"Wait!" Ding Yue said with a shocked face: "Doctor Su, do you mean that the giraffe will become like this, it has been a fixed thing a long time ago?" Didn't it evolve little by little? ”

Su Yuan nodded: "For now, that's the case." ”

"How is this possible!"

"Listen to me." Su Yuan smiled.

"You say, you say."

Su Yuan continued: "The ancestors of giraffes are called Siwa deer, their necks are very short, not long, if according to Darwinian evolution, then between Siwa deer and giraffes, there should be a species called giraffe." But archaeological evidence shows that it does not exist, so the Siva deer directly turned into a giraffe. ”

Everyone had the expression of a mother's selling.

"I know you guys think it's weird, I'll explain it soon."

Su Yuan sorted out the thoughts in his head, and then said: "In essence, the Siva deer will not actually become a giraffe, just like the jellyfish in the sea, it is still like that for hundreds of millions of years. However, the presence of the virus has caused the mutation of the Siwa deer. ”

Su Yuan said: "Because only the virus can explain why the Xiwa deer turned into a giraffe." Of course, there is not much conclusive evidence for the evolution of viruses now, but it does exist. So what I'm talking about is just an inference. ”

Everyone listened carefully, and no one wanted to interrupt.

Su Yuan continued: "Do you remember what I just said, for a giraffe to become what it is now, it must be equipped with many things, such as a heart, strong limbs, and a maze net, all of which are used to protect its long neck from problems. So little by little evolution is impossible, and it can only grow into a giraffe if it is determined from the beginning that it looks like this. It's like a program, it's already been programmed and can only be shown at the end. ”

"It's impossible for me to grow strong limbs for you to grow your neck, it's impossible, right, if that's the case, the giraffe won't exist."

"So you have to design it to look like this from the very beginning, so that it can look like this. As for what is the source? It's our DNA, our genetic material. ”

"Then why did the Siva deer turn into a giraffe? It was because of the virus, an RNA virus, that infected the Xiwa deer, causing the Xiwa deer to mutate genetically and become a giraffe. ”

"The most important thing is that giraffes are the product of group variation, and all giraffes emerged at the same time. And the virus is a thing that can just be transmitted in one ethnic group, basically one is infected, it will infect a large area, and all the Siva deer are infected, and the next generation will become giraffes. ”

"So, when the Siva deer becomes extinct, the next will be giraffes."

"It's all Lee Kwang-so?"

“？？？” Su Yuan looked confused.

After talking so much, Su Yuan's mouth was dry, he drank a sip of water, and he continued: "Let's talk about zombies, in fact, zombies may be infected with a mutant virus, causing everyone to become zombies, and in an instant, the group mutates. It is possible that the purpose of these viruses was not to turn humans into zombies in the first place, but perhaps to make humans stronger. ”

"Becoming superpowered?" Fan Deyu smiled.

"Yes, it may be in this direction, but unfortunately, in the end, this virus turned all humans into zombies, and everything went in a bad direction."

"Then why haven't we changed?" Gu Jingman asked.

Face this problem.

Su Yuan was silent for a long time and said, "Because of luck." ”

That's a really good answer.

Su Yuan clapped his hands and said with a smile: "Okay, that's all for today's story, let's talk about it if I have the opportunity in the future." ”

Everyone is still unsatisfied and finds it very interesting.

Su Yuan was a lot more relieved about their reaction, at least everyone had hope of survival.

As for what the future will be, there is really no need to think about it, it is easy to get annoyed if you think too much, after all, no matter how you think about it, computers and mobile phones will not come back, and all attention needs to be focused on livelihood.

Staying alive is the real goal.

Thinking of this, Su Yuan suddenly remembered a theory in a previous book.

Survival is the first element of civilization, and civilization is constantly growing and expanding, but the total amount of matter in the universe remains the same. The universe is a dark forest, and every civilization is a hunter with a gun.

Bringing it into the present, it is that survival is the only purpose of human beings, and when the total amount of material is decreasing, self-survival and security are even more important, and resources are always the reason for war.

Come to think of it.

Su Yuan was cold and creepy.

"Hey, why do you want to do so much." He patted his cheek, trying to keep himself focused on the moment.

…………

…………

Dead.

Su Yuan hugged his wife and slept on the bed in the dormitory, which was a little crowded......

"What you talked about today is quite interesting." Ji Shishi said with a smile.

"Really? When I used to learn these things, I thought it was quite boring, after all, I had to memorize them, and I had to take exams or something, which was very annoying. Su Yuan recalled the situation when he was a student, it was really difficult, and he didn't know how he persevered.

Ji Shishi said: "In the future, you can tell more stories, I want to hear it." ”

"Okay."

The husband and wife's night talk is as plain as water.

Ji Shishi said: "I don't know whether to be happy or sad. ”

"Huh?"

"Do you know how sad it was for me to be alone at home when you used to work overtime? At that time, I was pregnant, and you were still working overtime, and you didn't care about me. ”

Su Yuan said, "I'm sorry......"

"At that time, I was very easy to think too much, and I was still thinking, will you cheat behind my back? But when I think that you are in the hospital, there are so many patients in the hospital, where is the time to cheat, it would be nice to have time to sleep, I guess you can't even recognize the little nurses in the hospital. Am I right? Ji Shishi asked.

Su Yuan suddenly became embarrassed, those things at that time had already passed.

He was a little flustered, Ji Shishi said these words, was he testing himself? Or is it just complaining?

"I'm sorry I was negligent at that time."

"I don't mean to say that you're bad, anyway, you have time to spend with me now, and you'll stay with me as long as I want, right?"

"Well, I'll always be by your side." Su Yuan hugged her tightly.

At this time, he remembered the dead Liu Yu in his mind, and immediately shook his head.

At this time, Ji Shishi sat up, got out of bed, and went into the toilet.

But after a while, Ji Shishi shouted: "Husband, come here." ”

"What's wrong?" Su Yuan climbed down from the bed in confusion and came to the toilet with a flashlight.

I saw Ji Shishi turn her head helplessly and said, "There is no water." ”

Su Yuan looked at the faucet that was turned on, but not a drop of water leaked from it.

He knew that trouble was coming.
