Cladistics (/ k l ə ˈ d ɪ s t ɪ k s /; from Ancient Greek κλάδος (kládos) 'branch') is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry.The evidence for hypothesized relationships is typically shared derived characteristics (synapomorphies) that are not present in more distant groups . Phylogenetic systematics became popul ar after Hennig's work on theoretical taxonomy (Hennig, 1950) was translated into English in 1966 (Dupuis, 1984).
