The Skull Theory

The Skull Theory originated from the Anthropological approach to the study of humans. Male skulls are more blockier and large compared to the female skull which are more round and delicate. The differences between the male and female skull develop during the maturity of the human, therefore not medically proven to be used on a developing baby. The ‘Skull theory’ seems to have originated online from many expectant parenting sites and discussions regarding baby gender and the skull differences between their boy and girl scan pictures. From this the trend has continued and many claim it has a high accuracy of 92%.

The Skull Theory differences between the male and female skull are described below.

The Skull Theory male and female skull

 

A. The mans cranial mass is more blocky and massive compared to the females which is rounder and tapers at the top.

B. Temporal Ridge – runs along the outer side of the upper skull creating the square shaped of the upper head. More prominent in men than women

C. A woman’s supraorbital margin (the ridge above the eyes) is sharper border, while the males is rather round, dull and blunt.

D. The Zygomatic bone (the cheekbone that lies under the lower eye ridge) is more pronounced on the male skull.

E. The Mandible (lower jaw) bone of a woman is rounded, while the male’s is squared.

F. Frontal bone forehead structure terminates at the brow. The male forehead is lower and more slopping.

G. Male skull have a deeper cranial structure.

H. The superciliary arch is large and pronounced in the man, females often have none at all.

I. A males gonion (most posterior inferior point on angle of mandible) is more flared out and sharply angled.

J. The teeth of men tend to be larger

 

The Skull Theory Origin

The Skull theory although fun, has grey areas. Ethnicity and modern age affects the theory, for example modern Chinese men are much smaller than the average man who is from the Netherlands (home to the tallest men). Since the Anthropological era, world travel increases and people of different racial backgrounds intermix and produce children, therefore becoming harder to differentiate individuals of different races by their skull alone.

We advise this theory to be taken as entertainment only due to there being no medical evidence to support this theory for a baby gender prediction. However the Ramzi theory is available from gestation weeks 6-8, and the Nub theory from weeks 12-16.
