Coadaptation

Coadaptation is the process where two or more species of organisms adapt to their environment together. This term was coined by biologist Ernst Mayer and refers to the simultaneous change of two or more organisms in response to the same environmental factor. This can happen, for example, when two species of plants or animals compete for resources in the same environment. As a result, both species can adapt to the same conditions, which helps them survive and thrive.

Coadaptation can be both positive and negative. For example, two predators hunting the same type of prey may develop different strategies to catch more prey. One can hunt during the day, and the other at night. This way they work in different parts of the day and use different hunting tactics, allowing both to survive. However, if two species have opposing needs for some resources, they may begin to compete with each other and weaken their ability to survive.

There are several theories and mechanisms of co-adaptation. One is the “fear of extirpation” effect, which implies that species adapt to competitors to avoid extirpation. Another theory is mutual utility, which suggests that different organisms can offer assistance to each other, such as protection from predators or increasing their numbers.

For example, goats and wolves have co-adapted in the Alaska ecosystem, where they coexisted for many years. Each type has developed optimal
