Leaving aside the intelligent design and interpretation of Genesis questions, which I could write articles about if I had time, there are a number of issues with having zippers in our bellies. Once I became pregnant, I became aware of the intense work done by the abdominal muscles -- they are, for example, critically important to such basic things as walking, getting out of bed, etc. Simply being pregnant is already pretty hard on them; I can't imagine what would happen if we then tried to decrease their structural integrity by adding a zipper (or other mode of opening).
BTW, this realization also increases my determination to avoid c-section births whenever possible; that recovery time is awful!
But yes, the giant brain issue is very real. I have heard a few people voice a theory that makes some sense to me -- that like marsupials, we humans give birth to essentially premature infants, because for us it's the only way to get the baby out while the head is still small enough to fit. Unlike marsupials, we are not equipped with built-in pockets to carry our premature infants in, so we have to use our arms or invent some other device to help hold them. Thankfully, we have big brains to enable us to overcome the problems caused by having big brains. :)
