Obstetrical dilemma
Evolution of human birth
Humans are born with a very malleable fetal head which is not fully developed when the infant exits the womb. This soft spot on the crown of the infant allows for the head to be compressed in order to better fit through the birth canal without obstructing it. This allows for the head to develop more after birth and for the cranium to continue growing without affecting the birthing process.
