Abstract

Many of the objections to the sociobiological research program arise from putative peculiarities of human beings and human societies when many of them actually arise from the nature of hierarchically organized systems. The levels of selection problem is no easier to handle at the gene-organism interface than at the organism-society interface. The unity of the genotype is just as problematic as the cohesiveness of the gene pool. One distinction which helps to reduce confusion is between replicators and interactors. Implications of various versions of evolutionary theory for human beings are set out.
