Hello, I have a question based on Taxonomy, or, the arrangement/organization of living things. My question is based on the highest Taxa, the Domain. My question is: The three domains, Archaea, Bacteria, and Eukarya, are set. However, I often hear Archaea interchanged with the word "Archaeabacteria", and Bacteria interchanged with the word "Eubacteria". So according to the individuals using such words, the three Domains can be called Eukarya, Archeabacteria, and Eubacteria. Would this not be contradictory? Calling the two Prokaryotic domains "Archeabacteria" and "Eubacteria" would suggest that both domains are a type of Bacteria, but is that really the case? Are they right to call the domains by those names? Or are Archaea and Bacteria two entirely different entities? I suppose in a sense, I am asking, are Archaea a type of bacteria, or a completely different entity altogether? Because in that case, Archaea should not have their name used interchangeably with the word "Archaeabacteria".
