Have you heard about the decrease in Y chromosomes?

Yeah some horrible books have been published on it. Adams Curse(Bryan Sykes) and Descent of Men(Steven Jones), I am convinced these men are self hating feminist. But your looking at around 5-10million years, anything can happen in that time and the males of other animal species have survived without the Y chromosome, the job can be taken up by another autosome. In the next hundred years gene replacement therapy could fix this though.

WHAT? The only way that the Y chromosome would disappear is if the women killed off all the males and started cloning themselves. I'm curious what street you heard that on.

There have been slight drops in numbers of male births, although there are still more males born than females. Certain types of pollution appear to also be selecting males for early death. On the other hand, certain practices in in vitro fertilization have increased the chances of a male birth to as much as 90%. And in some countries where males are more valued than females, selective abortions have dramatically increased the percentage of males being born.

Males are not going to disappear from the equation. Always be cautious about reading too much into any article like the one you read.

For as long as birth records were kept 106 males were born for every 100 females. But more males have genetic defects than females, and many of those died before the first birthday. If there is now is a decrease it could be that some of these defects are found before birth and the pregnancy is terminated.

As for my family could not prove males are decreasing. I gave birth to 4 males. My siblings were 3 males, 1 female- second generation- 9 males, 2 females- third generation 6 males, 1 female (so far).

my wife just watched a newscast on it just recently. The jist of the newscast is it is happening and it's being caused by all the chemicals in the environment, cleaners, plastics, everything else. It's also happening in the animal kingdom. I also noticed a few years ago, that there sure seemed to be a hell of a lot of little girls at the parks and in the schools. I have 2 daughters, and now a son. But if you think about it, one male can impregnate a multitude of women, so i'm not too worried about the species.

Well, they use to think that the Y chromosome was shrinking, but actually it's not:

the decrease in 105:100 (male:female) ratio is due to pollutants in the air and water supply - no joke.

To be honest I think that you probably found this out from an unreliable source - could you give us a link to anything that proves this?

There have always been more females born than males, something around 51 or 52%. Now that we don't have to chase down saber tooth tigers anymore or chase the visagoths from the cave entrance anymore we are becoming superfluous.

I've heard that....looked into it.

Turns out its just a bunch of mumbo bull talk....

y chromosome is doing just fine.

XX = Female

XY = Male

I think you may need a source for your statement.
