Are there only three major races in the world?

The criteria for dividing the world's ethnic groups and the regional distribution of the main ethnic groups;

Most anthropologists in the world agree that human beings originated in Asia and then spread out from Asia and distributed all over the world. In the process of long-term migration, due to the external influence of geographical environment, some changes have taken place in human appearance and physique, forming different races in the world today.

Race is race. It is a huge geographical group formed in history and has the same genetic characteristics as a god in physical form.

What criteria are used to divide races? Nationalities are divided not according to their different languages, customs and nationalities, but according to the different physical characteristics of human beings and their genetic and natural characteristics (belonging to the biological category). As a natural feature, the main indicators are body length, skin color, hair color, hairstyle, eyes, head shape, face shape, nose shape and so on. Accordingly, the world races are mainly divided into white, yellow, black and other races.

Caucasians, also known as Europeans, are the most populous race in the world, accounting for about 54% of the global population. Most white people live in colder areas. The sunlight in this area is oblique, and the light and ultraviolet rays are weak, so the melanin content in white skin is low, from white red to dark brown; Hair is many and soft, wavy blonde or brown hair; Thick body hair can prevent colds; Blue eyes, a tall and narrow nose and a long nostril passage can let cold air slowly enter the lungs.

The distribution of whites is centered in Europe, including America, Australia, India in the East and many countries in West Asia. White people are divided into three parts: Aryans (Germans, Latins, Slavs and Eastern Indians), Han people (distributed in North Africa and Northeast Africa) and Semites (distributed in West Asia, Arabia and Northeast Africa).

The yellow race, also known as Mongols, is the second largest race in the world, accounting for about 37% of the global population, and half of them are from China. Yellow to brown skin; Less body hair, straight and black hair; Brown eyes, flat face, broad forehead; The nose is of medium height.

The distribution of the yellow race is centered in Asia, spreading to the surrounding islands and as far away as the North American Indians. The yellow race can be divided into Mongolian race (the northern Mongolian race is represented by Mongols, the middle Mongolian race is represented by China and North Korea, and the southern Mongolian race is represented by Burmese and Thai), Indonesian race, Indian race and so on. Magyars and Finland in Europe are also yellow people.

Black people, also known as Negroes, are the third largest race in the world, accounting for about 8.5% of the world's total population. Most blacks live in tropical equatorial regions. In this area, the direct sunlight lasts for a long time, the temperature is high, and the ultraviolet rays are strong, so the melanin content in black skin is high, and the skin is protected by absorbing ultraviolet rays from the sun, which is black to dark brown; Hair is thin and short, curly or wavy, and air is filled in the gaps of hair to form a heat insulation layer, which plays a role in protecting the head; Very little body hair; The eyes are brown, the nose is low and wide, and the nostril passage is short, which is convenient for heat dissipation; Long head type; Lip thickness.

The distribution of blacks is centered on sub-Saharan Africa, and also distributed in the New World, India and Sri Lanka. Blacks can be divided into African blacks, Indian blacks and American blacks.

In addition to the above three races, there are some other races. There are mainly Malays with no physical characteristics, and the distribution area is mainly Southeast Asian islands and Oceania. Among them, there are the following departments:

Beddaren, a native of Ceylon, is short and has black or brown skin.

Polynesians, New Zealanders, Maori and Polynesian Islanders.

Australian, brown skin (chocolate color), well-developed body hair and curly hair.

In a word, race belongs to the natural category. Ethnic differences are mainly manifested in natural constitution, and there is no distinction between good and bad. All racist theories of racial superiority are untenable. In today's world, there are still many racists who pursue reactionary racist policies. For example, black Americans suffer from racial discrimination and oppression. This wrong behavior is bound to be resolutely opposed by people who uphold justice in the world.
