Cladistics is the hierarchical classification of species based
on evolutionary ancestry. Cladistics is distinguished from other
taxonomic classification systems because it focuses on evolution
(rather than focusing on similarities between species), and
because it places heavy emphasis on objective, quantitative
analysis. Cladistics generates diagrams called cladograms that
represent the evolutionary tree of life. DNA and RNA sequencing
data are used in many important cladistic efforts. Computer
programs are widely used in cladistics, due to the highly
complex nature of cladogram
