Bacteria - Encyclopedia. com Prokaryotes belong to the kingdom Monera Some scientists have proposed splitting this designation into the kingdoms Eubacteria and Archaebacteria Eubacteria, or true bacteria, consist of more common species , while Archaebacteria (with the prefix archae—meaning ancient) represent strange bacteria that inhabit very hostile environments
Evolutionary Origin of Bacteria and Viruses - Encyclopedia. com Such " extremophiles " are part of the division of life known as the Archae, specifically the archaebacteria Whether bacteria originated in the sea or on land remains a mystery The available evidence, however, supports the origin of bacteria in the sea
Kingdoms of Life - Encyclopedia. com One kingdom, Monera, contains all the prokaryotes , and the other kingdoms contain different groups of eukaryotes However, work done in the 1980s by Carl R Woese of the University of Illinois on the genetic makeup of cells seems to favor a six-kingdom system that divides Monera into two kingdoms, Bacteria (Eubacteria) and Archae (Archaebacteria)
Monerans - Encyclopedia. com Archaebacteria Archaebacteria are unique, since some species live in such harsh places as boiling mud, hot springs, and extremely salty water, while others live in the intestinal tracts of some mammals The archae-bacteria called thermoacidophiles thrive in the recently discovered deep-sea volcanic vents where it is extremely hot Eubacteria
Eubacteria - Encyclopedia. com Eubacteria Bacteria are microscopic organisms that comprise the domain Eubacteria A domain is the highest grouping of organisms, superseding the level of kingdom in the classical Linnaean system of biological classification There are three domains, two of which, Eubacteria and Archaea, are composed entirely of prokaryotic organisms; the third domain, Eucarya, encompasses all other
