Well in terms of evolution there needs to be a set of instructions that gets passed on. If those instructions can mutate, we have evolution. Perhaps it isn't genetic code that gets passed on, but e.g. cultural inventions. That said, these biological circuits that we are considering get replicated in whatever environment that they exist in. Love may lead to other things than biological reproduction. Our lore regarding the human, personal experience of love and what to do with it also mutates and evolves. A poem then, may take the place of the greatest invention.
