It would seem that evolution is impossible now that the ability to reproduce is essentially universally available. And depending on how it might be applied, culture and technology could either isolate some people from others, or it could help to renormalize them to the rest. Evolution is defined as a change in gene frequencies over time, which means that over generations, there will be changes in the gene pool, and humans experience those changes as much as any other organism.
Some people live and some people die, and some people pass on more genes than others.
Therefore, there is a change in the human gene pool over time. But we might suggest that with all that cultural and technological intervention that there would be some kind of influence in the composition of the gene pool, and there is. Take smallpox, for an example. Years ago millions of people died from smallpox, and their genes were not passed on because many of them died before reproductive age. The human gene pool was then missing the genes of those people.
