Second, this collection of cognitive programs evolved in the Pleistocene to solve the adaptive problems regularly faced by our hunter-gatherer ancestors-...

Darwin, Sex and Statusargues that a human sociobiology that mistakes evolutionary theory for theories of psychology and culture is wrong, as are psychologies that could never have evolved or social sciences that posit impossible psychologies. Status develops theories of human self-awareness, cognition, and cultural capacity that are compatible with evolutionary theory. Recurring themes include: the importance of sexual selection in human evolution; our species' preoccupation with self-esteem and relative standing; the individual as an active strategist, regularly revising culturally provided information; (...) and awareness as an impressionmanagement device. Culture is a somewhat structured information pool that itself evolves, often in ways that reduce the genetic fitness of its participants. (shrink)

Problems of sustainability and survivability are best met not with moralizing but with policies that take advantage of our increasingly understood evolved human psychology. This knowledge helps us understand why our problems recur, and why we need not expect them to have permanent solutions. What is needed is an evolutionary praxis. It is possible, for example, to create policies that work around our tendencies to hierarchize and to form into ethnocentric and mutually hostile groups. Although in many ways there may (...) be a mismatch between our evolved human nature and contemporary society, the fact that it is we who construct our environments must reduce the extent of mismatch.

Human hyperculture appears to have been produced by the amplification of the kind of normal culture shared by cetaceans and other animals and presumably by our ancestors. Is there any possibility that cetaceans could be subject to these amplifying processes, which may include: sexual selection; within-group moral behavior; culling of low- cultural-capacity individuals through predation or self-predation; and reciprocal positive feedback between culture and the capacity for culture.

Because human cultures are far more similar than they are different, culturally constituted niches may work to limit or prevent the development of genetically based psychological differences across populations. The niche approach further implies that we may remain relatively well-adapted to contemporary environments because of the latter's cultural niche continuity with ancient environments.
