Detailed explanation-1: -coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.

Detailed explanation-2: -Evolution: Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another.

Detailed explanation-3: -Coevolution refers to when two or more species have an effect upon one another. An example of this would be when predators and prey change over time due to their interactions with one another. In this instance, the prefix ‘co’ means ‘together’.

Detailed explanation-4: -Co-adaptation and coevolution, although similar in process, are not the same; co-adaptation refers to the interactions between two units, whereas co-evolution refers to their evolutionary history. Co-adaptation and its examples are often seen as evidence for co-evolution.

Detailed explanation-5: -Types of Coevolution Pairwise coevolution (or ‘specific’ coevolution) describes tight coevolutionary relationships between two species. Diffuse coevolution (or ‘guild’ coevolution) refers to reciprocal evolutionary responses between suites of species.
