Shepherding Humanity - Chapter 4

[Chapter 4 Ocean Oxygen Rising, Animals Appear]

The scorching sun of the sixth day passed, and the night of the seventh day came, and the turmeric still lives in the ocean with peace of mind.

It eliminated 99% of species, successfully survived the second mass extinction, dominated the entire ocean, and became a perfect species that survived completely in the harsh environment of 5,000 years of alternating sun and moon.

At the same time, along with its large-scale reproduction, the photosynthesis of aquatic plants has increased dramatically, and the oxygen content in seawater has greatly increased. Oxygen, the conditions suitable for the birth of marine animals, are already available.

Soon, some invertebrates began to appear in the ocean, a group of black beetles, similar in shape to the ancient species, the plate-footed horseshoe crab.

At this point, marine animals have entered the historical stage of the evolutionary era. After the Guangwu Period, plants survived completely and stably, and the creatures in the sand table also ushered in a big explosion, and the species diversified.

“Animals, finally appeared, I have been waiting for you for a long time, waiting for two mass extinctions.”

The moment he saw the animal appeared, Xu Zhi showed a gratified smile. After a day and night, his tired body finally couldn’t bear it anymore, so he went straight back to the room, lay down and fell asleep.

When he woke up, it was already the eighth day of the creation of the spore’s evolutionary sand table.

“Ah, wash your face and brush your teeth.”

Xu Zhi got up from the bed, his stomach was really hungry.

Suffering from a terminal illness, if he does not take care of his body, he is simply courting death. After he left the compound, he rode a bicycle again, facing the bright sunshine, on a small road in the country, with neat farmland on both sides, and the air was indescribably fresh and natural.

He ran out to the county, made a breakfast before coming back, and when he returned to the orchard yard, it was already past nine in the morning.

He continued to look at the sand table.

After one night, a miniature ocean of more than 40 square meters that is comparable to the size of a swimming pool has undergone drastic changes. The ocean is full of vitality, and marine animals have existed everywhere.

As the ancestor of plants, Syphilis has evolved into various strange-shaped marine plants, and even some marine plants can no longer see the form of their ancestors.

As a plant overlord, the entire marine plants are its descendants.

As for those marine animals, the overlords use arthropods as the apex of the food chain. They have a solid shell and are the strongest armor without any natural enemies.

Among them, the strongest branch is an insect similar to the ancient trilobite, which dominates the ocean.

They were the first creatures to have evolved eyes, a visual system, and a sturdy shell, and any animal or plant is their prey!

“This has evolved equipment that surpasses the times – eyes…” Xu Zhi came back from breakfast and was shocked when he saw that a creature had evolved eyes.

Living things basically have eyes, this is modern common sense.

However, in the Cambrian period, in the marine explosion species, everyone was blind, and all creatures had no eyes. They swam blindly in the sea and evolved powerful equipment such as eyes. It is not too easy to beat a group of blind people. To the top of the food chain, to the pinnacle of life.

Species with eyes are invincible in the food chain, and they began to multiply in large numbers. Those species that cannot evolve eyes are quickly eliminated. The entire ocean will soon enter the era of “eyes” for all people.

But the era of these invertebrates with eyes did not last long. It was another five thousand years of sun and moon alternation. On the ninth day, another ancient overlord, vertebrates, appeared.

Xu Zhi could clearly see that it was a black fish in the sea!

If it is said that most invertebrates in this era have a layer of exoskeleton armor wrapped around their meat and have extremely strong defenses, then vertebrates have soft meat wrapped around their bones.

They seem stupid, but they do the opposite. They put their weakest flesh on the outside and their hardest bones on the inside. They can have vertebrae, and the biological structure of the internal skeleton can be extremely dexterous.

“You have a meat suit, full body armor, slow speed, but others are smart and have no defense,

But you have the backbone, you can’t run away, you can’t eat.

“Xu Zhi sat on the chair next to the ocean, slashed the apple, looked at this scene, and suddenly laughed, it felt very interesting and a very reasonable evolution.

The two sides are still evenly matched.

On the tenth day, the balance was broken.

A red vertebral fish has evolved jaw teeth and became the world’s first jawed fish.

It spreads the backbone, the backbone that supports flesh and blood, to the head. The bones at the top of the spine are placed at the throat, forming hard teeth that can easily crush the armor of those animals.

On animals, the second terrifying cross-century equipment – teeth, also appeared!

In an instant, teeth, the strongest weapon in this era, after eyes, changed the entire marine ecosystem.

The ancestors of the armored trilobites, shrimps, and crabs were all preyed on one after another. Their invincible shell defenses were broken open, revealing the tender meat inside, and the carapace was no longer invincible.

On the tenth day, the era of domination of vertebrates…. has come completely!

This fish has a mouth and uses its spine to swim and flick its tail. It is already a real fish.

It is not only the ancestor of fish, but also the ancestor of all vertebrates, as well as the ancestor of man.

Even today, hundreds of millions of years later, lions, tigers, humans, elephants, whales, sharks, and any powerful creatures standing at the top of the food chain are, without exception, vertebrates.

And this fish is still swimming leisurely in the sea, and he still doesn’t know what brilliance he has laid for the future era of brilliant civilization!

“There are already animals. They chose to leave their mothers and give birth to the origin of life – the ocean.” Seeing this, Xu Zhi found that there were already marine animals, and they began to not satisfy the fierce competition in the ocean and evolved into amphibians. Life on the deserted coast.

The marine plants in the sea also began to climb ashore and became terrestrial plants, and the barren and yellowed land was full of greenery.

However, due to Xu Zhi’s genetic limitations, the direction of their evolution is all ant-sized shapes, and even the largest plant is the size of a finger.

After all, being huge is not being powerful.

The mother nest of the previous generation also explained before its death that some small and mysterious bodies can also have the energy to destroy the world. Concentration is the essence. .

These tiny super-Paleozoic species have extraordinary potential!

Seeing this, Xu Zhi recorded the next page of the Guangwu Period with delicate handwriting. This evolutionary era, he named it the Cenozoic:

“Cenozoic, the era ushered in a new life, all kinds of animals exploded, the first batch of marine animals appeared, species flourished, and groups of heroes competed for beauty. Vertebrates were born, and with their dexterity, they were defeated, and vertebrates became the overlords of the Cenozoic, and they will rule a long and vast era!”

After Xu Zhi finished writing everything, he silently closed the book.

He also turned his head and left the competitive sand table.

“It’s so fast, I’m going to have a breakfast, the spores will soon go out of the ocean and evolve terrestrial species…”

The spore cells of the worm nest, even if they are only given such a small place to multiply, have also achieved species diversity and formed a preliminary ecological circle.

Xu Zhi suddenly raised his brows, “However, to evolve intelligent creatures, I don’t know how many long epochs it will take. Now that the ecosystem has appeared, it’s better than me…”

“Do something?” He was playful, looked at his fingers, and wanted to cut his hand and drip blood into it, so that some species could absorb genes and quickly evolve into human-like intelligent creatures…

But he thought about it, and then rejected it. Some resisted experimenting with people. “Remember that there is a zoo in the urban area outside. We secretly made some orangutan furs and got some genetic templates…”

He went straight out.
