The obstetrical dilemma has been studied widely because it has increased the difficulty of childbirth for modern day women. Because of this, complications in birth are more frequent as well as the need of assistance in childbirth. This change seems to have evolved over time because this dilemma does not seem to pose a problem for our most recent relatives, non-human primates, who still manage to give birth with little difficulty."@en }
