I'm sorry, Satch. I didn't quite get your point. What do you mean by adaptation vs. natural selection?

Our environment is changing very fast because of technological achievement so that affects human evolution to some degree. Perhaps the invention of the computer has made it a tiny bit better to be smart and a little less important to be socially intelligent. Who knows? The driving force behind human evolution is still essentially who gets laid and who don't. Any preference doesn't have to be big. If there are two versions of a specific gene and having one version makes you 1% more likely to be chosen as a sexual partner, over the course of a million years, that 1% can make a huge difference in the human gene pool. Of course, sometime during that million years, environment could also change so that it favours the other version of the gene.

In the end, evolution generally operates on a large timescale and it's not something people should concern themselves with. To care about that sort of thing instead of just letting it unfold naturally leads to eugenics and thoughts of human breeding and so on.
