-Coevolution;
Explanation;
-Coevolution is a change in one species that results from a change in another species that it interacts with. Coevolution occurs when two or more species reciprocally affect each other's evolution. Example; Different warbler species share the same food source. They have adapted by living in different areas of trees to reduce competition.
-Coevolution is common among organisms participating in a mutual interaction. In mutualism, both the organisms benefit from each other. When coevolution occurs among mutually benefiting species, it is called mutualistic coevolution.
