In the petri dish, ten minutes passed, which was converted into the time of the petri dish, about 30,000 years passed, and his life span was reduced by another twenty minutes.

Under such a terrifying flow of time, earth-shattering changes have taken place in the petri dish.

Under the observation of the microscope, Yang Shou clearly saw that after 30,000 years, a strange species suddenly gave birth to in the garbage soil.

Because it is taken from the soil of the earth, the soil originally contained the genes and cells of the earth's species, but after 3,000 years, these cells used up the organic matter in the soil, and suddenly faced a shortage of food.

The energy of all things is conserved, and without food, they will starve to death, and a new round of natural selection has begun.

Most of the cells were starved to death, and a small number of cells chose to sleep, sealing their cell walls and membranes, waiting for the day when the environment would recover.

But even if it is sleeping, it still consumes energy, even if it is very low.

After 10,000 years, nine out of ten of the walls of the sleeping cells begin to dry up and crack and die.

But the miracle of life still happened, and the instinct to survive caused these cells to begin to reinvent themselves and evolve.

They abandon the structure of the cell wall and choose to transform the cell wall into an organ that specializes in absorbing small molecules free from the air.

Yang Shou did not close the petri dishes, they relied on this function to survive in an environment without food.

Another 10,000 years have passed, and the entire petri dish is full of this new type of cell.

They multiply rapidly, but even if the air circulates outside the petri dish, the free matter of the air is not enough to support the uncontrolled reproduction of the cells.

The development of cells fell into a bottleneck period of 10,000 years, and when Yang Shou picked up the microscope to observe, exactly 30,000 years had passed.

In the 30,000th year, in order to obtain more food and strengthen the race, this group of cells actually tried to evolve legs, wanted to move their positions, and actively searched for food.

Maybe the obsession with getting food is too strong, and they have evolved sixteen legs!

"Centipedes? These can't be the cells of centipedes on Earth, right?"

Yang Shou frowned, and every cell grew fluffy calves, squirming wildly, from the garbage soil, part to the land, part to the ocean.

With the help of the microscope, Yang Shou saw that the cells in the accelerated state were moving rapidly, and the death of generations of cells allowed them to divide into two parts and settle on the land and the sea.

"The ocean is the cradle of life, and the cells on land have chosen the wrong path. ”

Yang Shou's focus is also on the observation of the ocean, those cells who have left their homes and left the garbage heap have encountered another extinction in the ocean.

Even if they don't have the concept of breathing and don't drown, most of them die because they absorb too much water and swell.

A new extinction of species began, and less than 10% of the cells survived, continuing a new round of adaptation and evolution.

In the sea, food is abundant, and in the 40,000th year, the cells of the ocean multiply wildly, filling the entire ocean.

And the terrestrial cell, because it has found new food, has also become the overlord of the terrestrial.

The fluff on the legs of the marine cells is green, so the whole ocean becomes the color of forgiveness.

In order to adapt to the environment of the ocean, the constitution of the marine cells has become softer, and the defense power has decreased, but correspondingly, the absorption and utilization efficiency of food has become much higher.

Land cells, on the contrary, have increased their defenses and evolved a hard case to cope with the complex terrain environment on land.

In the 300,000th year of petri dish evolution, ocean cells have finally ushered in a great change.

A small number of cells fused by chance, and the leg hairs of dozens of ocean cells fused with each other, intertwining them tightly.

After countless fusions and deaths, a new type of creature finally evolved, the leg worm.

Because of the fusion of sixteen legs, the survival of the fittest creatures has only one leg, and the fluff is chimerated, forming a new creature with legs all over its body.

"A new type of cell is born. ”

Yang Shou was a little surprised that this "ancient creature" was born under his own witness.

If the previous sixteen-legged cells still have the shadows and genes of the earth's creatures, the current leg-to-legged insects, after 300,000 years of evolution, have become independent "alien species" ----- petri dish species.

After 300,000 years of evolution, it is not an exaggeration to say that they are extraterrestrial species, and they are very different from terrestrial species in terms of internal and external structure.

"With the production of compound organisms, what is the next direction for their development?"

Ocean cells have legs that can eat and walk, but they are still facing a food crisis, and if they want to evolve again, they must get more food.

There was not enough food in the air or in the ocean to support them, so the core of these leg worm cells began to switch, abandoning the animal-like way of eating, mimicking plants and starting to produce chloroplast-like substances for photosynthesis, imitating plants to obtain nutrients from sunlight.

Gradually, the whole ocean is filled with a green plant that can swim around the ocean to forage for food and photosynthesize by twisting its body, Cordyceps legislature.

"Now that we are able to be self-sufficient in oxygen, it's time to completely isolate the petri dish from the earth's air from entering. ”

Yang Shou completely sealed the petri dish, artificially created a world different from the earth's environment, and continued to observe their development.

If they don't, the civilization of the earth will have too much influence on them.

What he wants is a different kind of species evolution, so that it is possible to evolve a civilized path that can cure his cancer.

Moreover, he has been using the Time Acceleration ability, which will reduce his lifespan to half of what it used to be, which means that he will have to find a way to solve the cancer problem in a month and a half.

Taking a deep breath, Yang Shou continued to observe, and two hours passed, that is, the 360,000th year of the petri dish world.

Unable to satisfy the ocean, Cordyceps legislature, which has dominated the sea, tries to invade the land and starts a battle for survival with another group of compatriots more than 300,000 years ago.

Cordyceps can't break the tortoise shell of the land cell, and the land cell also has sixteen legs, which move very fast.

The hard carapace was responsible for the defense, and the sixteen legs were responsible for the attack, and in an instant, the leg cordyceps began to rout.

But as time passed, with the crazy number of developments, the leg cordyceps made up for the quality gap with quantity, and the terrestrial cells were brutally grinded to death.

There is no way, terrestrial cells reproduce too slowly because of food, while Cordyceps legis relies on photosynthesis and can reproduce indefinitely, and the difference in the number of the two sides is too big.

At this point, the petri dish has entered the era of Cordyceps leg, and Cordyceps has become the protagonist of this era, a well-deserved overlord, and has a tendency to spread towards the glass wall around the petri dish, trying to climb out of the petri dish.

Is this still worth it?

Yang Shou silently took a basin of boiling water, made a small opening in the petri dish, and flooded the entire petri dish.

The era of Cordyceps leg, end.

"History says: Divine Grass Age, the leg cordyceps is boundless, spreading the whole world, and even found an invisible ladder leading to the divine realm, in a vain attempt to ascend to the sky, the gods were furious, raining down boundless boiling water, and the world was destroyed because of it. ”

Yang Shou took out his notebook and recorded this short-lived era.

Really, this race is too inflated, has legs, occupies the land, and still wants to go to the sky?

Let you run out, and the hell knows if it will cause any butterfly effect on the earth's environment.

Absolutely not allowed!

Yang Shou silently observed, waiting for the next evolution of the species.

380,000 years before history, with the extinction of Cordyceps leg, the next species was born, a legged, invertebrate reptile was born in countless legs Cordyceps and boiling water, they were born resistant to high temperatures, with six legs, fused with the hard shell of ancient cells on land, and began the mighty road of exploring the world.

"Animals, animals have finally appeared!"

The appearance of animals requires enough food and other survival bases, and the endless corpses of Cordyceps legged are their best breeding ground.

"You really have to thank the leg cordyceps. ”

Yang Shou took a deep breath and named the four-legged hard-shelled creature the plate worm.

Invertebral means that there is no emotion and no consciousness, and there is still a long way to go from intelligent beings.

But Yang Shou is already very satisfied, watching the evolution of species, extinction, in just two hours, more than 300,000 years of evolution, compared to a short hundred years of people, he has witnessed too much splendor.

"I'm going to be able to find a way to stay alive for a long time. ”

He still has a little 900 million years to go!

Petri dishes, because of the legacy of Cordyceps legislature, began to enter the era of biological explosions.

All kinds of organisms have begun to diversify their evolution, and aquatic terrestrial plants, inheriting the photosynthesis of Cordyceps legislas, are spread throughout the petri dish continent.

All kinds of invertebrate creatures are born in all corners of the petri dish, and in every breath of Yang Shou, there are creatures born and die.

"No, the petri dish is too small to accommodate the Big Bang. ”

Yang Shou discovered the key problem, it is still in the early stage, the largest creature in the petri dish is only the size of a small thumb, but as time goes by, sooner or later, a creature the size of a dinosaur on the earth will appear.

Are they born in their own petri dish that is forty centimeters in length, width and height?

It's scary to think about!

But Yang Shou didn't think of a way to solve this problem for a while, and could only witness the creatures continuing to explode and evolve, and a variety of small ants, grasses, and trees grabbed territory in the petri dish.

In the 450,000th year of prehistory, countless species were born in the petri dish, and from the outside, the petri dish was crawling with ants.

Finally, these species found the end of the world, and there was no way to expand in all directions, and they found an invisible ladder to try to ascend to the sky.

"Huh. ”

Yang Shoumo smiled emotionally, brought another basin of boiling water, and flooded the petri dish.

The second species extinction in prehistory was again because these species tried to ascend to the sky and provoke the majesty of the cultivators.

"After the second mass extinction, the Big Bang, all species were not satisfied with the status quo, and then climbed the ladder of heaven, causing the great flood of destruction and the destruction of the world again. ”

Another hour passed, and the petri dish ushered in 480,000 years of prehistory.

On the basis of the diversity of the previous batch of species, the evolution of species has been much faster, and for the first time the birth of vertebrates, fish, has been ushered in.

"It's not far from sapient beings, but their size must be limited, otherwise the consequences will be unpredictable. ”

How to limit their size? Yang Shou had a rough idea in his heart.

Organisms adapt to environmental mutation and evolution, self-modify their genetic state, and adapt to the environment.

Then if he waits for ten minutes, that is, 30,000 years, when they are too big to hold in the petri dish, he will pour boiling water into the petri dish and destroy the world.

So will they evolve genes on their own, control their body size, to prevent the petri dish from running out of space, instinctively climbing the ladder, and then extinct?

After two extinctions, Yang Shou has actually discovered that the species born in the 480,000th year are much smaller than before.

"If they can write size into their genes, that's the perfect solution to this problem!"
