Archaea were first classified as a separate group of prokaryotes in 1977 by Carl Woese and George E. Fox in phylogenetic trees based on the sequences of ribosomal RNA (rRNA) genes. These two groups were originally named the Archaebacteria and Eubacteria and treated as kingdoms or subkingdoms, which Woese and Fox termed Urkingdoms. Woese argued that this group of prokaryotes is a fundamentally different sort of life. To emphasize this difference, these two domains were later renamed Archaea and Bacteria. The word archaea comes from the Ancient Greek ἀρχαῖα, meaning "ancient things".

Is bacteriophage in the domain archaea?
No, bacteriophages are viruses that infect bacteria, not archaea. Archaea are a separate domain of single-celled microorganisms that are distinct from both bacteria and viruses.
Why are members of this domain called archaea?
Members of the domain Archaea are called archaea because they were initially mistaken for bacteria due to their small size and simple structure. When they were discovered to be a distinct group of organisms with unique characteristics, they were given the name Archaea, derived from the Greek word "archaios" meaning ancient, to reflect their ancient origins in evolutionary history.
Why are members of this domain called archaea which comes form the Greek word that means ancient?
Members of the domain Archaea are called "archaea" because they were initially thought to be ancient and primitive organisms that resemble the earliest forms of life on Earth. They were given this name as a reflection of their perceived evolutionary significance as ancient organisms that have persisted through time.

Euryarchaeota is a kingdom of Archaea. Its domain is Archaea.
Do both domain bacteria and domain archaea have a nucleus?
Both archea and bacteria are prokaryotic, meaning they have no nucleus.
How are the organism in the domain eukarya different from those in domain archaea?
Eukaryotes have a nucleus, Archaea do not.
How are organisms in the domain eukarya different from thoses in the domain archaea?

How are organisms in the domain archaea different from thoses in the domain eukarya?
Eukaryotes have a nucleus, Archaea do not.
Which domain is directly related to the oldest organism on earth?
The domain Archaea covers the organisms considered to be the oldest on earth.They are commonly called archaebacteria but they are quite different from bacteria and are now more properly called archaea.
To what domain does bacteria belong?
The eubacteria (true bacteria) is an older classification, now just called bacteria, which is the domain itself. The other domain of prokaryotes is now called archaea.
What is the common scientific name for domain archaea?
Firstly, there is no such thing as a 'common scientific name'; that is a contradiction, containing two opposites. The scientific name for the Archaea is Archaea.

Is bacteriophage in the domain archaea?
No, bacteriophages are viruses that infect bacteria, not archaea. Archaea are a separate domain of single-celled microorganisms that are distinct from both bacteria and viruses.
