Chapter 618

"The scenery here is good!"

Yu Ting looks at the dark blue sea in front of her and the dark green mountains behind her. She is used to the Dark Universe. It really gives people a sense of earth.

"And the beach. It's so comfortable." Stuart is trotting on the beach. The soft and delicate sand on her feet is not so comfortable. Even the beaches on the earth are hard to have such comfortable sand. The key is that the endless coastline is full of such sand, and there is no human pollution. Even some decaying wood floating on the coast is natural, It's not like the coast of the earth today. It's full of man-made rubbish.

Clean!

Pure Che!

In addition to the ecosystem here, this planet, whose environment and climate are more than 98% similar to the earth, is a perfect undeveloped planet.

"The sea water here is super clean!" Lin Yuxin also ran up and hopped in front of the sea water. The cold water patted on her feet, and the whole person was very excited.

"Even the composition of sea water is similar to that of the earth. This is the second earth." Nami sighed.

"It's too far for both of you." Cried Zhao Shuhan.

"I know ~ ~" he said, and both of them had already run to the sea.

"You see, super large animals are in the sea!"

Situ Na and Lin Yuxin cried out excitedly on the sea.

A group of huge sea creatures, not knowing whether they are playing or migrating, just pass by the sea in front of them, jump up and down, and set off huge waves on the sea.

"The scenery here is really good." Lin Xueyan said with a smile.

"I didn't expect such a planet to exist on the edge of the universe. It's really rare." Li Yunyao took a deep breath of pure air, and even the composition of the air was almost the same. The more abundant oxygen content made the air here feel more spiritual.

"In fact, planets like the earth are very common in the whole universe. Even this galaxy may be able to find tens of thousands or even more such planets." Liya appreciated the beautiful scenery and said with a faint smile, "but really, it's very rare that even life forms can be so similar. As Nami said, it's really a bit like another earth."

"Shouldn't similar planets, similar ecological environments, and evolved life be similar?" Shen Bingqing was puzzled.

"It's not necessarily that the planets can be infinitely similar, but the life form has no direct relationship with the environment, just like the vast majority of organisms on the earth rely on oxygen for survival. In fact, oxygen is the prison that the earth's organisms can never get rid of." Said Shirley.

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

"Oxygen oxidizes not only matter, but also living organisms. If the living organisms on the earth do not rely on oxygen, their lifespan may increase a lot, just like the life evolved from some anaerobic ecosystems in the universe. The average lifespan assigned to them by fate is up to tens of thousands of years, while the average lifespan of the living organisms on the earth is only a few decades, The alternation 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 nurture the next generation. In fact, there is very little time for the construction of civilization. "

Sydney said with some doubts: "there are not many lives in the universe that need oxygen to survive, and there are few civilizations that depend on oxygen. Although there are some, most of them are ultra-low level civilizations. From this point of view, the development of the earth is pretty good. In fact, I've always been a little strange that life on the earth doesn't need oxygen to survive in the initial stage, Why did you start this kind of transformation later

"Well? The more you say it, the more I don't understand. " Wu Hao was confused.

"From the perspective of human beings, looking at all the civilizations in the whole universe, oxygen is not a good thing, or even a shackle of civilization. Several times of regeneration of the universe have proved this point. It is very difficult for any life relying on oxygen to develop a truly powerful civilization system, and even if it develops a civilization, it is difficult for it to become mature and powerful, It is impossible to know exactly what is the direct relationship between oxygen and life span, but the life span of living organisms relying on oxygen is not too long throughout the universe, which directly leads to the failure of civilization to develop. "

Shirley said: "the proportion of oxygen in the early ecological structure of the earth is polar. If we continue to evolve according to that biological model, the later life of the earth should evolve into an anaerobic life system. Throughout the universe, all high-level civilizations are built up by anaerobic life. If the Earth continues to evolve along this line, The earth should also be a cradle of advanced civilization, and the earth's conditions are very good, which is very conducive to the growth of civilization. However, it is strange that when the earth's early life was forming, a large number of cyanobacteria appeared inexplicably, producing a lot of oxygen, directly poisoning all the early life, and all the life evolved in the later stage naturally depended on oxygen to survive, The whole life cycle will be limited and will not go at all. "

"I remember that it used to be said in biology books that the emergence of cyanobacteria created the basis of life for the whole earth. How did it suddenly become a poison?" Zheng Jiaxuan couldn't laugh or cry, and Sanguan was completely destroyed.

"The knowledge structure of any civilization is established within its own limited cognitive scope. In human cognition, life all depends on oxygen. Naturally, the appearance of oxygen creates space for life. Just like in the knowledge structure of anaerobic life civilization, they are very glad that there was no such destructive material as oxygen in the early stage of life development, Otherwise, their civilization will no longer exist, for one reason. " Shirley said with a smile.

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

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

"So did I do something wrong?" Wu Hao suddenly said that to think according to this logic, shortening human life is equivalent to reducing the speed of human civilization development to some extent.

"Actually, it doesn't seem so." Shen Bingqing thought for a while and said, "husband, although you have reduced the average life span of human beings, time trading has released a lot of human energy, which has also accelerated the pace of progress of human civilization. We can obviously feel the change when we are on the earth."
