Taxonomy is one of the branches of science that deals with the study of describing, naming, and classifying all sorts of living organisms and microorganisms that exist here on Earth. Taxonomists name, identify organisms and arrange them into classifications using the morphological, genetic and biochemical observations, and behavioral observations.

In taxonomy, domain is also known as superkingdom, empire, or superregnum. Domain is the highest taxonomic rank of all sorts of organisms. Carl Woese, an American microbiologist and biophysicist, designed the three-domain system which includes: Archea, bacteria and eukatyote.
