Shepherding Humanity (Nurturing Humanity)

"Plankton in the sea appeared. The mother's nest began to set a genetic lock to limit the size of the spore creatures!"

Xu Zhi frowned and gave orders silently.

Orchards are just that big, it's impossible to let them evolve too big.

The memory of the previous generation of the mother emperor also showed that the evolution of the huge body was wrong.

There is no need to deliberately expand the size of the Zerg. Keeping the original small size of the insect is the correct way of evolution. 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 smaller than that of ordinary ants. This is the real bug, the Zerg. And the largest species, even if it evolves to the level of dinosaurs, will not be bigger than a cat.

A worm, the size of a cat, is already an exaggeration.

And a 100-acre sand table is equivalent to a small province for micro-ecological creatures in the size of a small ant.

On the afternoon of the sixth day, after the unicellular Paleozoic ocean for the first five days, it finally changed dramatically, and multicellular organisms began to appear in the seawater.

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 seconds, giving birth to the next generation.

Soon, in the pond in the orchard, patches of various exotic aquatic plants floated.

Xu Zhi originally wanted to give it a try and cast a single cell to evolve species in the ocean, but he didn't expect it to be so fierce.

"10,000 years accelerated to one day, this is only six days, the evolution of species that lasted 60,000 years, the single-celled organisms in the ocean, evolved into plankton in the ocean, forming a similar to the end of the Earth's 'Phanerozoic', five In the super-Paleozoic ocean where the Cambrian biological explosion occurred hundreds of millions of years ago, this Zerg spore is so powerful that it explodes."

Xu Zhi didn't understand the evolutionary history of the earth.

But he can naturally go back to his room, open his laptop, search the Internet, and frantically make up for the evolutionary history of the earth, the birth and origin of species, the Cambrian, Silurian, and Devonian periods.

After all, the earth can be used as a reference.

"But as soon as it gets dark, my biggest fear begins, and the world of the sandbox will be destroyed."

He looked at the artificial ocean in the yard, and looked up at the gloomy sky, the last rays of dusk on the corner of the wall.

The evolution of cell division is accelerated ten thousand times. He condensed and accelerated ten thousand years into one day, which is equivalent to five thousand years of daytime and five thousand years of night.

Now that it is dark, it is equivalent to the five thousand years of day that have passed, and the endless night of five thousand years is about to usher in.

Sunlight is the source of all things. These aquatic plants that have just been born in the ocean will lose their photosynthesis and die directly.

Sure enough, just as night fell, the moment the sunlight was lost, there was a drastic change in the sea water.

Large swaths of aquatic plants withered, sank to the bottom of the sea, and lost their lives, like the Dead Sea. Under the night, there was no life.

"In my evolutionary era, the first mass extinction of organisms started not as fast as I thought."

Xu Zhi took a deep breath.

He checked the information online.

In the long period of evolution, the earth has experienced five tragic mass extinctions from the birth of a single cell, the evolution of multiple cells, and the reproduction of various Paleozoic species!

In history, the most famous natural is the mass extinction at the end of the Cretaceous period. Sixty-five million years ago, the once overlord of the earth, the destruction of the age of dinosaurs, killed 80% of the animals at that time.

The first mass extinction of the earth was actually more than 400 million years ago, the mass extinction 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, which directly wiped out 85% of the marine species at that time.

Now, different from the Earth Era, the sand table under his hands was due to the arrival of night, and suddenly an endless night of five thousand years fell, and the sun suddenly disappeared, causing the first mass extinction that belonged to him.

The earth is a huge planet, in which billions of species are eliminated, and there is a huge compatibility, even if the mass extinction of living things can survive.

And he is different here, 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, a very small biological base is not enough to evolve a new creature that adapts to the environment.

"But this is an extremely 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 shone down from the yard, and the dead sea was full of plant corpses. After half an hour, a faint blue suddenly surfaced.

It was an ant-sized blue plant with delicately shaped leaves.

Losing direct sunlight from the sun, the plant chose to target the source of photosynthesis at the extremely low-light moon, and was able to survive.

After successfully surviving the first round of mass extinction, the plant grew, developed, and died in just a few seconds, like an accelerated movie video.

It began to evolve rapidly from generation to generation, competing with natural selection, wildly adapting to the dark night environment, and appeared water chestnuts, discs, like lotus leaves flat on the sea, in order to absorb the moonlight from the sky in the yard in a wider range.

Another hour passed.

As the only marine species in the sand table, the aquatic plant named "Blue Moon Grass" by Xu Zhi has experienced tens of thousands of generations of species evolution and began to form various branches.

There are angular, slender, oval, deep-sea, and shallow-sea types. At this time, it even developed two differentiated species.

Some blue moon grasses continue to absorb moonlight during evolution, enhancing the conversion efficiency of moonlight.

Some of the blue moon grasses actually started to turn to carnivorous and prey on other blue moon grasses. They also absorbed the moonlight, and with this faint fluorescence, they attracted other blue moon grasses to float over, and then swallowed them.

Seeing this, Xu Zhi admired the tenacity and wonder of life, the survival of the best, "After the first mass extinction of life, this only surviving aquatic plant actually developed its own diverse civilization in the dark ocean. ."

He found a black notebook, picked up a pen, and recorded the evolution of this sand table.

"Or, according to the epoch calendar of the earth, record the countless epochs of the evolution of my sand table?

In the Cambrian period on the earth, there was a biological explosion, which is the origin of all life on earth. Only dinosaurs, humans, and all kinds of beasts can be found. The biological explosion here in my place, but facing the darkness of 5,000 years, is called the Anwu period. Bar. "

With great interest, he turned over the first page of the founding century on this black notebook, and wrote the first line of words on it:

[Dark Martial Period, the sky and the earth changed suddenly, the sunset and the moon rose, the world fell into a long darkness of 5,000 years, 99% of marine life went 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 called the ocean of life, silently expecting,

"According to the history of biological evolution of the earth, all life originates in the ocean. Marine plants appear first, and then continue to multiply, that is, marine animals, Zerg cells, what marine animals will evolve."

He stayed up all night until dawn.

The seventh day has finally begun!

However, it did not start to evolve animals on the seventh day as Xu Zhi thought, but ushered in another terrifying mass extinction!

Because the sun rises.

At the moment of sunrise, all kinds of blue moon grass in the prosperous ocean 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, they sank to the bottom of the sea.

In an instant, the blue moon grass began to go extinct on a large scale.

"The second mass extinction, it broke out so soon, and it didn't take long for it to survive, it was absolutely tragic."

This is the death of life.

In the long evolutionary era of species, in units of billions of years, countless species were born and extinct, which is a vast epic of the planet.

The spore's evolutionary life process is long and rotten, but at this time, in just a few hours, countless prosperity and decline are displayed in front of the eyes, and the shock to Xu Zhi is powerful and inexplicable.

By the afternoon, a touch of blue gradually came back to life from the dead plants.

It was a five-star-shaped blue moon grass, which also ushered in its own mutation and 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, they died, were reborn, and reproduced for countless generations. They began to gradually darken from blue to purple and black. Finally, a mysterious black-blue pentagram seaweed was formed.

It has five-pointed star beautiful mysterious balanced leaves, which can be stretched and opened.

At night, the five horns are opened, flat on the sea surface, and the area that absorbs the moonlight is increased.

A bit of a mimosa pattern.

The mass extinction is a demise and an opportunity for the rise of weak species.

In the entire ocean, no species competed with it for the living environment, and it began to multiply rapidly again, multiplying various side branches, and filling the entire ocean vigorously.

"Get through five thousand years of scorching sun and five thousand years of dark night."

"For five thousand years, the sun and the moon are in the sky. As the only living creature of countless species, you have experienced the scorching sun and darkness. You are a real hero. Let's call it Zizhucao." Xu Zhi smiled, silently picked up the pen, and turned the black Diary page two.

Continue to record the second mass extinction event in the evolutionary history of the biological era that belongs to him:

[In the Guangwu period, the sky and the earth changed suddenly, the moon set and the sun rose, and there was a scorching sun that lasted for 5,000 years. The blue moon grass overlord who had survived the dark martial period began to go extinct on a large scale. Zhaocao rose up into the sky and became the protagonist of the era that dominated the era]
