Religion co-evolves with the people, places, and times in which it exists. Much like human genes, it works at the level of the individual, the local group, the larger groups and communities (of both the religion itself as well as the polities around it), and when applicable at the scale of all people on the planet.

The Selfish Religion: How far might we take this religion/gene analogy with respect to Richard Dawkins' thesis (1976). Does religion act more like a gene that is part of the particular person or is it more like a virus which inserts itself? The latter may be closer as one can pick and choose a religion rather than it being a core part of their genetic identity.
