Rather ironically backtracking to page one to get back on track, it may well be true that dumber is better in a species. Ernst Mayer speculated that it was better to be dumb than smart, in evolutionary terms at least - the most successful species ever include such academic luminaries as bacteria and beetles. Even felinidae's long run looks poor compared to their's.
The upshot of this is that relatively stupid, unified people, fearing things and avoiding what they do not understand as opposed to taming them (in both physical and philosophical terms)may well be better equipped for the stoicism required for survival. This thusly gives religion an evolutionary basis, albeit a roughly composed one.
