      How do you *know* it's proportional ? It may be highly non-linear in nature. Intelligence could be an emergent property, as opposed to intrinsic. There could be a minimum (or maximum) neuron-quantity threshold for intelligence to occur, the decision-surface for relative intelligence could be as complex as a fractal plane. We don't know.

      I think you're overlooking the incredibly difficult process humans go through in childbirth. The non-assisted mortality rate (for both mother and child) is far higher than any other mammalian species on the planet. Primate females almost always give birth without excessive labour. Human females labour can last over several hours, although today the child is more likely to be induced or surgically delivered. Only 200 years ago, death in childbirth was commonplace for those who could not afford assistance.

      In contrast, being hit on the head hard enough to significantly break the skull will pretty much cause damage whatever size brain you have. Since all the higher-order functionality is on the outside of the brain (grey matter), that's the area that would be damaged anyway. If you don't break the skull, you're likely to just get a bruise either way, so long as you don't make a habit of it...

      Don't forget that (unless our ancestors were particularly keen on headbutting cliffs) this would be an effect on 1 person. The do-or-die childbirth thing is an issue for every human born. I suspect nature might come down on the side of the majority...
