  • Currently these archaea could not be cultivated in the laboratory, only the genomes of these organisms could be assembled from the metagenomic sequences. (uni-ulm.de)
  • initially
  • Initially people thought that archaea are 'freaks' living only at sites with extreme living conditions like f.i. hot geysers in Yellowstone National Park and Black Smokers at the bottom of the ocean. (uni-ulm.de)

  • organisms
  • Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. (wikipedia.org)
  • The word archaea comes from the Ancient Greek ἀρχαῖα, meaning "ancient things", as the first representatives of the domain Archaea were methanogens and it was assumed that their metabolism reflected Earth's primitive atmosphere and the organisms' antiquity. (wikipedia.org)
