Related to coevolution: antagonistic coevolution
The process by which two or more interacting species evolve together, each changing as a result of changes in the other or others. It occurs, for example, between predators and prey and between insects and the flowers that they pollinate.
co′e·volve′ (-ĭ-vŏlv′) v.
(Biology) the evolution of complementary adaptations in two or more species of organisms because of a special relationship that exists between them, as in insect-pollinated plants and their insect pollinators
co•ev•o•lu•tion(ˌkoʊ ɛv əˈlu ʃən; esp. Brit. -i və-)
evolution involving a series of reciprocal changes in two or more noninterbreeding populations that have a close ecological relationship and act as agents of natural selection for each other, as the adaptations of a predator for pursuing and of its prey for fleeing.
The evolution of two or more species that are dependent on one another, with each species adapting to changes in the other. The development of flowering plants and insects such as bees and butterflies that pollinate them is an example of coevolution.
