Already what were thought to be bacteria for generations have been found to compose, instead, two great domains of microorganisms: true bacteria and one-celled organisms the archaea, which are closer than other bacteria to the eukaryota, the group that we belong to.
Već ono što smo generacijama smatrali bakterijama, umjesto toga, otkrili smo, dva su velika svijeta mikroorganizama: prave bakterije i jednostanični organizmi, arheje, koji su bliži eukariotima od ostalih bakterija; skupini kojoj mi pripadamo.
