Combined with the five-kingdom model, this created a six-kingdom model, where the kingdom Monera is replaced by the kingdoms Bacteria and Archaea. [16] This six-kingdom model is commonly used in recent US high school biology textbooks, but has received criticism for compromising the current scientific consensus. [ 13 ]
Carl Linnaeus made the classification "domain" popular in the famous taxonomy system he created in the middle of the eighteenth century. This system was further improved by the studies of Charles Darwin later on but could not classify bacteria easily, as they have very few observable features to compare to the other domains.
The four kingdoms: In Daniel 2 Nebuchadnezzar dreams of a giant statue of four metals identified as symbolising kingdoms, and in Daniel 7 Daniel sees a vision of four beasts from the sea, again identified as kingdoms. In Daniel 8, in keeping with the theme by which kings and kingdoms are symbolised by "horns", Daniel sees a goat with a single ...
] Linnaeus used this as the top rank, dividing the physical world into the vegetable, animal and mineral kingdoms. As advances in microscopy made the classification of microorganisms possible, the number of kingdoms increased, five- and six-kingdom systems being the most common. Domains are a relatively new grouping.
The three-domain system adds a level of classification (the domains) "above" the kingdoms present in the previously used five- or six-kingdom systems.This classification system recognizes the fundamental divide between the two prokaryotic groups, insofar as Archaea appear to be more closely related to eukaryotes than they are to other prokaryotes – bacteria-like organisms with no cell nucleus.

Kingdom monera. They belong to the prokaryote characteristics of kingdom monere. they are unicellular organism. they show different mode of nutrition such as autotrophic, heterotrophic,parasitic; they lack mitochondria; they have few organelles which are not membrane bounds; flagellum serves as the locomotory organ; reproduction is both sexual ...
