In God Delusion RD said, “Darwinian selection habitually targets and eliminates waste. Nature is a miserly accountant, grudging the pennies, watching the clock, punishing the SMALLEST extravagance."

RD also said regarding religion, "[The child brain] is susceptible to and carries the down side of bad ideas, useless ideas, waste of time ideas like rain dances and other religious customs." And that human brain modules are “vulnerable to misfiring in the same kind of way as I suggest for childhood gullibility.”

Given that evolution eliminates waste and punishes the smallest extravagances, wouldn't have evolution selected against ubiquitous religion over tens of thousands of years if it was a useless, wasteful misfiring error of the brain rather than increasing fitness and being adaptive?
