Evolutionary Origins of Extreme Halophilic Archaeal Lineages

WebDomain Archaea contains 4 4 major groups. Intriguingly, so far, no archaea that are human pathogens have yet been discovered. Archaea do live in our bodies and those of animals—for instance, in the gut—but all of them seem to be harmless or beneficial. WebArchaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), ... However, in other phylogenetic analyses it was found that DPANN does not form a monophyletic group and that it is caused by the long branch attraction (LBA), suggesting that all these lineages belong to "Euryarchaeota".

For much of the 20th century, prokaryotes were regarded as a single group of organisms and classified based on their biochemistry, morphology and metabolism.
