Plantae due to their ability to photosynthesize. Traditionally the natural world was classified as animal, vegetable, or mineral as in Systema Naturae. After the development of the microscope, attempts were made to fit microscopic organisms into either the plant or animal kingdoms. Ten years after The Origin of Species by Charles Darwin, in 1866 Ernst Haeckel, a supporter of evolution, proposed a three-kingdom system that added the Protista as a new kingdom that contained most microscopic organisms. Bacterium — a genus of rod-shaped bacteria first described in 1828. Haeckel does not explicitly assign this genus to the Monera.
Bacillus — a genus of spore-forming rod-shaped bacteria first described in 1835 Haeckel does not explicitly assign this genus to the Monera kingdom. Spirillum — spiral-shaped bacteria first described in 1832 Haeckel does not explicitly assign this genus to the Monera. Haeckel does provide a comprehensive list. Lepomonera Protomonas — identified to a synonym of Monas, a flagellated protozoan, and not a bacterium. The name was reused in 1984 for an unrelated genus of bacteria. Vampyrella — now classed as a eukaryote and not a bacterium. Like Protista, the Monera classification was not fully followed at first and several different ranks were used and located with animals, plants, protists or fungi.
Furthermore, Häkel’s classification lacked specificity and was not exhaustive — it in fact covers only a few pages—, consequently a lot of confusion arose even to the point that the Monera did not contain bacterial genera and others according to Huxley. The most popular scheme was created in 1859 by C. Von Nägeli who classified non-phototrophic Bacteria as the class Schizomycetes. Desmobacteria for the longer, filamentous rods and Spirobacteria for the spiral forms. Schizophyceae This union of blue green algae and Bacteria was much later followed by Haeckel, who classified the two families in a revised phylum Monera in the Protista.
1941, The main outlines of bacterial classification. The term Monera became well established in the 20s and 30s when to rightfully increase the importance of the difference between species with a nucleus and without, In 1925, Édouard Chatton divided all living organisms into two empires Prokaryotes and Eukaryotes: the Kingdom Monera being the sole member of the Prokaryotes empire. Monera consisting of bacteria, such Copeland in 1938 and Whittaker in 1969. Alternative commonly followed subdivision systems were based on Gram stains. For current subdivision of Bacteria, see Bacterial phyla.
