Answer;
-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.
They both are mechanisms by which new species arise.
Hope this helps! ;)
