WebSep 15, 2016 · Foraging theory can be used to explain two important phenomena, how and why organisms choose particular foodstuffs (Optimal Diet Theory) and how long individuals will remain in resource patches before seeking others (marginal value theorem). The theories are analytical and produce explicit, quantitative predictions. WebHere, we examine the relevance of optimal diet theory to humans. We will focus on a re-cent claim that this theory predicts that the mongongo nut should not be a preferred food of the !Kung San (Hawkes and O'Connell 1981). Our intention, however, is not to sim-ply criticize this one study, but to pinpoint general reasons why simple optimal diet ...
