Document Summary
Darwin = indiv"s with particular heritable characteristics are more likely to produce offspring that survive (adaptation) adaptations that promote organism"s survival are adapted. Sexual selection = adaptations that increase access to mates selected intrasexual (adapt. for competition within sex for mates) and intersexual (adapt. for selection by other sex) Inclusive fitness theory key to selection is survival of genetic material, not necessarily survival of offspring. Indiv humans are vulnerable groups allow for sharing food collection and distribution, access to mates, shared defense against predators and out groups, shared raising of offspring. Those motivated to belong should be more likely to survive. Need to belong need frequent interaction with others in stable bond marked by affective concern (form small groups); this need is universal, as well as distress for ending relationships. Motivation for physical closeness seen in earliest placental mammals (ex. Social connections promote offspring survival for baboons); humans share motivational systems w/ other animals.
