In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution .
A commonly used example of mutualism in mosaic coevolution is that of the plant and pollinator.Anderson and Johnson studied the relationship between the length of the proboscis of the long-tongued fly (P. ganglbaueri) and the corolla tube length of Zaluzianskya microsiphon, a flowering plant endemic to South Africa.

Cospeciation is a form of coevolution in which the speciation of one ... However, if a speciation event occurs in the host species, the parasites will no longer be ...
Host–parasite coevolution is a special case of coevolution, where a host and a parasite continually adapt to each other. This can create an evolutionary arms race between them. A more benign possibility is of an evolutionary trade-off between transmission and virulence in the parasite, as if it kills its host too quickly, the parasite will ...
Coevolution occurs when each species in a relationship imposes evolutionary selection on the other(s). Examples could include mutualisms or predator-prey systems. The traditional view of plant–insect, host–parasite, and other tightly associated species, explained by Ehrlich and Raven (1964), defines coevolution as the primary mechanism for ...
These changes in the second species then, in turn, cause new adaptations in the first species. This cycle of selection and response is called coevolution. [192] An example is the production of tetrodotoxin in the rough-skinned newt and the evolution of tetrodotoxin resistance in its predator, the common garter snake.
One example of an evolutionary arms race is in sexual conflict between the sexes, often described with the term Fisherian runaway. Thierry Lodé [ 2 ] emphasized the role of such antagonistic interactions in evolution leading to character displacements and antagonistic coevolution .
In evolution, cooperation is the process where groups of organisms work or act together for common or mutual benefits. It is commonly defined as any adaptation that has evolved, at least in part, to increase the reproductive success of the actor's social partners. [1]
