One of my favourite science articles of all time, devoted to a humble amoeba species, has unparalleled implications for corporate leadership. It turns out that some amoebas evolve to free-ride on the self-sacrifice of other amoebas. In hard times the amoebas leading the migration of a colony die in order to create a stalk of dead cells on which the other amoebas can climb to get carried away by the wind to a better location. The free-rider amoebas go slower than the rest of the colony so that they would never find themselves in the self-sacrificial leading position.
Yet, eventually the free-rider amoebas get punished as evolution helps the self-sacrificing amoebas mutate and outcompete the free-riders. A small percentage of the "good amoebas" refuse to be pushed around by the free-riders and after multiple generations of reproduction the resistant strains of leader amoebas come to dominate. The researchers, who published their findings in Nature, conclude that "the presence of cheaters inevitably gives rise to cheater-resistant mutations".

This type of equilibrium is known to biologists as an Evolutionarily Stable Strategy (http://en.wikipedia.org/wiki/Evolutionarily_stable_strategy). In such settings, a given behaviour confers more advantages as it becomes rarer, so the players with the rare behaviour multiply faster and this increase in population restores the equilibrium.
