Needs to get out more. Take one trip to some nations in Africa, and you'll quickly discover there are indeed, thousands of peasant cultures undergoing, um, "selection pressures". Usually at the expense of one another. Even happens in places where we think, on the surface, one of the global culture holds sway. There are Indians out there, for instance, who might say, "Sure you may be Muslim, but you'd best be not just Muslim, but Medthavese, for my daughter." There's likely one global culture for the author because they don't observe the others. Like many people they overlook, or don't bother observing at all, critical details. Out in the world, however, it's the details that do you in. That's doubly true on evolution's timescale.
