"The scenery here is nice!"

Yu Ting looked at the dark blue sea in front of her, and then looked at the dark green mountains behind, she was used to seeing the dark universe, and it really gave people a feeling of the earth.

"And the beach, it's so comfortable. Situ Na trotted on the beach, the soft and delicate sand on her feet not to mention how comfortable, even the beaches on the earth are difficult to have such comfortable sea sand, the key is that the endless coastline is all such sand, and there is no human pollution, even if some of the coast is floating with rotten wood, it is also with the breath of nature, unlike the current coast on the earth, full of man-made garbage.

Clean!

Pure!

In addition to the ecosystem here, this planet with an environment and climate that is more than 98% similar to the Earth is simply an unexplored and perfect planet.

"The sea water here is super clean!" Lin Yuxin also ran, jumping there against the sea, the cold sea water slapped on her feet, and the whole person was extremely excited.

"Even the composition of the sea water is similar to that of the earth, and this is simply a second earth. Nami sighed.

"You two don't go too far. Zhao Shuhan shouted.

"Got it~~~" shouted in his mouth that he knew, and both of them had already run to the far sea.

"You see, the oversized animals are !! in the sea"

Situ Na and Lin Yuxin shouted excitedly on the sea.

A group of huge sea creatures, not knowing whether they were playing or migrating, happened to pass by the sea directly in front of them, jumping up and down, and setting off huge waves on the sea.

"The view is really nice. Lin Xueyan said with a smile.

"I didn't expect that there is such a planet at the edge of the universe, it's really rare. Li Yunyao took a deep breath of pure air, even the composition of the air was almost the same, and the more adequate oxygen content made the air here feel more spiritual.

"In fact, planets similar to Earth are very common in the entire universe, and even this galaxy may be able to find tens of thousands or even more of them. Leah admired the beautiful scenery in front of her and smiled faintly, "But seriously, even life forms can be so similar, it's really very rare, like Nami said, it's really a bit like another earth." ”

"Shouldn't the evolved life of a similar planet and a similar ecological environment be similar?" Shen Bingqing wondered.

"That's not necessarily, planets can be infinitely similar, but life forms are not directly related to the environment, just like the vast majority of life on the earth depends on oxygen to survive, in fact, oxygen is a prison that life on earth can never get rid of. Shirley said.

"What do you mean?" Wu Hao was stunned.

"Oxygen oxidation is not only the substance, but also oxidizes life, if the life on the earth does not rely on oxygen, maybe the life span will be enhanced a lot, just like the life that evolved in some anaerobic ecosystems in this universe, the average life span assigned to them by fate has reached tens of thousands of years, and the average life span of life on earth organisms is only a few decades, the change and alternation of each generation greatly limits the development speed of human civilization, human beings have to spend a lot of time and energy to raise the next generation, and the time really used for civilization construction is actually very little。 ”

Sydney said that she was also a little puzzled: "There are not many lives in the universe that need oxygen to survive, and there are even fewer civilizations based on oxygen, although there are some, but most of them are ultra-low-level civilizations, from this point of view, the development of the earth is quite good, in fact, I have always been a little strange, life on the earth did not need oxygen to survive in the early days, why did this transformation start inexplicably later." ”

"Hmm, the more you talk about it, the more I don't understand. Wu Hao was confused.

"Out of the human vision, looking at all the civilizations in the entire universe, oxygen is not a good thing, and it can even be said to be a shackle of civilization, several cosmic regenerations have proved this, but it is difficult for all life that relies on oxygen to develop a truly powerful civilization system, even if it develops a civilization, it is difficult to mature and strong, and it is impossible to know exactly what is the direct relationship between oxygen and lifespan, but the life span of organisms that rely on oxygen is not too long throughout the universe, and this directly leads to the inability of civilization to develop. ”

Shirley said: " The early ecological structure of the earth is more important than the polar gravity, according to the biological model to continue to evolve, the later life on the earth should evolve an anaerobic life system, throughout the universe, all high-level civilizations are established by anaerobic life, if the earth has been evolving according to this route, the earth should also be a cradle of advanced civilization, and the conditions of the earth are very good, very conducive to the growth of civilization, but it is very strange that when the early life of the earth was forming, a large number of cyanobacteria appeared inexplicably, produced a large amount of oxygen, and directly poisoned all early life, all life that evolved in the later stage naturally relied on oxygen to survive, and the entire life cycle was limited to death, and it could not be achieved at all. ”

"I remember that in the past, it was said in biology books that it seemed that the appearance of cyanobacteria created the basis of life for life on the whole earth, how did it suddenly become poison?" Zheng Jiaxuan couldn't cry or laugh, and the three views were completely destroyed.

"The knowledge structure of any civilization is established within the scope of its own limited cognition, and human cognition of life depends on oxygen to exist, and it is natural to think that the emergence of oxygen creates space for life, just like the knowledge structure of those anaerobic life civilizations, they are very fortunate that they did not encounter such a devastating substance as oxygen in the early stage of life development, otherwise their civilization would no longer exist, a truth. Shirley laughed.

"Why do you suddenly feel that the future of mankind is not good?" Wu Hao said with a wry smile.

"If human beings want to develop into a super civilization, they need to pay far more than those anaerobic life civilizations, human beings have gone through thousands of years and hundreds of generations of life to enter the space age, and they may only need one generation of efforts to do it, and the pace of human progress in this universe is very difficult. Leah sighed.

"So did I do something wrong?" Wu Hao suddenly said, thinking about the problem according to this logic, shortening human life is equivalent to reducing the development speed of human civilization to a certain extent.

"In reality, it doesn't seem to be. Shen Bingqing thought for a while and said: "Husband, although you have reduced the average life expectancy of human beings, time trading has released a lot of human energy, which has also accelerated the pace of progress of human civilization, and we can clearly feel the changes when we are on the earth." ”
