Gategory: Health | Key words: Oxford University professor of human genetics Brian Sussex accepted an interview with ABC claimed that the male Y chromosome because of unique unable to repair the damage caused by genetic mutation, as human development is being progressively degraded, according to Y Chromosome gradual demise of the speed of calculation, he considered that men will not escape the ultimate fate of extinction, about 125,000 years later, perhaps on the men on the planet from extinction, the Earth will become a true sense of the "daughter of country."
No men of the Earth
As early as six years ago, the Oxford University professor of human genetics Brian Sussex on in his book "Adam's curse," a book described a man on the planet could be extinct from the astonishing theory. Sussex professor in a recent ABC interview, detailed forecast, "not men of the Earth" will be what look like.
Sussex professor said, Y chromosome is unique to the male chromosome, it was decided a fetus is male or female of the basic conditions. Y-chromosome from the father to the son of genetic and women who do not exist with Y Body-color. He said that the earliest human beings "original version" should be female, male female genetic variation is only a product of it. Sussex professor explained: "In theory, genetic mutation of the men are women."
Earth's Jiangcheng "daughter"
Sussex professor said, and different from the other chromosome, male-specific Y chromosome is not possible to repair genetic mutation brought about by injury, it is with human evolution and the gradual degradation, according to the Y chromosome gradual demise of the velocity of about 125,000 Years later, Y chromosome to be completely lost their function, which means that men may be from time to extinction on Earth.
Sussex professor explained: "every generation, have one percent of men will have the Y chromosome gene mutation, which will reduce their ability to bear children 10 percent. Chengshuangchengdui and the X chromosome is not the same, Y There is only one chromosome, unable to repair their own mirror copy of the defect, so it's not always gene defects were repaired law. "
Women can be "alone" and multiply
Sussex professor said, even if the men did not exist on the planet, women still can use the "single-sex reproduction" continue to multiply, so the technology is not science fiction, but in sight of reality.
Sussex, Professor, University of Newcastle people Members have already mastered the male bone marrow cells grow through the "artificial sperm" technology, the next step of their plan through the female bone marrow cells to nurture the "artificial sperm." Once the experiment successful, up to 35 hours, women can To propagate their own fertility and future generations. However, the stem cells grow through the female out of "artificial sperm" lack the Y chromosome, they "single-sex reproduction" of all future generations of girls.
Prisoners and accident Kuangxiang
Experts said that if no man on earth, then many things will disappear with, such as sports bars, "Playboy" magazine and other men, men love a Ferrari sports car, and so on. Another certainty is that no man on earth there will be fewer wars, the U.S. prison in the number of prisoners will be Kuangxiang 97 percent, the accident mortality rate in the United States will also Kuangxiang more than 70 percent.
Although the Y chromosome may have to have 125,000 years before dying out, but men who are facing a more pressing crisis: in the past 50 years, the male sperm count has dropped sharply by 20 percent, experts think it may face greater and men Pressure, alcohol abuse and related issues such as environmental pollution.
Men's organizations were "bombarded"
Sussex professor said, when his men will be 125,000 years after the extinction theory, a number of men were organized by shelling, Sussex said: "I have received a lot of hate mail, in the letter they asked me: 'How can you betray your own gender »'"
However, the University of London professor of genetics, "Y: the degradation of men," a book by Steve Qiongsiboshi is Professor and Sussex, "we were amenable to the idea," Qiongsiboshi also said the men disappeared just a matter of time .
Demise of the disputed time
However, for the ultimate demise of the Y chromosome of the time the scientific community there are still enormous controversy. Although Sussex professor male Y chromosome in 125,000 years after the complete loss of function, but the Australian National Geneticist at the University of Zhan Nige has said Professor Lei Fusi, Y chromosome must have at least 1,000 years before disappearing. Graves also said that even if the Y chromosome disappearing, there are still men may not perish, but may appear "Variant", to differentiate into several types.
