In fact, not only people, but all animals love beauty. Many animals show their faces when courting. Strong animals tend to compete for mating rights, while birds with beautiful feathers can win the favor of the opposite sex. The love of beauty is the nature of all animals, and it is also necessary for reproduction. In the animal world, having a strong body and beautiful feathers itself represents the health of the body, and having a healthy body can ensure the reproduction of species. In human society, it is more convenient to look good.
For example, we often say that love at first sight has a great relationship with looks, and it can even be said that there is a 100% relationship.
Why does everyone like to look good? This should start with the purpose of species existence. The existence of any species has two most important purposes, the first is survival, and the second is reproduction. Any animal, including people, is no exception. Therefore, in human society, occupations related to survival are often the most concerned, such as investment and financial management, medical care and so on. Occupations related to reproduction are the second, such as maternal and child care, education and training. Although they are the best in the industry, the attention of other occupations is far less than these two categories. And then what? Love beauty? The heart is closely related to the second purpose of species existence: reproduction.
Any species will continue its species through reproduction, but the competition for survival is extremely fierce. To ensure the continuation of species, we must pass on the best genes. So how can we identify excellent genes?
From the appearance alone, people who are usually good-looking have healthier bodies and smarter brains. Speaking of which, many people may have to cite counterexamples. Many famous successful people are not outstanding in appearance. Yes, but the success of these successful people lies mainly in their perseverance and determination in the face of adversity, not in their excellent genes and smart brains. Most of them can't even get into Mensa.
Some scientists have studied this. According to the judgment of public comments, participants are divided into good-looking group and bad-looking group. The results show that the average IQ level of the good-looking group is significantly higher than that of the bad-looking group, and the overall health status of the good-looking group is better than that of the bad-looking group. Although the sample data of this study is limited, it is not an authoritative study, but it can explain human beings from the side? Love beauty? Reason.
In this case, will human beings evolve better and better in the future? This is indeed possible, because good-looking people have more reproductive advantages, so their genes are more likely to be passed on. In fact, judging from the old photos handed down, I personally think that modern people seem to look better than those in the past.
But the essence of evolution is to adapt to the environment, so as to obtain better viability. Whether it looks good or not has nothing to do with survival.
Moreover, evolution is a passive behavior, which will go through a long process, regardless of human subjective will. Therefore, for thousands of years, although the overall appearance of human beings seems to have made some progress, there has been no particularly obvious change. In addition, there is no such thing as a camera before, and we can't compare it, but at least it is unchanged from the perspective of bones. And humans are different from other animals. Under the system of human civilization, everyone has the opportunity to get the right to reproduce, so the situation of handsome guys and beautiful women everywhere will not happen. Beauty and ugliness are a very subjective view, and there is no fixed measure.
