Chapter 892 The Gravity of Reality

Evolutionary pressure, or selection pressure, can be thought of as external pressure exerted on a biological evolutionary process, thereby changing the direction in which the process is going.The so-called "natural selection, survival of the fittest" means that nature exerts selection pressure on organisms, so that those who adapt to the natural environment can survive and reproduce.

Selection pressure is one of the driving forces of evolution.

Yawgmoth grinned: "This question is not that difficult. Evolutionary pressure, apart from 'climate and environment change', is more from other species, or other individuals within the population. A species, other Natural enemies, their prey, other species in the same ecological niche, and every individual competing for courtship within the population are all sources of evolutionary pressure. A lot of evolution comes from 'competition between species'."

"In addition, there is also a serious path dependence in evolution. For example, once entering a parasitic ecological niche, it basically binds its own fate to the fate of the host species, and it is almost impossible to leave. But once the environment of the planet changes drastically, Then the most prosperous population will be hit hard—for example, by a meteorite. At this time, the surviving species that take other routes and have the potential to evolve will start to diversify and occupy the vacated ecological niche.”

"I even think that in the last 30 years, the human ancestors who have been 'large predators' have more evolutionary pressure from within the species!"

Ingrid nodded: "It makes sense."

Only Xiang Shan sighed: "It's too unromantic."

Xiang Shan sincerely hopes that there will be a civilization that is so obsessed with the starry sky.

At least with such a civilization, the universe will not be too lonely.

After this chitchat, Ingrid and David each submitted their routine reports.Of course, these two people are very loyal, and I especially thank Yawgmoth and Xiang Shan for their contributions in this brainstorming.

In addition, the park also began to methodically analyze the machines inside Ogun.However, it seems that the bureaucrats of some members of the Security Council have disputes over certain issues. Therefore, the Rama project has not yet been authorized to dismantle the alien machinery, and everyone has to study the most fragmented wreckage first.

The first to produce results, of course, are those who study the symbols on the alien slates.As Xiang Shan said, alien computers also use binary.There is indeed an area composed of 0 and 1, which corresponds the symbols to the mechanical instructions one by one.

Xiang Shan is not alone in making this point.But at the end of the research report, the project leader, an old scholar from the European Union, still included Xiang Shan's name in the list of "cooperating researchers".

Scholars on the earth believe that this symbol system is not a symbol system that is convenient for operators to operate electronic devices like the "mnemonic" in the assembly language of the earth, but is specially designed to compress information and increase the information density of the slate. means.

Normal mnemonics will directly select some existing words or their abbreviations with one and only one natural semantic meaning from natural language to replace mechanical language such as "010001110111011100101".In this way, it is convenient for the biological brain to memorize, and it is also convenient for the user to operate the machine.The high-level language is even better, closer to natural language.

Of course, even if humans can convert those symbols into a mechanical language written purely in 0 and 1, it is useless.

Indeed, those are "languages ​​that machines can understand", but there are differences from machine to machine.It's not that if you put these things into the computer on the earth, it will run naturally.It's not realistic.

The information inside cannot be converted into human-readable content.The content here may also include "video and audio files with unknown formats", but unknown formats are unknown formats.Computers developed by people on earth may not be able to open some file formats used by people on earth, let alone aliens.

In addition, many people believe that this symbol system is likely to be specially designed to increase the information density of the slate.It's really not like normal natural language.There are a large number of symbols in it, which are combinations and variations of simple geometric figures.This is not in line with normal writing habits.

However, a group of scholars such as Shen Yuanzun also raised doubts.They consider it too hasty to base judgments on "writing habits".

"This is a very unreasonable judgment." Shen Yuan said, "Human writing habits are completely based on the physiological basis of human beings. But it is entirely possible that aliens have a completely different physiological basis from human beings."

In the Rama Project Park, everyone is happily discussing everything about aliens every day, as if it is a science fiction literature research society.

But most of the time, scientists are also dreaming.

After all, there is no evidence.

Xiang Shan felt that this kind of life was quite comfortable.

One day after dinner, Lao Liu called Xiang Shan to stop, saying that Xiang Shan would go for a walk with him to digest food.

On a certain path, Xiang Shan asked, "Mr. Liu, do you have something to tell me?"

Lao Liu nodded: "Indeed. Xiao Xiang, I have to ask you a question. What do you think of the Rama project?"

"It's pretty good, isn't it?" Xiang Shan said without hesitation: "The work is not heavy, and it's fun to discuss about aliens every day."

Old Liu patted his forehead: "Yes."

"What's the matter? Teacher, why do you want to talk about this issue?"

Xiang Shan faintly felt something was wrong.

Old Liu said: "As you know, in our country, when we assembled our research team, the time was very short. We only found a lot of 'possibly useful majors' here, and the team is very bloated. Then Now it has become like this...the main thing is that there is nothing in it, and there are too few research objects."

Xiang Shan was keenly aware of it: "You want to go back?"

Lao Liu looked at the huge white tent in the distance: "When I was young, I also liked watching "Flying Saucer Quest", but this is the earth. How do you say it?" Any thoughts that transcend flying They'll all come crashing down, the gravity of reality is too heavy'."

"But, this is the study of aliens!"

"The technology of aliens is only a little more advanced than ours." Lao Liu said: "And we have five big countries here, and there are many scholars from other countries. Even some of the wreckage has to be sent to China for exchange." Conduct research for research institutes with military backgrounds in China. This 'point' may not be enough for so many people. The competition is too fierce."

"Even if you can get something from it, I'm afraid it will be subject to many restrictions because of the confidentiality regulations."

　Note that according to the setting, Lao Liu is born in the 80s, and it is normal for him to know that sentence.
