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 ...
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 ...
In biology, co-adaptation is the process by which two or more species, genes or phenotypic traits undergo adaptation as a pair or group. This occurs when two or more interacting characteristics undergo natural selection together in response to the same selective pressure or when selective pressures alter one characteristic and consecutively alter the interactive characteristic.
Hummingbirds and sunbirds, two nectarivorous bird lineages in the New and Old Worlds have parallelly evolved a suite of specialized behavioral and anatomical traits. These traits (bill shape, digestive enzymes, and flight) allow the birds to optimally fit the flower-feeding-and-pollination ecological niche they occupy, which is shaped by the birds' suites of parallel traits.
It is rare for school shooters to be female, according to the data and experts who study such events.. In fact, the percentage of people who have perpetrated mass shootings who are female is in ...
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 .
