Abstract
Background: A major cornerstone of evolutionary biology theory is the explanation of the
emergence of cooperation in communities of selfish individuals. There is an unexplained tendency
in the plant and animal world with examples from alpine plants, worms, fish, mole-rats, monkeys
and humans for cooperation to flourish where the environment is more adverse (harsher) or
more unpredictable.
Results: Using mathematical arguments and computer simulations we show that in more adverse
environments individuals perceive their resources to be more unpredictable, and that this
unpredictability favours cooperation. First we show analytically that in a more adverse environment
