Biologists have always
- rganized all living
- rganisms into large
groups called Kingdoms.
For many years,
Scientists recognized two forms of life,
Prokaryotes Eukaryotes.

Eukaryote is an
- rganism that
have cells with nuclei, or nucleus
Prokaryote is an
- rganism without
a nucleus.

Today, Biologists
group organisms into six kingdoms, based on their similarities
Eubacteria and
Arachaebacteria were once grouped in the kingdom Monera, which contained all the Prokaryotes.

SLIDE 6
Today after the
advances in Bio- Technology, Scientists have gathered data from RNA and DNA Sequencing
Monerans have now
been divided into two distinct Kingdoms
Eubacteria Archaebacteria

For many years
Scientists recognized two basic forms of life,
Prokaryotes Eukaryotes.
In 1977, Carl Woese and
his colleagues proposed that some prokaryotes are so difgerent from
- thers that they needed
to be divided into their
- wn broad division.

Woese and his
colleagues based their proposal on comparisons of ribosomal RNA sequences.
They concluded that
the prokaryotes that make up the kingdom Archaebacteria are more closely related to Eukaryotes than they are to the other Kingdom of Prokaryotes, Eubacteria.

In 1996, Scientists made the first
comparison between the DNA sequences
- f Archaebacterium and a Bacterium.
In light of the past difgerences between
the two groups of prokaryotes, biologists have adopted a classification system that divides all organism into three super kingdoms or domains:
Bacteria Archae Eukarya

The oldest of course is Bacteria. This is followed by the
Archaebactera and then Domain Eukarya which includes the other Four Kingdoms:
Protista Fungi Plantae Animalia
