Douglas A. Marshall is Professor of Sociology and Director of Honors Education at the University of South Alabama. His research interests orbit the intersections of Sociological Theory, Social Psychology, and Evolutionary/Biological Sociology, especially as they apply to Religion, Rationality, and Epistemology. His probably overambitious attempt to capture and synthesize the depth and breadth of evolutionary/biological sociology into one overstuffed review chapter has just been published in The Cambridge Handbook of Social Theory (Peter Kivisto, ed.)
