With Doctor Octopus Meng Yang and Xiao Budian, the changes in the biosphere in the 23 bases can be monitored at any time, and organized into various charts to find the laws hidden under the massive data.

When the various data of the biosphere are counted, some patterns emerge, and although the biosphere of each site is different, the commonalities between them can be observed through the data.

For a biosphere, there is an environmental volume for the survival elements of various organisms, and the amount of environment around a certain biological element fluctuates at any time relative to a single organism.

One oxygen distance, the amount of oxygen in a base may be 3 cubic kilometers, and the oxygen content is 22%, for a certain gazelle, the oxygen content fluctuates between 20-25% depending on its position.

The proportion of oxygen tolerance of gazelles fluctuates between 11% and 40%, high or low, and if it lasts too long, it will cause damage to the gazelle's body.

The elements needed for biohygiene are not only oxygen, for the gazelle it also needs sunlight, it needs temperature, it needs water, it needs salt, it needs calcium, it needs trace elements, it needs food, it needs space to run, it needs a suitable mate.

The volume of the environment is different for each of them, and any one of them must be guaranteed to change within the tolerance of any one organism at all times.

And the change of each of these items will have a linkage effect, forming a chain reaction between the various creatures. If a biosphere is to be robust enough and resistant to disturbances and fluctuations, it must ensure that the volume of all these elements fluctuates in a reasonable range.

This is a complex chain reaction network, if it is described as cause and effect, it is a complex causal network, the same cause can cause N effects to change, and these effects will become the cause of other events. Constant transmission, even looping, vicious chain reaction, and so on.

Meng Yang was a little dizzy when he saw the massive data, and he simply dropped these charts.

"Doctor Octopus, you know about homeostasis, right?"

"Know! It is a state that can resist disturbance and automatically reset, and the autostable state is the lowest energy level. ”

“ok！ For example, if the photosynthesis of plants is designed to be self-stable, the resistance of oxygen content to fluctuations can be greatly improved. ”

"Sorry, boss, please explain in detail."

"It's very simple, design a special gene in the plant, when the oxygen content is higher than the normal value, the excess chloroplast will be turned off, and the biochemical processes in the plant will consume more oxygen from the outside world; However, if the oxygen content is lower than normal, more chloroplasts are activated, more carbon dioxide is absorbed, and the biochemical process consumes the oxygen produced by itself. ”

"In this way, the fluctuation of oxygen content can be designed as a simple homeostasis, which can be automatically reset by the adjustment of the plant."

"By analogy, we can design many environmental elements to be similar to homeostasis, so that they always automatically return to their ideal values."

"Boss, I see what you're thinking."

"Can we use this idea to transform the ecosystem?"

"Yes, in fact, the life of the earth itself has this function. Take people as an example, when there is a lack of food, a woman will automatically reduce the chance of pregnancy, and when the food is abundant, the woman will increase the chance of pregnancy, which is the autonomous regulation of the human body, and there should be a concept similar to what you said about homeostasis. ”

"If organisms themselves have functions similar to self-regulation, why do biosphere collapses so often?"

"Maybe it's a design flaw, maybe it's because the speed of biological self-regulation can't keep up with the speed of change in environmental factors."

Slow self-regulation...... The environment changes at a rapid rate......

Yes, a herd of deer is stocked on a desert island, and the deer herd has no natural predators to breed freely, and the only factor that restricts the number of deer is the area of pasture on the desert island.

It stands to reason that the deer herd should always be kept in the right number, but in practice it is not, and the deer population fluctuates periodically between flooding and widespread starvation.

This illustrates a very critical problem, the autonomic regulation function of organisms has to respond slowly, there is a long lag period, and the existence of this lag period leads to the continuous emergence of huge interference waves in the ecosystem, which is actually the biggest enemy of the ecosystem.

Thinking of this, an inspiration flashed in Meng Yang's mind.

"Doctor Octopus, if we think of the autonomous regulation of organisms to environmental changes as a kind of biological pointer, then if we adjust the biological pointer and increase its sensitivity, won't we be able to reduce the amplitude of disordered fluctuations and increase the level of homeostasis?"

"Boss, if we follow your train of thought, I'm afraid we will need to change the genes of most of the creatures in the biosphere."

"Why?"

"Different organisms adapt to different ecosystems, different environments. The biological indicators of the organisms bred by the large ecosystem of the earth correspond to the large-scale environment of the earth. The sensitivity of their biological pointers is appropriate and moderate in the context of the earth, but when they are placed in a simulated ecosystem that is only a dozen cubic kilometers in size, their biological pointers are seriously inadequate. ”

"All the organisms selected from our 23 ecosystems are taken from the earth's environment, so their biological pointers are too sluggish, and we may need to adjust them all."

"One organism corresponds to one ecosphere......"

"Yes, I believe that if given enough time and intergenerational reproduction, organisms will adjust themselves to their environment."

"In that case...... So let's adjust the biological pointers of all the creatures in our ecosystem, and then design the homeostatic structure. I believe that after the adjustment, the stability of the ecosystem will be improved a lot. ”

"Yes, boss!"

Ending the conversation, Meng Yang's thoughts couldn't help but diverge, since it is said that each creature will adjust itself to adapt to the changes in the surrounding environment and the ecosystem in which it is located.

So looking at the entire cosmic scale, suppose a civilization goes out of its home planet and begins to colonize the universe, when it colonizes planet after planet.

What is certain is that there will be various differences in the gravity, rotation, sunlight, mineral content, air content, magnetic field, radiation and other aspects of these planets, and it is almost impossible for a planet that is completely identical to the parent star.

The bodies of the inhabitants of the colonized planet will automatically adapt to the new environment, and there is no difference between one generation and two generations, but after ten generations and hundreds of generations, perhaps after thousands of years, the inhabitants of the colonized planet will become very different from the inhabitants of the home planet.

Originally, they belonged to the same people, but because of the different environments, they slowly became two peoples, and even over time, they would become two species, and reproductive isolation appeared between them, and at this time, the colonization was a complete failure.

Perhaps after thousands of years of development, this colonized planet has become unrecognizable not only in terms of human race, but also in terms of culture, and the two planets that were originally one may become two completely different intelligent species.

In the case of Earth, for example, people may admit that Caucasians, yellow people, Indians, and Inuit are all humans, but will people recognize apes as their own kind? Will chimpanzees be admitted as their own kind?

The essence of living things is to adapt to changes in the environment, and it is difficult to define them as living things without this ability, so environmental changes are rigid and irreversible, and for a long enough time, the difference in the environment is probably the biggest black hand to eliminate interstellar civilizations.
