I saw Tuanque clearing his throat, picking up the pointer and tapping the blackboard:
"Today is the first class of school. I won't teach you any professional knowledge. I will tell you what human race is!"
As he spoke, Tuanque wrote the word "human race" on the blackboard, and the classroom suddenly became quiet...
Tuanque continued: "Does anyone know how long the history of the human race is?"
Lu Chen immediately replied: "According to ancient records, human civilization can be traced back to about five thousand years~"
"According to the theory of evolution, about 4.5 million years ago, apes began to differentiate. Humans could walk upright. Two million years ago, the brain evolved for the first time. It was completely different from apes and could make simple tools and use them. Fire, and seven to one hundred thousand years ago, the brain underwent another evolution, and wisdom was improved, gradually forming the human race today..."
After speaking, he proudly raised his eyebrows at Ren Jie.
Tuanque said calmly: "What Lu Chen said is indeed true. These are the knowledge in books, the history that the ancestors tried to dig out. Archeology is simply the process of tracing back to the source and finding the truth, but the history and truth of the human race are really Is it like what the book says?"
"I'm telling you, maybe it's not..."
As soon as these words came out, the students were all stunned, weren't they? What else could that be like?
Tuanque squinted:
"The era of genes has begun. Senior Yang Hongxiu deciphered the genetic sequence of the human race and developed a spiritual gene potion. The genetic sequence of the human race also allows us to truly understand ourselves."
"Human genes are too complex and diverse, far beyond any life form on the Blue Star. What we show is only a very small part, and this is not all of us."
"And...why among all the species on Blue Star, only humans have gene locks? They are even engraved in the genes. Gene locks are by no means naturally formed, let alone the result of evolution."
"It's only 4.5 million years. It's just a blink of an eye in the entire evolutionary process. Even counting from the first living cell, such a long time is not enough for humans to have such a large and diverse set of genes. library."
Ren Jie was stunned:
"What...what do you mean? Are you saying that humans have existed on the Blue Star for much longer than 4.5 million years?"
This definitely subverts the views of all students.
Tuanque did not directly answer Ren Jie's question, but continued:
"Do you really understand the genetic sequence of the human race? There is a gene in our genetic sequence. Researchers don't know the meaning of this gene, so they call it a useless gene."
"But later research showed that this gene came from a virus in early ancient times, a virus that ravaged all mankind. This virus may have lasted for tens of thousands of years, but humans were not defeated by the virus. It’s crazy adaptation, producing antibodies to fight the virus.”
"In the battle that lasted for tens of thousands of years, humans defeated the virus, but they also left behind a small piece of genetic sequence in their own genetic sequence to prevent similar situations from happening again in the future."
"Every one of us humans has this gene, and those who didn't make it through will die. This small gene records the history of struggle that lasted tens of thousands of years. It is evidence that humans have tried their best to survive. It’s even engraved into the DNA.”
At this moment, all the students were listening silently. They had already guessed what Tuanque wanted to say.
Tuan Que narrowed his eyes and said:
"So...where did our species come from with such diverse ability genes? Why do they appear in our genetic sequence and exist in a recessive way?"
"What does their existence indicate? And what are they waiting for?"
Jiang Jiuli opened his mouth wide:
"Teacher Tuanque! Are you saying that all human ability genes are actually the result of human beings adapting to the difficult environment?"
"This, this, this...heaven..."
Tuanque nodded heavily: "This theory is currently speculation among scholars. There is no direct evidence that all ability genes originate from this."
"But evolution is originally a matter of removing the dross and extracting the essence. Useless things will be discarded during the evolution process, and only the useful things will be preserved over time."
"But our human race retains so many ability genes."
Having said this, Tuan Que raised a smile on his lips: "We might as well make a bold guess that spiritual energy has revived in history, or that humans have embarked on a journey of cultivation more than once, and each time the power system and civilization of the times are different!"
"Take the fire ability in the ancient bloodline as an example. In the endless past, the human race may have started an era of cultivation that focused on cultivating fire. All the people cultivated fire. Over the long years, the ability of fire was burned into the genes of the human race little by little. In the sequence, with inheritance, it is passed down from generation to generation until today."
"And only in this way can we explain why it takes time to engrave the gene fragments with fire abilities in the human genetic sequence into DNA."
Lu Chen's scalp was numb: "How is this possible? Are you saying that every ability contained in the human genetic sequence may be the result of human beings starting one era after another in ancient times?"
"You must know that there are more than 30,000 recorded abilities of human beings. Each ability requires an era of national cultivation before it can be burned into the genetic sequence. On average, an era lasts tens of thousands of years."
"So how long will the history of the human race be? This... this is not scientific!"
Tuanque smiled: "The suspicion is right, but...is it really unscientific? Does what you know must be the truth? The history of Blue Star is much longer than you think."
"We have discovered broken ruins in the mantle layer, buried battlefields in the strata hundreds of millions of years ago, giant towers engraved with runes in volcanoes, and even in ocean trenches more than 10,000 meters deep. Heritage buildings.”
"Before the cataclysm, why did humans spend huge amounts of energy and financial resources to colonize the moon and explore alien planets? Because there are ancient ruins even on the moon."
"Perhaps the footsteps of the human race have also reached the sea of stars and the vast Milky Way."
All the students had numb scalps and stared blankly at the birds. This first lesson of the semester was undoubtedly shocking to everyone.
Ren Jie swallowed:
"Then... why doesn't the book say this?"
Tuanque spread his hands: "Because it's impossible to be sure. The only thing that can be certain is that the history of the human race is definitely more than five thousand years."
"Because everything recorded in the human race's genetic sequence is the thick history book of the human race, the history of the struggle of countless human race ancestors. It is precisely because countless ancestors, generations of human beings, have added bricks and tiles to the human race's genetic sequence and painted a new chapter. The rich and colorful strokes of pen after stroke have led to the diverse genetic sequence we have today."
"And this is the history of the human race, and it is also the heritage of the human race! We are standing on the shoulders of countless ancestors, looking at the stars and the sea!"
After listening to what Tuanque said, the students' eyes were filled with light and goosebumps shot up to the sky.
Tuan Que continued:
"Perhaps... human civilization has experienced more than one catastrophe and been destroyed more than once. We have lost our own history and do not understand our past..."
"But the fact that we still exist today is enough to illustrate the problem. Human civilization is like a fire that never burns. No matter how many times it is extinguished, the remaining sparks in the fire will support us to stand up again from the ruins. , burn again!”
"Human civilization has never been extinguished, and now we are standing at a juncture in history!"
"Perhaps it is no longer important to trace where we come from, but we must know where we are going, if we still don't know..."
"Then when the moon is full and the stars are shining, raise your head and look at the sky that never turns dark!"
