Taxon

Domain
The highest taxonomic rank of organisms in which there are three groupings: Archaea, Bacteria and Eukarya.
Phylogeny
The evolutionary development of a species or of a taxonomic group of organisms.
Characters
the mental and moral qualities distinctive to an individual.
Molecular clock
technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged.
