Apparently we are still born with fundamentally the same physical and personal characteristics as our ancestors thousands of generations ago, when the first primordial hordes organized themselves. They developed biologically necessary patterns of communal existence to satisfy instinctive feelings, attitudes, and driving forces which are still present in us. As a basis for comparative purposes we presuppose a hypothetical primitive community whose life centres around a semipermanent homestead with some agriculture and hunting.
