attempts to link human behavioral systems to simple geographic or genetic factors

             have always failed. This is because man's major behavioral adaptation is culture.
             Culture is learned and shared. It is rooted in biology. But although this is true (the
             capacity for culture is part of a normal human‛s brain structure), culture frees man
             to an unprecedented degree from strictly biological controls over the development
             and maintenance of behavioral systems. Culture is biologically adaptive. That is,
             human populations imbedded, like all animal populations, in specific environments
             adjust to these environments largely through culture.


             Man is born with a capacity to learn culture, not with culture.
             This does not mean that all human behavior is freed of

             biological programming. Individuals are born different. The
             outcome of heredity and experience will lead to differences in
             temperament and ability which make it possible for the ·
             human group to function as a social entity.


             The human being has been shaped by evolution. His size, the fact that he walks on
             two feet, his relative lack of body hair, and the fact that he can and does talk are all
             products of the evolutionary process. What man does and also what he believes are
                                      also products of evolution. But those elements which depend
                                      upon culture are not inherited biologically. In part, man adapts
                                      biologically to his environment in a non-biological way -
                                      through culture.



                                      Since man is one of the most widely distributed of species
                                      occupying a vast array of environments ranging from deserts
                                      to swampland, from plains to mountains, from inland to the
             sea, and because his social and technological environment varies as widely, we should
             not be surprised to find a range of behavioral variation adjusted to specific
             environments…


              …Humans, as members of social groups, may exhibit behaviors which parallel
             instinctual behaviors in lower animals but which have their origin in culture.

             Variations, cultural or biological, are all subject to selection through the action of
             the environment. If a variation (physical or behavioral, genetic or learned) has an
             advantage over other existing forms in a specific environment, it can be selected for
             in that environment…


             …culture, which is a product of man's biological past, and which
             is man's major way of adapting, is not dependent upon genetic
             variation for change. Aggressive or passive behavior (and
             combinations of these) are both possibilities within the
             behavioral capacities of man. What kind of behavioral system
             emerges must conform to man's biological capacities, but since
             these are wide, the capacities alone tell us little about real systems undergoing the

             selective process.
