Lynn Margulis comments, “Most bacteria have far more important things to do on this Earth than to devour our tissues while we are still alive, drink our blood when we are old and weak, or fight with us over who will eat our food first. . . . Those who hate and want to kill bacteria indulge in self-hatred. Our ultimate ancestors, yours and mine, descended from this group of beings. Not only are bacteria our ancestors, but also . . . as the evolutionary antecedent of the nervous system, they invented consciousness.
