Evolving Brains, Emerging Gods by E. Fuller Torrey

How the New Science of Brain Evolution Explains Our Existence

This book argues that religious beliefs and gods are by-products of the human brain’s evolutionary development: as hominid brains grew more complex, neural systems that generate agency detection, social cognition, and altered states produced experiences later interpreted as divine. Drawing on neuroscience, anthropology, and clinical psychiatry, it links phenomena such as shamanic trance, hallucinations, and psychosis to the same brain mechanisms that underlie religious experience, and explores how cultural and neurological factors interacted to create gods, rituals, and institutionalized religions.
