Regarding Humour

I had a thought about humour the other day. As you may or may not be aware, the whole human sense of humour is, evolutionarily, very, very weird indeed and largely defies exact explanation. Attempts at defining the reasons for humour are generally either incomplete or impenetrable. Not to claim that I have made the ultimate insight, of course, but I did come up with something that sort of explains why we find what we find funny, funny. The theory goes as follows:

Along with our unique higher reasoning functions, we developed humour as a coping mechanism for the incongruities, paradoxes, difficulties and outright bizzarreness that the new perspective allowed us to experience. A sense of humour is the by-product of this protection against the mental damage the callous viscissitudes of life would undoubtedly inflict on those intelligent enough to appreciate it.

Or in short; we have to laugh at the weirdnesses of the world to avoid being crushed by it, and finding jokes funny is a by-product of that system, scaled down. Put like that, it's not such an outlandish thought. I have to wonder what the exact mechanism for that development would be, as we progressed from flint-whittling semi apes to well, far more advanced tool users with slightly more advanced social systems (another aspect of humanity I intend to address at some point). Anyway, I like the idea that the enormous amounts of effort poured into creating comedy are merely aimed at satisfying an offshoot of our inbuilt methods for psychic survival.
