In his spare time, Shen Cong likes to read books and videos about biology. Pen, fun, and www.biquge.info

Some time ago, he watched a documentary, which recorded the research data of the Chengjiang biota, and restored the explosive evolution of the colorful biota during the Cambrian explosion of life 542 million to 530 million years ago through special effects technology.

The discovery of the Chengjiang biota posed a major challenge to Darwin's theory of evolution, which many biologists believe is not always correct. Even religion has been mixed in, and various creationism theories have been proposed, believing that it was the gods who created the Cambrian explosion of biodiversity.

However, with the correct understanding of geology and paleontology, combined with the fact that the Cambrian explosion occurred in a period of one or two million years, this is not only not a refutation of the theory of evolution, but a powerful supplement to the theory of evolution.

Because during the Cambrian period, the earth's temperature increased, organisms recovered, oxygen was abundant, ozone was formed, volcanoes were frequent, marine nutrients were increased, phosphate rocks were formed during this period, and males and females appeared, all of which contributed to the explosion of organisms.

On July 1, 2019, the 35th anniversary of the discovery of the Chengjiang biota, the Chinese scientific community revised the translation of "evolutionary theory" to a more reasonable "evolutionary theory".

Since 1859, Charles Darwin published his classic masterpiece "The Origin of Species", prompting people to think about the very philosophical question of where they came from.

The theory of "punctuated equilibrium" was proposed: "The evolution and evolution of living things are not always gradual, but a process of gradual and leapfrogging. ”

……

The reason why he thought of the theory of evolution was that Shen Cong saw the changes in the body of the pearl old mussel.

He dissected a lot of pearl mussels, scooped up the pearls, and also peeled off the whole active core mussel shell. Therefore, he can clearly see that there is a clear boundary between the mussel shell and the mussel meat.

The active core is a relatively independent tissue site with special properties in the organism.

Because it is mostly a whole bone, it gradually becomes the active core of a semi-metal, so the boundary is obvious and can be easily peeled off.

But in the body of the pearl old mussel, Shen Cong saw that this boundary was blurring.

The part of the mussel meat connected to the mussel shell has shown signs of metal gradation, which is stuck to the mussel shell and cannot be peeled off well.

In other words, the active core has "eroded" into the body tissues, and the flesh at the junction has begun to metallometre, and the flesh farther away also shows slight signs of metallic gradation.

It's like cancer cells are spreading, and the whole body is cancerous.

Shen Cong cut off a piece of metal gradient mussel meat, and under his perception, there was indeed a slight reaction that belonged to the active core in this piece of mussel meat - the rate of activity loss slowed down, and after injecting the activity, it could also provoke a slight sharpening reaction.

And the peculiar thing is that this piece of mussel meat has not become hard, and it still maintains the same softness as the normal mussel meat around.

The difference is that when this piece of meat is cut, there is a kind of blockage in cutting the metal.

"Is it the softness of muscle and the hardness of metal?" Shen Cong's brows were tightly locked, and he didn't know how to react for a while, and his mind was a little confused.

He has dreamed of the Lv1 era many times, including fantasizing that all living organisms have turned into metal, and that metal bumps walk on the ground one by one...... But when I really saw this sign, I panicked in my heart.

The active core of the pearl clam has begun to erode the surrounding tissues, and the whole body is also slightly "diseased", which is indeed from an organic life form to an inorganic metal form.

"Metallic life."

"Is this the direction of evolution in the Lv1 era?"

"The veins of the bark and leaves of plants have undergone a metallic gradient, the active core of animals have undergone a metallic gradient, and now even the body tissues have begun to metallometre...... Mutants can change like this? So what about Iron Man, why am I one with a metal machine, life? ”

"Isn't it true that one day, I'll also become an 'iron man' of real metal?"

There was no answer to the question, Shen Cong removed the three jacks, put the pearl old clam to close the clam shell, and returned to Donkey Kong with a piece of mussel meat with a metal gradient.

Throwing the mussel meat on the laboratory table, Shen Cong dragged a chair over and sat on it, sorting out his chaotic thoughts.

……

Shen Cong's first thought was the theory of evolution.

Thinking of the Cambrian explosion of life, in just over 20 million years, life went from the deep sea to the shallow sea, adding countless species, providing ample evidence for the theory of punctuated equilibrium.

According to the theory of punctuated equilibrium, the evolution of organisms is not a slow and continuous gradual accumulation process, as Darwin said, but a process of alternating long-term stability and short-term upheaval, thus leaving many gaps in the geological record.

"Right now, the Earth is in the midst of a brief upheaval, right?"

An extinct meteor shower brings activity, and the appearance of activity changes the stability of the metal, either corroding, rusting, or activating. At the same time, it also changes the compositional characteristics of living organisms, associating the organic structure of life with metals, and gradually gradually changing towards metals.

The only pearl clam that has reached the LV1 era, the active core composed of all-metal, begins to erode body tissues.

Shen Cong immediately thought of the horn-like protrusions of the golden Jiao and the tail whip of the swift leopard.

The angular protrusions are like muscles gradually changing to metal, while the tail whip is a metal gradient between the bones and the skin and flesh on the outside.

These can be seen as the active core is eroding the body's tissues.

"So is the metal change an evolutionary continuation of the new life, or is it a disease heading for destruction?" Shen Cong was a little unpredictable about the mystery, and he couldn't imagine how he could survive when his whole body turned into metal.

But he didn't dare to guarantee that metal life would not be alive.

Donkey Kong has come back to life, and the failed metal lifeforms have also come back to life, and if the scalability is strengthened again, it may not be possible for a free-moving metal form of life to appear.

Now in the new world, the old order has been overthrown.

It seems to be another Cambrian explosion of life, and the same is the rapid emergence of different kinds of life, countless evolutionary beasts and evolutionary trees, emerging in endlessly.

There are evolutionary strong people who have reached the top of the food chain, there are evolutionary weak people who have fallen prey to predators, there are evolutionary people who have not evolved rationally and have been eliminated, such as hideous cats, and there are ordinary creatures that have not evolved and gradually disappeared.

It's like shuffling, erasing the old and shaping the new.

Life has taken a new leap forward.

Zhao Kan said that the future era will be the era of new evolutionaries such as Xiao Li Du, and they even include Shen Cong, who are ancient products of the old era, and may one day be completely eliminated and become archaeological research materials.

Shen Cong was somewhat convinced now.

"It's just that what kind of form is the iron man, the iron man and the mutant, who is the 'Yunnan worm'?" (To be continued.) )
