2. Caucasian: fair skin, light brown, gray and light blue eyes, golden wavy hair, thin nose, thin lips and tall figure, distributed in southern Oceania and Europe.
3. Black race: dark brown skin, black (brown) eyes, short curly hair, low and wide nose (flat), thick lips and long limbs, located on the south bank of the Arctic Ocean.
Of course, the yellow race mainly comes from China and originated from China. There are many specific places, such as Xiangshan Dingren, Beijingers and so on. Primitive people have been found from Yunnan-Guizhou in the south to Beijing in the north. The people of China created a splendid civilization in ancient times. The famous human civilization in ancient times was Dawenkou culture. Later, the Huaxia nationality, which originated in the middle and lower reaches of the Yellow River, unified the middle and lower reaches of the Yellow River and parts of the Yangtze River under the leadership of the Yellow Emperor, established a country and developed into a later Chinese nation. Indigenous people in the south have also established countries in the south and other places, like Vietnam now. At the same time, in South Asia, ancient Indians also established countries. They all belong to the yellow race. Note that the Indians here are not modern Indians, but ancient Indians. So yellow people mainly live in Asia. But more than 10,000 years ago, because the climate became colder and colder (the latest ice age), the sea water in the Bering Strait froze, so some yellow people from northern Asia came to the United States from the ice, and later they were called Indians. These are all yellow people.
White people originated in the Middle East, eastern Europe and the Mediterranean, and later spread to all parts of Europe and North Africa. The main ethnic groups are Assyrians, Jews and Arabs.
Black people originated in Africa. Due to backwardness, few ethnic groups left behind ancient civilizations. In addition, the history of African blacks was interrupted by the looting and slavery of Africans by modern Europeans. So far, the study of black history is mainly about European whites, so there is not much research on them.
