Chapter 411

"These taps are very smart. Can they launch satellites instead?"

"Yes, basically, the transaction terms of the first batch are like this. They chose to use the first batch of trading points and let us launch satellites instead. Other contents are still being discussed slowly. "

Looking at the trading requirements of TEP civilization, Zhang Yuan agreed very much: "it's no problem. The satellite is developed by themselves. We just took a trip and paid little price."

"... however, in a few decades, these satellites launched will be scrapped. At that time, if they still don't develop high thrust rockets, they won't be able to replace them. We will only stay here for three or five years, and then we will leave this star field and can't control them. "

"There's no way... It's already very good." A nearby congressman said: "if they can enjoy the satellite dividend for decades, their world should change to a great extent and pay more attention to this technology. With satellites, the communication of the whole planet will be smoother and the huge planet will be reduced to a world village. "

"Theoretically, any civilization with a little foresight will pay close attention to research during this period of time. Otherwise, when the time comes, a large number of satellites suddenly cannot be used, and the people who are used to satellite technology have to riot. "

Of course, there is no need for mankind to worry too much about how the future TEP civilization will develop.

Human beings are human beings, and TEP civilization is TEP civilization. There is no need to worry about other people's internal affairs“ The regulation of "limited help" has basically been completed.

The "running errands on behalf of mankind" has successfully traded for the historical process of this civilization and a large amount of biological data on the local planet, which is also a business that can make no loss.

Otherwise, it will be very difficult for such a little research robot to research the whole planet.

The historical data and biological data of TEP are also the focus of this scientific conference, especially the traces of enlightener civilization. People have found some clues. This is even more exciting.

A scientist came to the stage. He was the host of this meeting, Professor rocri.

First of all, the scientist played a picture of TEP's native creatures on the screen, including fish, birds and reptiles. In fact, the classification of life on earth is not appropriate. But for better understanding, it is named like this.

"We have to start from the beginning about the traces of the enlightener."

"... due to the high gravity of the planet, the creatures here have evolved strong muscles and hard bones."

The bone density of most animals is very high. Due to the unique hollow structure inside the bone, the overall mass is not too large, which is the most amazing thing for biologists.

"... on this planet, we should not only have enough strength to jump and run, but also evolve to be light enough... So many creatures are slim and slender in terms of muscle structure. The proportion of muscle is far greater than that of fat, and have strong explosive power."

Other creatures look bloated, but they are not.

"... because their outer skin has a thick layer of cuticle, which is similar to foam in the cuticle structure. It is large in size and small in quality. It can effectively buffer the injury caused by falling, not easily fracture, or visceral damage."

"Taps look fat, but in fact they are puffy and of little quality."

Other life forms have evolved exoskeleton structures, mostly small and medium-sized animals. These creatures live in the water like crabs and shrimp. The existence of exoskeleton can provide support for the soft internal organs in the body.

But then again, even if the life here has made some adaptation to the high gravity environment, it is difficult for them to carry out ultra-high-intensity movement like the life on earth, and it is impossible to carry out thousands of kilometers of long-distance migration like salmon.

After all, carbon based life has limits. The energy contained in a unit cell will not be much higher than that of human cells. Even if the evolution is perfect, the life here is still more tired than the creatures on earth during high-intensity exercise.

"Therefore, the explosive power of life here is often very strong, but in terms of endurance, it is generally not comparable to life on earth. People on earth can run marathons for a distance of more than 40 kilometers, but TEP people can't. after running a few kilometers, they start to pant and tired. "

A lot of people like to sleep in the water when they rest, because it can save energy.

TEP people also like to get the most comfortable sleep with the help of the buoyancy of water.

"... this habit has been maintained until now. Basically, every family has a big bathtub, and then sleep in the bathtub during rest."

There's no need to think about drowning in the water. TEP people are good at water. They have huge lung lobes, body muscles and a sponge like cushioning cuticle, which can easily float on the water.

These are all the objective environments on TEP and the evolutionary forms of life under these objective environments.

After introducing these preconditions, Professor Luo asked, "the problem is, since all the life here are species with high outbreak and low endurance, it means that it is difficult for the TEP civilization to evolve into a real agricultural civilization in the most primitive period."

"What is the most important thing to develop agriculture? The first is plants, which need to be cultivated properly. The second is culture, which needs to give birth to farming culture. Third, animals. "

"... the development of agriculture requires livestock and long-term work. Due to evolutionary reasons, it is difficult for even the TEP people themselves to adapt to such long-term work. Often work a day, you have to rest a day, otherwise it is easy to be over tired, resulting in short life. Archaeology has also proved this point. The TEP people in ancient times once stayed in the hunting age for a long time and stopped their progress. "

As soon as this conclusion was reached, there was a sound of discussion in the conference room.

This has never been thought of.

Zhang Yuan nodded and agreed: "in the earth civilization, there is a saying that there is a very important reason why there is no real farming culture on the African land. There are no large livestock that can be domesticated on the African grassland."

"In 1500 AD, the population of Africa was only 20 million, while the population of Xia, a large agricultural country, reached 160 million. This is the difference between hunting civilization and farming civilization."

Without farming culture, it is really difficult to produce a truly brilliant great civilization. Although human beings were born in African land, there is no real great civilization in this land. Even Egypt, once one of the four ancient civilizations, has long been assimilated by other religions and has not continued to the present.

Settlement enables mankind to store surplus food, and farming culture brings stable food reserves. These grains can feed soldiers, craftsmen and craftsmen. They are an important force in war and construction.

At the same time, with grain reserves, civilized countries can start giant projects such as the Great Wall.

It is with domesticated wild animals that human civilization can develop rapidly. Cattle and horses can not only cultivate land, but also a means of transportation.
