Zuo Dajun caught up with Fan Xiaoming's footsteps with a smile, and said with a smile: "If you don't leave first to busy yourself, anyway, these can be visited at any time, and the most important artificial uterine technology has also been seen, so it doesn't matter if you follow it." "The main purpose of their visit this time is the artificial uterus technology, and now the visit is basically over, as for the later visits, it is okay to visit.

Xu Zhengping nodded and said, "Yes!" You can go to the National Astronomical Observatory to find your partner now, and the wedding will be held the day after tomorrow. Su Zhe smiled and said, "Why don't you leave first, and I'll go back and visit with you again." Bauchi was smiling and nodding,

"Now my sister-in-law is probably excited, it's better for you to go over early." Fan Xiaoming smiled awkwardly and said: "That, my subject is busy, I won't get off work in three hours, it's too early now, let's continue to visit, these calves can't see the completion of development, and the sheep can't see it, but the rabbits and mice can see it." "Cows and sheep have a longer pregnancy cycle, while rabbits and mice have a much shorter pregnancy cycle.

Zuo Dajun's face was surprised,

"What! There are rabbits and rats here, and I can understand rabbits, but what is the matter with rats? "This is a space ranch, if he puts rabbits in the space ranch, he can understand, after all, even if rabbits are not reproduced through artificial uteruses, their natural reproduction is very fast, whether it is rabbit fur or meat, it is also a good production.

But the rat is what he can't understand. Relatively speaking, there are many people who eat rabbit meat, but there are too few people who eat rat meat.

Fan Xiaoming smiled and explained: "Not only rabbits and mice, let me say so!" But where there are animals on the grassland, there will be them here, after all, the space ranch simulates the environment of the grassland, and since it is a simulation, it is necessary to carry out a comprehensive simulation. "Space ranches simulate the natural environment of the grasslands on Earth, from microorganisms to plants to animals, so it's not difficult to understand that there are rabbits and mice.

"That's it! I see! Zuo Dajun smiled,

"Then let's hurry up, I want to see how rabbits and mice cultivated in artificial wombs are different from those bred naturally."

"What difference can it be, of course it's exactly the same." Xu Zhengping said with certainty. Fan Xiaoming said with a smile: "What we look at next is the breeding of sheep, followed by the breeding of other mammals such as rabbits and mice, in fact, there are still a few mammals bred by artificial uterus in the space ranch, and the No. 1 ecosystem is complete, as long as there are mammals on the earth, no, it should be said that as long as there are animals and plants on the earth, the No. 1 ecosystem will conduct research and breeding, such as our long-term tigers, lions, giant pandas and the like." Zuo Dajun nodded and said: "I understand this, the No. 1 biosphere simulates the ecology of the entire earth, and there must be one biosphere No. 1 on the earth." "Don't look at Biosphere 1 as small, but Biosphere 1 simulates the entire ecology of the Earth.

Not only Biosphere 1, but also Biosphere 2, which is 300 kilometers away, is also used to simulate the ecology of the entire planet.

As for the research on the No. 1 and No. 2 ecosystems, they are actually preparations for us to build a living environment for human beings in the universe in the future.

For example, the second earth that Qingda is researching, and the transformation of celestial bodies by Yanda, which need the support of research data from the No. 1 ecosystem and the No. 2 ecosphere.

The ecology of the earth is complex, and there is a process to study clearly. Xu Zhengping said with a smile: "That's the case, there is a long way to go to study the earth's ecology, but there are many people who can't stand it!" This is related to the creation of a living environment for human beings outside the earth, and everyone attaches great importance to it. "The ecology of the earth is quite complex, and if you want to understand the ecology of the world, you have to invest a huge amount of manpower and material resources.

Resources and energy can be invested sustainably, and if they are poor, they are also poor in manpower. Although there are not many more people engaged in scientific research now than there were a year ago, there is still less demand for research.

In the past, there was no way to do that, because of the limited resources and energy, and a lot of manpower had to be spent on ensuring the production of subsistence materials.

Now that's a different story. Ninety percent of the manpower has been liberated from the production line, and the vast majority of them are directly or indirectly involved in scientific research, but even so, there are still fewer of them.

The current situation is that there are abundant resources and sufficient energy, but there is a serious shortage of manpower. The ecology of the earth needs to be studied, which means that the entire operating mechanism of the earth needs to be studied, plus the development and research of the solar system, as well as those cutting-edge technologies, and finally the study of extrasolar space.

There's so much to study, too many projects to study. But there is a serious shortage of manpower.

For now, because the human power cannot keep up with the demand, it severely limits the development of science and technology and the development of the solar system.

If the proton fusion device is successfully developed, it means that mankind has mastered the technology of controlled nuclear fusion, and mankind will have the ability to travel interstellar.

At this time, the shortage of manpower is even greater. It is for this reason, coupled with a long-term vision for human development, that the population increase plan has emerged.

The increase in population is not only related to the current development, but also to the long-term development of mankind. Fan Xiaoming nodded and said, "Yes!" Compared with the past, there are not too many people who study the ecology of the earth, but for the projects that need to be studied, there are still too few of them, even if it increases by a hundred times, it is not much. ”

"This is true, there are too many unknowns in the universe waiting for us to study, even if people estimate that there are still endless projects." Xu Zhengping smiled,

"It's this population increase plan, even from now on, the first wave of research will have to wait for more than ten years, but there is no way to do it, but then again, we still have to wait for this time, and in more than ten years, our science and technology will be accelerated because of the explosion in the number of people." Zuo Dajun said with a smile: "Of course, as far as our next generation, whether it is education or others, they are definitely better than us, as for the burying of talents, it will not happen, quality plus quantity, even if as time goes by, the difficulty of scientific research is getting bigger and bigger, but the new scientific research manpower is also an astronomical number, and the number of people will reach 100 billion in 60 years, conservatively speaking, half of them will join the work of scientific research, and 50 trillion people will engage in scientific research, what kind of situation is that." "For now, repetitive tasks like production are being done

"Robots" have been replaced, and what can be done now is either service-oriented positions or scientific research, and the vast majority of them are engaged in scientific research.

As for those who lie flat, they are a minority after all. This is the case now, and it is estimated that it will be even more so in the future, except for scientific research, which is innovative and the like, other jobs will be used

"Robot" instead. This is already an established fact. The further we go, the higher the proportion of people involved in scientific research.

Fan Xiaoming smiled and said: "Science and technology are developing explosively! Seriously, even if there are so many people involved in scientific research, it is unrealistic to figure out all the rules of the universe in a short period of time. Zuo Dajun said disapprovingly: "If we want the environment, we will create the environment." Anyway, there is nothing wrong with having more people, we have resources and energy, plus enough people, as long as we persist in research, we will be able to figure out the nature of the universe sooner or later. ”

"This is not necessarily, some people find that it is really not good to have more people, it depends on the opportunity." Fan Xiaoming explained,

"What's more, the further you go, the more difficult the research becomes, but then again, but in any case, it's right that we insist on doing research, not that the tactics of the crowd are not good, but also depend on the opportunity." Fan Xiaoming and Zuo Dajun said word by word.

Soon, Su Zhe and the five of them went to the sheep cultivation area under the guidance of the narrator. Xu Zhengping saw that Fan Xiaoming and Zuo Dajun were talking endlessly, and reminded: "You two are okay, don't quarrel, visit well." Hearing Xu Zhengping say this, Fan Xiaoming and Zuo Dajun stopped.

The five of them began to visit the sheep cultivation area, which is actually the sheep cultivation production line, which is similar to the cattle cultivation production line.

The same starts from the proliferation culture of ovocytes and spermatogonia of sheep, and finally the blastocyst of sheep is implanted into the artificial uterus.

Seeing the end, Zuo Dajun said with a smile: "The front ones are almost the same, and they even say that they can't see the difference, the difference is that in the end, the artificial womb of this sheep is smaller than that of a cow." "The contrast between the two is much worse.

Fan Xiaoming smiled and said: "What you said, how big is the sheep, how big is the cow, and the newborn calf is as big as an adult sheep, how can the two compare, and you will be even more surprised when you see the size of the artificial womb of the rabbit and the mouse." Zuo Dajun smiled awkwardly, looked at the lamb in the artificial womb that had not yet developed and grown, and said: "It's moved, this lamb has been fully formed, and it is estimated that it will not be long before it can be born." As soon as the words ended, the narrator explained that the first batch of sheep would be born in three months.

Hearing this, Zuo Dajun asked with a puzzled face: "The cattle and sheep here have not yet grown up, where did the cattle and sheep on the grassland come from?" Xu Zhengping shook his head and said, "Do you still need to say what you asked?" Those were transported directly from the earth, and such a large space ranch has been built, and it is not easy to transport some cattle and sheep. ”

"Okay!" Zuo Dajun smiled and said,

"Let's go and see rabbits and mice, and I guess we used to be able to see rabbits and rats born." Soon, Su Zhe and the five came to the rabbit cultivation production line.

The beginning was the same, and the five of them took a casual look and came to the final artificial uterine area. From the newly-implanted rabbit's blastocyst at the beginning, to the embryo formed, to the rabbit moving around in the artificial womb.

When I saw the end, I saw that a lot of artificial wombs were taken by robots. According to the narrator, the rabbits in these removed artificial wombs have already developed and will soon be able to be born.

Su Zhe and the five of them followed one of the robots to another area. In this area, there are so many robots delivering these little rabbits.

Su Zhe and the five of them looked at the robot in front of them a little bit of operation. The robot opened the artificial womb and removed the rabbit from it, and after a period of processing and cleaning, the baby rabbit was placed in a small incubator.

The incubator containing the newborn bunnies was sent to another area. There are a large number of little rabbits in this area, and these little rabbits are screaming, and there are also a large number of robots taking care of these little rabbits.

Zuo Dajun looked at the little rabbit in front of him who had just been born and had not yet opened his eyes, and said with a smile: "This little rabbit is so cute...... As for the rabbit's artificial womb, it is really small, which is the size of a thermos. ”

"The rat's are really small." Fan Xiaoming reminded with a smile. Zuo Dajun nodded and said, "I guess so...... Are these born rabbits going to be raised here for a period of time, and then whether they are released directly to the grassland? ”

"It's going to be raised for a while, but not here." Fan Xiaoming pointed to a robot holding a small rabbit in his hand and said,

"We followed the back of the robot and knew that these newborn rabbits would only stay here for a while, and in the process, the rabbits would be examined and blood taken." Zuo Dajun was a little puzzled,

"I can understand what this blood draw is for?" Bao Qizheng, who was standing next to him, explained: "The genetic material is used for sequencing, and part of the blood sample of the rabbit will be retained, in fact, you can know when the rabbit is born when you pay attention to it, and the umbilical cord blood of the rabbit will also be frozen and retained." ”

"Why sequencing? What do you want to do with these? Zuo Dajun was even more puzzled. Bao Qizheng smiled and said: "Retain the genetic information of the little white rabbit, as for the blood is mainly for research, to put it simply, the genetic material of the rabbit and the relevant life details data, we are not thinking about the present, but also about the long-term future." Xu Zhengping nodded and said: "With the development of science and technology, we want to use the material to directly synthesize the rabbit's fertilized egg through the genetic information left by the rabbit, or all the data information of the rabbit's fertilized egg, so as to develop into a rabbit." Fan Xiaoming nodded and said: "Speaking of which, this is still proposed by Qingda and Yanda, according to their statement, all the data that can be digitized will be possible, and as long as there are enough resources and energy, plus the corresponding technology, the life of the rabbit can be reborn." ”

"This ...... According to this, whether it is a plant or an animal, or a microorganism, as long as there is data information, there is no need to bring seeds, fertilized eggs, etc., you can directly copy it, right! Can it only? Zuo Dajun said and looked at Su Zhe.
