Detailed explanation-1: -In biological taxonomy, a domain (/dəˈmeɪn/ or /doʊˈmeɪn/) (Latin: regio), also dominion, superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. It was introduced in the three-domain system of taxonomy devised by Carl Woese, Otto Kandler and Mark Wheelis in 1990.

Detailed explanation-2: -Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eucarya.

Detailed explanation-3: -The three-domain system is a biological classification introduced by Carl Woese, Otto Kandler, and Mark Wheelis in 1990 that divides cellular life forms into three domains, namely Archaea, Bacteria, and Eukaryota or Eukarya.

Detailed explanation-4: -Some common synonyms of peak are acme, apex, climax, culmination, pinnacle, and summit. While all these words mean “the highest point attained or attainable, ” peak suggests the highest among other high points.

Detailed explanation-5: -Because of Woese’s work, it is now widely agreed that there are three primary divisions of living systems – the Eukarya, Bacteria, and Archaea, a classification scheme that Woese proposed in 1990.
