Chapter 237 Gene mutation! Blues evolution! Step into the realm of top biologists!
When Li Qiwei said that he wanted to perfect the theory of evolution, the whole audience was excited.
Countless people are quietly waiting for his next step.
Pavlo, who had been extremely confident just now, was also panicking at this moment.
He knew that with Li Qiwei’s status, it was impossible for him to speak lies in public.
Under his uneasy gaze, Li Qiwei said calmly and forcefully:
"The core theoretical flaw of the theory of evolution is the problem of natural selection."
"Pavlo and even many people in the academic world believe that : Where do those differential traits available for natural selection come from? Evolution cannot explain this. "
"But what I want to say today is that the basis of natural selection is genetic mutation!"
boom!
This time the venue immediately became commotion.
"Gene mutation? What is a gene?"
"Is this Bruce Lee's strength? I can't understand him when he opens his mouth."
"Good boy , This is a real scientist, really professional.”
“It’s funny, Bruce thought what he said was very easy to understand, but to me, it still sounds like a sacred book.”
The general audience cannot understand it, but those who have knowledge of life sciences or those in the industry are different.
Especially Pavlo, his face turned pale.
He murmured to himself: "Isn't the term gene just proposed last year?"
"Does Bruce even understand such new knowledge?"
"It's just I have never heard of the word genetic mutation.”
In the face of everyone's doubts, Li Qiwei took his time, which was what he expected.
After all, he only came up with this not long ago.
So, next, Li Qiwei started from Mendel's pea experiment and mentioned genetic factors.
He infinitely elevated Mendel's status.
The people present learned from his words that there was such a great biologist at the same time as Darwin.
It’s a pity that the other party has been ignored by the scientific community for more than thirty years!
What a pity this is.
Then Li Qiwei explained the Danish geneticist Johnson and officially changed the name of genetic factors to genes.
At this time, the people in the field understood what genes were.
At the same time, everyone feels extremely familiar with this term.
It’s as if it is inherently hidden in the human brain.
However, more people were shocked by Li Qiwei's eloquence.
Under his explanation, even people who have not been exposed to life sciences can understand such a professional term.
It can be seen that the other party has deep attainments.
Obviously he is a physicist, but he has such a deep understanding of biology.
From his eloquent talk about the pea experiment, everyone could only feel that it was unfathomable.
Bateson, Morgan and others in the VIP seats, even though they knew the results in advance, still felt a sigh of relief when they heard Li Qiwei talk about the history of genetic theory.
In terms of teaching ability, Li Qiwei may have made them even more desperate.
No wonder the other party has been teaching in his own country for several years.
This ability to peel off cocoons and impart knowledge is simply unrivaled.
Several big names in the life science field listened with great interest and did not feel bored at all.
The concept of genes was almost explained. At this time, Li Qiwei continued:
“What is the relationship between genetic mutation and natural selection?”
“It is still based on biological growth. Take teeth as an example. "
"One day, two molluscs went out together to find food, and unexpectedly one of their genes suddenly mutated."
"One of them actually grew a small stone somewhere on its head."
"And the other one grew a hair somewhere on its tail."
“The molluscs that grow stones can crush food better with this small stone, and their eating efficiency is greatly improved.”
“And the molluscs that grow hair find this The hair is of no use, so it just ignores it.”
“It doesn’t matter at first. Although there are stones to help, those molluscs without stones are still alive and well.”
"But there were unforeseen circumstances. An accident caused a sharp decrease in food in the area where the molluscs lived, and famine occurred."
"Soon, all the food they could eat was eaten. At this time, we can only wait to starve to death."
"The mollusk with hair is no exception, and its hair cannot be eaten."
"But the one with stones. The mollusk suddenly discovered that another thing could be its food. "
"And this food can only be eaten through the friction of stones."
"So, it survived tenaciously and continued to reproduce, and more and more of its descendants grew stones."
"Some even grew more than one stone."
" After hundreds of millions of years of evolution, the original molluscs finally became a brand new species with sharp teeth."
"In the above story, growing teeth and growing hair. The two new traits are caused by genetic mutations. "
"The probability of their occurrence is the same. No one knows where molluscs will mutate and what new things they can mutate into."
"Therefore, there is no distinction between these two traits in the early stage."
"But natural selection, that is, famine, selected the variant with teeth to survive."
< br>“The teeth of living things play a vital role.”
“If the original famine turned into a severe cold, perhaps the mollusc that grew hair would have survived.”
"Because hair can retain heat better and resist severe cold."
"This is the true meaning of natural selection."
"Thousands of years ago, in our East, there was an old saying that expressed the meaning of closeness: Heaven and earth are unkind, and all things are treated as stupid dogs."
< br>“Gene mutation is the basis of natural selection.”
“Darwin’s theory of evolution, plus Mendel’s gene theory, plus my gene mutation hypothesis, become the perfect theory of evolution.”< br>
When Ridgway finished telling the story about the tooth.
There was an eerie silence in the venue.
Everyone was immersed in the story Li Qiwei told.
They never thought that someone could explain knowledge in such a simple and easy-to-understand way.
I am afraid that even children of a few years old can understand Li Qiwei's theory.
This ability is really terrifying.
No one could imagine how far Li Qiwei had studied the theory of evolution before he could explain it in such a simple and easy way.
But Pavlo was dumbfounded at this time.
He did not expect that someone could explain the theory of evolution from such a perspective.
This genius idea is as bright as the sun in the sky.
He couldn't imagine how Li Qiwei connected the theory of evolution and the theory of genes.
You know, he himself is also a professor of life sciences, and he knows both the theory of evolution and the theory of genes.
But Pavlo never thought of combining the two.
Not to mention innovating on this basis and proposing so-called genetic mutations, which is even more of a stroke of genius.
Pavlo thought that he would not be able to figure it out in a few lifetimes.
He couldn't help but sigh, is this the difference between gods and mortals?
If Li Qiwei knew what he was thinking, he would definitely comfort him: Brother, there is no need to belittle yourself.
Even Mendel, the founder of genetic theory, never thought of connecting it with the theory of evolution.
Mendel had a deep understanding of the theory of evolution.
So, there are too many unexpected things in the history of science. At this moment, Pavlo had completely given up.
He lost the courage to argue.
Li Qiwei's improved version of the theory of evolution has completely convinced him.
Pavlo is a professor after all, so naturally he will not mess around like a street quarrel.
In the face of such an impeccable theory, it would be a bit ridiculous to forcefully question it.
However, he was not downcast, but became energetic again.
Ridgway's theory allowed him to see the infinite possibilities of evolution.
For scientists, is there anything more worthy of happiness and celebration than another step toward perfecting a theory?
So, he said loudly: "Professor Bruce, what a wonderful speech."
"Your wild imagination conquered me."
" I gave in. ”
"I think you are already a top biologist."
"I have benefited a lot from today's debate, thank you!"
Boom!
As Pavlo admitted defeat, the atmosphere in the venue was instantly ignited.
The audience even whistled.
"Oh my God, Bruce is really awesome. He is a physicist and actually defeated a biologist. Is there anything more outrageous than this?"
"It's hard to imagine how he did it. Learning, can one person really learn so much knowledge at the same time?”
“Bruce is not only a biologist, but also a top biologist who improved the theory of evolution.”
“ I think the theory of evolution in the future will be divided into: Darwinian evolution and Bruce’s theory of evolution.”
This statement is agreed by many people.
Suddenly the crowd in the venue shouted: "Bruce's theory of evolution! Bruce's theory of evolution."
Ridgway smiled, this Pavlo was quite a character.
In this situation, the other party made the most correct choice.
I didn’t choose to be a cheat, but openly admitted my defeat.
This actually reflects his broadmindedness.
So Li Qiwei responded with his eyes to express his understanding.
The biologists at the venue, such as Bateson, Morgan and others, were all filled with emotion.
With just this battle, Bruce's status in the field of life sciences is almost on par with big guys like them.
It’s scary just thinking about it.
He is still the top physicist!
As for the big guys in other fields such as geology, forestry, psychology, and education, they all looked weird.
A different thought suddenly arose in their hearts.
“What would happen if Bruce entered our professional field?”
“Can he make any shocking remarks or publish any great results?”
大The guys' bodies suddenly trembled, so they decided not to do it. That was a bit sensational.
This is simply Leonardo da Vinci reborn.
If Li Qiwei knew what they were thinking, he would definitely say: Ask me quickly! Ask me quickly! In geology, I have the theory of continental drift, and in psychology, I have Maslow's hierarchy of needs theory.
Thomson looked at Li Qiwei with a look of relief, feeling happy for him.
He was not particularly shocked by Li Qiwei's theory.
This kind of simple conjecture and logical reasoning is a piece of cake for top physicists like them.
Thomson was confident that if he also studied the theory of evolution, he should be able to come up with similar ideas.
Should? perhaps? Maybe?
Lao Tang was a little unsure, because the sound of roaring mountains and tsunami at the scene made him shaken.
At this moment, Li Qiwei stood on the podium, enjoying the admiration and admiration of everyone.
A signature smile appeared on his lips.
Wilson complained silently: "Everyone, look out, this is the standard smile for showing off. You must learn it, and you can use it sooner or later."
Bateson, Morgan and others were extremely excited.
The celebrity effect is indeed extraordinary.
With Li Qiwei’s blessing, the name of genetics has become completely popular.
The content of today’s speech will definitely spread, and more people will pay attention to the development of genetics.
This is a very gratifying thing for industry leaders like them.
Moreover, after today, Li Qiwei and his improved theory of evolution will surely shock the world!
Originally, the debate should have ended here.
However, Bateson and others did not notice that Francis, who had been resting in the back, looked extremely bad at this moment.
His face is full of anger!
From the beginning, he was a little disappointed that he lost the debate.
Then, because of Li Qiwei's incident, he made a mistake and felt that he had lost face.
At the same time, I felt a little resentful toward Li Qiwei.
Then, Ridgway stole the show, and someone in the audience even shouted "Bruce's Theory of Evolution."
This made Francis completely intolerable and very angry.
His father Darwin is his pride, and the theory of evolution is the totem of their family.
He will not allow anyone to tarnish the theory of evolution!
Yes, in Francis's mind, he believed that statement tainted the theory of evolution.
He also blamed Li Qiwei for this anger.
"Bruce, you're just lucky."
"A man from the Qing Dynasty dares to replace the theory of evolution. Who do you think you are!"
At this moment, Francis was about to lose his mind.
Actually, all this was just his imagination, and no one had that kind of thought at all.
Darwin is still great, but Li Qiwei is even more outstanding.
No one would be foolish enough to disparage Darwin.
Francis has been basking in the glory of his father since he was a child.
No matter where he goes, he will be called "Darwin's child".
Over time, he believed that his father Darwin was the smartest man in the world and could not tolerate any slander.
And now, Li Qiwei even compared his father's reputation to that of his father, and he couldn't bear it anymore.
In addition, he is older and more stubborn as he gets older, and no one can persuade him.
He suddenly stood up and walked slowly to Li Qiwei's side.
Bateson and others thought he wanted to thank Li Qiwei in person for rescuing him, so they didn't think much about it.
Still discussing the future of genetics.
When Li Qiwei saw Francis coming, he was also very puzzled, not knowing what the other party was going to do.
Are you apologizing to yourself?
But there's something wrong with the other person's expression.
That expression was clearly looking at the enemy.
Under the puzzled gaze of Li Qiwei;
Under the indifferent gaze of Bateson and others;
Under the continued discussion in the audience;
Francis picked up the megaphone and said something he would regret for the rest of his life.
Thanks to the book friend [20222157] for the reward
