Adaptation to a new environment allows cooperators to purge cheaters stochastically.
Cooperation via production of common goods is found in diverse life forms ranging from viruses to social animals. However, natural selection predicts a "tragedy of the commons": Cheaters, benefiting from without producing costly common goods, are more fit than cooperators and should destroy cooperation. In an attempt to discover novel mechanisms of cheater control, we eliminated known ones usin...

Less studied is the benefit from sexual selection in toto, that is, when intra- and intersexual selection are both present and able to affect females directly and indirectly. Here an upper bound for the net ...
