Human behavior evolved during a 5 million year period as hunter-gatherers to confer genetic fitness: increased personal survival, increased personal reproduction, and the enhanced survival and reproduction of close relatives who share the same genes by common descent. Chimpanzees are our little-brother species and similar in many respects, but no human could successfully emulate the life and behavior of a chimpanzee. Human nature is one idiosyncratic hodgepodge of traits out of many conceivable. The 67 common human characteristics listed by Murdock include courtship, faith healing, penal sanctions, etc. Human behavior has a large genetic component.
"Which of the censors and motivators should be obeyed and which ones might better be curtailed or sublimated?" GENETICSĮach species is an evolutionary experiment.
Will the transcendental goals of societies dissolve, and will our post-ideological societies regress steadily toward self-indulgence? (1) We lack any goal external to our biological nature (for even religions evolve to enhance the persistence and influence of their practitioners). "If humankind evolved by Darwinian natural selection, genetic chance and environmental necessity, not God, made the species." "The brain exists because it promotes the survival and multiplication of the genes that direct its assembly." The two apparent dilemmas we face therefore are: 16 and 222 ) as the scientific or systematic study of the biological basis of all forms of social behavior, in all kinds or organisms including man, and incorporating knowledge from ethology, ecology, and genetics, in order to derive general principles concerning the biological properties of entire societies.
