     • Domain Definition In biology, a domain refers to the largest of all groups in the classification of life. There are currently 3 agreed groups at this level, the Archaea domain, Bacteria domain, and Eukarya domain. Each domain contains a collection of organisms with similar properties and evolutionary histories, as scientists have organized them.

   What is a domain in biological taxonomy?

   • The concept of domains was officially introduced into the domain of biological taxonomy through the three-domain system, meticulously crafted by Carl Woese, Otto Kandler, and Mark Wheelis in 1990. This innovative system revolutionized our understanding of the diversity of life on Earth by redefining the fundamental units of classification.

   What is a bacterial domain?

   • He defined domain as a taxon higher than the kingdom. In 1990, Woese and his colleagues proposed a new classification system containing three domains: Bacteria, Archaea, and Eukarya. As shown in Figure below, the Bacteria domain was formerly the Eubacteria kingdom, and the Archaea domain was formerly the Archaebacteria kingdom.

   BioSystems, 1984. Because most recent treatments of the protists (‘lower’ eukaryotes comprising the kingdom PROTISTA Haeckel, 1866) have been preoccupied with either a ‘phylogenetic-tree’ approach or a discussion of the impact of possible endosymbiotic origins of major intracellular organelles, the overall systematics of the group, from taxonomic and nomenclatural points of view, has ...

   • Domains. All life on Earth can be characterised into three Domains: Domain Bacteria: this domain comprises of unicellular prokaryotic bacteria. Domain Archaea: this domain comprises of unicellular prokaryotic organisms that are similar to bacteria but are in some ways more related to eukaryotes.
   • Kingdoms. Each Domain can be broken down into different Kingdoms. In Domain Eukarya, there are four major Kingdoms: Kingdom Prokaryotae: is made up of the various prokaryotes, which are unicellular.
   • Phyla. Each Kingdom can be broken down into different Phyla (sing. Phylum). The Kingdom Animalia consists of eleven distinct phyla. Class, Order, Family, Genus, Species.
