archaebacteria and eubacteria
The original first two kingdoms were animals and plants.
Carl Woese split up the prokaryotes into two kingdoms, creating a total of six kingdoms.
The two kingdom classification system is an older system that categorizes organisms into two kingdoms: Plantae and Animalia. This system is based on the presence or absence of cell walls and the ability to perform photosynthesis. It has limitations due to the exclusion of other important groups of organisms, leading to the development of more advanced classification systems with multiple kingdoms.
Archaea and Bacteria.
The more classification levels two organisms share, the more closely related they are in terms of evolutionary history. Organisms that share many classification levels are likely to be more similar in terms of genetics, anatomy, and behavior.
The kingdoms included in both Linnaean and Whittaker systems of classification are Animalia, Plantae, Fungi, Protista, and Monera (or Prokaryotae in the Linnaean system).
bacteria;archae and euba
Lately scientists have found many species that they are not sure what to classification as because really they could be either, so they have the options to make more in-between kingdoms, or to just classificate them as living and nonliving organisms
In the actual taxonomical classification, only 5 taxa are recognized at level of kingdoms; there's no need to have a new different one.
Actually, there are more than two 'kingdoms' in modern biological classification. Modern biologists recognize three 'domains' of life: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are prokaryotes.
