What is racial discrimination?
Recently, this racial discrimination is getting hotter and hotter in China, and from time to time I will hear some remarks or things about racial discrimination. However, I always felt that this matter had nothing to do with China, and I always felt that it was an American matter and a black matter. Even if there is some discrimination, it may be discrimination within the region, such as discrimination between urban people and rural people, or. Discrimination by natives against outsiders, but such inter-ethnic discrimination has hardly been heard of, but it has increased in the past two years. I don't know why,
According to some of the current scientific and anthropological research conclusions, let's roughly sort out the process of human migration, see where the Chinese came from, and how the distribution of people of all ethnic groups in the world was formed.
The consensus now is that 200,000 years ago, we modern Homo sapiens began to be born on the African continent. The earliest were cluster A
Then after tens of thousands of years of evolution and migration, it spread to many parts of Africa. The B population also evolved. There are also CF and DE clusters.
About 70,000 years ago, human beings began to gradually migrate and spread beyond Africa.
First of all, we must first introduce the distribution of ancient humans outside the African continent at this time, there are three large groups, they are Neanderthals distributed in Europe and West Asia, as well as Denisovans distributed in East Asia and North Asia, and Flores people distributed in South Asia. Their appearance varied, neanderthals had relatively white skin and thick bodies, but were shorter than modern humans. Denisovans were about the same height as modern people, but had darker skin tones. Then the Flores, because he lived in Southeast Asia, close to the equator, had a darker complexion and was short, probably only about a meter.
Modern Homo sapiens came out of Africa and first reached the region of West Asia, where they met the Neanderthals of the time and lived together for a long time. Then there must have been a love story between them. Because most people outside of Africa, modern people, have 1% to 6% of this Neanderthal gene.
About 60,000 years ago,
The D cluster began to migrate eastward along the coastline, and eventually they reached the island of Japan, and scientists measured that the Y chromosome haplogroup of the Japanese emperor of the First Lineage was D type, which shows how wide the D type was in Japan, but at that time there was still a part of the D tribe that continued north to the easternmost point of Eurasia.
Here the E-Group turned westward and returned to the African continent from here in the Sinai Peninsula.
Group C. They started migrating eastward, and they went all the way east along the coastline, and then. Some of them went north to East Asia, and some went south along the coastline, eventually reaching mainland Australia. This is the first time that a claposaur has set foot on the continent of Australia
Then there is the F group, which is very active in genetic mutations near the Iranian plateau,
Successively, the J ethnic group was born. The K race, the H race, and the J race are actually the ancestors of the modern Semitic or Arabs.
H cluster. That is, the Dravidians, who first went south into the Indian Peninsula and later established the Halapan civilization of ancient India.
The K group here has split into the P group.
P group, one migrated to the vicinity of Southeast Asia, and then another part of the P group is dividing into R and Q groups.
The R community is actually the ancestor of the primitive Indo-Europeans, so later the R community, to the west became the Germans, the Celts, the Greeks in the south, the later Romans, and the Slavs to the east, and the Persians to the south. And all the way to South Asia, India, which called itself the Aryans, gradually replaced the Dravidians and created their own civilization
When modern Homo sapiens spread westward, it also created great oppression on the living space of Neanderthals, causing Neanderthals to migrate westward, and finally the last Neanderthal was in the Strait of Gibraltar, sighing and depressed.
Then another branch of the P population, the Q group, reached northeast to the easternmost part of Eurasia.
Then this side of Southeast Asia, the P group, divided into no groups, about 40,000 years ago from the Hengduan Mountains into East Asia, and merged with the early C group.
In the process of spreading north, they met the Denisovans who had already lived here, and then they also produced some love stories, so basically the modern people of East and Southeast Asia throughout East Asia contain 1% to 3% of the Denisovan genes. Especially for Tibetans, this gene for high altitude climate tolerance is very much related to the Denisovans.
But later the Denisovans suffered the same fate as the Neanderthals, and their living space was squeezed by modern humans and eventually died out in the Siberian wasteland
Then the N group of the NO group also went all the way north, divided into two branches in North Asia, one to the west, over the Ural Mountains to northern Europe, and one to the east to the eastern tip of Eurasia, ready to enter the New World.
Then the O population diverged into O1 and O2 in East Asia.
O2 spread north and westward, adapting to the dry and cold climate in the north, forming the later Xiqiang and Xirong people. O1 developed in the south, adapted to the warm and humid climate in the south, and gradually multiplied and formed the later Miao, Dong Dai and other tribal groups.
Then it also spread outwards, and Japan also had a lot of O1s. Also migrated to Southeast Asia, as well as to the Pacific Islands and even Australia has an O-type division.
As these modern Homo sapiens gradually expanded in Southeast Asia, it eventually led to the demise of the Flores.
And then one of the O groups also went north to the eastern tip of Eurasia.
Around 15,000, before the end of the last ice age, when the White Collar Strait was still a land, these groups crossed the White Collar Road Bridge and entered the American continent. Then it spread across the American continent, so we can see that the appearance of the current Native Americans is still somewhat similar to that of us East Asians.
By about 12,000 years, the last ice age was over. As sea levels rise, the white-collar road bridge becomes a white-collar strait, and the old and new continents are cut off. It was not until 10,000 years later, during the Age of Discovery, that the two continents resumed contact
This is a rough migration process of modern Homo sapiens over the past 70,000 years. Very roughly, human migration must be a very complex process, and there are many causes and conditions that affect it. In the end, such a colorful world is formed, and it is also a world with endless problems, but all the goodness comes from the goodness and justice in human nature, and all the problems come from human beings' own ignorance and arrogance # cultural inferiority # # squinting eyes # # racial discrimination # #人类迁徙 #
