| Abstract: | In the present paper the essentials of the concept and method of quantitative parsimony analysis for cladogram construction are revealed. The parsimony criterion is invoked to choose the preferred cladogram in which the nodal character-state values of any two evolutionary units connected by a Wagner neighborhood either maximize the number of synapomorphies or minmize the number of postulated new character-state changes. The suggestions regarding the application of quantitative parsimony analysis are also discussed. |
