One, 5 million years after the disappearance of men
The man's life core - 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 vulnerable to injury, so Be kind to men in your life.
Yin and Yang, male and female, male and female, male and female, from the day life is born, the world is composed in such a balanced way. However, the recently published New Scientist magazine reports that British scientists have found, based on recent research, that the human male is gradually dying out.
1, genetic diminution is due to gene mutation
Researchers believe that the original human Y chromosome contains about 1,500 genes, but, in the long process of evolution of about 300 million years, the Y chromosome function gradually degraded. Now the number of genes in charge of the human Y chromosome has been reduced to about 40. Researchers expect that after 5 million years, when all the genes on the Y chromosome have disappeared, there will be no more males in the human race.
The cause of the diminishing genes on the Y chromosome is genetic mutation. A 30-year-old man's sperm DNA is replicated 350 more times than a woman's egg; and with each replication of the chromosome, the likelihood of a genetic mutation is a little higher. Genetic mutations can prevent the new generation of chromosomes from inheriting 100 percent of the function of the previous generation of Y chromosomes, so that after a while, the function of the original Y chromosome no longer exists.
2, the evolutionary process of gene loss is a common phenomenon
Recently, research has also found that the vulnerability of the male does not lie in the sperm chromosomes are particularly vulnerable, but in the process of evolution, the male sex chromosome genes are particularly susceptible to loss or loss of function. The reason for this is that the Y chromosome, one of the XY chromosomes in males, is vulnerable compared to the XX sex chromosome in females, and once the genetic information on the Y chromosome is lost, it is unlikely to be replenished by information on another X chromosome, as can be the case with the XX chromosome in females. It has been found in 5-15% of severely infertile men that their infertility is caused by the partial or total absence of many genes on the Y chromosome.
In fact, many of the genes on the Y chromosome that are now out of function (pseudogenes or junk genes) suggest that the wear and tear or depletion of genes continues, and that even those genes that are critical to the course of life are missing. The Human Genome Project also found that many genes on chromosomes other than the sex chromosomes were inactivated or lost. This also adds to the proof that the absence of genes during evolution is a universal phenomenon. But since the Y chromosome happens to be complementary to the X chromosome, the loss of its genes is having a huge impact on evolution.
Two, do men really tired
Men are trees, women are vines. Men are like mud, women are like water. Men are masculine, women are feminine. In the traditional culture of moral concepts under the inculcation, a good man will always have tears, iron bones, is really a great man.
Thousands of years ago, men hunted in packs, lived in caves, and bossed women around. However, when a woman's pain and depression, you can cry loudly, the man sad, but had to endure the pain and suffering, alone in tears; women in tears, let a person's heartache, men in tears, let a person laugh; women stay at home to teach their children, it is a good wife and mother, the man is idle in the family home, it is helpless and incompetent.
It must be recognized that the man in order to support the family, outside to make money, to suffer the pain and suffering of the human world, a person to bear the wind and rain, and strive to create a wife, for the children warm and sweet.
Men's work in the trouble, the family in the bitter, no one to talk about, had to be in the drunken numbness and erotic pleasure-seeking in the bitter degree of life. Confidant can have a few, who can grasp, in the emotional mingling in the love is not confused, really do "home red flag not, outside the colorful flags fluttering"? Women all the troubles, bitterness and helplessness, can be told to the girlfriends of close friends, but also to the opposite sex friends to tell. Women's tears is a tender sword, is the enemy to win the magic weapon; men line? You snot a handful of tears, more people will feel your weakness and incompetence, light is disgusted by others, heavy is scorned.
"The truth stays in the heart, the bitterness is poured into the wine, the love grievance is locked in the home, the tears flow in the belly." This is the true portrayal of contemporary men. Very miserable and helpless. Men are in fact also very vulnerable, sad, also want to find a gentle shoulder to lean on. When the mood is irritable, also look forward to someone to talk properly, or through a quick cry on the scene. But the reality is that no one knows your pain, no one understands your sorrow, a handsome man behind, hidden deep in the heart of a heart is not easy. Do men want to win and afraid of losing, so, live a very depressing, live a very hard, more live a tired heart.
Nowadays, society is a society that only looks at the results, not the process. Behind a successful man, there must be a qualified and competent woman. The man gets the praise and honor, what can the woman get? The vicissitudes of the years mercilessly left on the face, pay the hard work hard to have a happy return, often get not much, lose a lot, get is better than not get.
Their own man lost, the woman will have a good day? And the woman is a success, but may not be recognized and accepted by society, the double pressure of the family and society, often make them overwhelmed, and finally lead to a human tragedy. Therefore, to be a man is very tired, to be a woman is very difficult, are living a very difficult life, are in pain and smiling.
Men are tired, but tired of harvest, tired of achievement, tired of value.
