|
The old system was always wrong and needed to be corrected

Domains were always there, they just became official

Detailed explanation-1: -According to the six-kingdom classification, organisms can be classified into three domains-Archaea, Bacteria, and Eukarya. These domains are further classified into six kingdoms-Monera or Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia.
Detailed explanation-2: -Under this system, there are three domains-domain Bacteria (corresponding to domain Eubacteria), domain Archaea (corresponding to kingdom Archaebacteria), and domain Eukarya (corresponding to kingdoms Fungi, Plantae, Animalia, and kingdom “Protista”).
Detailed explanation-3: -There are five kingdoms; monera, protista, fungi, plantae and animalia. On the other hand, all living organisms belong to three domains namely, bacteria, archaea and eukarya. Similarly, domain Eukarya includes protista, fungi, plantae and animalia. Hence, this is the difference between kingdom and domain.
Detailed explanation-4: -Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), the cell’s membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.
