DOMAINS OF LIFE
only discovered in 1996
 This is the HIGHEST taxonomic level.
 three domains that showed extreme differences
in their genetic makeup ∴ they were not related
in an evolutionary context


eubacteria
very small single cells organisms
 cells do not contain membrane bound organelle


archaea
very small single cells organisms
 cells do not contain membrane bound organelle


eukaryotes
very diverse in size and complexity
 cells contain membrane bound organelles
