Genetic modification is a very controversial thing, and the moral and ethical issues involved are enough to deter anyone who wants to study it.

Even with an unwavering determination to study it, someone will still ask you: "If a person has modified his genes, can he still be called a person?"

Similar conflict of ideas and disputes are not uncommon in all kinds of science fiction works. At any time, there will always be a group of so-called human supremacists who clamor for a "purified world for the sake of blue" to jump out to stop it.

In order to prevent the so-called crime of "tainting human genes", they will even concoct more appalling and anti-human evils, and call it necessary sacrifice.

"...But, what can you really call a person? What is a person?" Chen Xin asked Qin Lan who asked the same question.

"Isn't a human being a human being? Human beings are human because we are smart, intelligent and thoughtful?" Qin Lan had seen some sci-fi works under the influence of Chen Xin before, but he was not sure about the question he asked. As for not answering.

However, this answer is obviously not comprehensive enough, at least not completely correct.

"The reason why people are human is indeed because we have wisdom and thoughts, but are wisdom and thoughts innate to human beings? The answer is not necessarily." At this time, Chen Xin really behaved like a scholar, sitting in front of Qin Lan Let’s talk about it: “If a baby grows up in human society, he will naturally have the wisdom and thinking that can be called a human being, but if a baby is far away from human society since childhood, or even raised by beasts. If he is too big, then he can't have the wisdom and thinking that a person should have anyway."

Qin Lan did not refute Chen Xin's statement, but nodded in agreement.

In 1920, in a small town called Midnapol in the northeast of Kolkata, India, two girls who were raised by wolves and called wolf children were found and caused a sensation.

The eldest of the two girls is about seven or eight years old, and the youngest is about two years old. The two little girls were sent to the orphanage in Midnapole to be raised, and they were named Kamala. , the little one is called Amala. By the following year Amala died, while Kamala lived until 1929.

Through this incident, it was concluded that if the wolf child was not born with a congenital defect, then this case shows that human knowledge and talent are not innate, and upright walking and speech are not innate instincts, All of these are the products of acquired social practice and labor.

"So the reason why people can be called people and possess wisdom and ideas is because of the existence of the entire human civilization and society. If we lose these, we are not much different from beasts." In Chen Xin's view, people The reason why it is called human comes from the mind and the soul, not the body: "If it is purely from the point of view of species, human beings are also Homo sapiens, only one of the species under the suborder of the order Mammalia.

Even under the genus Homo sapiens, there are 16 other species in the same row as Homo sapiens. Although they are extinct, they can also be called humans from a biological point of view.

Therefore, purely from the perspective of biological classification, there is no essential difference between humans and other animals. The so-called human supremacy is just the arrogance of human beings. "

"But even if there is no essential difference between humans and animals, humans are also a type of animals. Isn't genetic modification still polluting the purity of human genes?" Mo Qingyan, who appeared on the side at an unknown time, suddenly interjected. : "And aside from other issues, Ah Xin, you used wolf genes to transform human beings. Is it a wolf or a human? Don't do this kind of thing that goes against morality and ethics? Didn't the country come out before the disaster? Is it an illegal gene editing crime? Ah Xin, your practice is already illegal, right?"

"That's a newly added provision in Article 336 of the Criminal Law. It is a crime to implant a gene-edited or cloned human embryo into a human body or animal, or implant a gene-edited or cloned animal embryo into a human body. "Because of the relevant genetic modification research, of course, Chen Xin also checked the relevant legal provisions: "Embryos implantation is a crime, and it is not illegal to study genes alone."

"But even if it's not illegal, it's also against morality! Human genes are the perfect product of evolution, how can they be modified at will?" Because of his former professional habits, Qin Lan didn't like Chen Xin's legal provisions. I can do it without a regulation. attitude to do.

"Morality does need to be followed, but if there is ignorance and ignorance in morality itself, do we still need to follow social morality? In the feudal era, women's incompetence was morality. This was the social morality at that time, but we still need to abide by this kind of thing now. Is it? Society is constantly developing and progressing, and so is morality." Chen Xin explained to Qin Lan and Mo Qingyan painstakingly, trying to convince them both.

This is just the two of them. If it was someone else, Chen Xin would have been impatient long ago. How could he have such good patience to explain slowly.

"Even if social morality needs continuous progress and development, this is not a reason to modify human genes at will, right?" Mo Qingyan comforted Qin Lan, who was a little excited, and turned to Chen Xin and asked: "The human body is a natural evolution. The perfect masterpiece, even if there is something inappropriate, can't it wait for human self-evolution? Why do you have to use such a radical method of genetic modification?"

"The human body is perfect? ​​Hahaha, Long Niang, you are afraid that you have read too many novels. Do you really think that human beings are innate Dao body, and monsters must first become human in order to cultivate?" Chen Xin seemed to laugh when he heard this. His stomach hurt, until Mo Qingyan pinched him in dissatisfaction, he put away his smile and continued to explain: "The reason why humans are like this is just the result of constant compromise with the natural environment, because the evolution of human beings It is not the body, but the brain. From the perspective of biological evolution, the human body is actually very cumbersome and bloated.

And it's not just our body, even our genes are the same. There are countless redundant chains in our genes. Some of them come from the remnants of our past evolution from the ocean to the land, and some are just to adapt to certain The emergency mechanism evolved from the environment of a special period, but these things are all retained in our genes, redundant and useless.

It doesn't matter if it's just the excess garbage, but these complex and complicated genes are mutating all the time, and even self-collapse, forming life-threatening tumors in the body.

To remove the sanctity of human beings, simply from the perspective of the strength and weakness of the biological structure and the pros and cons, all the organs of human beings are not the best, and even many of them are outrageous.

Overlapping organ functions, enormously wasted nerve conduits, blood vessels and neural networks that are entangled like the most complicated maze but not as straight as a straight line, and all kinds of discarded and useless information that exists from the beginning of genes...

If human beings are regarded as an engineering creation, then this creation is completely a substandard product that can continue to work through various coincidences and constant beating and making up of external factors.

Therefore, with the development of human science and technology and the progress of medicine and biology, the optimization of genes and genetic modification are inevitable for the development of science and technology. "

The reason why a person is a person really has nothing to do with genes and the body. The reason why you are an individual is because you have a mind, not simply from a biological classification you are an individual.

As a single species, human beings are neither holy nor great. They are just the lucky ones who have embarked on the route of evolutionary nerves and brains in the process of biological purification. There are even others who have taken this route at the same time. Sixteen human races, but they were all wiped out.

Human genes also have too much useless information. For example, people have tails during embryonic periods, and the tails will disappear as you grow. These are actually the remnants of biological evolution.
