The coordinated evolution of two or more species that interact and exert selective pressures on each other that can cause each species to undergo associated adaptations. Also see evolution and natural [..]

[L. co, together + e-, out + volvere, to roll] The mutual influence on the evolution of two different species interacting with each other and reciprocally influencing each other's adaptations.

also co-evolution, 1965, from co- + evolution; supposedly introduced by Paul Ehrlich and Peter Raven in a study of the relationship between caterpillars and plants.

interactions between species that impact how both evolve. Examples: bees and plants needing pollination; the cleaner fish and the whale shark.

The influence that two ecologically-interacting species have on each other, wherein each species responds to selection imposed by the other; a history of joint divergence of ecologically associated sp [..]

(com + evolution; evolving together) (coadaptation) Reciprocal and interactive evolutionary change in two or more species living in the same area.

The joint evolution of two species, with each responding to selection imposed by the other.

the evolution of two or more interdependent species, each adapting to changes in the other. It occurs, for example, between predators and prey and between insects and the flowers that they pollinate.

Coevolution is the evolution in two or more species in which the evolutionary changes of each species influence the evolution of the other species. In other words, each species exerts selection pressu [..]

An evolutionary change in a trait of individuals of one population in response to a trait of individuals of a second population, followed by an evolutionary response of the second population to a chan [..]

a reciprocal genetic response of two interacting species through time

Two or more populations are evolved at the same time. Often the separate populations compete against each other.

Strictly, the joint evolution of two (or more) ecologically interacting species, each of which evolves in response to selection imposed by the other. Sometimes used loosely to refer to evolution of one species caused by its interaction with another, or simply to a history of joint divergence of ecologically associated species.

Changes in the genotypes of two or more species that are a direct consequence of the species’ interaction with one another. Coevolution can occur among mutualists and host--parasite pairs, as well as [..]

(ecology) The evolution of organisms of two or more species in which each adapts to changes in the other
