The three domain system is used to classify biological microorganisms. The three domain system among other benefits creates a method for comparing cells, shows the order in life and provides a better classifying system that is in line with current evolutionary research.
In a three-domain system, protists belong to the domain Eukarya along with plants, animals, and fungi. Protists are eukaryotic organisms that are diverse in terms of their characteristics and lifestyles, ranging from unicellular to multicellular forms.
The three-domain system of classification made the traditional kingdom Monera obsolete. Monera used to include all prokaryotic organisms, but with the advent of the three-domain system, prokaryotes were split into two separate domains: Bacteria and Archaea.
The newest classification system with the highest rank of domain followed by kingdom is the three-domain system, which categorizes organisms into the domains Bacteria, Archaea, and Eukarya.
The three domain classification is based on differences in cellular structures, specifically the presence of a membrane-bound nucleus in the domain Eukarya, as compared to bacteria (domain Bacteria) and archaea (domain Archaea) that lack this feature. This system reflects the evolutionary relationships among these three groups of organisms.
The three-domain system of classification arose in the 1990s, based on molecular data that showed fundamental differences between bacteria, archaea, and eukarya. This system revolutionized our understanding of the diversity of life on Earth.

The domain name system was created in 1983. The staff at the Stanford Research Institute is responsible for its creation.
The three-domain system classifies all known life forms into three domains: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are prokaryotic, while Eukarya includes all eukaryotic organisms. This classification is based on genetic and cellular characteristics, reflecting evolutionary relationships among organisms.
The three-domain system of classification includes Archaea, Bacteria, and Eukarya. Archaea and Bacteria are prokaryotic domains, while Eukarya encompasses all eukaryotic organisms. This system reflects genetic and evolutionary differences among organisms based on molecular data.
Karatsu Domain was created in 1593.
