"The plankton in the sea have appeared … Mother nest, start setting the gene lock to limit the size of the spore!"
Xu Zhi frowned and silently gave the order.
The orchard was only so big, and it was impossible to let them evolve too big.
In the memory of the previous queen, it also showed that the evolution method of the huge body was wrong.
There was no need to deliberately expand the size of the Zerg. Maintaining the original small size of the insects was the correct way of evolution. The smaller the body, the easier it was to produce energy qualitative changes.
Their body size no longer expanded.
Since then, the size of the normal species in the sand table was smaller than an ordinary ant. This was the real insects, the Zerg. And the largest species, even if they evolved to the level of dinosaurs, would not be bigger than a cat.
A bug the size of a cat was already a very exaggerated thing.
And the sand table of 100 acres was equivalent to the size of a small province for the microscopic ecological creatures the size of small ants.
On the afternoon of the sixth day, after experiencing the previous five days of single-cell Paleozoic ocean, there was finally a drastic change, and multicellular creatures began to appear in the sea.
In a few minutes, Xu Zhi was like an accelerated ecological discipline film. On the artificial ocean of this pond, new plankton species were born and died in a few seconds, giving birth to the next generation …
Soon, in the pond in the orchard, there were all kinds of strange aquatic plants floating.
Xu Zhi originally wanted to give it a try and throw single-cell species in the ocean to evolve, but he didn't expect it to be so fierce.
"Ten thousand years accelerated to one day. It's only six days, 60,000 years of species evolution. The single-cell organisms in the ocean have evolved into plankton in the sea, forming a super-Paleozoic ocean similar to the end of the Phanerozoic Eon, the Cambrian biological explosion 500 million years ago. This Zerg spore is really powerful …"
Xu Zhi didn't understand the evolution history of the earth.
But he could naturally go back to his room, turn on his laptop, search the Internet, and cram for the evolution history of the earth, the origin of species, the Cambrian, the Silurian, the Devonian …
After all, the earth could be used as a reference.
"But it's going to be dark soon. My biggest worry has begun. The world of the sand table is going to be destroyed …"
He looked at the artificial ocean in the yard and looked up at the gloomy sky. The last afterglow of dusk fell on the corner of the wall.
The evolution of cell division was accelerated by ten thousand times. He condensed ten thousand years into one day, which was equivalent to five thousand years of day and five thousand years of night.
Now that the sky was dark, it meant that five thousand years of daylight had passed, and five thousand years of endless night was about to arrive.
Sunlight was the source of all living things. The newly born aquatic plants in the ocean would lose their ability to photosynthesize and would die directly.
Sure enough, as soon as night fell and the sunlight disappeared, the seawater underwent a drastic change.
Large amounts of aquatic plants withered and sank to the bottom of the sea, losing all life. It was like a dead sea. Under the night sky, there were no signs of life.
"In my evolutionary era, the first great extinction has begun … I didn't expect it to be so soon."
Xu Zhi took a deep breath.
He had done some research on the internet.
In the long evolution of eras, from the birth of single cells to the evolution of multi-cells, the reproduction of all kinds of ancient species, Earth had experienced five tragic mass extinctions!
In history, the most famous event was naturally the mass extinction at the end of the Cretaceous period. Sixty-five million years ago, the Earth was once the hegemon of the world, the destruction of the dinosaur era. At that time, 80% of the animals died.
And the first mass extinction on Earth was actually more than four hundred million years ago, at the end of the Ordovician period.
That was because the temperature plummeted and the sea level dropped, which led to the destruction of Earth's marine ecosystem, directly wiping out 85% of the marine species at that time.
Now, different from the era of Earth, the sand table under his hand was because of the arrival of night. Suddenly, five thousand years of endless night fell, and the sun suddenly disappeared, causing the first mass extinction that belonged to him.
Earth was a huge planet with billions of species. After the survival of the fittest, it had great compatibility and could even survive the mass extinction.
But it was different here. The environment was too small.
Logically speaking, even if the ponds and oceans were filled, there would only be tens of millions of species. According to Darwin's theory of evolution, an extremely small number of species was not enough to evolve a new species that could adapt to the environment.
"But this is a single cell of the Zerg with extremely strong adaptability — the spore. If it can survive in a barren planet, there is no reason why it can't …"
Xu Zhi took a deep breath, feeling a little excited and uneasy.
He waited quietly. Moonlight spilled from the yard, and the lifeless sea of plant corpses was filled with a full half an hour later. Suddenly, a faint blue color appeared on the surface.
It was a blue plant the size of an ant with delicate leaves.
After losing direct sunlight from the sun, this plant chose to aim its photosynthesis source at the moon, where the light was extremely weak, and was able to struggle at death's door.
This plant successfully survived the first round of mass extinction. In a short few seconds, it grew, developed, and died, just like a fast-forwarded movie.
It began to rapidly evolve generation after generation, a natural selection, and crazily adapted to the dark environment. Water caltrops and round plates appeared, like lotus leaves laid flat on the surface of the sea in order to absorb more moonlight from the yard's sky.
Another hour passed.
As the only marine species in the sand table, the aquatic plant that Xu Zhi named "Blue Moon Grass" had experienced tens of thousands of generations of evolution and began to form various branches.
Some were angular, some were slender, some were oval, some were deep sea, some were shallow sea … At this time, it even developed two different species.
A portion of the Blue Moon Grass continued to absorb moonlight during evolution, increasing the efficiency of moonlight conversion.
A portion of the Blue Moon Grass even began to eat meat, preying on other Blue Moon Grasses. They also absorbed moonlight and emitted a faint fluorescent light, attracting other Blue Moon Grasses to swim over and then devour them.
Seeing this, Xu Zhi praised the tenacity and wonder of life. "After surviving the first mass extinction, this only surviving aquatic plant actually developed its own diversified civilization in the dark sea."
He found a black notebook, picked up a pen, and recorded the evolution process of this sand table.
"How about I also record the countless eras that my sand table has evolved according to Earth's era calendar?
The Cambrian period on Earth had a biological explosion, which was the origin era of all life on Earth. That was why there were dinosaurs, humans, all kinds of fierce beasts … But the biological explosion here was faced with five thousand years of darkness … Let's call it the Dark Warrior period. "
He was excited. In this black notebook, he flipped to the first page of the founding era and wrote the first row of words:
[The Dark Warrior period, the world suddenly changed, the sun set and the moon rose. The world fell into five thousand years of long darkness. 99% of the marine life went extinct, leaving only the Blue Moon Grass to survive by absorbing moonlight. It became the only species that survived and flourished in this dark sea. The Blue Moon Grass became the overlord of this era.]
He looked at the pond called the Ocean of Life and silently looked forward to it.
"According to the history of biological evolution on Earth, the sea is the origin of all life. Marine plants first appeared, and then continued to reproduce, followed by marine animals. What kind of marine animals will the cells of the Zerg evolve into …"
He did not sleep all night and waited until dawn.
The seventh day finally began!
However, as Xu Zhi expected, animals did not begin to evolve on the seventh day. Instead, it ushered in another terrifying mass extinction!
Because the sun rose.
At the moment of sunrise, all kinds of Blue Moon Grass in the flourishing ocean rapidly withered.
Originally, they received weak moonlight at night. Now that they suddenly received such strong direct sunlight, they sank to the bottom of the sea as if they were burned.
In an instant, Blue Moon Grass began to go extinct on a large scale.
"The second mass extinction happened so soon. I just survived not long ago. It's so tragic …"
This was the death of life.
In the long evolutionary era of species, countless species were born and extinct in hundreds of millions of years. It was a vast planetary epic.
The process of evolution of spores was long and rotten. At this time, in just a few hours, countless prosperity and ups and downs were displayed in front of him. The shock it brought to Xu Zhi was powerful and inexplicable.
In the afternoon, a touch of blue gradually recovered from the dead plants.
It was a five-star shaped Blue Moon Grass. It also ushered in its own mutation and evolution, successfully escaping the mass extinction this time. It transformed in the scorching sun and was reborn from the fire.
In order to adapt to the strong sunlight environment, it began to reproduce generation after generation.
In just a few minutes, it died, was reborn, and reproduced for countless generations. It began to gradually turn from blue to dark purple … Finally, it formed a mysterious black-blue five-star seaweed.
It had a five-star beautiful and mysterious balanced leaf that could expand and contract.
At night, it opened its five corners and lay flat on the surface of the sea, increasing the surface area to absorb moonlight. During the day, to prevent strong sunlight, it shrank by more than half and turned into flower buds.
It was a little like a mimosa.
The mass extinction was death, but it was also an opportunity for the weak species to rise.
In the entire ocean, no species competed with it for survival. It began to reproduce rapidly, producing all kinds of branches, and the entire ocean was full of vitality.
"Survived five thousand years of scorching sun and five thousand years of night.
"Five thousand years of sun and moon in the sky. As the only survivor of countless species, you experienced the scorching sun and darkness. You are a true hero. Let's call you Purple Moon Grass." Xu Zhi smiled. He silently picked up the pen and turned to the second page of the black diary.
He continued to record the second mass extinction in the evolutionary history of the biological era that belonged to him.
[Light Martial Era, the world suddenly changed. The moon set and the sun rose. The sun hung in the sky for five thousand years. The overlord of Blue Moon Grass that had survived the Dark Martial Era began to go extinct on a large scale. Among them, Purple Moon Grass, a weak branch of Blue Moon Grass, rose in the sky and became the protagonist of that era.
