Skull theory

Updated: Jan 25

The theory of skull theory was first introduced following an examination of the distinctions between male and female skulls, which intrigued anthropologists. Expectant mothers were captivated by the theory, hoping to ascertain the gender of their unborn child. Some even asserted an impressive 92% accuracy rate for this method. So, what exactly does it entail?



The differences between male and female skull shapes:



A) The male skull is broader and more "blocky," presenting a larger, more robust shape in contrast to the female skull, which is rounder, narrower, and tapers at the top.


B) The temporal ridge, located on the outer side of the upper skull, is notably more pronounced in males. Furthermore, the male skull's temporal ridge exhibits a more angular, squarer shape.


C) The supraorbital margin (the ridge above the eyes) of a woman's skull is sharper, whereas the male skull's supraorbital margin is rounder and more pronounced.


D) In the male skull, the zygomatic bone (the cheekbone beneath the eyes) is notably more pronounced compared to the female skull.


E) The mandible bone of a woman is rounded, while the male’s jaw is square.


F) The frontal bone on the forehead of a male is sloped compared to the female skull which terminates at the brow.


G) Men have a much larger and longer skull.


H) The superciliary arch is large and pronounced in the male compared to the female.


I) A males gonion (back of the jaw) is sharp and angled.


J) Men have larger teeth in general.


What anthropologists uncovered is undoubtedly a fascinating insight into the distinctions between male and female skulls. However, employing this study to predict the gender of a fetus during ultrasound is nearly impossible. The anthropological studies focused on adult male and female skeletons, not on developing babies in utero. These anthropological variances are rarely discernible during an ultrasound, especially on such small fetuses.


Additionally, there are notable geographical differences between male and female skulls, with significant variations among Asian, African, and European skulls.


Utilising this theory when examining ultrasounds is, in fact, invalid and lacks accuracy. This is due to the ongoing formation of a baby's skull, as well as the fact that each ultrasound image displays varying shapes and sizes of skulls, even within the same baby.


Consequently, this theory should only be used for entertainment purposes.
