Hypothesis
Contrary to the 'obstetrical dilemma,' there will be geographical variation in the shape of the female birth canal.
Note
Females in sub-Saharan African populations typically have deeper birth canals whereas the birth canals of Native Americans are wider. Asians, Europeans, and North African females typically have an intermediate birth canal morphology.
