Individuals do not evolve; populations of organisms do. Punctuated equilibrium is when there is a long period with no change, followed by a huge, quick change. When a host evolves a defence against a parasite, then the parasite may evolve counter-adaptations to its host's defence. Over time, species evolve through natural selection in response to each other. This is called coevolution. The host on the other hand keeps on evolving its defense systems in the body to get rid of the parasite. Examples of how to use "coevolution" in a sentence from the Cambridge Dictionary Labs | Meaning, pronunciation, translations and examples Observing parallel host and parasite phylogenies is evidence of cospeciation. Define coevolution. An oft-cited example is that of insect pollinators and flowering plants. These changes can add up, resulting in large changes. an evolutionary change in the chemical defenses of a plant, might over time select for change in the morphology or digestive system of an herbivore that eats the plant *selection in turn might affect the evolution of the plant, such that it increases its chemical defneses. Some examples of coevolution include: Yucca moths and yucca plants Yucca flowers are a certain shape so only that tiny moth can pollinate them. In biology, coevolution is the change of a biological object triggered by the change of a related object. An example of divergent evolution in finches.

Divergent evolution occurs when two different species share a common ancestor but have different characteristics from one another. Multiple characteristics have been developed by the flowers to better suit the birds such as coloration to attract the birds, shape to fit the birds beak, and an especially sweet, high energy, nectar. Coevolution Definition. n. The process by which two or more interacting species evolve together, each changing as a result of changes in the other or others.
