While the presence of a nuclear membrane differentiates the Eukarya from the Archaea and Bacteria, both of which lack a nuclear membrane, distinct biochemical and RNA markers differentiate the Archaea and Bacteria from each other.

It may also be the oldest form of life on Earth! New Models for Prokaryotic Biology.

Halophilesorganisms that thrive in highly salty environments, and hyperthermophilesorganisms that thrive in extremely hot environments, are examples of Archaea. En Caister Academic Press. They characteristically do not have ether linkages like Archaea, and they are grouped into a different category—and hence a different domain.

Archaa which contain an environment wherein archaea might survive include Venusthe past environment of MarsJupiterSaturnand Jupiter’s moon Io. They like the heat so much that it has earned the nickname “thermophile”, which means “loving heat”, and it would probably freeze to death at ordinary room temperature. This model is supported through Article Processing Charges.


Other extremophile Archaea love to live in very salty, called hypersaline, environments. Even though bacteria are prokaryotic cells just like Archaea, their membranes are made of unbranched fatty acid chains attached to glycerol by ester linkages.
