The reason people aren't evolving. (A question I get a lot.) is that there is no need. There is no circumstance that says that only the fittest people can breed, thus no human evolution. There, thought I'd just put that out there.
Actually, we're still perfectly evolving. Just not in the way we used to.
Explain, please. In what way are circumstances making it so that only people with certain traits survive to breed. If that isn't so, then we aren't evolving.
Any genetic drift is evolution. There is constant change, it might not be significant and it might not be directed but change is still change. There is no such thing as "Devolving" either, that's simply evolution in a different direction.
It's not just genetic drift of course. Our medecine is not omnipotent, so everyone who dies because it wasn't good enough, well, are submitted to NATURAL selection. There are diseases we can't cure, there are bad doctors, there are people who are allergic to some medicine, and of course there are people who don't have access to any of it.
Most of Africa is a good exemple of natural selection, especially with the AIDS-immune people that pop up now, as are some parts of Asia and South America, and Australia, and even some parts of Europe and North America.
We're very far from not being subjected to Natural Selection.
And of course, there's the natural selection we created for the comfy upper class: the more charismatic/smart you are, the most well paid you are. Some of it at least is genetic, so it works. Funnily enough, on a huge scale, people who live well tend to have fewer kids, so we could say that smart/charismatic people are actually disappearing from the gene pool, eh.
But let's stop the example here.
