Human faces are famous for their diversity. People whose ancestors came from China differ in the shape of their eyes from those whose ancestors came from Africa.

Scientists believe that these variations exist because the ancestors of modern people, getting into different climatic conditions, had to better adapt to them in order to survive.

Interesting fact: scientists believe that the diversity in the structure of individuals is due to the adaptation of people to those climatic conditions in which they find themselves by the will of fate.

The difference in the structure of the eyes of different nationalities

The structure and internal content of the eyeball is exactly the same for an African, a European, or an Asian. But many Asians have a crease in the corner of the eye called the epicanthus.

For centuries, Asians have more fat, they are thicker than the eyelids of Europeans or Africans. The larger and thicker the eyelids, the greater part of the eyeball is covered.

Theory of climate dependence of facial structure

Scientists believe that eyeball protection, wide cheekbones and flat noses are parts of a holistic symphony of the structure of the face, thus protected from extremely cold air. If the nose is flatter, then the air passing through the nostrils comes into contact with most of the surface of the nasal mucosa, thereby warming faster and not cooling below the respiratory tract, moreover, with this contact, the air is better cleaned of dust.

Interesting fact: the shape of the eyeball is the same for representatives of all races, the difference lies in the structure of the eyelids.

This theory has confirmation: the inhabitants of Northern China, Mongolia and Siberia have wide-open eyes, and their faces are flatter than those of South Asians. The crease of the upper eyelid and the high cheekbones of the Indians of America, who mostly live in the tropics, also arose in the cold climate in which their distant ancestors lived.

Similarity of the structure of faces in different parts of the Earth

Scientists suggest that tens of thousands of years ago, Asians crossed the Bering Strait (then it froze) and entered Alaska, from where they settled the American continent. Once on the North American continent, people gradually penetrated further and further south, until they mastered the American continent to its southernmost tip. Other groups of Asians colonized Tropical Indonesia, and the coral islands of Polynesia in the South Pacific. That is why today we see traces of the structure of the faces of North Asians among the Eskimos of Alaska, the Indians of Peru and the inhabitants of the islands of Fiji.
