"The plankton in the sea appeared... the mother nest, and began to set a genetic lock to limit the size of the spores!"
Xu Zhi frowned and gave the order silently.
Orchards are just that big, it's impossible to let them evolve too big.
In the memory of the previous empress, it also showed that the way of evolution of the huge body was wrong.
There is no need to deliberately expand the size of the Zerg. Maintaining the small size of the original insect is the correct evolutionary method. The smaller the size, the easier it is to produce a qualitative change in energy.
They no longer expand in size.
Since then, the size of the normal species in the sand table is a bit smaller than that of ordinary ants. This is the real bug, Zerg. And the largest species, even if it evolves to the level of a dinosaur, is no bigger than a cat.
A worm, the size of a cat, is already an exaggeration.
And a sand table of 100 mu is equivalent to the size of a small province for a tiny ecological creature of the size of a small ant.
On the afternoon of the sixth day, after experiencing the single-celled Paleozoic ocean in the first five days, it finally changed drastically, and multicellular organisms began to appear in the seawater.
In a few minutes, Xu Zhi felt like an accelerated ecological discipline film. On the artificial ocean of this pond, new plankton species were born and died in seconds, giving birth to the next generation...
Soon, in the pond in the orchard, patches of various strange aquatic plants floated.
Xu Zhi originally wanted to give it a try, throwing a single cell to evolve species in the ocean, but he didn't expect it to be so fierce.
"Ten thousand years hastened into one day, and it took only six days. After 60,000 years of species evolution, the single-celled organisms in the ocean evolved into plankton in the sea, forming a formation similar to the end of the "Phanerozoic" on the earth. In the ultra-Paleozoic ocean where the Cambrian explosion happened billions of years ago, this Zerg spore was so powerful that it exploded... …”
Xu Zhi didn't understand the evolution history of the earth.
But he can naturally go back to the room, turn on the laptop, search the Internet, frantically fill up on the evolutionary era of the earth, the birth and origin of species, the Cambrian, Silurian, Devonian...
After all, the earth can be used as a reference.
"But it's getting dark soon, and my biggest worry has started. The world of the sand table will be destroyed..."
He looked at the man-made ocean in the yard, and looked up at the dark sky, the last twilight of dusk on the corner of the wall.
The evolution of cell division is accelerated ten thousand times, and he condenses and accelerates ten thousand years into one day, which is equivalent to five thousand years of day and five thousand years of night.
It was getting dark now, which meant that the five thousand years of day had passed, and five thousand years of endless night was about to usher in.
Sunshine is the source of all things. These newly born aquatic plants in the ocean will lose photosynthesis and die directly.
Sure enough, just after nightfall, the moment the sun lost its light, there was a drastic change in the sea water.
A large piece of aquatic plants withered, sank to the bottom of the sea, and lost their lives, like the Dead Sea, lifeless under the night.
"In my evolutionary era, the first mass extinction has begun...not as fast as I thought."
Xu Zhi took a deep breath.
He checked the information on the Internet.
In the long evolution of the epoch, the earth has experienced five tragic mass extinctions from the birth of single cells, the evolution of multi-cells, and the reproduction of various Paleozoic species!
In history, the most famous nature is the mass extinction at the end of the Cretaceous period. Sixty-five million years ago, the overlord of the earth, the destruction of the age of dinosaurs, killed 80% of the animals at that time.
The Earth's first mass extinction was actually more than 400 million years ago, at the end of the Ordovician period.
That's because the temperature plummeted and the sea level dropped, which led to the destruction of the earth's marine ecosystem and directly extinct 85% of marine species at that time.
Now, different from the Earth Era, the sand table under his hand is due to the arrival of night, and the endless night that lasted five thousand years suddenly fell, and the sun suddenly disappeared, causing his first mass extinction of species.
The earth is a huge planet, among which hundreds of billions of species will survive the survival of the fittest and have huge compatibility, even if there is a mass extinction, they can survive.
But his place is different, the environment is too small.
Logically speaking, even if the ponds and oceans are filled, there are only tens of millions of races. According to Darwin's theory of evolution, the extremely small biological base is not enough to evolve a new creature that adapts to the environment.
"But this is a highly adaptable Zerg single-cell-spore, which can survive on 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, the moonlight poured down from the yard, and half an hour passed in the lifeless ocean full of plant corpses, and suddenly another faint blue surface surfaced.
It was an ant-sized blue plant with delicately shaped leaves.
Losing direct sunlight from the sun, this plant chose to direct the source of photosynthesis to the moon, where the light is extremely thin, and survived.
After the plant successfully survived the first round of mass extinctions, it grew, developed, and died in just a few seconds, like a sped-up movie video.
It began to evolve rapidly from generation to generation, competed with natural selection, and crazily adapted to the dark night environment. Water chestnuts and discs appeared, like lotus leaves, laid flat on the sea surface, in order to absorb the moonlight from the sky in the courtyard more widely.
Another hour passed.
As the only marine species in the sand table, the aquatic plant named "Blue Moon Grass" by Xu Zhi has undergone tens of thousands of generations of species evolution and has begun to form various branches.
There are angular ones, elongated ones, oval ones, deep-sea ones, shallow-sea ones... At this time, it even developed two differentiated species.
Part of the blue moon grass continues to absorb moonlight during evolution, enhancing the conversion efficiency of moonlight.
Some of the blue moon grasses actually started to turn to carnivore, preying on other blue moon grasses. They also absorbed the moonlight, so they glowed faintly, attracting other blue moon grasses to float over and devour them.
Seeing this, Xu Zhi admired the tenacity and wonder of life, and the survival of the fittest said, "After the first mass extinction of life, the only living aquatic plant has developed its own diverse civilization in the ocean of darkness. .”
He found a black notebook, picked up a pen, and recorded the evolution of the sand table,
"How about recording the countless epochs of my sand table evolution according to the epochal calendar of the earth
In the Cambrian period on the earth, there was a biological explosion, and it was the era of origin of all life on earth. There were dinosaurs, humans, and various beasts... However, the biological explosion here in my place is facing five thousand years of darkness. ... Let's call it An Wu Ji. "
He was very excited, and in this black notebook, he turned over the first page of Genesis, and wrote the first line on it:
[Dark Warrior period, the sky and the earth changed suddenly, the sun set and the moon rose, the world fell into a long darkness that lasted for five thousand years, 99% of marine life became extinct, and only the blue moon grass survived by absorbing the moonlight, becoming the only surviving species. The dark ocean is extremely prosperous, and the blue moon grass has become the overlord of this era]
He looked at the pond named Ocean of Life, silently expecting,
"According to the biological evolution history of the earth, the ocean is the origin of all life. Marine plants first appeared, and then continued to reproduce, which are marine animals, Zerg cells, what kind of marine animals will evolve... .."
He stayed up all night and waited until dawn.
The seventh day, finally started!
However, animals did not evolve on the seventh day as Xu Zhi thought, but ushered in another terrifying mass extinction!
because the sun rises.
With the moment of sunrise, all kinds of blue moon grasses in the sea that flourished in the middle of the night quickly withered.
Originally at night, they received the weak moonlight, but now they suddenly received such strong direct sunlight, as if they were burned, and sank into the bottom of the sea one after another.
In an instant, the blue moon grass began to become extinct on a large scale again.
"The second mass extinction broke out so quickly, and I just survived for a short time. It's simply horrific..."
This is the death of life.
In the long evolutionary era of species, in units of hundreds of millions of years, countless species were born and extinct, which is the epic of the vast planet.
The evolution of life from the spores was long and rotten, but now in just a few hours, countless prosperity and ups and downs were displayed in front of Xu Zhi's eyes. The shock to Xu Zhi was powerful and inexplicable.
By the afternoon, a tinge of blue is slowly coming to life from the dead vegetation.
It was a blue moon grass in the shape of five stars. It also ushered in its own mutation evolution, successfully escaped this mass extinction, transformed in the scorching sun, and was reborn from the ashes.
In order to better adapt to the strong sunlight environment, it began to reproduce from generation to generation.
In just a few minutes, it died, reborn, and multiplied for countless generations. It gradually changed from blue to dark, and gradually became purple-black... Finally, a mysterious black-blue five-pointed star seaweed was formed.
It has beautiful and mysterious balanced leaves with five-pointed stars, which can be stretched and opened.
At night, the five corners are opened, flat on the sea surface, and the area that absorbs moonlight is enlarged. During the day, in order to prevent strong sunlight, it shrinks by more than half and becomes a flower bud.
A bit of a mimosa pattern.
The mass extinction of species is death, and it is also an opportunity for weak species to rise.
In the entire ocean, there is no longer any species competing with it for the living environment, and it began to multiply rapidly again, multiplying various offshoots, and filling the entire ocean vigorously.
"Survive five thousand years of scorching sun and five thousand years of dark night."
"The sun and the moon are in the sky for five thousand years. As the only living being of countless species, you have experienced the scorching sun and darkness. You are a real hero. Let's call it Purple Zhaocao." The second page of the diary.
Continue to record the second mass extinction event in the evolution history of his biological era:
[In the Guangwu period, the world changed suddenly, the moon set and the sun rose, and the scorching sun that lasted for five thousand years appeared in the sky. The overlord of the blue moon grass that had survived the dark warrior period began to extinction on a large scale. Among them, the purple of the weak line of blue moon grass Zhaocao, unexpectedly rose from the sky, and became the protagonist of the era that dominated this era]
