Which of these is NOT a branch on the Phylogenetic Tree of Life?

• Eukarya

• Protozoa

• Bacteria

• Archaea

In early taxonomic classification, organisms were classified by:

• phylum

• environment

• genetic code

• morphology

One of the first depictions of taxonomic organization was from the Greek philosopher:
