The evolved function of brain, cognitive, affective, conscious-psychological, and behavioral systems is to enable animals to attempt to gain control of the social (e.g., mates), biological (e.g., prey), and physical (e.g., nesting spots) resources that have tended to covary with survival and reproductive outcomes during the species' evolutionary history. These resources generate information patterns that range from invariant to variant. Invariant information is consistent across generations and within lifetimes (e.g., the prototypical shape of a human face) and is associated with modular brain and cognitive systems that coalesce around the domains of folk psychology, folk biology, and folk physics. The processing of information in these domains is implicit and results in automatic bottom-up behavioral responses. Variant information varies across generations and within lifetimes (e.g., as in social dynamics) and is associated with plastic brain and cognitive systems and explicit, consciously driven top-down behavioral responses. The processes that compose natural selection are harsh and unforgiving and were thus described in by Darwin and Wallace (1858, p. 54) as a "struggle for existence." Life and reproduction are indeed a struggle for most individuals of most species, and there is little doubt that human evolution was filled with many such struggles, and that people continue this struggle in many parts of the world today. Still, humans do not have to struggle quite as hard as most other species simply to exist, that is, to stay alive. As proposed by Alexander (1989), our extraordinary ability to modify (e.g., build damns) and extract resources (e.g., using other species as food) from the ecology, and then use these resources for survival and reproductive ends makes us different from other species. This difference is best captured by Alexander's proposal that at some point during human evolutionary history our ancestors achieved ecological dominance. Once an ability to dominate the ecology was achieved, there was an important shift such that the competing interests of other people and coalitions of other people became, and remains, the central pressure that influenced human evolution. From this perspective, natural selection remains a "struggle for existence," but becomes primarily a struggle with other human beings for control of the resources that support life and allow one to reproduce (Geary, 1998(Geary, , 2005.Whether or not the struggle is primarily social, human behavior and that of other species can be conceptualized in terms of an evolved motivation to control. I am not arguing individuals of all species have a conscious, explicit motive to control other members of their species (e.g., mates) or other species (e.g., prey species). Rather, the result of natural and sexual selection (e.g., competition for mates) will be the evolution of brain, cognitive, affective, and conscious-psychological systems that will be sensitive to and process the types of information that have covaried with survival and repro...
