« Robert Foley, […] has long emphasized the relationship between resource distribution and sexual dynamics. For example, if crucial resources are clumped in rich, predictable local patches (like a salmon run), then one or a few males, by seizing control of resources, can thereby ensure sexual access to the women needing those resources. This resource distribution opens the door to polygyny. In contrast, if resources are pepper-potted unpredictably throughout the environment, women will scatter, chasing those resources, closing the door to polygynous strategies. »
