DON’T TELL MEN THIS! But, they are about to become extinct. I know, I know. This is startling news for me to receive, too. Because, I like men. I mean, I really, really like men, and the thought of living on a man-less planet is kinda creepy. But here are the facts, according to some forward thinking biologists. We recently learned to manufacture sperm.
Women have very intelligent bodies. Our double X chromosome protect us from many diseases because if we inherit a deadly disorder on one side of our X chain, there’s a good chance we have a healthy back-up X to compensate. We also express more genes overall than males, who have one X and one Y. The X chromosome – one of 24 chromosomes found in human cells – is much larger than the relatively puny Y (sorry guys, size, apparently, does matter). Our X contains 1,098 genes to the Y’s 78.
This means that female mammals contain over 1,000 more genes than males. To compensate for this, the female body switches off one X chromosome – quite randomly – in each cell. Men often fall victim to diseases carried on the X chromosome because they don’t have a back-up copy of the gene on the second chromosome. Poor babies. More than 300 conditions have been linked to the X chromosome so far, from heart disease to cancers, but since us gals have another – usually healthy – copy of the X chromosome, we are shielded from the full impact of these disorders. Now multiply that fact by about one-hundred thousand years of dating, mating and procreating and you start to see how men might become an endangered species.
So there’s the writing on the wall that men may be on their way out. Add to this chromosome problem, the facts that male premature infants are less likely to survive, and the fact that, well, the male lifespan is shorter, and the picture becomes clearer.
A few years ago, I sat on an airplane beside a young, handsome, smart, version of an XY chromosome and he spelled it out for me. He could do this because he was a human biology professor in Great Britain. And he spelled it out with such a lovely English accent. I told him I was writing a book about feminine intelligence and I asked him to give me his opinion on the intelligence of women’s biology. He just shrugged his shoulders and said, “Well, for starters, it’s been calculated that in 125,000 years men will be extinct.”
I laughed at that. “Don’t you mean that the entire human species will be extinct then?”
He looked at me with a stone cold stare and calmly stated, “This week the first human infant was born using frozen sperm and a frozen egg. Don’t you think that in 125,000 years, you girls will have figured out how to make sperm for yourself?”
Apparently, this year we did. Use it wisely, girls.
