How can something as cultural as religion be studied from an evolutionary perspective?
It is typical to portray terms such as “culture” and “learning” as alternatives to terms such as “evolution” and “biology.” According to this formulation, evolutionary theory can explain other species and certain aspects of humans, such as our desire to eat and mate, but not other aspects, such as our rich cultural diversity. This formulation makes little sense from a modern evolutionary perspective. Culture and learning are manifestly important in our species, but they need to be understood from an evolutionary perspective rather than being regarded as an alternative. The capacities for learning and culture require an elaborate architecture that evolved by genetic evolution. Moreover, learning and cultural change can be regarded as fast-paced evolutionary processes in their own right. The bottom line is that evolutionary theory provides a framework for understanding cultural diversity in addition to biological diversity.
