There is no doubt that humans evolved from primitive apes, and it can be said that the evolution of humans can be traced back to 15 million years ago in the forest apes.
Although the earth is now full of human footprints, divided into three major species: Caucasian, black and yellow, in fact, they are all descendants of the same ancestor and belong to the same species, and there is no reproductive isolation between them.
The evolution from apes to humans was not a rapid development, and there was natural selection in between.
It was only through environmental influences that humans slowly evolved into what we are today. <>
Archaeologists have found that the earliest humans were between 3.80 and 3.6 million years ago, but they were not real humans, and in the process of our human evolution, Homo erectus, Homo erectus, Mauritan man, Homo sapiens, etc. are actually our human brothers and sisters.
In the process of changing the earth, we humans evolved by natural selection in order to adapt to the environment, according to scientists.
It was found that the skull of the 40,000-year-old "new man" was raised, the brow ridge was almost gone, the jaw was retracted, and the chin was obviously almost the same as the human form of us now.
The big difference, the "new human" fossils are distributed in Asia, Africa, Europe and other continents, which shows that human beings have gone to the world at that time. <>
It has been found that we humans arrived in the Americas about 50,000 years ago, and we humans have been there since then. But there are still archaeologists who are skeptical of this claim, and there is no definitive answer to the fact that humans arrived in Australia 40,000 years ago based on the fossils we found.
In the late primitive period, Homo sapiens was formed, and almost modern humans were formed, roughly dividing them into the race.
Caucasian and Negro races.
The three major races, of course, there are individual places where the Australian race.
Divided into the fourth largest race, there are actually several smaller races, but due to some environmental influences such as natural selection and historical conditions, some races have naturally been eliminated, leaving behind the current human race. <>
In general, all the current human races are the same ancestor, all of them are descendants of "Homo sapiens", and there is no reproductive isolation, but some changes in the characteristics of some races that affect themselves because of the environment!

Non-Mediterranean Caucasian and partially yellow (including Han) are the closest blood races, even closer than the Tunguska of the yellow race or some of the yellow people in South Asia. The Finns of Northern Europe are academically known as the Chinese Finnish species, especially the Han Chinese. Not to mention that molecular genetics has long confirmed that all people in the world have a common ancestor.
-
The fact that the yellow race and the white race are the same ancestor, and the different skin colors do not mean that they are not the same ancestor, but only show the external form of our ancestors in the process of evolution, in fact, all species on the earth have a common ancestor.
-
The world's human genetic map proves that ancient ancestors were common ancestors, and now the difference between yellow and white people, and the difference within any white race is very large.
99% of human genes are dyed.
The autosomal parts of Europeans, ENF, WHG, and ANE, are mainly these three major categories, which can be said to be very heterogeneous.
Middle Eastern autochroma, basal eruasia plus CGH.
South Asian autosome, ase.
In this way, white people are different ancestors.
The yellow race in East Asia, Southeast Asia, North Asia, and Oceania is almost all EE, while the Indians are very unique and genetically very far from other yellow people.
-
According to records, the yellow race and the white race are not the same ancestor. That's why there is a difference between the yellow race and the white race.

Don't think that humans have a single ancestor! I think the evolution of species may have something to do with the environment, that is, the entire environment of the earth! Warm periods, hyperaerobic periods, glacial periods, etc.!
Including the size of the suction between the Earth and the Moon. and even the movement of the earth's tectonic plates. Also possible with the intensity of the sun's radiation!
Supernova giant explosion and so on! Inverted as radiation to a species. For example, a mutation in one of a person's genes may lead to human population differentiation!
So I think we humans may have different ancestors on all continents of the earth at the same time! For example.
The black people of Africa are dry in the tropics of the earth! Two million years ago, the Earth was in the Quaternary Ice Age! They have abundant food to eat!
No worries about the alternation of cold and heat, no cold, no need for warm clothes, as long as you avoid the pursuit of fierce beasts! to survive! As a result, their ability to adapt to survive develops into increased fertility!
I improve my muscle strength and run well!
And the yellow East Asian people were born in the temperate zone of the northern latitude! There are four seasons of change! To survive in winter, you must be able to keep out the cold and use fire!
Will raise animals for training! For growing food! Will plant linen, cotton and other fabrics will make clothes!
Fishing with nets! And there is the Qinghai-Tibet Plateau constantly uplifting, and the sky is even colder! Therefore, before the ice age, we have the ability to protect against the cold!
Can collectively survive the ice age! There is also the Yangtze River and the Yellow River! Spread quickly south after the ice age!
Under the natural conditions of the south, the agricultural civilization developed rapidly, and ate cooked food! Clothes to wear! Brain volume develops rapidly, and the fetal period is prolonged.
Extended early childhood becomes prolonged! Loss of body hair. Two pieces of the little toe bone are missing.
Not good at running! It's all determined by the survival needs of the yellow race. It's the evolution of the human race!
It can't have anything to do with the people! Therefore, hard-working East Asian Chinese are the smartest! IQ number one!

Yes, the common ancestors were people who once lived on the African continent, only in the end due to the separation of the Eurasian plates, the population was isolated.

In a broad sense, the earth human race is the same ancestor, but after all, it is Zhao Qian, Sun Li, so it is not a line in a narrow sense.
The god system is divided into three major systems: dragon, phoenix and unicorn, and in the era of human and god cohabitation, the black-eyed and black-haired people who worship the heavens return to the middle earth of the dragon's territory, so they are called the descendants of the dragon. The Caucasian people believe in angels, and the birdmen bring wings to the phoenix line, and they are the human race on the territory of the phoenix line.
Huaxia holds the theory that the gods are the ancestors, because the celestial system is in the hands of Nuwa (dragon system) to upgrade the evolution technology, and before the gods, only the Huaxia human race has passed the cultivation of the truth, and the great flood is the price that has to be paid to upgrade the life system that all living beings rely on. The West, on the other hand, holds the theory of man-made lambs, and the Great Flood is God's punishment for destroying the world and man.
After the great flood, Xia Boyu's fief Xia was the source of Chinese civilization, and the fief Xia bloodline was Zhuxia for Huaxia, and the fief Xia was on the Qinghai-Tibet Plateau. And the race of the West after the Great Flood is judged to be an ark that has escaped the water. So Huang Bai is not the same ancestor.

Whites and blacks are one ancestor, originating in Africa; The yellow race originated in China and are different ancestors.
-
Yellow people have nothing to do with blacks, whites.

Genes are different, evolution is different, and IQs are different.

The main difference between the yellow and white races is bone characteristics, pelvic index, head index, and body proportions. Skin tone should be the last thing to consider.
It is unscientific to distinguish by skin color. Skin tone is susceptible to external influences. Caucasian Mediterranean skin tones are similar to those of yellow East Asian types.
Therefore, the Chinese are yellow, and the Iranians in West Asia belong to the Caucasian race, because the Iranians have a long head type, a well-developed eyebrow arch, a high nose bridge index, an inconspicuous palate, a deep contour, and long limbs, so they are Caucasian. The Chinese are mainly short-headed, with a generally low nose bridge index, underdeveloped eyebrow arches, generally prominent palate, and short limbs, so they are yellow. In general, white and black, yellow and black are easier to distinguish, but there is little difference between yellow and white **melanin, especially in Central Asia, and the white people in the Middle East may be slightly darker than the yellow people in East Asia.
Therefore, at this time, the bone index and body proportion play a decisive role in distinguishing between yellow and white. Of course, there are also ethnic groups that are of mixed race. For example, the Turkic system is a mixture of the Caucasian Alpine type and the yellow Siberian type.

First of all, their colors are different, but their face shape is also different, and if you have a white face, your eyes are more sunken.
-
The most obvious difference between these two types of people is the difference in skin color, and the Caucasian people are taller and have different eye and hair colors, which are easy to distinguish.
-
Yellow race: black hair, black eyes, yellow **.
Caucasian: Blonde and white**. Of course, there are many differences.
-
In addition to skin color, eye color, hair color and shape.

1. Different titles: (1) White race, also known as Europa race and Caucasian race, refers to a race with specific physical characteristics, which is a concept of physical anthropology. Caucasians make up about fifty-four percent of the world's population.
2) The yellow race, also known as the yellow race, the Asian American race, the Mongolian race, and the Mongolian race is one of the four major human races in the world. It is the second largest of the four major human races. Yellow people make up about 37% of the world's population.
2. Different physical characteristics: (1) European Caucasians in the Mediterranean region have white complexion, heavy body hair, deep eye sockets, low cheekbones, flatter jawbones, tall noses, thin lips, curly hair, reddish-brown and golden-yellow in childhood, and blue-green iris. Caucasians in the Mediterranean region have darker skin than the former, and their hair and iris are mainly brown and reddish-brown.
South Asian Caucasians have darker complexions. (2) The skin color of yellow people is white or light yellow, most of them have black hair, dark brown or light brown eyes, and only a few are blonde and blue-eyed. Black and straighter hair, less beard and body hair, and less body odor.
The chin is not protruding, but some people are pointed, while others are flattened. The nasal width is medium, and the nasal apex index is medium. The eye is medium-fissure, brown iris, the upper eyelid fold is well developed, and most eyes have an epicanthal fold covering the lacrimal mons.
The spade-shaped structure of the tongue surface of the upper incisors is also one of the distinguishing features of the yellow race. 3. Different distribution ranges: (1) White people are mainly distributed in Europe, North Africa, West Asia, Central Asia, South Asia, North America, South America and Oceania.
The native places of Caucasian people are Europe, North Africa, West Asia, Central Asia, and South Asia. Whereas, the Caucasian people of the Americas and Oceania are mainly of European descent. (2) Yellow people are mainly distributed in the Urals, East Asia, North Asia, Northeast Asia, Siberia, North South Asia, Southeast Asia and a few in the Americas and Oceania.

Neither the yellow nor the white came first, but the brown first. The "species" here refers to the species of skin color, not the human population, in fact, there is always only "one kind of person" in the world.
First of all, the color of human skin is determined by a combination of genes. Different people have different skin tones, which is entirely determined by the combination of genes.
Second, the likelihood of a human skin color variety depends on the human gene pool. With the formation of countries and nations, this gene pool has gradually become missing from the initial integrity. For example, the average Chinese and the descendants of the Chinese must have black eyes, because our nation has lost the genes for other colors of eyeballs.
So if a Chinese is combined with a Caucasians, there are two possibilities for the ** and eye color of their offspring.
Therefore, Caucasians and yellow people are formed for this reason, because of various elements such as national borders, geography, language, aesthetics, etc., human beings as a whole always tend to combine with people close to themselves, which leads to the lack of gene pool information.
Therefore, whether it is a Caucasian or a yellow person, their ancestors should be people with a complete gene pool, and it is possible to have both white ** children and children of other skin colors when combined in pairs. If we extrapolate backwards from the existing human gene pool information, the ancestors should be brown people.

First there were yellow people, and then the yellow people migrated, and some of them evolved into white people when they reached colder places, and some of them evolved into black people when they reached hotter places!

Human beings have developed and evolved on the earth for millions of years, from ancient times to the present, human footprints are all over the world, it can be said that the distribution of human beings is very wide, because different natural living environments will also produce different traits, the most typical is the difference in color, but this does not mean that yellow people, black people and white people are different races, modern humans are the direct descendants of Homo sapiens 200,000 years ago, so they belong to the same species, and there is no reproductive isolation between each other. In fact, it's not just yellow and white people who have the same ancestry, but so do black people. Differences in skin color are not a factor that distinguishes ancestors, it is only an outward form in a long evolutionary process.
Not to mention human beings with different skin colors, all species on the earth have a common ancestor, such as humans, pigs, cows, sheep, etc., of course, in a broad sense, people, pigs, cows, sheep and other things are the descendants of primitive life more than 3 billion years ago.
<> mainstream theory in modern science is that the common ancestor of humans came from Homo sapiens, which emerged from Africa more than 100,000 years ago and migrated to other continents such as Europe, Asia, and of course, Oceania over a long period of time. The Amerindians and Mayans also share a common ancestor with the mainstream human civilization, not as some on the internet claim"The Mayans are aliens"!
Science is rigorous, and conclusions cannot be drawn casually. The reason why different groups of people have a common ancestor is mainly based on human genetic research, such as the dyeing system, which can be traced back to our human ancestors based on the genes of modern people, and archaeological evidence. There is also clear and direct evidence that there is no reproductive segregation between people of different skin colors, that is, people of all skin colors can intermarry and reproduce, suggesting a common ancestor.

"Metal" and "conductor" do not mean the same thing.
Metal is a substance with lustrous (i.e., strong reflection of visible light), malleable, easy to conduct electricity, heat and other properties. The above properties of metals are related to the presence of free electrons in metal crystals. In nature, the vast majority of metals exist in a chemical state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. >>>More
