Interesting. It is generally accepted that babies are born premature because the size of our brain grew faster than what evolution would permit the width of pelvis. As we became bi pedal, and walking upright, narrow pelvis had an evolutionary advantage. It would be interesting to know the babies died. Is it due to anatomical design or is it evolution? Larger mammals have longer gestational..like elephants and whales.
