Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes

Traditional ecological approaches to species evolution have frequently studied too few species, relatively small areas, and relatively short time spans. In The

“It is not only the species that change evolutionarily through interactions . . . the interactions themselves also change.” Thus states John N. Thompson in

At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in differen
