Almost all people who study biology have done experiments with animals.

The most famous is naturally the guinea pig.

If we think about this question from the perspective of the philosophy of life, every kind of life created by Nuwa or other creators must have a reason for its existence in this world.

All animals, such as mice and frogs, that are always available in the laboratory, should have their own natural journey.

Of course...... It is also a natural process for human beings to use all means to improve themselves, and it is also a necessary step in the evolution of human life.

It's just that when human beings do this, they don't think about why they want to base their human progress on the use of other life.

It is said that human beings are the most cruel in this world, which is really true, after all, human beings can even use their own kind of terrifying life to experiment under certain circumstances.

However, all this is because human beings have the power of life and death in the entire biological world!

Any creature that gains dominance in the constant struggle of all things in the world will be as brutal and terrifying as humans.

The supremacy of life and the equality of all things is just a view of the supremacy of morality, which is called the law of nature, and on a large scale, it is the law of the jungle.

As the old saying goes, people don't kill the heavens and the earth for themselves.

This seems to be a very selfish sentence, but it shows a very clear fact, if it is natural selection, the survival of the fittest.

At this point, it makes no sense to extend morality to other species. If people are locked up with beasts with their bare hands, the beasts will eat because they need to survive, and humans will rebel because they survive.

When humans did not evolve to what they are today, countless ancestors were reduced to one of the animal food chains.

Finally climbed to the top, how can you not firmly grasp your own rule.

Of course, the creatures at the top of the food chain will die sooner or later.

For Ye Xuefu, the first time she did animal experiments, she also felt very cruel, and she didn't even dare to start.

But think about the text "We Must Fight for Strength" in the Chinese textbook when I was a child, which talks about two things that Mr. Tong studied diligently and studied hard for the sake of the motherland.

There is a clip in it that has a deep impact on Ye Xuefu.

It's said that there was a professor who had been doing an experiment where he had to peel off the outer membrane of a frog's egg.

This type of surgery is very difficult to do, and it requires skill, patience and care.

This professor has been doing it himself for several years without success, and none of the students dare to try.

But Mr. Tong studied hard quietly, he was not afraid of failure, he did it over and over again, and finally succeeded......

Ye Xuefu's first experiment was not to strip the outer membrane of the frog's eggs, but to destroy the frog's brain marrow...... When she first grabbed the frog, she was in a daze, and it is no exaggeration to say that her mind was really blank and there was nothing!

She is an excellent high-achieving student, and she faced such an unacceptable experiment for the first time, and in the end, Ye Xuefu still couldn't start, and finally asked a classmate to help her solve it.

For the next two days, Ye Xuefu was in a trance, and she began to wonder why she wanted to study this major and why she did these things.

At that time, she also fell into a "misunderstanding" that life should be equal, of course, it can't be said to be a misunderstanding, but she began to doubt her decision.

Later, under the guidance of her teacher, she finally figured out why she chose this major, because she is a member of the human race, she wants to study for the progress of mankind, and everything she does must reflect her values.

If she can't be a useful person to society, then life will have no meaning.

Later, Ye Xuefu asked the teacher why she had to destroy the frog's brain marrow first, she felt that this was still a little difficult for her to accept, and the teacher replied that it was to make the frog less struggling and facilitate the operation of all the subsequent experiments.

In order to make Ye Xuefu feel relieved, the teacher said that this can reduce the pain of the frog, so that its nervous system does not perceive, and the frog will not be so painful.

This relatively humane answer made Ye Xuefu feel a lot more relieved.

Later, when Ye Xuefu used rabbits for experiments, she would first use anesthetics on the rabbits, and when the experiment was over and the anesthetics disappeared, she would use air needles to directly kill the rabbits.

Slowly, Ye Xuefu no longer hesitated, because she knew that the neater the movements, the less pain the animal would have.

Every time, Ye Xuefu felt very uncomfortable.

And there will always be people who stand on the moral high ground and accuse them of cruelty to animals, saying that her pain and discomfort are a kind of hypocrisy!

Ye Xuefu has never refuted it, because she really can't find a complete alternative to animal experiments, people will never be able to experiment on living people, and the guy in Dongying's army who only uses live people for experiments is not human at all.

Now that Ye Xuefu is fully mature, she will not feel guilty and blame herself for this, she has realized that cruelty is originally part of the natural world.

Isn't it cruel to the treatment of animals when humans eat meat? Even if they don't eat meat, they have to replace them with vegetarian food, and there will be plant protectors who stand up and shout that plants are also life, and all lives are equal.

If this is the case, everything on the planet that cannot survive by photosynthesis will starve to death.

Too many of the Virgin will stand in the perspective of the Virgin Mary and enjoy the health and safety brought to them by medical and biological research, and criticize the cruelty and ruthlessness of medical and biological research, which is simply a very irrational and vexatious joke.

Of course, if all the sentences for criminal humans were changed to experiments on living people in the future, perhaps the crime rate in this world would be reduced a lot.

For small crimes, do some small experiments, at most a little bit of vomiting and diarrhea adverse reactions, and for larger crimes, do a little bigger experiments, and if you really have a sequelae, you deserve it, and if you seriously murder, abduction, trafficking, strong X, corruption, etc., you can directly use it to do the test and die...... Come on, that's a humanitarian issue again.

To put it bluntly, biological research experiments are a kind of saving small evils with great good.

After all, today's society is a human society, so everything should be based on the interests of human beings, and even if other small animals are used in the experiment, criminals will not be used, because they are lucky to approve a "human skin".

What Ye Xuefu can't accept now is those crazy people who are experimenting with other lives.

Those madmen don't care what the test object in their hands is, whether it is a human or other animal, as long as it is a creature that can let those madmen get the results of the test, those madmen dare to use it!

It is because of the existence of those crazy people that so many strange creatures of all shapes* appeared.

Those things are often created by human beings themselves, and sooner or later human beings will kill themselves and die at the hands of those who have created themselves.

The process of life is a process of choice, and the understanding of ethics is also a process of choice.

There is a thing in this world that absolutely does not exist, that is, a perfect thing, and all ideas that try to lead mankind to perfection will eventually lead mankind to a devastating disaster.
