The three-domain system is a biological classification introduced by Carl Woese et al. in 1990[1][2] that divides cellular life forms into archaea, bacteria, and eukaryote domains. In particular, it emphasizes the separation of prokaryotes into two groups, originally called Eubacteria (now Bacteria) and Archaebacteria (now Archaea). Woese argued that, on the basis of differences in 16S rRNA genes, these two groups and the eukaryotes each arose separately from an ancestor with poorly developed genetic machinery, often called a progenote. To reflect these primary lines of descent, he treated each as a domain, divided into several different kingdoms. Woese initially used the term "kingdom" to refer to the three primary phylogenic groupings, and this nomenclature was widely used until the term "domain" was adopted in 1990.[2]

∙ 11y agoThe three types are the Eubacteria, also known as just "bacteria", Archaea, and the Eukarya.
The three-domain system of classification groups organisms into the following 3 categories:
# Bacteria # Archaea/archaeabacteria # Eukarya
Bacteria and Archaebacteria are both include unicellular prokaryotes but there are differences between in their genetic material and proteins. Eukarya have a nuclei in their cells and are more complex than the prokaryotes.
