not benefit energy, but would benefit other needs. The goals and currencies of humans can often change due to behavioral flexibility. These changes can occur over a long time, over a season or during a hunt. Optimal Foraging Theory must therefore be more complex and introduces more goals and constraints to match the complex decision-making processes employed by humans. The decision-making processes can furthermore be influenced by long-term and short-term experiences and these experiences can then further influence others. But Optimal Foraging Theory has helped Archaeology in generating new interpretations of patterns in the archaeological record and thinking about human behaviours in greater detail. Optimal Foraging Theory have also given Archaeology a better insight into the cost and benefits of different resources.
