diminished. |
| Such studies, however, require that intact biological communities are preserved as precious natural laboratories for understanding the coevolutionary process. |
| In the process called coevolutionary alternation, one species coevolves with several other species by shifting among the species with which it interacts over many generations. |
| The beginnings of animal domestication involved a protracted coevolutionary process with multiple stages along different pathways. |
