archaebacteria and eubacteria
The original first two kingdoms were animals and plants.
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.
Carolus Linnaeus defined two main kingdoms in his classification studies of living things. For plants he chose Vegetabilia, and for animals he chose Animalia.
Archaea and Bacteria.
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
Carl Woese split up the prokaryotes into two kingdoms, creating a total of six kingdoms.
Aristotle's classification system primarily categorized living organisms into two kingdoms: Animalia (animals) and Plantae (plants). He based this classification on observable characteristics such as habitat, movement, and reproductive methods. While his system laid the groundwork for biological classification, it was later expanded to include more kingdoms as scientific understanding evolved, leading to the modern five and six kingdom systems.
No, in biological classification, Kingdom is a higher level of classification than Domain. Domains represent the highest level of biological classification, which can be further divided into kingdoms.
Aristotle's classification system was mainly focused on plants and animals, the two kingdoms that were most visible and familiar to him. He based his classification on observable physical characteristics and traits, and at the time, these were the most prominent groups of organisms that were recognizable and distinguished easily.

______ was the first person to use a two-kingdom system of classification.
In the actual taxonomical classification, only 5 taxa are recognized at level of kingdoms; there's no need to have a new different one.
