👉 In biogeography and evolutionary biology, coevolution refers to the way in which two or more species evolve together over time. This can be seen as a process where one species evolves from another species through natural selection. The terms "coevolution" and "species exchange" are often used interchangeably. For example, consider a pair of trees that have been sharing habitat for many years. Over time, the two trees may have evolved to share similar traits such as leaf shape or fruit size
