Abstract

Velik dio evolucije je koevolucija – paraziti i domaćin, predatori i plijen, kompetitori i mutualisti. Vrste koje su u interakciji jedna drugoj nameću selekciju, kontinuirano međusobno preoblikujući značajke i životnu povijest. Takav proces recipročne evolucijske promjene potaknut prirodnom selekcijom je oblikovao mrežu života, stvarajući svijet koji ima ne samo milijune vrsta, već i desetke milijuna interakcija među tim vrstama. Koevolucija oblikuje mrežu života. Gotovo svugdje na Zemlji, koevolucijske interakcije su omogućile organizmima da iskoriste nove okoliše, tako potičući daljnju diversifikaciju života. A rezultat nije svijet koji djeluje kao samoodrživa jedinica, već divlji, energičan svijet konstantno koevoluirajućih mutualističkih i antagonističkih interakcija. Koevolucijski proces je potaknuo takvu raznolikost živog svijeta i stilova života, da su neke vrste preživjele sve periode masivnih izumiranja tijekom povijesti Zemlje. Barem za sad.

Abstract (english)

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.
