Why do the first-born children look like their father?

Why is the first child like his father? After the newborn is born, the whole family will feel very happy. At this time, it is inseparable from the careful care of parents. Children's daily routine needs to be adjusted by parents. Share with you why the first child is like a father.

Why does the first child look like his father 1? Many mothers have such doubts. Why do babies look like their father when they are born? It is not until the later period that similar mother or other characteristics are gradually highlighted.

In fact, the reason behind it is very simple, that is, the self-protection function of life formed in the process of human evolution is playing a role.

Humans are mammals conceived by females, which means that the mother of a newborn is usually certain, but the father is not.

Moreover, in ancient times, men needed to go out hunting every day to ensure the family's food supply, which further deepened the uncertainty and men were very sensitive to adultery. Only when they are sure that the newborn is really their own child will they invest in raising it.

But there was no DNA detection technology in ancient times. In this case, based on the genetic instinct of survival, the baby's face will develop in a direction similar to that of his father, so that his father can determine his identity, raise him and improve his chances of survival.

According to Darwin's theory of evolution, no matter at that stage, the desire to survive is the first desire of human beings, even unconscious babies.

After the newborn is born, most mothers will insist on repeatedly describing that the child looks like the father. This is also a strategy. They tried to influence their husbands' views on fatherhood. Some people think that this may be to stimulate men to invest in newborns.

However, in ancient times, children who looked like their fathers were indeed more likely to survive than children who didn't look like their fathers, because compared with the latter, fathers were more likely to believe that children who looked like their own were related to themselves and gave them a lot of resources for survival. This unconscious behavior of babies makes us marvel at the magic of life.

However, experts in evolutionary psychology have given a more scientific explanation through research.

Evolutionary psychology is based on Darwin's theory of natural selection. According to Darwin's theory, gene particles evolved as carriers of natural selection, and formed a natural reaction that they were "adaptors" in the process of evolution. We can understand the composition of gene particles in this way. Human organs exist to adapt to the present environment.

The same is true of baby's facial organs. In order to adapt to the environment that the biological father needs to confirm his identity before raising him, their facial organs will naturally grow in a direction similar to that of the biological father.

In the process of evolution, "Adapters" have successfully solved some repetitive problems related to survival and reproduction through practice. The inversion of these specific information will be engraved into genes to form explicit behavior, so newborn babies basically look like their fathers.

In addition, belsky, Sternberg and the psychotherapist, Regg, suggested that whether the father was around or not in the early stage of children's lives and whether they were given stable investment would affect their sexual strategies in adulthood.

If a child is separated from his father for a long time in the first 5-7 years of life, it will form such a psychological expectation that the resources of parents are unstable and unpredictable, and the adult spouse relationship will not last long.

Under such psychological expectation, such children are easy to realize precocious puberty and sexual behavior disorder. In the end, they may have multiple offspring of different mothers, and each offspring can get limited and unstable investment, eventually forming a vicious circle.

On the contrary, if the child's father stays with him for a long time and gets a steady investment from his father in the first 5-7 years of his life, his views on others will be very different.

Usually, others are reliable and trustworthy in their eyes, and their attitude towards the world tends to be positive. Healthy and stable psychological expectations determine that they tend to choose a spouse for a long time. Sexual maturity is also relatively late, sexual behavior is stable, and the number of offspring is small, but each child can get relatively more investment and form a virtuous circle.

There is another phenomenon about the change of who the baby looks more like. With the change of time, the baby will gradually highlight the five senses similar to the mother.

Evolutionary psychology believes that this is the adjustment of gene particles according to the current environment after babies come to this world and find that their mothers are usually taking care of themselves, in order to please their mothers and increase the probability of obtaining living resources.

There is an effect in psychology called similarity effect, which means that people will be attracted to people similar to themselves and have a good impression on them.

The transformation of baby's five senses is also the adaptation of evolutionary mechanism to some extent. In fact, any human behavior can not be separated from these two parts: an evolutionary adaptive and an environmental input that stimulates the development and activities of the adaptive.

Under the urging of evolutionary mechanism, everyone will find the most satisfactory lifestyle in his current environment, and his current situation is the result of the interaction between the input of the current environment and his own adaptors. I have to sigh that the mystery of life is far more magical than we imagined.

Why does the first child like Dad 2 use his looks to announce to men that I am your own baby and you have to take responsibility?

The child is pregnant in the mother's belly for ten months, and when it comes to delivery, the mother can be sure that the child is her own. However, dad has never experienced pregnancy and childbirth, and because of the birth of a child, a man only needs to provide a little tadpole. In this case, it is difficult for the man to determine whether the child is formed by himself, and it is difficult to confirm whether the child is his own.

Then when the child was born, he looked like his father, that is, he announced to the man with his own appearance, you see, I look like you and must be your own baby. You should take responsibility, take good care of me and support me. At the same time, it can also make the father make up his mind completely in the state of excitement and hesitation, believe that the child is his own, and then complete the transformation of the father's role, so that men can shoulder the responsibility of being fathers, which is more conducive to family harmony.

There is a funny joke: Why does a child look like his father when he is born? Because you want to tell your father that I am your child, please take up the responsibility of raising them. Why do you look more like your mother? Because after a while, I found that my father could not count on it at all. Like my dad, it's useless. My mom is reliable. Oh, what a painful understanding.

Of course, from a scientific point of view, genes still have a role.

As we all know, 23 pairs of human chromosomes are composed of 23 chromosomes provided by parents, and each parent's genes account for half. It depends on who the child looks more like and which parent has the stronger dominant gene. If the father's dominant gene is stronger, then the child looks more like the father. On the contrary, it is more like a mother.

Why is the first child like the biological protection instinct of Dad 3?

There is a saying among the people that newborns, like their fathers, are as lovely as infants, and they are all creatures' instinct to protect themselves. The parent-child relationship between newborn and mother is obvious and established.

Comparatively speaking, the explicit relationship between newborn and father is not so clear. Therefore, for newborns, they look more like their fathers, intuitively showing their blood relationship, and expressing to their fathers with their own faces: I am your child, and I am more likely to be raised by my father, which is conducive to survival.

Psychological influence is at work.

In fact, this statement is more about people's psychological function. Most people tend to believe what has become common sense in their minds.

As the saying goes, three people make a tiger, and the more rumors spread, the more "true". However, this rumor lacks scientific basis and its credibility is doubtful.

Hereditary dominant gene

With the popularization of science education, the basic idea of genetic theory is well known to women and children, and the appearance of children is closely related to the inheritance of parents' genes.

We always hear that boys are like their mothers and girls are like their fathers. However, children get half the genes from their parents, and the ability to influence them is equally divided. It is the parents' genetic combination that affects their looks.

After all, children are separated from their parents and grandparents by genes. Parental genes are divided into dominant genes and recessive genes. When the dominant gene of the father accounts for a large proportion, the child will be more like the father.

Inherited recessive genes are just invisible and are likely to be reflected in future generations, which is the legendary phenomenon of genetic atavism. Children's looks can always be found in ancestors with similar dominant genes.

What characteristics of parents are more likely to be passed on to future generations?

The children of actors Du Jiang and Huo Siyan, uh-huh, were called "ugly dolls" by their fathers at birth. His parents' big eyes, double eyelids and high nose can't find any trace on the child's face.

Apart from one example, which characteristics of parents are more easily passed on to children?

Ears: According to the scientific investigation report, ears are most likely to be passed on to the next generation. If the father or mother has ears, there is a 70% chance that the child will have ears.

For example, He Jiong, the famous host of Hunan Satellite TV, copied and pasted his father's ear almost perfectly.

Skin: In terms of skin color, ignoring the diet and postpartum care of pregnant women, the skin color of children is mostly the combination of parents.

If one side is white and the other is black, the child's skin color is neutral, between black and white; If both sides are white-skinned, it is very likely that the child will be white-skinned; Other skin colors are the same. In terms of skin quality, oily skin may be hereditary. If both parents have oily skin, they are more likely to pass it on to their children. If it is a personal factor and lacks care, it is unlikely to be inherited.

Intelligence: As early as19th century, scientists put forward the basic genetic factors of intelligence, among which the genetic effect should not be underestimated, accounting for about 30%-80%. Genes related to intelligence are concentrated on X chromosome, and girls have two X chromosomes, which are more affected in theory.

But generally speaking, the heritability of intelligence increases with age before adulthood, from 30% to 70% to 80%, and tends to be stable after adulthood.

It can be seen that it is not limited to the influence of genes. The younger a child is, the more suitable it is for intellectual development, which is conducive to his intellectual development.

These two parts of children's facial features have great dominant genetic advantages.

Eyes: the shape of children's eyes is easy to inherit the characteristics of their parents. Big eyes are dominant genes relative to small eyes, so parents only need one big eye, and it is very likely that their children will have big eyes.

Long eyelashes are also dominant genes relative to short eyelashes, which are the same size as eyes.

Nose: Generally speaking, the genes of the nose will last until the child reaches adulthood. High nose and wide nostrils are dominant genes.

Because of the persistence of genes, children with short noses may grow up with tall noses.

Parents and children, no matter what they look like, are gifts from their parents. Appearance is appearance, and it will get old eventually. What is more important is the cultivation of parents, giving children a healthy and happy growth environment and accompanying them to grow up.
