The three-domain system is a biological classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to
