[Vegetation as a producer, when all vegetation is suppressed to grow, when all vegetation cannot grow taller, this also means that the large animals of the upper predators cannot appear. 】

[A battle for sunshine, but it unexpectedly solved the potential extinction crisis of the Muba people. 】

[Time is passing, round after round of vegetation growth and death, the carbon in the air is constantly absorbed by vegetation and then stored in the body, buried in the soil, the carbon content of the Martian atmosphere is decreasing, and the oxygen content is rising. 】

[The Muba people who have their footsteps all over the planet, bathed in more sunlight, pheromones float in the air, and under the stimulation of a large number of pheromones, the Muba people have also started a new evolution, which is the evolution of thinking instinct, this is the birth of wisdom......]

As 10,000,000 years passed, the second 10,000,000 years passed, and the shepherds grew taller and taller, approaching two meters in height, their torsos thickened, and cavities began to form in the center of the canopy, and a neuron-like structure began to grow in them.

Their two upper limbs began to evolve into muscle-like tissues, and this change also made the upper limbs more flexible and stronger, and began to gradually transition from two fingers to three fingers.

Their photosynthetic capacity is also stronger, the spectral frequency bands they can absorb are also expanding, and the leaves are gradually evolving to darker, eventually evolving into black, and the sunlight on them is absorbed almost without much reflection.

They don't just grow and reproduce, but occasionally they move stronger roots and wander around at a faster pace than they did more than 20 million years ago, as if patrolling their territory.

Whether it is Lu Yi or the rest of the Mars exploration plan, it can be clearly seen that the Muba people have evolved their initial wisdom at this time.

"Terrifying photosynthetic life, I understand why Commander Lu said that the disaster caused by the evolution of photosynthetic life intelligence will be more terrifying than ours."

Seeing this, looking at the shepherds on the screen who had evolved wisdom under the stimulation of population pheromones, Professor Su seemed to have guessed what was about to happen next, and his expression was full of complexity.

[When later generations investigated here and determined what happened at this time of the year, we had pride and pity in our hearts, proud of our shepherds, and pity for other species on Mars. 】

[We have no right to evaluate anything, after all, we are the descendants of the victors, we can only sigh that the survival of the fittest is the law engraved in the universe and in nature.

When you are not as strong as the other party, when you lose to the other in evolution, then you will face elimination, species competition, tribal disputes, and civilization competition. 】

[Due to the reproduction of the Muba people and the reproduction of vegetation, the carbon-containing gas in the air is gradually thinning.

The data we examined showed that when the Muba people walked out of the North Pole, the Martian atmosphere contained between 40 and 50 percent of the total carbon dioxide, carbon monoxide, and some sulfide gases.

The Muba people walked out of the North Pole for 70 million years, and the Muba people initially dominated the life species on the planet for 26 million years, due to the massive reproduction and death of vegetation, because large animals were unable to be born in evolution, the planet's carbon cycle began to collapse, and the carbon content of the air fell to less than 0.01 percent, while the oxygen content soared to 54 percent.

[This oxygen content is a feast for insects, amphibians, small vertebrates, etc., which have evolved, and if the vegetation and ferns of the planet are tall and lush at this time, they will definitely evolve large animals, and stabilize the balance of the planet's carbon cycle with the consumption of predators. 】

[But it's a pity that nature has no ifs, from the moment when the shepherd was dissatisfied with the sunlight being blocked by volcanic ash and rushed to the primeval forest with his upper limbs, Mars was destined to not be able to appear taller than the shepherds.

Without the large vegetation, the animals that evolved to the large would starve to death, and the large animals were doomed to not appear, and without the large animals, no one could threaten the Muba people at that time. 】

[The carbon cycle has collapsed......]

[A large amount of carbon-containing gas is absorbed and solidified by vegetation, and then buried underground as the vegetation dies, and the carbon returned to the atmosphere by natural decomposition and occasional forest fires alone is simply not enough for the vegetation and the shepherds of the entire planet, and the air carbon content falls below 0.005 percent.] 】

[The Muba people are photosynthetic life, and only 3 things are needed to maintain the life activities of the Muba people, water, carbon gas, and sunlight. 】

[The Muba people have waged a war, just like the previous battle for the sun, they have waged an extermination war against all the vegetation on the planet! 】

[They have evolved their initial intelligence, and they know that these vegetation are absorbing carbon gases from the air just like themselves, and by killing them, they can obtain more carbon. 】

[This is a war that has nothing to do with good and evil, only about survival, only about the advantages and disadvantages of evolution, the winner continues to reproduce and inherit, and the extinction of the loser species becomes history. 】

[The pheromones of the Muba people spread mightily in the air, and this war of extermination spread rapidly to the world like a pot of fire! 】

[One by one, the shepherds use their evolved more flexible upper limbs to uproot the superficial vegetation, so that they are completely exposed to the sun to death, and when they encounter trees with more developed roots, they will slowly strangle them with thicker movable roots!] 】

[The other vegetation could not resist the extermination war waged by the Muba, and the insects, amphibians, and small vertebrates did not understand what was happening......]

Patches of vegetation were killed by the shepherds, patches of animals died due to lack of food, and across the screen, Lu Yi and they seemed to be able to smell the rancid smell that covered the entire Mars and was emitted by the decay of animals.

"It's so kind, we humans are really kind!"

Professor Hill looked at the picture playing on the screen, and couldn't help but open his mouth wide and said with a shocked expression.

Everyone thinks that vegetation is the producer and the foundation of the environment, and the amount of vegetation represents the advantages and disadvantages of the environment, but they do not realize how terrible the disaster will be once the vegetation with photosynthesis as the energy source evolves wisdom.

Predators have evolved into intelligent races, because predators need to rely on the environment ecosystem to survive, so they will cause the extinction of a small number of species at most in their evolution and reproduction development, and even after the development of civilization, they will maintain the environment and maintain the diversity of species.

But once producers evolved into intelligent life, they didn't need to depend on ecosystems to survive, and they could slaughter all non-native species at will.

Although the Muba people are not plants, but the life before the differentiation of plants and animals, their position in the environment with photosynthesis as their energy source is no different from that of vegetation, and they all belong to the same producers.

When they completed the domination of the planet and gave birth to intelligence, the evolutionary history of human beings, the destruction of the environment and species by the terrifying Homo erectus, is not even a fraction of the world's slaughter of the shepherds.

Compared with the Muba people, human beings are kind to the bone.
