Types of skull

These bones form a structure with a rounded shape, which could be reminiscent of a kind of vault both in the front and back of the head. The parts that make up the skull are numerous, however, the main bones that form it with the frontal, the parietal, the temporal and the occipital bone.

Types of skull

The types of skull can be categorized in different ways depending on whether the process of evolution is attended to, according to the geographical location of the person or according to the genetic formation of the same. Although animals also have cranial structures, this article focuses on the human race. According to evolution, the types of skull that have emerged over time are:

The one belonging to the first bipedal hominid. It is a smaller skull than the human being currently has. However compared to the size of its body, the bones of the head are relatively large. Its frontal bones are projected forward and it has a small sagittal crest that is similar to that of modern male gorillas.

Homo habilis

It has a somewhat larger skull with a more rounded shape. The occipital bone is in a more central position and the face is somewhat less pronounced than that of the australopithecus. The face has a shorter shape and a large jaw.

Homo erectus

A large skull. Almost twice the size of its Australopithecus ancestor. The frotal bones of the face are short and very wide, with the brow bone very high, with a reduced forehead.

Homo sapiens

With a cranial capacity of 1,400, double that of its predecessors. With a small jaw and a more elongated shape, this skull allows to develop the ability to preserve the powers of the brain for a longer time.

Homo sapiens sapiens

It is the skull that the current human being possesses. With a high forehead and the bones that form the vault species are in a higher position. The bones of the nose, eye sockets and chin are well marked. His brain capacity is similar to that of sapiens.

On the other hand, according to the genetic formation that has been studied by medicine, according to the diameter of the skull, the following can be differentiated:

Dolichocephalic skull

It is a skull that has parietal bones that have joined prematurely, resulting in an elongated and narrow shape that does not allow adequate lateral growth of the skull.

Gill skull

A premature fusion occurs as in the previous modality, but in the area of ​​the coronal suture. This causes the longitudinal growth of the skull to not occur properly, or the back and top to flatten, resulting in a short and wide head shape.

Mesocephalic skull

A cranial shape that sits midway between the dolichocephaly and the gill. A mesocephalic skull is considered to be of normal size, without conspicuous dilation or flattening.

Finally, depending on the place of origin of the people, the skulls present certain differences:

European skull

Also called Caucasian, it has a narrower and elongated shape. With less pronounced cheekbones.

African skull

With a more elongated shape from the part of the jaw to the forehead producing a certain lopsided tendency that causes the jaw to be somewhat more in relief.

Asian skull

Shorter in length, but somewhat wider. With small, round eye sockets and wide cheekbones that reach the lateral part of the skull.
