Monera

From Free net encyclopedia

Image:PhylogeneticTree.jpg Monera is a biological kingdom or domain, comprising most living things with a prokaryotic cell organization. For this reason the kingdom is sometimes called Prokaryotae. Prior to its creation these were treated as two separate divisions of plants: the Schizomycetes or bacteria, considered fungi, and the Cyanophyta or blue-green algae. The latter are now considered a group of bacteria, typically called the cyanobacteria, and are known not to be closely related to plants, fungi, or animals.

Studies by Woese in 1977 showed the prokaryotes are divided into two separate groups, which do not appear nearer relatives than they are to the eukaryotes. These were called the Eubacteria and Archaebacteria, and later the Bacteria and Archaea. They may be treated as subkingdoms, but most newer schemes tend to abandon the Moneran and treat these as separate domains.

Ernst Haeckel proposed the Moneran in the 1880s. He found out that there are many fundamental characteristics rarely seen in other organisms but found in bacteria and blue-green algae. Do not confuse Moneran with Protista, a different (eukaryotic) taxon proposed by Haeckel in the 1860s. Originally, Haeckel's protists were conceived as including the prokaryotes, but he proposed the Moneran after coming to understand the fundamental differences between prokaryotes and eukaryotes. There are no eukaryotic monerans.
