In order to survive.
Noah began to reduce the consumption of exercise and try his best to keep his cells in a dormant state!
That's right.
With this method, Noah successfully evolved an ability and became the earliest " variable temperature animal "!
To put it simply, it was to rely on one's own behavior to regulate the distribution of body heat or to absorb heat from the external environment to increase one's body temperature.
In this way, he could reduce a large amount of energy consumption. Then, he could eat less and sleep more, reducing the chemical reactions in the body, thus reducing the power consumption to the minimum.
Later, a species of chordate imitated Noah's method and successfully evolved into the future of humans.
Its name was the Cave Salamander.
This dragon-like earthworm lived in underwater caves. Under such extreme conditions, food was very limited, so the cave newt could live without food for up to ten years, becoming the world's most hungry animal.
......
Gradually.
150,000 years later.
At this time, the average temperature on Earth had dropped to only 5 degrees Celsius. More than half of the creatures had gone extinct in the cold, and the remaining creatures were struggling to survive.
Then, another 50,000 years passed.
At this time, the Ice Age finally came to an end, but the signs of life on Earth had almost completely disappeared. The originally vibrant oceans had become lifeless, and only a portion of the algae continued to reproduce, desperately trying to repair the food chain.
During this period, the Earth would need hundreds of thousands of years to recover its former vitality.
Finally.
Time flew by.
It had been 400,000 years since the gamma-ray burst hit Earth, and the disaster was basically over.
This catastrophe that swept across the entire world was the first mass extinction in Earth's history. The straight-shelled nautilus miraculously survived, but it had a bad genetic mutation and shrunk to two meters.
After all, they had starved quite a bit!
The straight-shelled nautilus was no longer the overlord of the ocean. It was quickly replaced by the plate foot horseshoe crab as the new top predator after the disaster.
At the same time, there was another beneficiary of this disaster, and that was the Star Turtle, one of the earliest vertebrae like Noah.
The Star Turtle belonged to the head turtle class and did not have a jaw. After the disaster, their branch evolved into the earliest spine with a jaw, the " stickleback fish."
Suddenly, one day.
When the land is gradually covered with plants
The deadly rays, severe famine, toxic gases that blotted out the sun, and a severe ice age formed a mass extinction event. After hundreds of thousands of years of repair, it finally recovered its vitality from the past!
Gradually, the voice in his mind rang out.
[System Notification: Congratulations to the host for completing the " Ordovian " challenge!]
"Is it finally over, the mass extinction?"
Noah seemed to still be in shock. Then, he looked at the current time.
Time: Silurian
[Location: Giant God Sea, the deep sea intersection between the Baltika and Laurencia continents.]
[Character: Unnamed Vertebral Creature Growth]
[Main Mission: Evolve into Godzilla and become the king of monsters.]
[New Version: Terrestrial Plants, Higher Vertebrates, Insects, and Arachnid Arachnids (Late)!]
[System Notification: This version belongs to the transition stage, the third era of the " Early Palaeoera ".] Host, please enjoy the current peace. There are 30 million years left until the next update of the Devonian Era.
......
Another few million years passed by in a hurry, and the dead algae were once again given a new round of vitality!
Earth was trying its best to heal its wounds, and the atmosphere was gradually recovering.
The ice began to retreat to the north and south banks, forming the South Pole and the North Pole.
The radiation contaminated matter began to settle down, and the planktons once again nurtured a large number of new lifeforms.
Every species that could survive to this day was a chosen one. Every single one of them had experienced countless coincidences and overlapped with the choices of a great destiny.
Facing the first round of shuffling in the world, all kinds of creatures that survived would embark on a new journey and start a long road of evolution.
The duration of the Silurian period would be very short!
The next version would be a major update.
With the appearance of the amputated animals, the last three eras of the Phanerozoic-Palaeoera were included. Devonian, carbonatite, and permian!
After that.
They were the well-known three geological eras of the "Middle Ages": The Trias, the Jurassics, and the Cretaceous periods.
During this period, the dominant animals were reptiles, especially dinosaurs. Therefore, it was also known as the era of reptiles and the era of dragons!
Therefore,
Looking forward to it!
Survivors of this planet, let's witness the birth of a great king!
