It&#x27;s arguable that all organisms today are superorganisms. Try to grow a plant in inert soil without bacteria, for example.<p>You probably have to go back 3.5 billion years, to the dawn of life, to find organisms that did not depend on any other organism to grow and&#x2F;or reproduce. And maybe not even then; it&#x27;s possible that early life arrived on Earth from somewhere else, on a meteorite or comet.
