ABSTRACT
With the emergence of cultural systems, a radically new mode of adaptation was established and the stage was set for hominid populations to move with amazing speed from their long-time position of relative obscurity to their present position of dominance in the vertebrate world. The emergence of cultural systems did not, however, free human societies from their dependence on genetic and neurological systems of information. On the contrary, these continued to be powerful forces in human life, but now they were supplemented and enhanced by a unique and powerful new information source.
