Quizplus · Accepted Answer

Archaea were given their own separate domain because they have unique genetic sequences that are distinct from bacteria and eukaryotes, but they share some similarities with eukaryotes that bacteria do not, such as certain aspects of their ribosomal RNA and membrane lipid structure. This genetic evidence suggests they are a distinct form of life, more closely related to eukaryotes than to bacteria, justifying their classification in a separate domain.
