However, to assume that natural selection cannot accomplish in 4000 years, what we've done through selective breeding in ~40 years is odd to me. In humans there isn't some intelligence applying the selection,
Yes, there is. It is humans themselves. Natural selection means some get left behind. Humans work very hard to avoid that. Premies get intensive care, diabetics get insulin, and there are any number of other juvenile (and adult) diseases that don't "cull the herd" anymore. And even before modern medical miracles, humans went out of their way to deal with childhood diseases as an intelligent process. It has been a very long time since the wolves or other predators were allowed to pick off the weakest humans in the pack.
No, humans are not less robust, at least in an evolutionary sense, because evolution is all about survival in the environment as it is at the moment.
Diabetes, cancers, gastric disorders (Celiac, e.g.), endometriosis, fibromyalgia, and any number of other increasingly common disorders would contradict that. Even the now almost ubiquitous eye glasses show a declining trend in physical abilities. The increase in IVF for women who are otherwise unable to have children naturally only tends to continue the genes that create that problem.
There are no "bad" genes.
Of course there are, and you know what I meant was not "misbehaving" or any other sentient meaning to "bad", I meant genes that were involved in genetic disorders. Whether that's a gene that results in sickle cell or juvenile diabetes or whatever, that's what I mean by a "bad gene".
All traits are trade offs and to assume any trait is inherently "Bad" is to fall into the same faulty reasoning that led to eugenics in the first place.
Not all traits are trade-offs. Tell a child with leukemia or diabetes that his "trait" is actually beneficial in some way. Tell someone who is badly nearsighted and can't see anything without glasses that his trait is beneficial in some way. Tell the child who is born with a cleft palate that you aren't going to do cosmetic surgery because his trait is actually beneficial. Let the Down Syndrome kids use their beneficial trait to make good lives on their own.
You're bending so far over backwards to be politically correct that you're making ridiculous statements.
Evolution is not directional. There is not De-Evolution as a counter to Evolution.
I really don't care what name you want to apply to it, when you remove natural selection from the process of evolution, evolution no longer works. Humans have not been subject to natural selection for most negative traits for a very long time. No, we haven't managed to remove it completely and there is still infant mortality, but we're working as hard as we can to keep natural selection, and thus evolution, from working for us. By keeping natural selection from working for us, we're being "compassionate" and "social" and all those good things, but we're also allowing the non-beneficial changes to propagate and reducing the benefit from the beneficial ones.
Shortly after humans evolved tricolor vision we started loosing the ability to detect most pheromones.
I really have to figure out how the human fossil record gives you that information. No, I really don't care, because that's so far in the past that it was before existing civilizations and thus before current efforts to defeat natural selection that it is completely irrelevant to this discussion.
