Homo sapiens

Li Qingye, who had been inspecting Southeast Asia for more than a month through a synchronous robot, now came to Latin America.

But his body is still in Pangu Realm.

Bagheira appears in his small ecological circle.

"Mr. Chairman, the Space Division has issued a Class A document, which contains an investigation report on life on Venus."

Li Qingye rolled his eyes, took the tablet, and said, "Is it about those nitrogen algae?"

"No, it's a new discovery." Bagheira shook his head.

At this time, Li Qingye had already seen the investigation report on the tablet. He raised his eyebrows: "Underground creatures? Or such advanced forms of creatures? Interesting..."

He continued to look through it carefully.

The creature tentatively named "Venus Pangolin", and a series of subsequent explorations and sample captures carried out by the Yungong Base, they discovered a total of 387 new species in this formation.

Most of them are microorganisms. There are only 14 species of relatively large multicellular organisms such as Venusian pangolins.

Their ecosystem relies on Venus' abundant geothermal energy. Without such abundant geothermal energy and the ability of the atmosphere to retain heat, they would not be able to obtain enough energy.

The explosion of life on the earth originated from the geothermal heat of the black chimneys on the seabed and the irradiation of the sun.

As for the birth of underground life on Venus, according to research conducted by the Yun Palace Base and related ecological and biological researchers, it is most likely caused by underground hot springs.

Although there is no sunlight, the heat energy on the surface of Venus is very abundant. Although the underground temperature is not high due to the obstruction of the stratum, it is precisely this relatively low temperature that makes life possible.

After all, the high temperature of 400 to 500 degrees Celsius on the surface of Venus cannot be tolerated by ordinary metals, let alone living things.

In the area 1,000 to 1,500 meters underground, the temperature is maintained between 33 and 46 degrees Celsius, a temperature that many organisms can withstand.

In the investigation report, investigators also discovered that Venusian pangolins feed crystal ants. Crystal ants feed on sulfur-based fungi. Sulfur-based fungi rely on geothermal heat, animal carcasses, and excrement to reproduce. This forms a relative line. Complete food chain.

Venusian pangolins dig caves where the humidity and temperature are more suitable, and then stock some crystal ants and sulfur-based fungi in these caves.

Of course, these caves are not just random, but areas of rock formations rich in minerals.

Venus pangolins are semi-social creatures, usually living in family units, while crystal ants are colonial creatures, with at least tens of thousands in a nest.

Due to the extremely high pressure on Venus, these creatures have evolved bodies that can adapt to the ultra-high pressure.

Li Qingye was more curious about how these creatures breathed.

Investigators were equally curious.

Judging from the samples obtained, bacteria and fungi are all developed from anaerobic bacteria. Oxygen is poisonous gas for them. They absorb sulfur dioxide, carbon dioxide and water, and use heat energy to generate thermal synthesis to achieve energy conversion.

Although sulfur-based fungi release oxygen, the oxygen they release is quickly absorbed by the elemental iron, elemental copper and other elemental active metals in the underground tunnels.

Obviously, the carbon dioxide and oxygen conversion efficiency of sulfur-based fungi is average and not as terrible as the cyanobacteria family, which greatly slows down the oxidation rate of the Venusian strata.

Similarly, crystal ants and Venusian pangolins do not breathe oxygen, but methane gas.

Throughout the underground world, there are a large number of anaerobic bacteria, many of which are methane-producing bacteria, which causes the methane concentration in the formation to reach about 17%.

The underground atmosphere of this ecosystem contains about 72% carbon dioxide, about 17% methane, 5% sulfur dioxide, and 3% nitrogen dioxide. The remaining 3% is hydrogen sulfide, oxygen, radon, hydrogen, nitrogen, and Ammonia and the like.

Li Qingye discovered that the methane-producing bacteria on Venus can convert organic matter into methane much more efficiently than here on Earth, even more powerful than the methane-producing bacteria he originally modified using genetic recombination technology.

Of course, he also saw some problems, that is, the environments of both parties were different.

The underground ecosystem of Venus has always been dominated by anaerobic bacteria. Coupled with high temperature and pressure all year round, this environment makes it easier for methane bacteria to decompose organic matter and convert it into methane.

The earth's environment certainly cannot give anaerobic bacteria much living space. The earth is the home of oxygen-loving organisms.

Li Qingye sighed: "Nature is really magical. Completely different species are produced in just one drink and one peck."

Although the Yun Palace Base's research on Venus's underground ecosystem has only just begun at this stage, he seems to have already predicted the future.

Homo sapiens companies will surely discover similar ecosystems on other planets.

This kind of underground ecosystem may be more common than surface ecosystems like the earth.

After all, if the environmental conditions of the Earth are used as the standard, the so-called habitable zone of the planetary system will be very narrow, and even the main sequence stars of the planetary system will have relatively strict restrictions.

But if the underground ecosystem of Venus is used as a standard, then almost all terrestrial planets and large rocky satellites have the potential to give birth to life.

From the perspective of the birth of life, the core elements for the birth of life are temperature, energy, and suitable chemical media.

The earth is a planet with a suitable temperature, a large amount of water resources, and a strong geomagnetic field. In fact, the conditions are relatively harsh.

However, the stratigraphic structure of terrestrial planets raises another possibility, which is groundwater, geothermal, and stratigraphic protection. These three conditions can be met in many terrestrial planets.

Therefore, Li Qingye can probably predict that in the Milky Way and in various planetary systems, the probability of underground civilization being born is higher than that of surface civilization.

After all, if you look at the current solar system, you will know that there are underground organisms on Venus, Mars, and the Moon, and on top of that there are organisms in the atmosphere of Venus.

The ratio of life on the surface, underground, and atmosphere is: 1:3:1.

There are other large rocky satellites in the solar system that have not been explored, such as Titan.

From this point of view, the number of planets with underground organisms may be several times, or even dozens of times, that of planets with surface organisms.

Of course, it is more difficult for underground organisms to develop to the height of human civilization than that of human civilization.

Because it can be understood that underground organisms are protected by a thick rock layer, and this rock layer is like the earth's atmosphere and magnetic field.

Underground civilization needs to break through the limitations of the rock layer and become surface civilization before it can enter the universe.

They have to cross one more layer than human civilization before they can become a first-level civilization that controls the planetary system.

Breaking through the limitations of the rock layer is itself a very dangerous thing. It is like entering outer space. The surface environment is definitely not suitable for underground organisms to live for a long time.

Therefore, underground organisms, surface organisms, and atmospheric organisms should have their own pros and cons, depending on development and luck.

Human civilization can develop to this stage, and luck accounts for a large part.

After all, in the history of the evolution of life on earth, there are many mass extinctions of organisms that destroy the world. Human beings just happened to take advantage of this relatively safe vacuum period to rise rapidly.

If humans and dinosaurs were of the same era, there is a high probability that they would also receive lunch boxes with the dinosaurs.

Every civilization in the universe is a miracle.
