I was fascinated to discover, in the transcript of an old Yorkshire Television program from 1973, that Richard Feynman believed the laws of physics might turn out to be the result of an evolutionary process:

"It's as though we were doing the chess game again, and we're working on the rules... But we're not worrying about how the pieces are supposed to be set up on the board in the first place. That's not our business. That's the business of History: how the world evolved. Astronomical history, history of cosmology, how the universe exploded, or the steady state, or whatever it was. It's not our business!

It's interesting that, in many other sciences, there's a historical question. Like in geology: the question, "how did the Earth evolve to the present condition?" In biology, "how did the various species evolve, to get to be the way they are?"

But the one field which has not admitted any evolutionary question is physics. "Here are the laws!" we say. "Here are the laws! Today!" How did they get that way, in time – we don't even think of it that way. We think, well that is that way for forever. It's always been like that, the same laws. And we try to explain the universe that way. So it might turn out that they're not the same all the time, and that there is an historical evolutionary question."
