Human beings originate from the same ancestor, why do some people get uglier and some people become

Evolution is the concept of a group, only the population is the basis of evolution, so human beings do not have only one ancestor, but a large number of Australopithecus have evolved into modern humans through the stages of Homo sapiens, Homo erectus, Homo sapiens, etc., due to the different environments experienced in the evolutionary process, people in different regions have certain differences in appearance, mainly blood group distribution, skin color, eyes, ears, mouth and nose, body hair and other external traits. There will also be some changes in appearance at different stages of a person's development, and the secretion of hormones can change a person's skin color, skin volume, hair quality and other characteristics, which may make people more and more beautiful or ugly. However, in general, the physiognomy will not change too significantly.

There are many factors that affect appearance, such as their own maintenance and excellent genes from their parents. If the father and mother are good-looking, then their children will naturally not be bad.

The evolution of human beings is natural selection, the survival of the fittest. In the process of human growth, there is the inheritance and mutation of genes, which are affected by the environment and their own physique in the process, and people's aesthetics are not the same, so in the process of existence and development, high-quality genes will continue more and more. But in the process of human growth, the secretions in the human body are constantly changing, which also affects people's beauty and ugliness.

First of all, the basis of evolution is population, so humans do not have only one ancestor; Secondly, a person's appearance will tend to stabilize after maturity, and will only slowly age, and will not become beautiful or ugly.

Beauty and ugliness depend more on the spiritual level, and people in a generally healthy, optimistic, joyful, and happy state are the most beautiful. And these can be your personal choices, and you can never refuse something beautiful.

Not to mention human ancestors, even if there is a person with a hairy face, we will also feel bad. The physical characteristics of human beings are constantly changing in the process of evolution, and humans who are accustomed to seeing modern faces naturally do not look down on the appearance of apes like their ancestors.

There is no specific standard for beauty and ugliness, only a general indication, both are abstract meanings, and human beings who can describe a person in concise words are already human beings who have entered a civilized society, so in ancient or modern times, men like beautiful women, and women like handsome men. However, in the distant primitive times, the most important thing for human beings was to eat, drink, Lazar and reproduce, and because of the barrenness of materials, human beings were not in the mood to consider beauty and ugliness, and there was a lack of toiletries. Isn't that beautiful?

Probably even if the appearance meets personal standards, most people will not like it at first sight.

The appearance characteristics of human beings have been changing in the process of evolution, human beings were born from Australopithecus, the initial facial features are still a bit like apes, the upper and lower jaw structure makes the mouth and chin protrude, the structure of the skull makes the eye sockets relatively deep, and human body hair has also gone through a considerable period of time, and people who are full of hair do not conform to the aesthetics of modern people.

The change of human image is affected by a variety of factors, the structure of the upper and lower jaws is related to the food that humans eat, at first eat fruit and eat raw meat, and later will use fire to eat cooked meat, cooked meat needs less force to bite, gradually human masseter muscles gradually weakened, expression muscles are more and more abundant, human beings have the most abundant expressions of animals in nature; Upright walking brings changes in the lower abdomen and lower limbs, the structure of the lower abdomen is related to the pelvis, upright walking changes the shape of the pelvis, and the muscle and bone structure of the lower limbs are gradually more suitable for upright walking.

The volume of the abdomen has also changed, the original apes ate more vegetarian foods, plant foods are rich in fiber, and if you want to digest it, you need a larger large intestine with stronger capacity and muscles, so the stomach and intestine volume of apes is larger, while modern people are omnivorous, the large intestine is not very long, and the small intestine is not very long, relatively speaking, it is in the middle of herbivores and carnivores; The size of the brain gradually increased, and the back of the head became larger and larger, becoming what it is now; Body hair gradually decreases, from being covered with hair all over the body to only having coarse hairs in some key areas.

These changes are not due to the fact that human beings use more or use less, but the environment in which human beings live has undergone great changes, and the appearance of human beings in a long history has finally evolved into modern human beings.

I don't think they're ugly, it's because we're so pretty.

Because the ancestors of human beings have not yet fully evolved, like humans and monkeys, they look particularly ugly.

During the primitive society, due to low productivity, people lived in groups, and were threatened by wild beasts.

Bigger is beautiful. At the same time, because of the pursuit of reproduction of the next generation, women are good at giving birth to beauty.

Extended Knowledge:

Beauty is the product of human social practice, the manifestation of human active life, and the pleasant emotion caused by objective things in people's minds. Aesthetics sees the world from an aesthetic perspective and is an integral part of the worldview.

Aesthetics are formed in the social practice of human beings, and are closely related to other ideologies such as politics and morality.

People from different eras, different cultures, and different social groups have different aesthetics.

Aesthetics has the characteristics of the times, the nation, and the commonality of mankind, and has a class character in a class society.

Human progress has nothing to do with heredity, so the proportion of good and ugly has nothing to do with it.

In the final analysis, human evolution is a change in adaptability, not a change in appearance, and heredity may not necessarily develop for the better, so the imbalance between good and ugly cannot be compared. The evolution of human beings lies in the evolution of the mind, and the changes in the adaptability of the brain and body have nothing to do with heredity; Heredity is random, one side of the gene is strong and the other side will be biased, and the uncontrollable gene cannot be compared with human evolution.

Human evolution is to survive more conveniently, not to say for aesthetics, people's current aesthetics are also different, some people think that a person is good-looking, some people think that this person is not good-looking, so it is difficult to reconcile, he can't be completely beautiful, if they are all beautiful, they can't stand out, who is beautiful everyone is the same, just like robots, there is no difference between beauty and ugliness, because there must be a part of people who can set off it, and some people can have the difference between beauty and ugliness, just sunlight and darkness, There is beauty and ugliness, there is goodness and sin.

No matter how many years of human evolution people's appearance is still the same as now, each has its own characteristics, everyone's aesthetics are different, so the view of beauty will be different, not that it is ugly and beautiful, but the facial features are less delicate, and whether it is ugly or handsome, there will be people who appreciate his beauty!

I think everyone's vision is different, and I think that after so many years of human evolution, there are still more beautiful people. Because everyone's vision is different, and then you look at someone else as ugly, then you think he is ugly, if you look at him beautiful, then you think he is beautiful, and this is judged according to your own vision.

I think the beauty and ugliness of people have nothing to do with the evolution of human beings for so many years, most of the appearance of human beings is related to their family genes, a child is born more or less with the appearance of parents or both sides, besides, everyone's appreciation level and aesthetics are different, and the beauty of the heart is more worthy of attention than the beauty of the appearance.

I don't think it's a matter of evolution, a person's appearance depends on genes, the genes of the family are good-looking, and the child will be good-looking, and whether a person is good-looking also has a lot to do with his dressing, and it also has a lot to do with his cultural literacy, a person's temperament is good, even if he doesn't look good, he can cover up some, and everyone's aesthetic views are different, I think there are still many good-looking people relatively speaking.

Because people with exquisite appearances are praised, a few, and with the development of society, some good-looking people will also form a family with some ungood-looking people, and most of the children born are not good-looking. Many people who are not good-looking, and the children born of marriage are still not good-looking. Only a few good-looking people can give birth to children together, and their appearance is still very high.

A person's appearance is given by his parents, that is, inherited. Although it is an era of looking at appearance, whether a person is beautiful or not depends on his heart. A person has a good heart and looks ugly, and others are willing to associate with him.

A person is ugly inside, and no matter how good his appearance is, he can't cover his inner ugliness.

More ugly than good-looking? What kind of theory is this, there is a saying that each flower enters its own eyes, what is ugly and what is good-looking? It's just that everyone's aesthetics are different, in today's society, thinness is beauty, but is thinness really beauty?

No one can be entirely sure of this answer. In the Tang Dynasty, fat was beautiful, who can say that it was not beautiful? Look at the world with a peaceful mind, everything is beautiful, and everything has its unique existence!
