Some people think that religion is an adaptation evolved both by cultural and biological evolution to make groups to cohere, in part for the purpose of trusting each other, and then being more effective at competing with other groups.
Neki ljudi misle da je religija adaptacija razvijena kroz kulturnu i biološku evoluciju kako bi bolje vezali grupe radi pojačanja međusobnog povjerenja i stoga u prednosti pred drugim grupama.
