Why is there some bad survival of the fittest in genes that have not been eliminated?

At present, the concept of beauty and ugliness of the human face only increases sexual attraction, and has no impact or significance on the direction of survival outside human society.

Since it is about sexual attraction, can we compare the face to organs such as the chest, buttocks, legs, etc., at a certain time? If you can, then beauty and ugliness are just individual differences like every physical sign. If it's individual differences, which one do you use as the standard for the 60 billion individuals in the world?

Are the rest of the people all ugly? Is it to eliminate these 60 billions of ugliness? Or do you want to eliminate this standard and change it to a new one?

Because beauty and ugliness are relative standards, yes, ugly people are a lot of people who have died.

The problem is that after the ugly man dies, there is another beauty and ugliness in the beauty. <>

Transformation of good and bad conditions.

First of all, you can ask the above question, you may not know too much about the reason for genetics, the so-called survival of the fittest is actually mainly about the survival of the fittest, that is, we continue to adapt to the living conditions at the same time, and gradually adapt to the current living environment, at the same time, our so-called beauty and ugliness is also a relative concept, that is to say, there is no absolute beauty and ugliness, if there is no ugliness as a comparison, then you can't tell what is beautiful, right?

The second is that our human standards for beauty are also fundamentally different with different people, different regions and different cultures, that is to say, you think beautiful, others do not necessarily think so, Chinese think beautiful, foreigners do not necessarily think beautiful, so for this uncertain characteristic, human beings will not deliberately choose to change and adapt to him, so to some extent, the survival of the fittest in genes can not change this relative standard.

Again, although the gene has the characteristics of survival of the fittest, but the genes of human appearance also have very uncertain factors, and now many people think that they look very average, but he is very good in other aspects, for example, not looking good does not affect the other party to become an excellent scholar, an excellent businessman, and even many excellent actors The appearance is also very ordinary and can even be said to be not good-looking, so in this case, maybe the other party looks very average but is very good, and he can get a wife, On the contrary, even if you are very beautiful, but you are just beautiful and nothing else, you are also a single dog, so excellent genes do not necessarily appear in appearance, IQ, EQ, and many other aspects are also part of excellence, right?

In the end, it is still that sentence, the beauty and ugliness of human beings are relative, how can you distinguish what beauty is without the so-called ugly? Do you think they are beautiful with plastic surgery all over the streets?

In this world, there are beautiful, ugly, fat, and thin, which is actually the reason for biodiversity, although genes have the characteristics of survival of the fittest, but there is no way to completely eliminate all ugly people, no matter how you eliminate, you will always find a less beautiful person in this part of the people, so no matter how you eliminate it, it is impossible to reach the same standard. <>

First, only for genes, not for appearance

I have also thought about such a question before, why everyone in this world is different, whether it is a boy or a girl, everyone seems to have their own unique characteristics, some people say that genes have the characteristics of survival of the fittest, and everyone who is born is very good. I want to say, it is true, genes are the characteristics of survival of the fittest, but survival of the fittest is only for genes, and it is not possible to guarantee that everyone is beautiful, whether you are beautiful or not is related to your parents' genes, and biodiversity is also the primary characteristic of genes. <>

Second, whether you look beautiful or not is also related to the environment in which you grew up and lived

Everyone looks the same beautiful, and has no features at all, and this kind of beauty is actually the same, but has no characteristics. And you must know that genes do not have the ability to judge beauty and ugliness, it has no way to intervene artificially, and it is impossible to achieve the desired effect. Whether you are beautiful or not is also related to your growth environment and the changes of the times, what your family is like, you are what you are, if you really want to change, you have to start from the source to change.

Different regions, different countries, each person's characteristics are different, and everyone's changes are different, although the gene has the characteristics of survival of the fittest, but in such a complex situation, he has no way to eliminate those ugly people. When I saw this topic, the first thing that came to mind was that this question was meaningless, we just need to know that everyone who was born was the first place of excellence at that time, and they went through layers of elimination before they finally became such a person.

Because ugliness is everyone's representative, ugliness has nothing to do with genes, although ugly but as long as the body is healthy, there is no problem with genes, so ugly people have not been completely eliminated.

Because this is caused by genes, in fact, there are beautiful and ugly people in the world, there are fat and thin people, which is also relatively normal, which is due to the diversity of organisms.

Because ugliness does not affect survival, a wise person or a person with economic strength will have descendants.

The remaining half can also be divided into beauty and ugliness, and if you keep eliminating the ugly, the remaining half will still be ugly. From the perspective of the mathematical model, there are always ugly people, plus time relations, in addition to mutations and deformities, etc., people are more beautiful than primitive people, so the main problem logic of this topic should be a fundamental problem in biology, but it is actually a sociological and psychological problem 1: The condition for choosing a mate in ancient times is not to look at beauty and ugliness, that is to say, the logical premise of the topic does not exist!

<>In modern society, some countries have begun to choose free love, and appearance is only a condition for choosing a mate, not the most important condition! Therefore, the logic of the question is difficult to meet the premise! Three:

Even since ancient times, mate selection is only a condition of appearance, so all appearances in human society are evenly distributed, that is to say, according to monogamy, ugly people and beautiful people can find objects, so the logical premise of this problem still does not exist! In fact, there is a premise for evolutionary selection, the most important premise is survivability, and if you have strong survivability, it is easy to obtain the right to mate, but the survivability of human society is not completely related to appearance, and appearance is only one of the most important factors! So, in human society, appearance is the most important.

All things are relative, two sides of the same coin. There is no absolute good, and there is no absolute bad. At the time of evolution, the concept of genes had not yet been formed.

It was not until later that the genetics of genes was gradually incorporated into the theory of evolution. Therefore, it can be said that this question is a false proposition. There are no genes for survival of the fittest, and some are genetic mutations.

Mutations may give rise to a new species or subspecies of that species.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

There are all kinds of people in the world, and genes are inherited through parents, although it is said that some ugly people will be eliminated, but not all of them will be eliminated, so there are still ugly people in the world.

This is also for the sake of people's future generations, so the genes of ugly people still have room to survive, and there is no limiting factor for ugliness, they can still do a lot of meaningful things.

It is because there are many ugly people, and the metabolism of genes is very slow, so in the process of development for such a long time, not all of them have been eliminated.

I guess that there is no way to eliminate it, because as long as it is a woman, regardless of whether her appearance is in line with a man's aesthetics, you can find a man. But men can't do it, it's too ugly for a daughter-in-law to be a daughter-in-law. In this way, the general appearance does not conform to the woman's aesthetics may be eliminated, but if the man is diligent and earns money to support the family, he can also be a daughter-in-law, and the eliminated is also the kind of life that cannot take care of himself, but women are generally not eliminated, but the life can not take care of themselves is enough, because the appearance of women has everything, so, of course, the offspring, of course, will not be all the same.

This is actually a blessing from God. Otherwise, after elimination, due to the consistency of aesthetics, people all over the world will slowly grow into the same. When I looked back, I saw that I looked the same as myself, like a zebra, an antelope, a striped, scary, like a clone.

Therefore, this beauty and ugliness exist, it is God's blessing, there is no need to dislike others for being ugly, and there is no need to be jealous of others' beauty, God has his own good intentions.

First of all, beauty and ugliness are very subjective and have never been a fixed number.

For example, the Tang Dynasty was fat for beauty, and now it is.
