Thinking of this, Ye Fei couldn't help but think that the contradiction between the technological race and the cosmic creatures was simply innate, and if the human race hadn't been lucky enough to encounter the mechanical civilization, I am afraid that it would have died in the crazy counterattack of the Outer Bone Man.

Now recall that when the Deep Space Program was just beginning to be implemented, the warships that went separately would always encounter some cosmic creatures, but since the Scales began to be counted, the Scales, Wood, Saucers and Atlanteans, a series of technological civilizations, hundreds of light-years away, have never encountered any kind of cosmic creatures!

Aren't there cosmic creatures in these places? Of course not!

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

Cosmic creatures respect their physique and do not dominate their intelligence, but their intelligence can at least reach a certain level above a certain level, and they can distinguish what is safe and what is dangerous, which 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 felt that there was no essential conflict between cosmic creatures and technological civilization.

The emergence and development of scientific and technological civilization requires strict conditions, and the most important foundation is that the planet must have enough heavy elements, and even if there is an intelligent race on the planet with insufficient heavy elements, it will not be able to develop into the industrial age.

This is not the case with cosmic creatures, or biological civilizations, where any habitable planet can provide them with a living environment, and there is no need to compete with technological races for a scarce number of heavy elemental galaxies. If you are a cosmic creature who has never been in contact with heavy elements, you may be able to use lead, silver, gold, or any other heavy element. They are deadly poisons.

Having said that, the most direct consequence of the lack of heavy element galaxies is that it restricts the generation and development of scientific and technological civilizations, and not all heavy element galaxies can evolve scientific and technological civilizations, and the emergence of intelligent beings has a certain degree of chance, and the number of scientific and technological civilizations in the universe is naturally far less than the number of cosmic creatures or biological civilizations.

It is a pity that scientific and technological civilizations still compete for resources, suppress each other, swallow and even slaughter, and further limit the number of scientific and technological civilizations.

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

Feng Lei glanced at Ye Fei in surprise. He thought very formally for a moment before replying, "I study astronomy." I know a little bit about biology, but I don't go deep. From what I know, the emergence of intelligent beings is full of accidents, but the impact of the harsh environment on living beings is common. Suppose humans don't show up. Then more than four billion years later. The sun has become a red giant, the environment of the earth has changed drastically, and all living things will inevitably evolve to adapt to the environment. However, it is difficult to say whether any of the creatures will evolve the ability to fly away from the earth before the sun engulfs the earth. ”

"It's easy to evolve wings, but it's hard to evolve into a spaceship." The black bear shook his head and said.

Feng Lei glanced at the seemingly rough black bear and said: "This sentence makes sense, the conditions for the evolution of creatures in the universe are not as easy to appear as we think, and the evolution speed of creatures is limited...... No, according to that, there shouldn't be so many creatures in the universe! ”

As soon as he finished saying this, he quickly shook his head and denied himself: "No, I think it's wrong, there's nothing wrong, evolving into cosmic creatures is only the first step, even cosmic creatures can't live forever, they also need to breed offspring to expand the population, and after the population expands to a certain extent, they will 100% break up, and then embark on a different evolutionary path...... Just like all vertebrates originated from the Cambrian fish! ”

Ye Fei and the others were stunned for a moment, and when they thought that their farthest ancestor was actually associated with fish, they felt that something was wrong with their mixed bodies.

Although everyone has some understanding of the evolutionary history of organisms, few people know exactly when the Cambrian period was, let alone what kind of earliest vertebrate organisms were.

After all, humans and fish are too different in morphology to 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 goosebumps bulge on his back.

I don't know why, he suddenly remembered the outer bone people, those guys whose bones grow outside are not the same biological system as humans at all, and the physique of flesh and bone is obviously more suitable for survival in the universe.

Except for the outer skeleton people, most cosmic creatures do also have heavy shells, and the few cosmic creatures without shells must have very tough skin.

From this point of view, if humans do not appear, then when the sun reaches the end of its life and enters the red giant stage, the possibility of vertebrates evolving into cosmic creatures is extremely low, and insects or some other crustacean creatures have far more advantages than vertebrates.

Thinking about the scientific and technological civilizations he had encountered, Ye Fei suddenly had the idea of finding out, wanting to find out whether these scientific and technological civilizations were all vertebrates similar to human beings.

The next time you go back to the base star, be sure to ask the veterinarian about it.

The Seed Source continued to move forward, and the circuitous flight mode lengthened the time for the battleship to approach winning the bid several times, and after going deep into the supernova ruins for more than thirty light years, the intensity of the rays in interstellar space began to gradually increase, but it was far from reaching the Cheng Dù that threatened the safety of the battleship.

Through the curve of the change in radiation intensity, Feng Lei and others calculated the radiation intensity near the pulsar, which theoretically did not exceed the bearing capacity of the battleship, but Feng Lei felt that it was safer to be careful, so Jian Yì Ye Fei continued to detour.

Ye Fei once again adopted the construction of Feng Lei, after all, there is a specialization in the art industry.

After passing by a few galaxies, the Seed Source ran into a herdsman family again, Ye Fei didn't want to disturb them, but Feng Lei felt that it was very unlikely that the expedition ship would break away from the superluminal speed in interstellar space, so Jian Yì Ye Fei and the herdsmen asked if they had seen the expedition ship.

He felt that on the road ahead, he should be able to meet more herdsmen.

The provenance once again dispatched the invincible holographic satellite, but unfortunately there was still no news, but the hologram made the herdsman family unclear, and the hologram was a lonely clansman, and strongly invited him to join his family.

Ye Fei was too lazy to waste his tongue to explain the origin to these herdsmen, so he simply turned off the hologram and commanded the provenance number to turn around and leave. (To be continued......)
