Returning the "Social" to Evolutionary Sociology: Reconsidering Spencer, Durkheim, and Marx's Models of "Natural" Selection

Sociology can no longer avoid engagement with biological ideas, but it can incorporate them where they are useful. Most biologically inspired explanations of sociological processes from outside the discipline are simple and, moreover, too reliant on biological rather than sociological models of social processes. Yet, it is possible to engage these efforts by developing sociological concepts and theories that meet those using evolutionary theory from biology. This paper argues that the heavy reliance on Darwinian natural selection limits sociological explanations, although this approach can help sociologists understand the evolved behavioral propensities of humans as evolved apes. These behavioral propensities cannot, however, explain the evolution and dynamics of the layers of sociocultural phenomena studied by sociologists, and efforts to do so with Darwinian notions of natural selection on individual organisms will always be inadequate. As an alternative, we propose that there are other types of natural selection inherent in the organization of what Herbert Spencer termed superorganisms. We label these Durkheimian, Spencerian, and Marxian selection, and they explain what Darwinian selection cannot: the dynamics and evolution of sociocultural phenomena.
