Single celled organisms (unicellular organisms) include all archaebacteria and bacteria and some fungi (like yeasts) and some protists (like single-celled algae and protozoa). None of these organisms have a backbone, where 'backbone' is synonymous with 'spine' or 'vertebral column'. The concept of a backbone or spine or vertebral column is delimited to the realm of vertebrates (mammals, birds, reptiles, amphibians and fish). No unicellular organism can possibly have a backbone.
