Until the late 1970s,there was no "Domain" of scientific naming as the broadest category in taxonomy.Kingdom Monera included similar microscopic organisms of Eubacteria and Archebacteria.Other kingdoms,Protista,Plantae,Fungi and Animalia were also named.Researchers proposed the Domain to account for distinction beyond existing differences discovered between the bacteria-like organisms.Which type of information led most directly to the support and adoption of the broader category of Domain,and subsequent Domains of Bacteria,Archaea and Eukarya?

Differences in DNA among the existing Kingdoms showed the need for a broader naming category. As researchers studied the organisms more closely, they found that the differences in DNA were significant enough to warrant the creation of a new broader category, which became known as the Domain. This led to the recognition of the three Domains of Bacteria, Archaea and Eukarya, which better reflected the evolutionary relationships between organisms.
