Cross-racial interactions have always been full of surprises. In addition to the differences in appearance caused by eyebrows, eyes, mouth, nose, skull shape, and skin color, there are also slight deviations in the internal physiological processes, which in turn lead to different perceptions of early maturation, late maturation, and premature aging.

There are differences in perceptions of late aging. Therefore, Asians think Africans mature early, and Europeans think Asians are resistant to aging.

For the same reason, the use of drugs across races has always been full of dangers. In the 20th century, chemical pharmaceutical technology in Europe and the United States was far ahead. The special drugs they developed in that era were not effective at all when used in East Asia.

This happened before. This also forced the independence of drug research in East Asia.

From the perspective of the process of human evolution, after leaving Africa, the farther the human species travels, the stronger their ability to adapt to different environments. From this perspective, American Indians should be the most powerful human race. From a physical perspective

From a different angle, maybe American Indians are really tough.

But from the perspective of civilization development, the connected Eurasian and African continents, due to their vast territory, topography, and complex climate, have provided conditions for different civilizations to develop independently and then merge and merge. Looking at the evolution of history from the standpoint of modern civilization,

Being physically the strongest really means nothing.

Moreover, the Indians' physiques were not really strong against the smallpox brought by Europeans from Eurasia and Africa, so their immune systems could not deal with it.

The Eurasian and African continents, which are larger than the Americas, not only provide richer resources, but also richer infectious diseases. Similarly, during the evolution of human beings, they not only created civilization, but also developed immunity.

The Indians on the American continent received smallpox, and corpses littered the fields. In return, they responded with another infectious disease, syphilis.

In fact, humans have not evolved immunity to infectious diseases. All living things face diseases in the same way: those that remain after death have special mutations that allow them to ignore germs or viruses, and they will die if they catch them

The people left the land and property, and then reproduced their descendants; the descendants were naturally not afraid of those germs and viruses, so the population exploded, returning the number of humans to the state before the disease was prevalent. Just like Europe after the Black Death era.

The problem is, no one wants to test whether they will die. It is also possible that when a strange serious disease comes, there will be no mutations that can allow a few people to survive in the entire area. Well, then they will all die together.

.

The factors that have contributed the most to human evolution are, first, luck, and second, population size.

The generational change of primitive people occurred when they were in their teens. The remains excavated died at the age of eighteen. The generational change of modern people is uncertain.

In the early years of China, there were so many people in their thirties who had not had children. Later, with the birth tax and the help of childcare centers, the number was finally reduced to those in their twenties.

The human reproductive cycle is so long, it is unrealistic to rely on mutations like winning a lottery ticket to overcome all difficulties.

The greatest achievement of human evolution is not a strong body, but civilization. With civilization, we can finally cheat all the way. When the Black Death broke out in the west of the Eurasian continent, the east was not so affected. In ancient times,

It is not that the civilization of the Central Plains was not exposed to infectious diseases. "After a major disaster, there will be a major epidemic" was a concept passed down from that time. The Eastern world was more civilized at that time.

Then, civilization and mutation began to conflict again. In the presence of beneficial mutations, it is in line with the "direction" of evolution that all other people die. And the choice of civilization is to let as many people survive as possible. The power of civilization brings

The population is expanding, and in the huge population base, various mutations coexist in the world. The advantageous mutations are wiped out by civilization, and the disadvantageous mutations are made up for by the power of civilization. Fools' families give birth to fools from generation to generation in order to pass on the family line, and hemophilia continues in the world.

It was passed down from generation to generation among European nobles.

Therefore, the development of civilization is actually crazy. In the era of class struggle, all human beings on the earth are like idiots.

Unless classes are eliminated, family planning is done like in China. Do you want to know about the national birth tax? Do you want to know about the maximum number of children?

Also, do you want to know about the personal protection of mutation carriers? Do you want to know about the safety level of the working environment?

If Lan Ze or Mr. Lan were sliced ​​up, the major and valuable mutations they carry would be able to sweep through every corner of the land of China through technological means. However, this kind of barbaric method, the leader of human progress, I, the Great China, disdains.

The so-called mutation is based on the random and uncertain changes in genetic information. No one can be sure what impact the mutations that experts have determined to be beneficial to survival will have on society when they actually spread throughout human society.

Since the evolution of human beings, the physical body is just a carrier, and the most valuable thing is civilization.

If some kind of wonderful genetic mutation makes human skin tougher, when operating a machine tool or a chainsaw, the hand would be broken accidentally with just one cut, but now it would take three cuts; a side effect would be that the personality becomes slightly colder.

What would happen to society if the world was full of people like this?

A society can tolerate the existence of a certain number of members with "indifferent" personalities. However, in order to maintain the continuation of civilization and the soundness of the social network, there is a limit to the tolerance of "indifferent" individuals.

In addition to the obvious physical benefits of any valuable mutation, no one knows what it will bring to all mankind.

The formation of mental ability is affected by various factors. If a person has an indifferent personality, do you know whether it is because his dog was murdered, or because his skin is tough? If a person fails in the exam, do you know whether it is because he stayed up late to work and lacked sleep for a long time, or because he has tough skin?

China's approach to dealing with valuable mutations is to use natural reproduction to expand samples and conduct long-term observations across generations.

This is a far-sighted and large-scale systematic project. It is impossible to have clearly visible results within one or two generations.

Just expanding the sample is not easy. Lanze's four children are all sons. Among these four sons, there is only one mutation carrier, Wheat.

This is just passing on the mutation in his family, not expanding it.

Lanze agreed on a handover time with the female caregiver, gave him his home address in Maritime City and permission to open the door. Then he watched her take away his three good sons.

Monster Wei had not boasted enough. When the children were present, he spoke more reservedly; after the three children fell asleep, the two adults became even more uncomfortable talking.

The monster Wei had to lower his voice in everything he said. Lanze kept looking at his sons and couldn't pay attention to what the monster was saying.
