Viagra & Evolution

Of course one very simple explanation is that it is a reaction to overpopulation.

Interesting suggestion. I have a couple of observations, though.I'm reminded of something I heard, quite some time ago, about an experiment were researchers kept mice in extremely over crowded conditions and discovered that some of the mice became sexually attracted to members of the same sex.Wouldn't your suggestion and the experiment that I recall (if I'm recalling accurately) mean that, in effect, evolution is operating to the detriment of some individuals in favor of the rest of the population? If so, I must admit that I'm hard-pressed to conceive of an evolutionary explanation for such a phenomenon. It seems counter intuitive.

That said (and you have my permission to call me heartless), I don't want [people with Down Syndrome] to reproduce.

Let's have a bit of fun, and see if we can give the cdesign proponentists a little ammunition. (Seems to be the least we can do since they give themselves so little to work with.)I'm assuming the reason that you don't want them to reproduce is because they reduce the overall fitness of the species and are, on the whole, a drain on resources.What steps, if any, would you be willing to accept for society to discourage them reproducing? I have my own conclusion to this question, fairly firmly held, that I'll share. But I'm curious to hear what you (or anyone else) has to say on the matter.
