Will the development of medicine lead to the degradation of the human race?

The law of survival of the fittest is for the entire population of the species. In general, the strong have a better chance of reproducing and passing on their strong genes, and as a weak person, of course, there is also the possibility of continuing the offspring, but it will eventually be eliminated.

Your idea is far-reaching, and it is against natural selection, but.

1。You have to admit that this is a people-oriented society;

2。Isn't the hot genetic engineering that has been studied in recent decades just to modify the bad genes of human beings?

This question is very good and timely. I won't say it first; [The current progress of medicine has led to more and more infirm people and people with congenital diseases surviving], only to say that many people currently think that young, healthy-looking people, people who have nothing wrong with the hospital examination. If you have a bad face, it means that there is a problem with the internal organs.

Acne indicates that there is a problem with the internal organs, the hunchback collapses indicates that there is a problem with the internal organs, and affects the spine, obesity is a manifestation of internal organ problems, myopia is also, now the hospital can not detect it, pancreatic problems, accounting for 60-80% of the population, so many real problems, people have not thought that this is a big problem, if these people are getting married and having children, there are many problems passed on to the next generation, it is inevitable.

Modern people are taller than ancient people and have a stronger physique than ancient people.

Modern people think faster than ancient people, and they don't think as much as ancient people.

Humanity will not perish unless there is force majeure.

Yes. On the one hand, the development of medicine will allow human beings to live longer. Perhaps a few hundred years of human fantasy can be realized, and the current laws of human beings will be completely changed; On the other hand, the development of medicine can also change people's bodily functions and genes.

Perhaps the race in future sci-fi blockbusters may also appear.

I think it's related. Because of this, we humans are even more unable to adapt to the harsh environment.

According to the definition of evolution, it is difficult to say whether changes in the gene pool have become faster or slower under these two opposing influences......Modern medicine itself has only existed for a long time. It is not enough to cause dramatic changes in the human gene pool, so comparisons cannot be made.

At the same time, it should be clear that evolution is only a means for organisms to survive and pass on their natural genes, and not an end ......Because humanity is significantly less costly and efficient in fighting pathogens or other pathogens than evolutionary, developing a more important factor in modern medicine, why should we pursue evolutionary means?

It is important that there is a consensus in the academic community that there is a significant positive correlation between population and the rate of human development. It's actually quite easy to understand. A small group of people can contribute to human development, while people who are technologically advanced are a small part or all of them.

When other factors, such as the level of education, remain constant, the more pronounced the population and the more people can contribute, the faster technological progress is bound to be.

As a result, ancient China was one of the most progressive countries (as it was the most populous country in ancient times......while the level of education, economic conditions and other factors in ancient times were basically the same), and the number of people who could benefit from technological progress through international exchanges increased considerably, and technological exchanges themselves contributed to technological progress (so it is clear that the technological progress of a closed country or similar state policy usually slows down the country's technological progress considerably).

Therefore, it can be unequivocally said that modern medicine has indirectly contributed greatly to the technological progress of mankind in reducing the mortality rate of the population. Even if modern medicine does actually hinder evolution, its positive effects far outweigh the negative effects of hindering evolution.

There are some reasons for this, after all, this has reduced human exploration.

I don't think the two have anything to do with each other, but the development of medicine is progressive.

There is no hindrance between the two, on the contrary, there is a driving effect.

According to the "normal" path of evolution, there will always be some people who are resistant to this bacterium, and then when it happens, these people have a very obvious survival advantage, and it is easier to pass on the genes to future generations.

Of course, bacteria also evolve, and humans and bacteria are in this evolutionary competition. If humans can't get rid of bacteria, it's not impossible that the whole will be "wiped out". In the history of life on Earth, there are many examples of entire populations being "passed" by natural selection, and there is nothing special about human beings.

Modern medicine will not only change the normal evolution of human beings, but also the normal evolution of other living things, such as the misuse of antibiotics, which leads to the "accelerated" evolution of bacteria into superbugs. At present, in this life-and-death competition, the only remaining ** human race is the power of science and technology. If you want to rely on "normal" evolution to deal with superbugs, you will have to pay the price of a large number of lives.

The smallpox virus, for example, has killed at least hundreds of millions of people in human history. If "normal" evolution continues, this competition between human immunity and viruses could continue for hundreds of thousands of years, killing tens of billions of people. But on October 25, 1979, the WHO declared smallpox eradicated, and humanity completely defeated smallpox.

This is an excellent example of modern medicine altering "normal" evolution.

The process of biological evolution, including the process of human evolution, follows a natural law, which is essentially the process of changing the gene frequency of a population. The direction of this change in gene frequencies is determined by natural selection. So the development of medicine will have an impact on human evolution.

Because human beings are slowly evolving, the task of medicine will gradually shift from the prevention and treatment of diseases to the maintenance and enhancement of health and the improvement of people's quality of life In the future, it will no longer be just patients who seek medical services, but a considerable number of normal people.

After the development of modern medicine, human beings have used various medical means and mobilized the forces of the whole society to strictly prevent and control possible epidemics and actively isolate them. Therefore, whether it is SARS, avian flu, or Ebola, it has not caused a large-scale outbreak, which should be regarded as the "normal" evolution of human beings affected by modern medicine.

Modern medical methods have solved one after another problems and even disasters encountered by human beings in the process of natural selection in the past, so modern medical methods have saved human beings from some diseases, and at the same time, they will also slow down the evolution process of natural selection for human beings. Then someone must ask, what is the effect on human genes? As a simple example, if someone becomes pregnant after AIDS, will it be passed on to the next generation?

That will definitely happen, so it can be seen that while medical methods are benefiting mankind, they are also slowing down the process of human evolution, or even changing! <>

The obstacles were mentioned in the answers of the others. As another example, medicine may well have hindered the further evolution of the appendix – that is, its complete disappearance. Before the advent of modern medicine, acute appendicitis was almost an "incurable disease".

People with an excessively large appendix have a high chance of dying from acute appendicitis. But now we probably haven't heard of anyone around us who died of appendicitis, right?

It makes sense to say that there is no obstacle. Since human beings have entered the civilized society and lived together at a high density, life and death are no longer simply health problems. Sociologist research (rigorous research with detailed data) shows that the environment in which we live largely determines our future, including life expectancy and the survival of future generations.

One might object to this view and cite counter-examples. Personally, it is possible to have different lives and break through the so-called destiny, but as a whole, statistics do not lie.

On this basis, the social living environment is still effectively screening human genes, which cannot be changed by the improvement of medical standards. From this point of view, humanity is still evolving.
