A future that is dark for men

Adam's Curse -

"Genetically speaking, the big difference between men and women is that
where women have two X chromosomes, men have one X and one Y chromosome.
It is surprising that one chromosome difference out of our total of 46
can have such an important consequence. Is this relatively small genetic
variance really sufficient to explain the differences between the sexes,
not just the physical but the psychological, social or even cultural?
Prof Sykes takes us on a fascinating exploration into the science of sex
and gender, and takes a scientific look at what makes men tick. His
research has shown that the all-important male Y chromosome is getting
smaller. As the generations pass the female X chromosome is taking over.
Women are winning the evolutionary battle of the sexes. The shocking
conclusion is that men, slowly but surely, are headed for extinction."

Can we survive the onslaught?

  • woow!! i see danger if men can go extinct because women will no longer give birth.

  • It is true that men are faced with extinction. This is because if you can take a look to any public or private institution men are out numbered by women. Why not follow China as an example for screening each an every pegnant women after pregnant. If it is found that the pregnant women carry a baby girl, she must be forced to make arbotion.

  • yes it is true we as men are facing extinct.there is a need for control measures to maintain the balance between men and women.

  • man are faced with extnction, but if we want to overcome this, there must be an increase in tax for women who bear baby girl and those who bear boys there must have a reduced tax with incentive so that most women will be couraged to have son.

  • yes, there is an extinction of men due to smaller y chromosome and there is a need of scientist to create "if possible" an artificial or to increase y chromosomes for men.

  • since man are facing extinction does this mean that on earth they would be only women left which means the won't be any repraduction. is the world coming to an end? or the scientistst are going to develop a way in which woman can produce babies since man will no loner be existing.

  • hi Lethabo

    i suggest that next time you must just edit your comment than doing mistake time and again.

  • hi Puli

    i like your suggestion, i also believe that the only solution will be that of artificial Y chromosomes.

  • yes it is true that man are extinct than woman.this cause the man to marry many woman and woman are suffering.if possible for scientist to upgrade the medicine for woman to produce the baby boy

  • since it is known that the Y chromosomes are getting so i want to know why is the Y chromosome getting smaller? what are they planning to do in order to prevent the extinction of men? did they try to find out why the Y chromosomes are getting smaller?

    By Blogger lethabo, at Friday, March 24, 2006 11:44:00 AM  

  • Indeed,men are faced with extinction.Scientists may, for example discover a medicine for pregnant women(with baby boy inside)to drink during pregnancy. As results, a baby will be born with a strong y chromosome.This will be useful for future generation.

  • Hii every one

    It is true that men are faced with extinctoin.Only God can prevent the men axtinction.The bible on Luke 1:37 says that "nothing impossible with God".This means that we have to pray and ask Him to prevent men to go to extinction.

  • The discussion of the "Y-Chromosome" is a lot more intricate than the article suggests. The research done on the DNA of people, as previous posts suggest, points towards one of two conflicting theories or hypotheses about the beginning of the second exodus of Homo sapiens out of Africa after the population bottleneck after a theoretical volcanic winter (originating in the Far-East). The first is that of the "African Eve" and "Eve's" seven daughters, a more widely accepted theory, which is supported by the findings of David Reed in his research on the co-evolution of lice (watch this space...)and humans. The second hypothesis is the multiregional hypothesis, suggesting that contemporary populations of hominid species may have interbred and hybridised.

    The interesting fact is therefore not that there is a posibility that the male chromosome is losing the evolutionary batle, but rather how natural selection over time through a population botleneck produces accelerated combinations of genetic material, not seen in a more variant population, as humans were many thousands of years before the bottleneck occured.

  • Clearly women are the fairer and "superior" sex, but what are women without men?

    bru even if you need to beg, borrow or steal one, get a sense of humour!!!! This topic was meant to spark soe interest and tickle your funnybone, not make you get your knickers in a knot about the details.
    Take a chill pill or something!!
