What happened to men's day?

1 .5 million years later, humans disappeared.

The core of a man's life, the male Y chromosome, not only determines the quality of human evolution, but also determines the direction of human evolution and whether it can evolve and reproduce, and the Y chromosome is particularly fragile, so be kind to men in life.

Yin and Yang, male and female, male and female, male and female, from the day of birth of life, the world is so balanced. However, the recently published "New Scientist" magazine reported that according to the latest research, British scientists found that human males are gradually becoming extinct.

1, the genetic decline is due to gene mutation.

Researchers believe that primitive human Y chromosome contains about 1500 genes. However, in the long evolution process of about 300 million years, the function of Y chromosome gradually degenerated. At present, the number of genes controlled by human Y chromosome has been reduced to about 40. Researchers predict that after 5 million years, when all the genes controlled by Y chromosome disappear, there will be no more men in human beings.

The reason for the genetic decline of Y chromosome is gene mutation. A 30-year-old man's sperm DNA is 350 times more replicated than a female egg; Every time the chromosome is copied, the possibility of gene mutation is greater. Gene mutation will make the new generation chromosome unable to 100% inherit the function of the previous generation Y chromosome, so after a period of time, the function of the original Y chromosome will no longer exist.

2. Gene deletion is a common phenomenon in the process of evolution.

Recent studies have also found that the fragility of men is not that the chromosomes on their sperm are particularly fragile, but that the genes on male sex chromosomes are particularly prone to lose or lose their functions during evolution. The reason is that the Y chromosome of male XY chromosome is fragile compared with female sex chromosome XX. Once the genetic information on Y chromosome is lost, it is impossible for women's XX chromosome to be supplemented by the information on another X chromosome. In 5%- 15% of severely infertile men, it was found that their infertility was caused by partial or total deletion of many genes on Y chromosome.

In fact, many nonfunctional genes (fake genes or junk genes) on the Y chromosome indicate that the wear and tear of genes continues, and even those genes that play a key role in the life process will be missing. The Human Genome Project also found that many genes on other chromosomes except sex chromosomes were inactivated or lost. This also proves that gene deletion is a common phenomenon in the process of evolution. However, because the Y chromosome is just complementary to the X chromosome, its gene deletion has a great influence on evolution.

Second, being a man is really tiring.

Men are trees and women are vines. Men are like mud and women are like water. Men are masculine and women are feminine. Under the influence of traditional cultural morality, a good man will always be a real gentleman with tears and iron bones.

Thousands of years ago, men hunted in groups, lived in caves and bossed women around. However, women can cry loudly when they are in pain and depression, while men can only endure pain and suffering and cry alone when they are sad; Women cry, which makes people feel distressed, while men cry, which makes people laugh; A woman who stays at home to teach her children is a good wife and mother, and a man who stays at home to do housework is helpless and incompetent.

I have to admit that in order to support my family, men have to work hard to make money outside and have to bear the pain and suffering of the world. A person bears ups and downs and tries to create warmth and sweetness for his wife and children.

Men's troubles at work and family depression have no one to talk to, so they have to spend their lives in drunkenness and erotic pleasure. How many confidants can there be, and who can grasp it well, not to be confused by feelings in the emotional blending, and truly "the red flag is not at home, and the colorful flag is fluttering outside"? All women's troubles, depression and helplessness can be told to close friends or friends of the opposite sex in the boudoir. Women's tears are a gentle sword and a magic weapon to defeat the enemy; Can men do it? Your nose and tears will make people feel that you are weak, from being rejected by others to being spurned.

"The truth stays in my heart, I am depressed in the wine, my feelings are locked at home, and my tears are dripping in my stomach." This is the true portrayal of contemporary men. Very sad and helpless. Men are actually very fragile. When they are sad, they also want to find a gentle shoulder to lean on. When you are sad, you also expect someone to talk to you well, or you can all cry quickly. But in reality, no one knows your pain, let alone your sadness. Behind the handsome guys, there are not easy hearts. Being a man wants to win and is afraid of losing, so he lives very depressed, hard and tired.

Today's society is a society that only looks at the results, not the process. Behind a successful man, there must be a qualified and capable woman. Men get praise and glory, what can women get? The vicissitudes of the years are ruthlessly left on the face, and it is difficult to get a happy return for hard work. Often not much is gained, but a lot is lost. It's better not to get it if you get it.

If her man is frustrated, will this woman have a good life? However, women's success is not necessarily recognized and accepted by society. The double pressure of family and society often makes them overwhelmed, which eventually leads to a series of human tragedies. Therefore, being a man is very tired, being a woman is very difficult, and living is not easy. They are all smiling in pain.

Men are tired, but they are rewarded, accomplished and valuable.
