[Civilization has developed to this day, and there have been many sages of the Shepba people who have established various biological testing grounds, including insects and small animals, which are one of the few remaining species on Mars.

Even in order to better achieve the purpose of the experiment, the sages of the Muba people also used these small animals as a blueprint to artificially breed a group of animals with more developed brains, wisdom instincts and social activities for experiments. 】

[Countless biological experiments have shown that we are special, and we cannot understand that those male animals will fight to death for a mating right.]

If you can't understand that their survival needs are solved, there will be a bunch of messy desires, and when these new desires are solved, there will be new and more demanding desires.

Even for these things that do not involve survival, do not affect them, and can live well without them, they will risk paying the price of their lives, what a ridiculous thing! 】

[We can't understand...... Perhaps this is the essential difference between producers and predators. 】

[After these biological experiments, coupled with the use of the Living Planet model to calculate how low the probability of a producer becoming an intelligent life is, we really realized that we are a special ......]

[We are Muba people, we are photosynthetic intelligent life, we are the most special and greatest miracle of life! 】

[So when the last coal mining area on the planet was hollowed out, the financiers and sages of the Muba civilization also began to gather to discuss the future of the Muba civilization. 】

[Our financiers are not so much financiers as civilized managers.

Although they use capital to integrate social resources and borrow the economic and trade system for their own interests, as a photosynthetic life, in addition to satisfying the needs of survival, our other desires and needs are very small.

So even with one of the most powerful weapons in civilization, these financiers don't really make sense to exploit the lower classes after satisfying their own survival needs. 】

[The survival elements of the Muba people, carbon, water, light energy, water resources are still very abundant, the light energy sun has not been extinguished, and the only thing that really has a lot for the Muba people is carbon. 】

[The total amount of carbon determines the population of the Muba people. 】

[Our lifespan is very long, according to the record of the longest lived one of the shepherds lived for 13,877 years, our reproductive offspring usually reproduce once every 3 years according to physiological habits, and give birth to a seed of life in the canopy of the tree half-buried in the ground, providing some light, sunlight, carbon gas.

Of course, once necessary, we can also reproduce once a year, no more than 3 offspring each time, and the reproduction can be asexual autologous reproduction, or we can combine with other herdsmen to ask for some genetic media.

After understanding the existence of biological genes and the theory of genetic evolution, in order to ensure the perfection and stability of the Muba people's genes, everyone gradually adopted the method of non-autologous reproduction to give birth to offspring. 】

[Civilization is developing, thinking is progressing, there are those who want to reproduce, and there are those who do not want to reproduce, civilization has developed to this extent, and intelligent life has many ways to not suppress its own physiological instincts and at the same time can not have offspring. 】

[These factors determine that our system must be cautious, and it must be very suitable for the actual situation of the Muba people, which will not make the people feel depressed, nor let the Muba civilization lose its vitality, and at the same time, we cannot let the people reproduce wildly, which will cause a carbon crisis again and collapse the entire civilization. 】

[Therefore, after several years of discussion, a large number of Muba people were consulted, and a carbon-based civilization system was born. 】

[After calculating how many adult shepherds can meet the needs of the total amount of carbon on Mars, the new Muba civilization system stipulates that when the number of Muba reaches 80% of the total carbon, all Muba people will limit the birth of offspring, retaining 20% of the redundancy as the driving vitality of civilization.

That is, after the Muba people have made a major breakthrough in the existing technology, explained the existing theory, and made a certain contribution to the development and operation of the Muba civilization, they will obtain the reproduction limit of their offspring. 】

[This system ensures that the number of Muba people will never exceed the capacity of the environment, because there will always be Muba people who die, and the 20% redundancy will never be spent.]

At the same time, in order to avoid the habit of the Muba people not to reproduce offspring, but when the number of civilized population drops to less than 40%, the use of biotechnology is allowed to reproduce and inherit artificial offspring......]

"This ...... Is such a system reasonable? Professor Hill was a little stunned, the modern civilization system of the Muba people is simply challenging the human imagination.

"It is certainly a ridiculous system for us humans, but it is the most appropriate system for the Muba civilization."

Lu Yi looked at the implementation of this system on the screen, all the Muba people began to move to the Muba civilization in the equatorial region for more sunshine, and while the doubts of the equatorial coal mine belt were solved, he also shook his head and said:

"Muba people have no concept of family affection, human father's love and mother's love do not exist in them, they are producers, and they are the absolute overlords tens of millions of years ago, so evolution has not imprinted the instinct of father's love and mother's love in the genes.

In their eyes, their offspring are not much different from the Muba neighbors next door, and even because of the thoughts and ideas of intelligent life, they may resonate with the thoughts of their neighbors, so that their relationship with their neighbors will be deeper than that with their offspring or siblings.

What they have is only the reproductive instinct of living beings, but because they live for 10,000 years, this instinct is weaker than that of us humans. ”

The concept of human affection, father's love and mother's love, and filial piety are determined by the social environment and education in modern times, and the root is derived from genetic instinct.

Because in the primitive period, human ancestors were always threatened by the outside world, and in this context, the survival rate of the offspring of parents who chose to protect their cubs was several orders of magnitude higher than that of the offspring raised by parents who did not choose not to protect their cubs.

In the long run, the cub protection gene is deeply ingrained, and the human who does not have the cub protection gene is almost extinct, gradually disappearing from the human genetic map.

The root of father's love and mother's love is in genes, and the root of filial piety is also in genes.

As non-apex predators, human beings have all kinds of natural, natural and man-made disasters around them before the development of modern civilization.

Many natural disasters and man-made disasters can be detected in advance, so the experience of the elderly is very important at this time, which determines the survival rate of human beings who respect filial piety to the elderly, which is much higher than the survival rate of those who do not respect filial piety.

These are all instincts formed by natural selection in the long history of human evolution, and these instincts can make the race better inherited and reproduced, and then in the era of civilization, under the influence of this instinct, a kind of thought, a concept of civilization, and a kind of social universality have been formed.

As for the shepherds, they have never needed such an evolutionary choice, and it would be good if they didn't slaughter the planet and have another mass extinction, but they would also have the instinct of protecting cubs and filial piety because of external threats.

The need for offspring to reproduce is inversely proportional to the length of the life span of the organism, the shorter the lifespan of the species, the more able to give birth and the more they want to live, and the longer the life span of the species, the lower the desire to reproduce, the less they want to give birth.

This law of reproduction is not only embodied in animals and plants in nature, but also in intelligent life such as human beings.

A hundred years ago, the average life expectancy during the Republic of China was 35 years old, so when the teenagers were just physiologically mature, those little Lori got married, and at the age of 17, she may be the mother of two children, and then she was born until five, six, seven or eight......

In recent decades, the average life expectancy of the people has exceeded 70 years old, not only the legal age of marriage is required, but also the time for people to get married and have children is getting later and later, in recent years, it is 25 is still early, 28 is just right, 30 is not too late......

Among them, there are reasons why the people attach more importance to the concept of eugenics, there are reasons for cultural influence, and there are reasons for social pressure, but it cannot be denied that there are factors of genetic instinct.

For the 10,000-year life expectancy of the Muba people, the breeding demand can be imagined how low, if you are in a good mood, then follow the physiological instinct to reproduce a child in 3 years, and if you are not happy, then we will not give birth.
