 On this interpretation, the prey choice strategy as a whole (i.e. not, for example, the Ache’s specific, locally appropriate set of prey choices, but the general human prey choice strategy of which they are a manifestation) is presumed for heuristic purposes to be an adaptation to certain conditions in the past that led to that strategy being selected for; i.e. the selection conditions for the strategy. Supposing that it is reasonable to take behavioral strategies as such to be able to be adaptations (see the later discussion in section 4) the selection conditions of a given behavioral strategy will usually include the response conditions (because presumably it takes the production of overt behavior in order for selection to act on a behavioral strategy) but possibly also features of the larger context which made it highly adaptive to respond in that way to those response conditions. In other words, in the prey choice case, profitabilities, prey densities and search time availability would presumably have been among the selection conditions of a prey choice strategy (presuming it is an adaptation). But so would larger details about the environment not explicitly included in these models, such as the limits on human capacity which determine which prey are accessible in that environment, the ecology which determines which prey are in the environment, and so on. On this interpretation, therefore, HBEs are interested in identifying the selection conditions of human behavioral strategies; this parallels standard interpretations of non-human behavioral ecology described earlier.
