The Y Chromosome will be gone soon. Well, in 4.6 millions years.
While the visual of Human Stud Farms is amusing, the planet will be a lifeless husk well before we can go down that road. Still and all, it’d make a hell of a Discovery Channel movie !!
Fascinating bit of real science there, though. I’d no idea that this one chromosome has to do work-around to remain in the mix, so to speak.
Your cite is, shall we say, “less then definitive” on the timeframe you quoted.
What’s a coupla hunnerd thousand years between friends?
“In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period, just a million years ago next November, the Lower Mississippi River was upwards of one million three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing-rod. And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen. There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.”
