The scorching sun of the sixth day passed and the night of the seventh day came, and the chrysanthemum still lives in peace in the ocean.
It eliminated 99% of the species, successfully survived the second biological extinction, and dominated the entire ocean, becoming the perfect species to survive completely under the harsh environment of 5,000 years of alternating sun and moon.
At the same time, with its massive reproduction, the photosynthesis of aquatic plants has increased dramatically, and the oxygen content in seawater has increased significantly. Oxygen, which is suitable for the birth of marine animals, is already available.
Soon, part of the invertebrates began to appear in the ocean, a group of black beetles, similar in shape to the ancient species, the horseshoe crab.
So far, marine animals have entered the historical stage of the evolutionary era. After the Guangwu Period, the plants completely survived steadily, and the creatures in the sand table also ushered in a big explosion and diversified species.
"Animals, finally appeared, I have waited for you for a long time, and waited for two species extinctions."
At the moment when he saw the animal, Xu Zhi showed a gratifying smile, and his tired body after a day and night was finally unable to carry it. He went directly back to the room and lay down to sleep.
He woke up, already the eighth day of the evolution of the spore sand table.
"Oh, wash your face, brush your teeth."
Xu Zhi got up from the bed and his stomach was really hungry.
Suffering from terminal illness, and no longer taking care of his body, he was just looking for death. He went out of the compound, rode his bicycle, and faced the bright sunshine, on the country road, on both sides of the neat farmland, fresh and natural that the air could not speak.
He ran out to the county and got a breakfast before returning. When he returned to the orchard yard, it was already more than nine in the morning.
He continued to look at the sand table.
After a night, more than forty square meters, a miniature ocean the size of a swimming pool, has changed drastically. The ocean is full of life and marine animals are everywhere.
As an ancestor of plants, the chrysanthemum has evolved various odd-shaped marine plants, and even some marine plants, can no longer see the shape of the ancestors.
As a plant overlord, the entire marine plant is its descendant.
For those marine animals, the overlord takes arthropods as the apex of the food chain. They have strong shells and are the strongest armor without any natural enemies.
Among them, the strongest one is a kind of insect similar to ancient trilobites, which dominated the ocean.
They are the first creatures that have evolved their eyes, have a visual system, and have a solid shell, and any animals and plants are their prey!
"This evolved equipment that transcends the times-the eyes..." Xu Zhi came back after breakfast, and was shocked to see that some creatures had evolved his eyes.
Creatures basically have eyes, which is modern common sense.
But in the Cambrian, marine outbreak species, everyone is blind, all creatures have no eyes, swimming blindly in the sea, evolved such powerful equipment as the eyes, and beating a group of blind people, it is not too easy to board immediately At the top of the food chain, go to the peak of life.
Species with eyes are invincible in the food chain, and they began to multiply in large numbers. They quickly eliminated those species that could not evolve with eyes. The entire ocean soon began to enter the era of "eyes" for all people.
But these ages of invertebrates with eyes did not prosper for long. It was another 5,000-year cycle of the sun and the moon. On the ninth day, another ancient overlord, a vertebrate, appeared.
Xu Zhi clearly saw that it was a black fish in the sea!
If it is said that most invertebrates of this era have a layer of exoskeleton armor wrapped in flesh and extremely strong defense, then vertebrates are soft flesh wrapped in bones.
They seem stupid, go the opposite way, put their weakest meat outside, and the hardest bone inside, they can have vertebrae, and the biological structure of the internal skeleton is extremely dexterous.
"You come out of flesh suits, full body armor, slow speed, but people are smart and have no defense,
The two sides are still in an even position.
On the tenth day, the balance was broken.
A red spine fish has evolved its lower jaw teeth, becoming the world's first jawed fish.
It spreads the backbone of the flesh, the spine, to the head. The bone at the top of the spine is placed in the throat, forming hard teeth that can easily crush the armor of those animals.
On animals, the second horrible cross-century equipment, teeth, also appeared!
In an instant, the strongest weapon in the era of the tooth, after the eyes, changed the entire marine ecosystem.
The ancestors of trilobites, shrimps, and crabs in armor were all preyed, and their invincible shell defenses were broken, exposing the tender meat inside, and the carapace was no longer invincible.
On the tenth day, belong to the era of vertebrate dominance.... Completely coming!
This fish has a mouth and flicks its tail by swimming in the spine. It has been regarded as a real fish.
It is not only the ancestor of fish, but the ancestor of all vertebrates, but also the ancestor of humans.
Even today, hundreds of millions of years later, lions, tigers, people, elephants, whales, sharks, and any powerful creature standing on the top of the food chain are no exceptions. They are vertebrates.
And this fish swims leisurely in the sea, and I don't know how brilliant he has laid for the bright era of civilization in the future!
"It has already begun to have animals, and chose to leave his mother to conceive the origin of life-the ocean." Xu Zhi saw this and found that there were already marine animals, which began to dissatisfy the competitive ocean and evolved into amphibians. Living on the barren coast.
The marine plants in the sea began to climb to the shore and became terrestrial plants. The barren and yellow land was full of greenery.
However, due to Xu Zhi's genetic limitations, they evolved in the shape of ants, and even the largest plant was the size of a finger.
After all, huge is not powerful.
The mother nest of the previous generation also explained that some tiny mysterious bodies can also have the energy to raise their hands to destroy the world. Concentration is the essence, and the compression of the body quality of life will cause qualitative changes.
These tiny super-paleozoic species have extraordinary potential!
Seeing here, Xu Zhi recorded the next page of the Guangwu Period with Qingxiu's handwriting. This evolutionary era, he named it the Neogene:
"The Cenozoic era, the epoch ushered in a new life, all kinds of animals broke out, the first batch of marine animals appeared, the species was flourishing, the males were flamboyant, and the invertebrates relied on the carapace to dominate the waters for a while and became the lord of the era. The vertebrate was born and defeated with dexterity. The vertebrate became the overlord of the Neogene and will rule a long and vast era!"
Xu Zhi finished everything and silently closed the book.
He also turned his head and left the highly competitive sandbox.
"It's so fast, I'm going to eat a breakfast, spores, will soon go out of the ocean, evolved terrestrial species..."
The spore cells of the worm's nest, even if it was only given to such a small area to reproduce, also realized the diversity of species and formed a preliminary ecological circle.
Xu Zhi suddenly frowned, "However, to evolve intelligent creatures, I don't know how many long epochs are needed. Since the ecosystem has emerged, it is not as good as me..."
"Something to do?" He looked at his fingers, looking at his fingers, trying to cut his hands and dripping blood into it, allowing some species to absorb genes, and quickly evolve humanoid intelligent creatures...
But he thought about it and rejected it. Some resisted taking experiments with people. "Remember that there are zoos in the urban area outside, secretly making a few gorillas' fur, get some gene templates..."
He went straight out.
