I didn’t say anything about natural selection, I said evolution. Humans evolve by more means than natural selection. We also evolve through culture, through technology. And of course we still do evolve by natural selection, it’s just hard to see because the pace of technology is so rapid.

Take birth control as an example. It’s very recent technology. A blink of an eye in natural selection terms. You might think it would wipe us out by causing population crashes. But culture is evolving to counteract it. Cultural norms have already begun to shift heavily against birth control. I think it’s fairly easy to anticipate a future where birth control is not used very much.
