Ye Fei thought of this and couldn't help but think that the contradiction between scientific and technological races and cosmic creatures was innate. If humans had not been lucky enough to encounter mechanical civilization, they would have died in the crazy counterattack of the external bones.

Now recall that when the Deep Space Plan was just implemented, warships that were advancing separately would always encounter some cosmic creatures, but the thin scale star domain began to count, the thin scale tribe, the wood tribe, the disc tribe and the Atlantis people, a series of technological civilizations, a range of hundreds of light years, never encountered any cosmic creatures again!

Are there no cosmic creatures in these places? Of course it is impossible!

The only reasonable explanation is that these technological races have killed all the cosmic creatures they hate in front of their homes.

Cosmic creatures respect physical fitness and do not dominate their intelligence, but their intelligence can at least reach a certain level, and they can distinguish what is safe and what is dangerous. This is probably one of the important reasons why cosmic creatures cannot be found within the sphere of influence of scientific and technological civilization.

However, Ye Fei himself feels that there is no essential conflict between cosmic creatures and technological civilization.

The emergence and development of scientific and technological civilization requires strict conditions. The most important basis is that the planets must have enough heavy elements. Even if a planet with insufficient heavy elements appears, it will not be able to develop into the industrial age.

However, cosmic creatures or biological civilizations are not the case. Any habitable planet can provide them with a living environment, and there is no need to compete with scientific and technological races for a rare number of heavy element galaxies. If a cosmic creature has never been exposed to heavy elements, maybe lead, silver, gold or any kind of heavy element will be fatal and extremely poisonous to them.

Having said that, the most direct consequence of the lack of heavy element galaxies is that it limits the emergence and development of scientific and technological civilizations. Moreover, not all heavy element galaxies can evolve into scientific and technological civilizations. In addition, the emergence of smart creatures has certain chances, so the number of scientific and technological civilizations in the universe is naturally far inferior to the number of cosmic creatures or biological civilizations.

It is a pity that technological civilizations still have to compete for resources, suppress and annex each other and even massacre them, further limiting the number of technological civilizations.

Thinking of this, Ye Fei suddenly asked: "Dr. Feng, if there were no humans on Earth, would a cosmic creature evolve?"

Feng Lei looked at Ye Fei in surprise, thought for a while before answering: "I am astronomy and I understand a little bit of biology, but I don't go into it. From my understanding, the appearance of smart creatures is full of chance, but the impact of harsh environment on organisms is common. If humans do not appear, then in more than 4 billion years, the sun will become a red giant. The earth's environment changes drastically, and all living things will inevitably evolve to adapt to the environment more. However, it is hard to say whether there will be any kind of creature that evolves the ability to fly away from the earth before the sun swallows the earth."

"It is easy to evolve wings, but it is difficult to evolve into a spacecraft." The black bear said with a shaking head.

Feng Lei glanced at the seemingly lusty black bear and said, "This sentence makes sense. The conditions for the evolution of cosmic organisms are not as easy as we think, and the evolution speed of organisms is limited... No, in this way, the number of cosmic organisms should not be so many!"

He just finished saying this, and shook his head quickly and denied himself, "It's not like that. I'm wrong. Evolution into a cosmic creature is only the first step. Even cosmic creatures cannot live forever. They also need to breed offspring and expand their populations. After the population expands to a certain level, they will break up and then embark on different paths of evolution... Just like all spinal creatures originated from the Cambrian fish!"

Ye Fei and others were stunned. When they thought that their furthest ancestor was actually associated with fish, they felt that something was wrong with each other.

Although everyone has some understanding of the evolutionary history of organisms, few people know when the Cambrian period was, and they don’t know which type of spinal creature was. If Feng Lei had not mentioned it inadvertently, everyone would not have thought about this.

After all, humans and fish have too many differences in shape and cannot be classified as the same organism at all. At most, they can only be said to be the same biological system.

"Forget it, let's not talk about this." Ye Fei felt goose bumps on his back.

For some reason, he suddenly remembered the external bones. Those guys with bones growing outside are not a biological system with humans at all, and the body of bone-blocked meat is obviously more suitable for survival in the universe.

In addition to the bones, most cosmic creatures do have thick shells, and a few cosmic creatures without shells must have very tough skin.

From this perspective, if humans fail to appear, then when the sun reaches the end of life and enters the red giant stage, the possibility of spinal organisms evolving into cosmic creatures is extremely low, while insects or other crustacean creatures are far more advantageous than spinal organisms.

Thinking about the technological civilizations I had encountered, Ye Fei suddenly had the idea of ​​exploring the truth, trying to figure out whether these technological civilizations are all vertebral organisms similar to humans.

Next time you go back to the base star, you must ask the veterinarian for a clear question.

The Zangyuan continued to advance, and its roundabout flight method increased the time for the warship to approach the winning bid several times. After more than 30 light years of deep into the supernova ruins, the intensity of rays in interstellar space began to gradually increase, but it was far from reaching the level of threatening the safety of the warships.

Through the change curve of radiation intensity, Feng Lei and others calculated the radiation intensity near the pulsar, which theoretically did not exceed the warship's ability to withstand. However, Feng Lei felt that it was safer to be careful, so he suggested that Ye Fei continue to detour.

Ye Fei once again adopted Feng Lei’s suggestion, after all, he has specialized in his profession.

After passing by several galaxies, Zengyuan encountered another herd family. Ye Fei did not want to disturb them at first, but Feng Lei felt that the possibility of the test ship being separated from the super-light speed in interstellar space was very small, so he suggested that Ye Fei and the feudal family inquired if they had seen the test ship.

He felt that he could meet more herds on the road ahead.

Zhongyuan again dispatched the holographic satellite that was unfavorable. Unfortunately, there was no news. Instead, the holographic image made the herd family unclear, so it also thought that the holographic image was a lonely tribe member and strongly invited him to join his family.

Ye Fei was too lazy to waste his words and explain the origin of these herds, so he simply turned off the holographic image and directed the seed source to turn around.r1152
