Chapter 591: Know the bat correctly

"[567中文www.yue20.com] Awei, I beg you, take it away!"
"too ugly!"
"It feels like biting at any time!"
"I can't take it anymore, just slip!"
Many female fans feel uncomfortable.
But at this time, the atmosphere in the live broadcast room reached its climax. Male audiences like to torture female fans. The greater the reaction of female fans, the happier they feel.
Liu Wei shook his head and smiled seriously, saying: "Brothers, bats have been living on the earth for 88 million years and belong to the same generation as dinosaurs.
The dinosaurs were extinct, but the bat survived.
There are now 961 species of bats on earth. They are the most numerous and widely distributed mammals on earth, except humans.
It accounts for about 20% of the total mammals. "
"No! So much!"
The audience questioned and wondered one after another.
If the number of bats is as much as Liu Wei described, why is it rare in life?
Liu Wei looked at the barrage and explained: "At 80 million years ago, bats were used as food by pterosaurs and various birds and beasts. They belonged to vulnerable groups. Later, they found that hiding in caves can avoid being eaten and gradually get used to caves. life.
This habit makes them realize that they can better avoid the attacks of natural enemies.
Similarly, after the appearance of primates, bats also regarded primates as natural enemies, including now.
However, the habit they have cultivated for thousands of years is to avoid enemies, so bats will choose to live away from natural enemies. "
"If humans and other mammals can enjoy the moisture of the sun, then bats enclose themselves in a dark space.
50 million years ago, primates appeared, and at this time, bats have evolved into advanced animals that can reach most parts of the earth, flying in the air, overlooking the reproduction and development of primates.
But they did not take the initiative to bring harm to any primates, otherwise there would be no humans today.
It can be said that bats watched the generation and reproduction of human beings.
We deserve to be called elders! "
"Hahahaha, grandpa?"
"Bat: I thought that when you humans were monkeys, I had lived on the earth for tens of millions of years!"
"Bat: The ridiculous human, actually thinks he is the most advanced animal."
"Bat: Be careful I release the virus!"
Liu Wei looked at the barrage and said with a smile: "Brothers, it is not an exaggeration to call the uncles in order according to the evolution of the species of the earth.
We all know that there have been a total of five species extinctions on the earth, including the huge natural disaster 65 million years ago. More than 90% of the creatures disappeared from the earth and survived, and the best is the bat. . "
"Awesome!"
"The desire to survive is extremely strong!"
"I didn't expect you to be such a bat!"
"I have to say, I admire it a little bit, and actually survived several biological extinctions!"
Liu Wei: "Recently, I saw a promotional video about the bat's self-report. I have to say that the video has been produced very well, giving us a deep reflection on humanity.
I guess many viewers who have watched the video must be shocked by the large amount of viruses carried in the body of the bat.
In fact, humans, like bats and all animals, have microorganisms in them, both inside and outside the human body. The number of microorganisms in humans exceeds the number of known cells in the human body.
Different parts of the human body are distributed with different microbial communities, which have different effects on our body. We divide microorganisms into eight types: bacteria, viruses, and fungi.
Viruses are a kind of relatively primitive, life-like, non-cellular organisms that are capable of self-replication and must be parasitic in cells.
Like all living things, the virus has its own genes. It can replicate, evolve, and depend on biological entities to exist. Its integral life activities are carried out in the host's cells.
A large number of microorganisms coexist inside and outside the bat's body, including viruses. These viruses initially killed bats, but later bats produced antibodies with them in the process of genetics and mutations.
The virus did not die, but was housed in the bat, and no one could do anything. The expansion of the virus was suppressed, and the bat became the host of the virus.
The winged hands of the bat play an important role in suppressing the virus.
The insertion of the unique three amino acids in the MHCI class of bats leads to the extension of the α1 helix, and finally forms a unique "surface anchor", which enhances the stability of the peptide binding, and finally achieves the effect of limiting the immune escape of the virus.
In addition, in the long-term evolution and mutation process, bats have strong DNA damage repair capabilities and a high level of innate immune system.
Be aware that every virus lurking in a bat can be fatal to another organism.
The bat itself is the natural host of more than 100 strong viruses, and the source of transmission has become those animals that feed on it, mainly monkeys, civet cats, lemurs, raccoons, possums, cats, raptors, snakes, Among them, birds and snakes are the main predators.
So we can see that there is basically no direct connection between bats and humans, just like I have caught the most fierce dog-headed bat now, as long as it is prevented from being scratched or bitten by it, it will basically not spread the virus. .
I have just seen a lot of barrage of cursing bats. Here, I would like to ask everyone, why do you have such an idea?
Scared you because of its ugly appearance?
Or is it because you think it is a low-level creature?
People have evolved earlier than humans on the earth. People are poisonous and invade. People live in places that are difficult to find. They almost never disturb your site. People eat insects to maintain ecological balance.
Why do we have the right to insult it?
This is also the place where the public welfare video touched me the most. "
The barrage gradually slowed down.
The audience was infected by Liu Wei's emotions.
The atmosphere at this moment is more like a touching speech.
"Suddenly ashamed!"
"It's not easy for a bat! It just wants to find a place where no one wants to live!"
"Ah~, uncomfortable! Don't know what to say?"
"Thank you Awei, let us know the creatures like bat correctly!"
Liu Wei put away his excited emotions and smiled lightly: "Brothers, we must know the fact that this earth is not just our human beings. We live on this earth with many animals and plants.
The so-called common life refers to each area and boundary, or we can be understood as their own living space.
While enjoying our living space, we must not trample on the living space of other creatures.
To be honest, human beings are too strong.
We need to reflect!
The protection of wild animals is not just a manifestation of love, but our deeper understanding of the world. We must not only live by ourselves, but also survive other things. Only in this way can we achieve sustainable life. "
