I agree with that, but that's not what I meant. The mother's pelvis only
determines the brain size at birth, but you still have quite a ways to go
between the size of your head at birth and the adult size. What I find
surprising is that bone growth (the calvarium) should be _regulated_ in any
way by the growth of a soft tissue like the brain.
