The Value of Being Smart

Linguistic intelligence has only evolved once and didn't evolve until the world had been around for more than four billion years. I was just wondering if farm animals, when they're just chew in their cud, if they have theories of the universe that they're thinking about. So I'd like to think so. Tell ourselves that being smart gives us an advantage. Where I'm thinking, if being smart gave you an advantage, there'd be many more other what we would think of as smart animals in the tree of life. In apocalyptic earth, we're extinct. A whole lot of other animals will rise up in our place and no one ever accused them of being smart.
