Comments p.2 left column 2nd paragraph:"Interestingly, there is electron microscopic information for one lineage of nanoarchaea with average cell volumes in the range of 0.009–0.04?µm^3 (primary source). Recent evidence hints at the existence of bacteria in this same size range." Primary source abstract: "Within acid mine drainage biofilms, apparently free-living ARMAN cells from a deeply branched archaeal lineage have volumes of 0.009-0.04µm^3 (mean approximately 0.03+/-0.01 µm^3), only approximately 92 ribosomes, yet are frequent hosts for replicating viruses."
