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 was a method of classifying living organisms into two kingdoms - vegetabilia (plants and fungi) and animalia (animals). It was established by Linnaeus in 1735.
Archaea and Bacteria.
One characteristic used to place organisms into kingdoms is
Plant and animal kingdoms
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.
