Sooner or later, we would've advanced in life-saving, or disease-curing. All of the products we use today are derived from natural things. And even now, most plants naturally grown tend to have a better effect than any man-made product. We've had these tools, and more, at our finger tips, so why not use them?
Evolution? No, none of this is evolution. Evolution would be a jump from a bird to a bird-fish, and to a new fish. I, for one, refuse to believe that I came from some primordial ooze, or even an ape. What you all are looking for is the word adaptation, and possibly even mutation. Viruses adapt to change, as do ALL organisms. Survival of the fittest is key in wiping out that which cannot adapt, but isn't always the right path to follow. Man has adapted to the basic diseases that roamed the planet, the diseases adapted to man's resistance--everything learns, in a sense, from the environment and community around it. Also, most people classify mutation as something horrible, but that isn't necessarily true. Mutation seems to help in some cases. Take, for instance, those immune to AIDs. AIDs is horrible, but when something is infected with the disease, that thing can adapt--or mutate--to become resistant, if not immune.
Don't expect to evolve in to some higher form of human and sprout wings or something, that will never happen. BUT, thanks to the technology which allows most of us to be here, we can someday achieve that which we can not through natural means. HOWEVER, thanks to that same technology, and the stubborness of those in power, we are quickening our journey towards the end of all we have worked so hard to achieve. Fortunately, the world will most likely end before then, in one way or another, and we won't have to worry about our own stupidity bringing about our demise.
Sure, the gene pool does have it's weak links, and those weak links are mostly weeded out or protected against threats. Natural selection still exists, though not as blatantly obvious as it used to be. If some new or highly adapted form of virus were to strike humanity and nearly wipe it out, then you can thank natural selection for that. But you know, in that process of elimination, you lose a lot of the progress made thus far in technology and human "perfection", so to speak.
But you've also got to think... Since everything is constantly in a state of degradation, what was the gene pool like say... 1000 years ago? I won't say 1,000,000,000 years ago, because I refuse to believe the earth has actually been around that long and yet has only progressed this far, or is even still here. Anyhow, the gene pool 1000 years ago would've been a lot stronger than it is now, so if survival of the fittest was constantly wiping out the weak, why aren't there very many strong left?
Huh... I've lost my point and train of thought... I'll be back later...
