 However, HBEs can get around this problem, by pointing out that local patterns of overt behavior are manifestations of more general strategies; differences in the environment cause the manifestations of different elements of these complex behavioral dispositions humans possess. For example, the patterns of foraging behavior of the Ache people in the Paraguay rain forest (Hill and Hurtado, 1996) and the Inuit in the Arctic (Smith, 1991) are very different, and the genetic differences between these groups are insufficient to explain them. However, both could be simply local manifestations of a larger and more general foraging strategy (or strategies) which humans possess, which could be heritable and an adaptation. A behavioral strategy is, after all, simply a complex behavioral disposition, which involves responding in a variety of specific ways to a set of environmental cues, most of which would be achieved by having an appropriate psychological mechanism or mechanisms underlying the set of dispositions. In which case, heritability of a behavioral strategy only depends on there being a psychological mechanism or mechanisms that produces that strategy reliably, and that mechanism’s itself being heritable. Of course, whether there are such heritable mechanisms for the behavioral strategies in which the HBEs are interested is likely to be a matter of some controversy.
