Although the world's human races are generally divided into yellow, white, black and brown in the north, due to historical population migration and ethnic integration, a number of transitional human races between the four major human races have emerged. For example, the Indian race in the Americas is usually listed as the same as the East Asian race, but the skin color of the Indians is more intense and has a reddish hue than the East Asian race, and its blood type characteristics are also different from the East Asian race, so the Indians who are also yellow people still have obviously different physical characteristics from people in East Asia, Japan, South Korea and other countries.
East African blacks and West African blacks also look different: West African blacks are tall and burly, have high muscle density, extremely slender limbs, good explosiveness, excellent bouncing power, and are very advantageous in the fields of sprinting, basketball, and football; in contrast, East African blacks are thinner, but East African blacks have better endurance, and have an advantage in marathon and long-distance running. In fact, Ethiopians in East Africa are not as dark-skinned as West Africans and are more like transitional races between blacks and whites.
The white races in southern Europe, the Middle East and other places are relatively darker than the Nordics in terms of skin color and eye color, and the hair is mostly black, which is obviously different from the blonde Nordic Germanic race. In fact, human racial differences are themselves the product of adaptation to the living environment: the main ethnic group in India, the Hindustani, belongs to the Indo-European race (white race), but many Indians who have lived in the tropical environment for a long time are not white. It is easier to distinguish between Indians and Europeans and Americans of the same white race.
People in China, Japan, and South Korea in East Asian countries seem to be difficult to distinguish between Europeans and Americans in appearance, so there will be Chinese who are treated as Japanese and Koreans overseas, and in fact, it is also difficult for us to distinguish between British, French, and Germans directly from their appearance. So are there differences in appearance between Japanese, Korean, and Chinese? In fact, there are still some objective differences, but these subtle differences are difficult to identify at a glance. Just like the players on both sides of the football field know the concept of offside, but it is sometimes difficult to distinguish after actually running.
First of all, we need to correct the established concept that China, Japan, South Korea and other countries are the same race. China has been a multi-ethnic country since ancient times, and the vast majority of the 56 ethnic groups in china belong to the Mongolian race, which is what we usually call the yellow race. However, it is inappropriate to define the entire Chinese as yellow people: the Tajik, Uyghur, Kazakh and other ethnic groups living in Xinjiang, China, have obviously different physical characteristics from the Han chinese and other ethnic minorities living in the interior, so not all Chinese are yellow people.
Even the Han nationality, as the main ethnic group in China, is not a single source: when Qin Shi Huang marched south to Baiyue, the Jiangnan and Lingnan regions were still barbaric places where the Baiyue people were infested, but now these areas all use the same square characters. So where did the Ancient Yue people, who were the indigenous inhabitants of these areas, go? Obviously, some of the Southern Han people today have ancient Yue ancestry. In fact, the history of China and even the history of all mankind is the history of continuous national integration and evolution, and to this day no one can guarantee that their ancestors must have no other races.
This phenomenon of racial integration is not unique to China. Japan, as a relatively closed island nation, is relatively homogeneous in terms of ethnic composition, but it cannot simply be called a "mono-nation state". In addition to the Hokkaido region, the main ethnic group in Japan is the Wa ethnic group, which makes up more than 98% of its total population, and there are about 20,000 Ainu people living in the Hokkaido region – their appearance is very different from that of the Wazu people: their eyebrows are prominent, their hairs are dense, their eyes are round and deep, their eyelashes are long and divergent, their noses are vertical, and their faces and whole body are hairy, with distinctLy Europa ethnic characteristics.
The Japanese nation is actually a mixed ethnic group: the He ethnic group, as the main ethnic group in Japan, was formed by the fusion of Han immigrants from the lower reaches of the Huai River and the lower Yangtze River in China with the Tunguska people from Siberia and northeast China, the Malays of the Nanyang Islands, the Indochins of the Indochina Peninsula, and the ancient Koreans. Before the ancestors of the Wazu landed on the Japanese archipelago, the Ainu lived extensively throughout the Japanese archipelago, Sakhalin Island and the Russian Far East, while the living space of the early indigenous Ainu people in the process of the Unification of the Japanese Archipelago was constantly squeezed.
Of course, in this process, a considerable part of the early indigenous peoples were also integrated into the He clan. Japanese actor Hiroshi Abe and singer Ken Hirai have more typical early Aboriginal physical features: their deep facial features look closer to those of Europeans and Americans, which is different from other Japanese physiognomy. It can be seen that Chinese, Japanese, and Koreans have actually experienced a long process of national integration in history, and it is completely normal to have certain differences in physical appearance in this process.
In fact, even within the same race and ethnic group, there will be certain differences in physical appearance due to different living environments: the average height of northern Chinese people is higher than that of southern Chinese, and this difference in height is actually not a physical difference? It's just that it's hard to tell the difference between northerners and southerners at a glance based on this subtle gap. There are indeed certain differences in the appearance of Japanese and Koreans and Chinese, but in reality, it is difficult to distinguish Japanese and Koreans from Chinese in appearance through these subtle differences.
In fact, it is far easier to distinguish Japanese, Koreans, Chinese in terms of language, clothing, makeup, etc. than it is to distinguish between them in appearance, but there are some subtle differences in appearance between them. Previously, a research institute used the computer big data function to produce the average appearance of the world's countries, showing that Korean men have more prominent physical characteristics such as single eyelids and small fine eyes, and this physical characteristic is also more common among the Manchu, Mongolian, Hezhe, Evenk and other ethnic groups in northeast China.
Anthropologists believe that single eyelids and small eyes are a special physical appearance evolved by northeast Asian peoples in the process of adapting to the local environment. The perennial cold climate of Northeast Asia has gradually accumulated more and more fat in the upper part of the eyes due to the human adaptation environment in this region, so that the eyes can be better protected in the case of severe cold and wind. In addition to single eyelids and small eyes, another common feature of Koreans is that the flat facial features lack a three-dimensional sense. In contrast, people with a more three-dimensional face and a high nose and big eyes are relatively common in China.
As the main ethnic group of Japan, the Wa ethnic group has a phenomenon of mixed fusion with the early aborigines of the Japanese archipelago in the process of formation: if there are more early aboriginal genes in modern Japan, they will show the physical characteristics of deep facial features and dense hair, and on the contrary, if they are more close to the population from Chinese mainland and the Korean Peninsula, they do not have such physical characteristics, and even some Japanese people may have dwarf black genes from the Nanyang Islands. Another obvious feature of the Japanese is that there are many people with tooth decay.
Many popular film and television stars in Japan look at the beauty of the face are beautiful and handsome, but a mouth can see the teeth crooked. In fact, the phenomenon of irregular and irregular teeth in the Japanese has a long history, and even during World War II, there were anecdotes that Japanese pilots could not bite the breathing mask due to tooth problems. As an island country, Japan's animal husbandry industry is not developed, the meat eaten by the ancient Japanese is mainly fish, and there are few large pieces of meat with skeletons on the table of the ancient Japanese, so the Japanese do not eat meat with bones for thousands of years.
This made their teeth lack friction with animal bones, so the Japanese gums were not fully squeezed for a long time, resulting in very irregular teeth over time. In contrast, the Chinese from the snack hard food allows the gums to be fully squeezed. Another characteristic of the Japanese is that the legs are not well developed: short legs and short legs have also been a more prominent physical feature of the Japanese. Honda Tadatsukatsu, known as the first fierce general of the Japanese Sengoku, is only about 1 meter 4 tall according to historical sources. Why were the ancient Japanese so short?
Ancient Japan, as an island country with an underdeveloped animal husbandry, ate almost no meat except for fish, coupled with the unique sitting posture of the Japanese people, which caused stunted leg bone development due to long-term compression of the legs. After the Meiji Restoration, Japanese people began to learn to eat steak and drink milk in the West, so that after more than half a century of growth, the average height of Japanese people grew by 12 centimeters, which exceeded the Chinese at that time. In recent years, with the improvement of Chinese living conditions, the difference in average height between Chinese and Japanese people has been basically erased.
