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.

I think that's an important part of art in general. Especially in literature, in stories, we play with eventualities that may put us through a lot of intense negative feelings - say, in horror films or tragedies as intense as King Lear - but we come out feeling richer. We've lived to the fullest, we've tested ourselves in these environments.

Literature and the other arts play with pattern - our brains understand our world by recognizing patterns - and with possibility. The arts harness our sharpest senses, sight and sound, and our richest ways of understanding, in language and narrative. They were our first schools before schools were ever invented. They develop our imaginations, extend our possibilities, and deepen what we can all share.

I would be very surprised if on another planet we discovered a species as intelligent as humans that didn't have narrative, or didn't have art in general.

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.

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.
