Word Origin and History for coevolution
Online Etymology Dictionary, © 2010 Douglas Harper
- The evolution of two or more species that interact closely with one another, with each species adapting to changes in the other. The mutually beneficial development of flowering plants and insects such as bees and butterflies that pollinate them is an example of coevolution, as is the mutually antagonistic development of prey and predator species in which defensive adaptations in the one are matched by counteradaptations in the other aimed at neutralizing or overcoming them.
