Seriously? This is part of your argument? Yeah, I'm not going to take ANYONE seriously who'd actually group those who are genetically nearsighted in the same classification as those who have severe mental disabilities.
I think you may have missed the point. In the struggle for survival that made human beings what they are, sight impairment would have been at least as bad for an individual's survival chances as some mental disabilities.
Never mind - why not stop being coy and mention the solution model you have coyly hinted at?
It is a little known fact that the purpose of evolution is to improve the primary energy transformation function of animals, which involves the digestive system. The first modifications were to the mouth, with variations in size, tongue, teeth (especially teeth that were evolved to eat certain foods.) With the ruminants, such as sheep and cattle, the stomach was vastly improved to be able to digest grasses and readily available foods containing fairly low energy. When man came along, the focus of evolution was NOT the brain. Evolution is searching for the perfect as*hole.
The modifications pretty much failed. Teeth are one of the weakest, most inefficient systems in the human. They are prone to bacteria collection, decay, loss, bone loss, etc. Not a great innovation and they don't last a lifetime, especially without artificial care.

They last long enough. Back on the savannah, once you'd procreated and managed to get your offspring through their teens, nature would pretty much consider you disposable.

You do know that the statement was just the lead-in to the joke, right? Obviously, the most important part of evolution was development of the pecker.

There is very little evolutionary pressure for teeth to last a human lifetime. Once an individual is past reproductive and primary child-rearing age, very little evolutionary pressure will be exerted by their continued survival, or lack thereof, beyond that point.
Evolution is about producing another generation, not having nice teeth in ones dotage.
Hat tip to Dane_in_LA:
I should have read your response before I said essentially the same thing!

I guess back -- who knows when -- people died at around 45 years of age. Exceptions could be longer.
Humans only need to be smart enough to survive, and live long enough to mate. Sure, we can be idiots pretty often, but we are still smart enough to live long enough to reproduce. Anything that happens beyond that is just a bonus, at least when you compare us to the rest of the animal kingdom.
