<dim:field mdschema="dc" element="description" qualifier="abstract" lang="en">We study the influence that resource availability has on cooperation in the context of hunter-gatherer&#xd;
societies. This paper proposes a model based on archaeological and ethnographic research on resource&#xd;
stress episodes, which exposes three different cooperative regimes according to the relationship&#xd;
between resource availability in the environment and population size. The most interesting regime&#xd;
represents moderate survival stress in which individuals coordinate in an evolutionary way to increase&#xd;
the probabilities of survival and reduce the risk of failing to meet the minimum needs for survival.&#xd;
Populations self-organise in an indirect reciprocity system in which the norm that emerges is to share&#xd;
the part of the resource that is not strictly necessary for survival, thereby collectively lowering the&#xd;
chances of starving. Our findings shed further light on the emergence and evolution of cooperation in&#xd;
hunter-gatherer societies.</dim:field>
