While everyone alive today is guaranteed to have ancestors, no one is born with a similar guarantee to have descendants. In a parallel truism, everyone alive in the year 2200 AD will be able to trace his or her lineal ancestry to a parental stock in the year 200 AD. This book addresses two questions 1) "Which facets of current cultures are aligned with enhanced fertility of their members and which facets of current cultures are aligned with reduced fertility of their members?" and (2) "What evolutionary pressures sculpted the reproductive psychology of current women and the behavioral consequences of that psychology?" The argument is presented that women's mating strategies are much more complex than their primate sisters'. Our female ancestors had to evaluate and select as mates those men who were dominant within the male hierarchy plus were nurturing to their children. No other female primate has just a complicated mating calculus to perform. Here we are different. Within the context of the female mating tactics, each intact or coherent (sub) group, community is faced with a conundrum. To wit" if a (sub) group allows each member to maximize his or her own independence and freedom, then this maximization threatens, over generations, the sheer existence of that (sub) group. If cultural continuity is to occur, over generations, then individual freedom and independence are mandated to be restricted. Furthermore, it appears that the social dynamics of cultural evolution have a winnowing effect. Those cultures which restrict selected freedoms of their citizens have a more positive evolutionary trajectory than those cultures without such restrictions. Social and political leaders are encouraged to find the elusive balance between individual autonomy and community stability across generations.
