Some organisms, which were previously characterized together, were determined to be genetically very different
|
|
|
The old system of classification was wrong and needed to be corrected
|
|
|
New species are evolving too quickly to keep up with the old system of classification
|
|
|
Domains have always been included, they were just made official recently

Detailed explanation-1: -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.
Detailed explanation-2: -3 types of evidence are: Differences within the sequences of nucleotides within the cell’s ribosomal RNAs (rRNA). The cell’s membrane lipid structure. Its sensitivity to antibiotics.
Detailed explanation-3: -Ultimately, Carl Woese wasn’t completely satisfied with the six kingdoms of classification. So, he decided to create a new taxon called domain. He created a domain to show the similarities and differences between the eukaryotes and bacteria (archaebacteria and eubacteria).
Detailed explanation-4: -The Three Domain system is based on modern molecular evidence, and uses the category Domain as a Superkingdom to emphasize the extremely ancient lineages that exist among prokaryotes and protista, and the relatively recent relationships of multicellular organisms.
