Is intelligence is a basic feature of life? What do we mean when we speak or write about intelligence? There are at least a few working definitions, one is humans know it when they encounter it, as in the Turing test. Another is that human intelligence marks the top of a scale of animal intelligence. Casual language about intelligence usually confuses it with smartness, and is a competitive notion.
I wonder if intelligence is not a more profound aspect of all life, present in every living organism and at every scale. We may find a more useful idea of intelligence if we give intelligence some wiggle-room. I also wonder if intelligence is a fundamental property of life. Could any organism function without some level of intelligent or orderly information transfer and exchange within it's boundaries? Isn't information transfer and exchange a basic operation within intelligence? Perhaps an organelle or a virus does not aspire to the label highly intelligent, but it gets it's own job done.
