We're certainly evolving in the sense that we're developing both culturally and bioloigically over time. Our life spans change, for example, as does our health, thanks to changes in our diet and in medical technology.

Any story about how we're still being naturally selected, though, would have to compete with a cultural explanation, because we're also self-selecting the outcomes. Natural selection refers mainly to the environment and to the genes as the producers of the eventual phenotype. The organism's self-awareness and intelligence aren't part of that reductive biological explanation because those factors are negligible in most species. But they're clearly not in ours.

I have another article coming out in a week or two on the question of whether we're separate from nature. It's called "How Civilization Devours Nature like a Black Hole: The unnaturalness of our progress in the universal wilderness."
