I can see your logic on that. I can’t see it leading to a majority of the population becoming infertile, but I can see it leading to a much larger proportion of the population in the future being so. If there is a genetic trait or abnormality (possibly a recessive one) that can make infertility more likely then that trait would by it’s nature be self limiting, causing some of its carriers to be unable to continue it.

Treating infertility through drugs would not stop the underlying problem if it was genetic, but mean that more people in the next generation would be likely to carry the trait and therefore cause a likely increase in individuals where it becomes dominant or where they are subject to the right environmental conditions that the problem emerges.

I still like Weird Al’s take on that song better though.

Gotta love Presidents of the United States of America.

Still, six at once? That can’t have been too much fun.

Or we could just stop treating people with wisom tooth problems, that would speed it up somewhat…

He’s Gump, He’s Gump
What’s in his head?
He’s Gump, He’s Gump, He’s Gump
Is he in-bred?”

it makes a nice sound

Either that or it’s a rather severe weight-loss programme.

Does the extra rib thing have any benefits/problems?

So, having them out could increase the evolutionary effect: more people dying because of the surgery, even if the ones that the surgery works on live pain-free lives afterward.

That song’s going to be stuck in my head all day now.

Wouldn’t want the descendants of Cletus to be ruling the world though… I’d better get on with it and crank out a hundred or so children.

Also I did a thing on my blog proposing that fertility drugs could indirectly cause the entire human race (through evolution) to be infertile. The logic was questionable but I think it was funny.
