Written by leading theorists and empirical researchers, this book presents new ways of addressing the old question: Why did religion first emerge and then continue to evolve in all human societies? The authors of the book—each with a different background across the social sciences and humanities—assimilate conceptual leads and empirical findings from anthropology, evolutionary biology, evolutionary sociology, neurology, primate behavioral studies, explanations of human interaction and group dynamics, and a wide range of religious scholarship to construct a deeper and more powerful explanation of the origins and subsequent evolutionary development of religions than can currently be found in what is now vast literature. While explaining religion has been a central question in many disciplines for a long time, this book draws upon a much wider array of literature to develop a robust and cross-disciplinary analysis of religion. The book remains true to its subtitle by emphasizing an array of both biological and sociocultural forms of selection dynamics that are fundamental to explaining religion as a universal institution in human societies. In addition to Darwinian selection, which can explain the biology and neurology of religion, the book outlines a set of four additional types of sociocultural natural selection that can fill out the explanation of why religion first emerged as an institutional system in human societies, and why it has continued to evolve over the last 300,000 years of societal evolution. These sociocultural forms of natural selection are labeled by the names of the early sociologists who first emphasized them, and they can be seen as a necessary supplement to the type of natural selection theorized by Charles Darwin. Explanations of religion that remain in the shadow cast by Darwin’s great insights will, it is argued, remain narrow and incomplete when explaining a robust sociocultural phenomenon like religion.


For decades, evolutionary analysis was overlooked or altogether ignored by sociologists. Fears and biases persisted nearly a century after Auguste Comte gave the discipline its name, as did concerns that its effect would only reduce sociology to another discipline – whether biology, psychology, or economics. Worse, apprehension that the application of evolutionary theory would encourage heightened perceptions of racism, sexism, ethnocentrism and reductionism pervaded.

Turner and Machalek argue instead for a new embrace of biology and evolutionary analysis. Sociology, from its very beginnings in the early 19th century, has always been concerned with the study of evolution, particularly the transformation of societies from simple to ever-more complex forms. By comprehensively reviewing the original ways that sociologists applied evolutionary theory and examining the recent renewal and expansion of these early approaches, the authors confront the challenges posed by biology, neuroscience, and psychology to distinct evolutionary approaches within sociology. They emerge with key theoretical and methodological discoveries that demonstrate the critical – and compelling – case for a dramatically enriched sociology that incorporates all forms of comparative evolutionary analysis to its canon and study of sociocultural phenomena.


On Human Nature

by Jonathan H. Turner

Published 24 November 2020

In this book, Jonathan H. Turner combines sociology, evolutionary biology, cladistic analysis from biology, and comparative neuroanatomy to examine human nature as inherited from common ancestors shared by humans and present-day great apes. Selection pressures altered this inherited legacy for the ancestors of humans—termed hominins for being bipedal—and forced greater organization than extant great apes when the hominins moved into open-country terrestrial habitats. The effects of these selection pressures increased hominin ancestors’ emotional capacities through greater social and group orientation. This shift, in turn, enabled further selection for a larger brain, articulated speech, and culture along the human line. Turner elaborates human nature as a series of overlapping complexes that are the outcome of the inherited legacy of great apes being fed through the transforming effects of a larger brain, speech, and culture. These complexes, he shows, can be understood as the cognitive complex, the psychological complex, the emotions complex, the interaction complex, and the community complex.


Few concepts are as central to sociology as institutions. Yet, like so many sociological concepts, institutions remain vaguely defined. This book expands a foundational definition of the institution, one which locates them as the basic building blocks of human societies—as structural and cultural machines for survival that make it possible to pass precious knowledge from one generation to the next, ensuring the survival of our species. The book extends this classic tradition by, first, applying advances in biological evolution, neuroscience, and primatology to explain the origins of human societies and, in particular, the first institutional sphere: kinship. The authors incorporate insights from natural sciences often marginalized in sociology, while highlighting the limitations of purely biogenetic, Darwinian explanations. Secondly, they build a vivid conceptual model of institutions and their central dynamics as the book charts the chronological evolution of kinship, polity, religion, law, and economy, discussing the biological evidence for the ubiquity of these institutions as evolutionary adaptations themselves.
