I managed not to notice this was a month old… oh well.

And useless isn’t necessarily bad, just making the point that art doesn’t serve any particular function – if it was useful for something it’d be a tool, or technology or something like that. Art necessarily has no ‘useful’ purpose.

From an evolutionary perspective, it could be akin to the peamale reproductive organ’s tail – it serves no particular purpose, it is in all likelihood detrimental to survival (time spent on art is time not spent on gathering food), but it’s pretty good for attracting a mate. Being a musician or an artist can get you laid… not so much for the sciences.
