Evolutionary pressure, or selective pressure, can be thought of as external pressure exerted on a biological evolutionary process, thereby changing the direction of the process. The so-called "natural selection, survival of the fittest" means that nature imposes selective 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 problem is not that difficult. In addition to 'climate and environmental changes', evolutionary pressure comes more from other species, or other individuals within the same group. A species, its Natural enemies, their prey, other species in the same ecological niche, and every individual competing for mate rights within the population are all sources of evolutionary pressure. A lot of evolution comes from 'competition between species.'"

"In addition, evolution also has serious path dependence. For example, once you enter a parasitic ecological niche, your fate is basically bound to the fate of the host species, and you will almost never break away. But once the planet's environment changes drastically, Then the most prosperous population will suffer a heavy blow - such as a meteorite. At this time, surviving species with evolutionary potential that have taken other routes will begin to differentiate and occupy the vacated ecological niche."

"I even think that in the past 300,000 years, the evolutionary pressure of human ancestors who have become 'large predators' came more from within the species!"

Ingrid nodded: "That makes sense."

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

Xiangshan sincerely hopes that there will be a civilization that is so obsessed with the stars.

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

After this small talk, Ingrid and David submitted their routine reports respectively. Of course, these two people are very loyal, and they especially thank Yawgmoth and Xiangshan for their contribution in this brainstorming.

In addition, the park also began to analyze the machinery inside Ogun in an orderly manner. However, it seems that bureaucrats within some member states of the Security Council have disputes over certain issues. Therefore, the Rama project has not yet received authorization to dismantle the alien machinery, and everyone has to study the most fragmentary remains first.

Of course, the first to produce results were those who studied the symbols on the alien tablets. As Xiangshan said, alien computers also use binary. There is indeed an area composed of 0s and 1s, which corresponds to symbols and mechanical instructions one by one.

Xiangshan is not the only one to express this opinion. However, 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."

Earth scholars believe that this symbol system is not a symbol system like the "mnemonic" in Earth's assembly language that facilitates operators to operate electronic devices, but is specifically designed to compress information and increase the information density of the stone slabs. means.

A normal mnemonic will directly select some existing words or their abbreviations with one and only natural semantics from natural language to replace mechanical languages ​​​​such as "010001110111011100101". This makes it easier for the biological brain to remember, and also makes it easier for users to operate the machine. High-level languages ​​are even better and closer to natural languages.

Of course, even if humans could convert those symbols into mechanical language written purely in 0s and 1s, it would be of no use.

Indeed, those are "languages ​​that machines can understand", but there are differences between machines. It doesn't mean that if you put these things into the computer on Earth, it will run naturally. This is not realistic.

The information inside also cannot be converted into content that humans can read. The things inside may also include "video and audio files of 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 those from aliens.

In addition, many people believe that this symbol system was probably specially designed to increase the information density of the stone slabs. It really doesn't look 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 consistent with normal writing habits.

However, a group of scholars such as Kanbaru Zun also raised doubts. They believe that judging based on "writing habits" is too hasty.

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

In the Rama Project Park, everyone is happily discussing everything about aliens every day, as if it were some kind of science fiction literature research meeting.

But most of the time, scientists are just dreaming.

After all, there is no evidence.

Xiangshan felt that this kind of life was quite pleasant.

One day after dinner, Lao Liu stopped Xiangshan and asked Xiangshan to go for a walk with him to eat.

On a certain trail, Xiang Shan asked: "Teacher 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 isn't heavy, and it's quite fun to discuss aliens every day."

Old Liu patted his forehead: "Yes."

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

Xiangshan felt something was wrong.

Old Liu said: "As you know, our country was very short on time when it came to assembling our research team. We have just found a lot of 'professions that may be useful', and the team is very bloated. Then Now it has become like this...the main reason is that there is nothing in it and there are too few research subjects."

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

Old Liu looked at the giant white tent in the distance: "When I was young, I also liked watching "UFO", but this is the earth. What is the saying? 'Any transcendent and flying thoughts' They will all fall to the ground with a bang, the gravity of reality is too heavy."

"But this is research on aliens!"

"The technology of aliens is only slightly more advanced than ours." Old Liu said: "And here we have five major countries, as well as many scholars from other countries. Even some of the wreckage has to be sent to China for handover. Let’s conduct research for domestic research institutes with military background. I’m afraid this ‘a little bit’ is not enough for so many people. The competition is too fierce.”

"Even if you can profit from it, I'm afraid it will be subject to many restrictions due to confidentiality regulations."

Note that according to the setting, Lao Liu was born in the 1980s, and he knew that this sentence was a normal thing.
