Episode 54: The Obstetrical Dilemma

June 04, 2021 18:59 - 34 minutes - 47.9 MB

The widely-held idea known as the “obstetrical dilemma” is a hypothesis that explains why babies are so helpless, and why childbirth is so difficult for humans compared to other animals.  The obstetrical dilemma suggests that babies are born early so their big brains can fit through the mother’s pelvis, which can’t get any wider due to our method of bipedal locomotion. This problem, the idea says, is solved by an evolutionary tradeoff that increases risks to pregnant mothers who must strug...
