Abstract

Much of evolution is coevolution - of parasites and hosts, predators and prey, competitors, and mutualists. Interacting species impose selection on each other, continually reshaping each other's traits and life histories. This process of reciprocal evolutionary change driven by natural selection has molded the web of life, resulting in a world that not only has millions of species but also tens of millions of interactions among those species. Coevolution shapes the web of life. Almost everywhere on earth, then, coevolved interactions have made it possible for organisms to exploit new environments, thereby fueling the further diversification of life. The result is not a world functioning as a self-sustaining unit. Rather, it is a wildly dynamic world of constantly coevolving mutualistic and antagonistic interactions. The coevolutionary process has fueled such a diversity of life and lifestyles that, at least so far, some species have made it through each of the periods of mass extinction that have occurred during our earth's history.
