Nearly everyone would agree that humans and their societies evolved by natural selection, that humans are biologically a single species but societies vary greatly, and neither genetic inheritance nor cultural inheritance alone can fully explain humans and their social systems. While there is a literature that addresses dual inheritance theory or the coevolution of culture and genetics, almost all of it is written from a perspective that accepts the neo-Darwinian evolutionary framework but does not give proper weight to social and cultural theory as it has been developed by cultural anthropologists. At the same time, cultural anthropologists have ignored the question of dual inheritance altogether, leaving the theorizing of how it works almost exclusively in the hands of those with a strong biological viewpoint. In this book anthropologist and psychoanalyst Robert Paul attempts to reconcile evolutionary and cultural approaches in anthropology through a comparative ethnographic exploration of how humans receive behavioral instructions from two separate channelsthe genetic code carried in the DNA and the symbolic systems that constitute culture. He develops a dual inheritance model that aims to do justice to both the genetic and cultural channels of inheritance. Paul elaborates his model of the relationship between genes and cultural symbols and then shows how it can make sense of both the similarities and variations found in human social life as captured in the now very extensive ethnographic record. He argues that cultural systems evolve to manage intra-group competition that would ensue from the genetic program pursuing its interests. The book uses thick descriptions and heavy interpretations from the ethnographic record to demonstrate how different societies tackle this challenge. The book fills a niche, connecting the dual-inheritance literature and symbolic cultural anthropology, using insights from the former to detect patterns in the latter. This is a rare and well-researched project, and should receive a broad readership among biological and cultural anthropologists, and students of human nature more broadly."
