COEVOLUTION

Coevolution is a process where two or more species reciprocally affect each other's evolution through natural selection. It occurs when two or more species adapt to each other's traits and evolve together. This process often leads to close relationships between the coevolving species. For example, flowers and their pollinators, predators and prey, and parasites and their hosts typically show patterns of coevolution as they evolve to better adapt to each other.

Coevolution can affect the morphology, physiology, behavior, and life history of both the interacting species. It can result in arms races, where each species evolves new defenses and countermeasures to overcome the other's adaptations. Coevolution can also lead to mutualistic relationships between species, where each species benefits from the interaction.

Coevolution is an important driver of biodiversity and ecological relationships. It helps to shape the structure and dynamics of ecosystems, and can have implications for conservation and management of species.
