Where are the three major human races in the world located?

The so-called human race refers to the group of people who are divided according to certain traits that can be inherited in their constitution. Its characteristics include the color of **, the shape and color of the hair, the shape of the eyes, nose, lips, etc.

The formation of the human race is mainly the result of the influence of the natural conditions of the region. At the same time, incidental variability and isolation also play a role.

Homogeneity was formed at the time of the emergence of late Homo sapiens.

Ethnicity is generally divided into three or four major categories. The three major categories refer to the race (yellow or Asian-American) and the Euro-Roman race (Caucasian or Caucasian).

and the Negro race.

Black or equatorial race.

The division of the four categories separates the Australian race (brown) from the black race as a separate race.

Four major races. The characteristics and distribution are as follows:

Yellow species - yellowish complexion, thick and straight hair, black color, dark or dark brown eyes, broad face, flat and prominent cheekbones, low nose bridge, canthal folds in the eyes, and slightly upward slope of the outer corners, becoming the so-called "red phoenix eyes, beard and body hair are the most scarce." It is mainly found in most of Asia and the Americas.

Caucasian - white complexion, light hair and eye color, often wavy hair, high and narrow nose bridge, well-developed beard and body hair. It is mainly distributed in Europe, West Asia, South Asia, North Africa and other places.

Black - dark complexion, dark and curly hair, dark eyes, a broad, flat nose, thick and turned lips, and little beard and body hair. It is mainly found in Africa and Australia.

Brown species - mainly found in Australia and New Zealand.

and South Pacific islands.

The people of the world are mainly divided into white, black and yellow races.

Caucasians are mainly found in western Asia, most of Europe, northern Africa, and the east coast of North and South America.

Yellow people are mainly found in eastern Asia, northern North America, and northwestern South America.

Black people are mainly found in most of Africa, northwestern Oceania and other regions.

This is an original answer, please forgive me if there is any deficiency. Thank you.

1.The main characteristics of yellow people are flat faces, single eyelids, low and small nose bridge, and underdeveloped body hair. It is mainly distributed throughout East Asia.

2.Caucasians are characterized by a light complexion; Soft, wavy hair. deep eye sockets; The hair is more developed; low cheekbones; flatter jaws; The bridge of the nose is high; Lips are thin or moderate.

3.Black people are generally characterized by a dark complexion, black wavy or curly hair, dark eyes, a broad, flattened nose, a low or medium nasal base, small nasal protrusion, large transverse nostrils, convex lips, wide mouth, thick lips, and less beard and body hair.

1. The Europa race (Caucasian) is the most populous race in the world, accounting for about 54% of the total population. 2. The Mongolian race (yellow race) is the second largest race, accounting for about 37%. 3. Negro people (black race) account for 8.5%.Other races accounted for 0.5% satisfaction.

The three major races in the world are: yellow, black, and white. They are distributed separately:

Yellow people are mainly found in eastern and Southeast Asia; Black people are mainly found in the tropical equatorial regions of non-starvation continents and the African continent south of the Sahara Desert; Caucasians are mainly found in central and northern Europe. The characteristics of the three major races are: yellow people** are brownish-yellow, have less physical appearance, have straight and black hair, and brown eyes.

Black people have a black or dark brown complexion, and their hair is black, short and curly. Caucasians have a pale and pale complexion, soft golden yellow or brown hair, wavy hair shape, and turquoise or grayish-brown eyes.

Ethnicity is a group of human beings with common genetic and physical characteristics. Race, also known as race, is biologically a species of all human races, Homo sapiens. Different races are equivalent to several varieties of a species, all of which originate from a common ancestor.

Although different races have differences in skin color, eye color, hair color, hairstyle, head shape, height and other characteristics, these differences in characteristics are due to the long-term adaptation of human beings to the local natural environment in a certain area, and the formation of rotten things after long-term isolation.

Ethnographic classification, especially ethnographic classification based on a single trait, has been abandoned by the vast majority of scientists because of its irrationality and scientific ineffectiveness. American scientists have found that human differential genes have risen from 10%.

The yellow race is mainly distributed in the eastern part of Asia and Southeast Asia, the white race is mainly distributed in central and northern Europe, and the black race is mainly distributed in the tropical equatorial region of the African continent, and is also distributed in the New World, India and Sri Lanka, among which the white race is the most populous race in the world.

The world's most populous Caucasian, Caucasian accounts for about 43% of the world's population, yellow people account for about 41%, black people account for about about it, and others account for about it.

The white race, also known as the "Europa race" and "the Golama race", is native to Europe, North Africa and other places, and is mainly distributed in Europe, North Africa, West Asia and Oceania.

According to the differences in physical characteristics, the human race in the world is roughly divided into three major races, namely the yellow race, the white race, and the black race, and some people advocate the separation of the brown race.

The world's three major hail blind races are mainly distributed in the continents of the source tribe. （）a.Europe. b.Miho Xuzhou.
