It's tempting to think that since a group is bigger than an individual, they should have some sort of power to select beyond the individual's procreation - but while groups are more powerful than individuals, groups are not more powerful than procreation.

It's easy to expect, and believe, and accept group selection, because the method of transmission is so obvious, that behaviours are taught to the next generation! This obscure 'years later, gene expression' stuff just seems so unlikely - humans aren't wired to expect causality over years or decades.
