In the human species, we've really fvcked up this whole process. I would probably be dead with my crappy eyesight and so forth. "Success" in genetic terms is how many offspring you can send off. That seems to have very little to do with physical and mental capabilities of our species worldwide compared to other non-domesticated animals.
Agreed with you up until that point. While modern medicine may keep a lot of people alive who possibly don't "deserve" to be alive, it also keeps a larger variation in the human population alive. Meaning we are more fit, as a whole, to survive any 1 single catastrophe. Your eye sight may suck, but you may end up resistant to a new strain of virus. In more dangerous times, specialization would be necessary, but specialization sets the species up for common weaknesses.
I'm just saying that we fvcked up the natural selection process. Whether that's a good thing or a bad thing is up to the eye of the beholder.
Evolution is not purpose driven. It is not designed to result in an optimized species. It is a cold unfeeling thing that only cares about what works today. If a killer virus shows up tomorrow that takes out 90% of the population, noone will care about bad eyesight, laziness and premature balding... Killer virus resistance will be the most important trait to have... If that virus never shows up, killer virus resistance serves no purpose.
That is actually a good demonstration why a diverse population is advantageous for the species as a whole - better chance of killer virus resistance being present in someone when the big one shows up...

We've been playing God since the dawn of agriculture. We're now in a position to influence our own evolution directly and have indeed been doing it indirectly for thousands of years. And quality of life keeps getting better and better as a result.
Hey, I'll be the first to admit it's good from my perspective. I wouldn't be here if our species was still on an entirely natural selection in the wild side type of existence.
There are people out there that would disagree though.
People that think we should still be on a survival of the fittest type of species where physical strength is often seen as the most important factor.
People that see the current state of technology, economics, politics, etc. as our "environment" now and don't like seeing that the most "successful" (economically, politically, etc.) individuals are not the same people that are "successful" biologically.
(No social welfare programs, help for the poor, etc. would help them realize their vision of only the most "successful" surviving)
People that see "weaker" / "less fit" individuals as a drag on humanity. As in "why should I have to worry about this guy in a wheelchair or someone with cerebral palsy when they're not contributing to society".
Ok, I'm on the side that genetic variation is a good thing. There are people out there that don't agree that helping out the "weak" is beneficial.
