> Yeah...speaking of stupid and weak people, Darwin's evolution wouldn't be working it's magic on the human race anymore because stupid people and weak people are still mating and spawning more stupid and weak people. In fact, a stupid person may mate more than your average smart person. So, basically, shouldn't we be turning into a race of stupid and weak people? ummm...did I just steal that idea from H.G. Wells?

Actually, that idea doesn't even require the whole evolutionary theory -- just the principle of natural selection (which I can embrace without reservation). I've frequently considered how modern medicine has in some small ways countered the positive effects of natural selection on the human gene pool.

For example, someone like myself, who can't see three inches past his own nose without contact lenses, would have had zero chance of surviving -- much less marrying and producing offspring -- in the pre-glasses era. Nowadays, I and millions of others like me are free to contribute horrible vision to our posterity. Same goes for genetic susceptibility to ailments that are now treatable but would have been debilitating a few centuries ago.

By helping genetically "inferior" people like myself to survive and reproduce, modern medicine causes the human gene pool (in Western nations more than others, I guess) to produce "inferiors" in greater numbers. So over a great amount of time, the human gene pool worsens.

If this process went on unchecked, I could see it becoming a problem in the distant future. But it seems most likely that the next great wave of medical advances, in which we learn how to manipulate individual people on a genetic level, will serve to counteract the effect. Whatever ethical, religious and other problems genetic manipulation will present, it at least stands to reposition medicine as a cure for bad genes rather than a crutch for them.

Maybe no contact lenses or corrective surgery will be needed by the grandchildren of my wife and I, who are both blind as bats.
