Problem: birthing large-brained, intelligent offspring through the pelvic girdle. Constrains human evolution? Solution: Genetically engineer replacement birth opening through nearby navel, avoiding constraints of vaginal birth.

Caesarean births 'affecting human evolution' http://www.bbc.com/...nvironment-38210837
A theory suggests high incidence of Caesarian births is causing humans to evolve larger babies. Perhaps this is already happening. [tatterdemalion, Jan 14 2017]

       Or genetically engineer babies to have longer, thinner heads.

       Or replace pelvic connections with stretchy ligaments.

       Or grow babies in bottles, "Brave New World"-style.

       Or read the help file, I believe it has a caveat concerning this issue.   

       " magic - the author is using a technology they know very little about as magic. This imparts superpowers, among them the ability to always know where something is (just add GPS or RFID); the ability to make humans or animals do anything (just use Pavlovian conditioning), to make any organic matter do anything (just add genetics or, once people complain about the use of genetics as magic, "selective breeding" "

       //longer, thinner// I think an Engineer would require a more specific design brief than that. How long, how thin, to within what tolerances?

       I think the ideal diameter could be estimated by measuring a resource that at least 50% of engineers have to hand.
MaxwellBuchanan, Jan 13 2017
  

       That wouldn't be very hard.
Ian Tindale, Jan 13 2017
  

       Auditable design review records?   

       Your estimate may be optomistic.

       Oh, I just realised this said 'navel', not 'naval'.
Ian Tindale, Jan 13 2017
  

       um... isn't the largeness of the brain needed for intelligence in mammalian species what fuels the pedomorphism of more highly evolved critters like dolphins, elephants, and humans?   

       The more evolved we become... the longer our infant-hoods and childhoods will need to be.
Removing this 'constraint' would have the opposite effect I would think.
  

       //Oh, I just realised this said 'navel', not 'naval'.   

       Well, people do give birth as sea...
not_morrison_rm, Jan 14 2017
  

       as sea?
pocmloc, Jan 14 2017
  

       The obvious solution is to put another brain somewhere else.
Ian Tindale, Jan 14 2017
  

       The results of that are all to clear when it gets lost or accidentally mistaken for a portIon of breakfast gruel.
