"Actually, viruses are generally not willing to go into unnatural hosts. Because once it passes, the virus is easy to die, and the virus does not want to die, so sometimes there will be mutations. But there are also two kinds of mutations, one is to be safe, nothing to do, and stay obediently. One is that it will make you cold and fever. ”

"But it's not absolute, some viruses are good for the human body, just like more than 100 years ago, someone discovered that there is a virus that can attack cancer."

"Wow, it's really fake, so powerful!"

Su Yuan said: "This is just an accidental discovery, after so many years, hasn't there been a virus that attacks cancer." ”

"That's a pity."

Fan Deyu said: "I thought of a possibility! ”

"Huh?"

Fan Deyu glared and said: "Didn't there be a movie before, which was about human research on viruses to overcome cancer, which resulted in a zombie outbreak, isn't this very similar to now, Doctor Su, do you say it's not!" ”

Su Yuan smiled: "What you said is not impossible, but we have no evidence now." ”

"So many zombies, that's evidence!" Fan Deyu said without giving up.

Ding Yue glanced at him directly: "Shut up, listen to Dr. Su, what are you talking about!" ”

Fan Deyu suddenly closed his mouth in a daze.

Su Yuan said: "Speaking of this, I think of one thing, this matter may also be one of the reasons why humans have become zombies. What you may not know is that a hypothesis that was put forward in the last century, the theory of virus evolution, of course, has been proven to be true. ”

Su Yuan looked at their puzzled looks, and knew that they must not have heard of this thing.

He continued: "That is, the education we received before, including when we were in school, was it that we would tell you in science class that humans evolved from apes, and Darwin's theory of evolution said that natural selection, survival of the fittest, and genetic mutations caused us humans to become what we are now, right?" ”

Everyone nodded.

"But in fact, this is just a speculation, not a conclusive conclusion, the so-called natural selection of the fittest survival, in fact, is fake, may not exist."

Everyone suddenly looked confused.

"How is this possible?" Ding Yue wondered.

Fan Deyu began to interject at this time: "I know this!" I've seen it when I watched the video before, and many people are questioning whether this theory of evolution is correct. If the theory of evolution is true, then why are there no fossils of species found in the process of biological evolution? Am I right, Dr. Su? ”

Su Yuan nodded: "That's right, that's right, this is also a point of view." ”

Ding Yue was puzzled: "However, hasn't the survival of the fittest always existed, haven't we all been competing before?" Whether it's the college entrance examination or the graduate school entrance examination, it's a single-plank bridge crossed by thousands of troops! ”

Su Yuan said: "What you are talking about is a kind of allocation of social resources and survival relations, which belongs to a social problem and is not within the scope of life. Just because you're admitted to college doesn't mean you'll live a long life, you'll be able to evolve and gain superpowers, you see. ”

"Is that so?" Ding Yue was very puzzled.

Su Yuan didn't continue to delve into it, and then said: "Pull it back, just now when it comes to the theory of evolution, let me give you an example, you all know giraffes." ”

"Uh-huh, yes."

Su Yuan said: "Do you know how the giraffe's neck grows? ”

Gu Jingman said: "Didn't you say that you can only eat the things in the lower places after eating them?" Then the neck becomes longer. ”

Su Yuan smiled: "That's right, that's what the book says, but it's not." If it's just because there is nothing to eat at the lower places, and the necks at the higher places are long, then why are the cows, sheep, and the like that existed at the same time as the giraffes still alive? Has it continued? It stands to reason that the necks of these animals should all become, but why are only giraffes getting longer? ”

Fan Deyu smiled: "Because it's called a giraffe, hahahaha......"

Halfway through his laughter, he found that no one was laughing in the entire dormitory, and he was immediately embarrassed.

Su Yuan continued: "This statement is not true, right, then later, someone said that the giraffe is to avoid natural enemies, in order to run faster, so the legs are long first, so that you can run faster, but after the legs are long, you can't drink the water on the ground, so the neck begins to grow little by little." ”

Ding Yue's eyes widened: "Isn't this more!" Hiding from predators? How can you hide with such a big body? ”

"yes, that's the problem." Su Yuan said: "So Darwin's theory of evolution can't explain the giraffe's long neck. ”

"Also, when the giraffe's neck grows longer, its matching heart also has to be long, including its limbs and body, to become stronger, because only in this way can it withstand this long neck. Let me tell you a little bit of knowledge, do you know what blood pressure is in giraffes? ”

"How much?"

"300, we ordinary people are around 100, and giraffes are three times as many as people." Su Yuan said with a smile.

"That's so high!" Everyone was amazed.

"With such high blood pressure, why didn't its blood vessels burst?" Fan Deyu was surprised.

Su Yuan said: "Here is the key point. Judging from such a high blood pressure, even if the giraffe has a strong heart and strong muscles, but the brain is fragile, it doesn't matter if you usually hold your head up, after all, it is normal for blood to be pumped up. But if the giraffe lowers its head, with such a strong blood pressure, the blood vessels in its brain will explode directly! ”

"Why didn't it explode?" Ding Yue asked curiously.

Su Yuan received: "Because there is a tissue called the maze behind the giraffe's brain, this tissue diverts the blood pressed up by the heart, so the blood vessels in its brain will not burst." This is also where giraffes are magical. ”

After listening to this, everyone was very surprised, and felt that the useless knowledge had increased again.

Su Yuan said: "Okay, giraffe here, have you found any problems?" ”

These people in front of them looked at each other, but they didn't notice it.

Ji Shishi suddenly raised her hand: "I know!" ”

"You say."

"It's weird that a giraffe looks like this!"

Su Yuan smiled helplessly: "Yes, yes, you are right." Let me ask you, the giraffe looks like this, in order to match its long neck, its body has a matching heart, strong limbs and body, and a maze net behind the brain, don't you think it's too coincidental to drink? It's like you can only eat when you eat, eh, just have a pair of chopsticks on the side to match you. Everything in the giraffe is matched, it is all preset. ”
