Living organism were classified into five kingdoms in the second half of the 20th century.
Prokaryotes were place in one kingdom and eukaryotes in four kingdoms.
When the DNA was compared, two very different groups of prokaryotes were identified, a higher grade of taxonomic group was needed to reflect this, now called a domain
Archaea Eubacteria EukaryotaEvolved from the earliest cells
The “modern” prokaryotes
Consists of all eukaryotes (cells with a nucleus
Inhabit only very extreme environments
Over 10,000 species
