The Frenzy Of Evolution

"This is..." Duan Fei, who was confused about these symbols a moment ago, can now understand the meaning of these words. Although he cannot translate them word by word, he can understand the meaning of the entire text. It's not difficult to describe something.

There are two stories described here. The first part is about the illusion of the origin of the earth.

3.5 billion years ago, the earth when life first appeared was completely different from the earth today. At that time, the earth had just emerged from a gas cloud composed of gas, dust and rocks. Although the composition of the atmosphere at that time was uncertain, it was mainly carbon. The composition of the gas is undoubtedly dense carbon dioxide, there may also be methane, and there is no oxygen at all. The sun at that time was also different from the sun now. According to the theory of stellar evolution, the temperature of the sun at that time should be higher than that of the sun now.

The sun temperature is 25~30% lower. In the early days, the greenhouse effect of carbon dioxide in the air around the earth kept the earth warm and life continued. However, as the temperature of the sun increased, the sea water became hotter, and more and more water vapor entered the atmosphere, plus billions of tons of water stored in it. If the carbon dioxide in carbonate rocks continues, the greenhouse effect will eventually get out of control. The earth will be like the current situation of Venus, with the surface covered by thick carbon dioxide gas, and high temperatures can melt lead. Fortunately, about 2 billion years ago, cyanobacteria began to appear in the ocean, which converted carbon dioxide in the air into organic carbon compounds through photosynthesis. Over hundreds of millions of years, cyanobacteria and the plants they evolved into have evolved and multiplied so much that the amount of carbon dioxide in the atmosphere has increased at exactly the same rate as the sun's warming. This theory holds that it is life itself that saves the entire living world.

On the other hand, the earth has never been peaceful since its birth. In addition to various droughts and floods, hurricanes, tsunamis, earthquakes and volcanic eruptions, it is constantly bombarded by rock fragments from space. Most meteorites are small and become harmless meteors, while a few larger ones can reach the ground. About 100 million years on average,

A huge meteorite hit the earth, injecting a large amount of dust and gas into the earth's atmosphere, blocking the sunlight, causing the earth to suffer great disasters, and a large number of species became extinct. The most recent one occurred about 65 million years ago, and caused great damage to the earth at that time. The dinosaurs that dominated Earth's land mass became extinct.

This mass extinction seemed to be the first mass extinction of organisms in peaceful times. However, after the ruins of the ancient gods appeared, humans truly realized that this was the first mass extinction.

Comets not only bring life to the earth, but also threaten existing life on the earth. Comets can give birth to life, gave it to Earth 4 billion years ago, and can continue to give birth to life. These simple life forms may have been brought to the earth by comets, or they may have come to our world due to the dust left in the orbit of comets falling onto the earth's surface. These life forms are alien to us on earth, and they resemble some filtering viruses. Hall boldly hypothesized that these "comet viruses" are out of touch with us advanced earth animals in terms of time and structure. , On the other hand, organisms on earth have no resistance to these "comet viruses".

When a meteorite fell three years ago, a virus descended on the world. The human world was completely overturned. All kinds of creatures evolved crazily. This was the same as the wave of meteorites that wiped out the dinosaurs hundreds of millions of years ago. Same reason.

Did life on Earth originate on land or in the ocean, or was it carried by asteroids from some distant part of the universe? To this day, the origin of life on Earth is still a mystery that eludes scientists. They often hold different opinions and cannot agree on one thing. Our planet formed approximately 4.6 billion years ago, and at some point in time something must have happened as this lifeless body began to receive materials as distinct from rock and water as something.

Nitrogen and carbon molecules evolved into DNA, and a kind of microorganism traveled around the stars in the universe...The undoubted fact is that millions of years after the appearance of this tiny molecule, the original single-cell body was born, and later slowly appeared again They introduced more and more complex aquatic creatures, and they finally landed on land. Since then, various creatures have multiplied and spread on a large scale on the earth.

There are about 2 million different kinds of living things on the earth. However, this is only a number calculated before the end of the world. After the end of the world, this number rises to an uncountable number. Various creatures merge with each other and continue to eat the genetic nuclei of other mutant beasts. After mixed evolution, even the human body has different biological genes, including the gene nuclei of different types of zombies and the gene nuclei of mutant beasts with different abilities. They merge with each other and absorb each other in the human body, transforming into a brand new Mixed individuals.

But all kinds of living things originate from the same substance - a substance that, to some extent, initiates the process of life. What kind of substance is this? This article will elaborate on the latest theories and latest research results about life on earth. Some fragments of celestial bodies wandering in space are like a group of "robbers" in the universe, and sooner or later they will collide with a certain celestial body. But some comets and asteroids that collided with the Earth may have become the creators of life on Earth. It is very likely that a comet brought a large amount of water to the earth. Without water, the earth may always be a dry planet.

Seeing this, Duan Fei couldn't help but wonder. The previous mass extinction of organisms was due to meteorites, and this time the mass extinction of humans was also caused by meteorites. Is there any mysterious connection between them?

At this moment, the second fantasy also automatically started, and scenes of scenes suddenly entered Duan Fei's eyes and came into his mind.

This is a paradise-like beauty. The first thing that attracted Duan Fei's soul's attention was the phenomenon in the air that could not be explained by physics. Floating stones of large and small sizes slowly rotated like tops, and countless iron chains The stones are all connected to each other, and there are all kinds of strange tall plants on the ground. Some plants are more than two hundred meters high, like a skyscraper.

In the clouds behind these scenes, a dreamlike huge island appeared, with tens of thousands of buildings standing on it. The scene was very amazing.

Whoosh! All the illusions were retracted at this moment, and turned into a red symbol floating in front of him again. With a slight touch, Duan Fei screamed as if he was electrocuted.

ah--!
