C-sections for everyone!

During our evolutionary process, babies' heads were forced to become smaller because the size of the mother's pelvis could not cope with large heads during childbirth. That's easy enough to understand. But it might be that with that restricted size, the size of our frontal lobe and surface area of the cortex got compromised. The frontal lobe (along with other areas in the cortex) is basically what makes us smarter.

So why not put evolution on the fast track? Instead of giving birth naturally and doing nothing for the human race as far as increased intelligence, what if we greatly expand the availability of Cesarean sections? That way, over thousands of generations, our heads will be set free to become as big as they want, and we'll be able to think rationally and not get complacent when there's an important Senate race in Massachusetts.

Of course, all this is an amusing theoretical exercise. There's no strong proof so far that more C-sections help us become more intelligent. But it's still fun to think about.
