I think like almost everything in evolution, the old forms persist. New forms come along - not always, of course; there are species and whole lineages that go extinct - but basically novels and plays, and so on, will continue to exist. Jokes, as the lowest-cost form of narrative, will certainly continue to exist. They're a bit like microbes in the biological world. They're low-cost and they're everywhere. They're the most successful form of life, even though they're not the ones we think about most.

Any artist who really engages with the problems in their medium at that moment and tries to deepen the problems is likely to discover new problems, new possibilities that will excite audiences and continue to excite them.

Social media is your opportunity to reach a massive number of people with transparency, honesty, and integrity.

There is behavioral ecology, which looks closely at the difference different ecologies make to behavior and other features of animals and humans. There's evolutionary individual psychology, there's evolutionary social psychology. In Darwin's terms, evolution couldn't exist without variation, and variation is important in behavioral genetics. And so on, and so on. There are so many instances in which evolution actually sharpens the precision, I think, with which one can find out the importance of differences. We're interested in differences as well as commonalities.

It seems to me to make as much sense to talk about literature as a large-scale human phenomenon without bringing in evolution as it does to engage in cosmology while you're thinking the universe is still geocentric.

Everything is humanities. The sciences are a form of the humanities. They involve traditions of inquiry; they involve social engagement with ideas. They do not happen with a naked brain going out and encountering a nonhuman world. And the better we understand ourselves, the better we can do science, as well. So I don't see them - the sciences and the humanities - as being at all different.

In fiction the story lives the more everyone comes to life, the more each character seems to exist in his or her own right.
