Talk:Archaea
From Wikispecies
wait, isn't archaea a prokaryote? 69.195.36.86 00:57, 5 Jan 2005 (UTC)
Well, according to the current wikipedia article for prokaryote that classification is still only a recommendation.
However, Woese Carl Woese has proposed dividing prokaryotes into the Bacteria and Archaea (originally Eubacteria and Archaebacteria) because of the significant genetic differences between the two. This controversial arrangement of Eukaryote, Bacteria, and Archaea is called the three-domain system. 67.120.102.12 04:32, 19 Feb 2005 (UTC)
- It's distressing to see incorrect information on my very first click here. Archaea are NOT all extremophiles, only some of them. Lame. 128.172.67.49 19:11, 7 November 2005 (UTC)
- You are very welcome to edit the information you are talking about, so that it reflects the state-of-the-art on Archaea.. - Lycaon 19:58, 7 November 2005 (UTC)
[edit] explanation for wikipedia
[edit] Description
Archaea (singular: archaeon) are single-celled organisms commonly found in a variety of habitats that most biologists previously thought to be uninhabitable, such as boiling hot springs or extremely acidic/salty environments. Archae or other bacteria living in these environments are commonly referred to as extremophiles. Archaea are commonly confused as being a subset of prokaryotes[1], but mRNA[2] sequences reveal that they are a domain in their own right, being distinct from both prokaryotes and eukaryotes[3] but also sharing traits with both. The Domain Archaea include the clades of Euryarchaeota, Crenarchaeota, Nanoarchaeota, and Korarchaeotes, which inhabit such unique niches as halophiles[4], thermophiles[5], and methanogens[6].
[edit] Thermophiles
Regarding this change, which I reverted, the Extremophile page suggests Thermophiles is a descriptive label based on niche, not a taxonomic classification --Georgeryp 14:33, 11 May 2007 (UTC)
