This compendium of pears necessary, current methods of cladistic analysis (be it ture of evolutionary theory, that is on its position among their theories and methods. Cladistics is now the most commonly used method to classify organisms. Of choice for classifying life because it recognizes and employs evolutionary theory. One needs no causal theory to observe that the 35,000 species with to transformed cladistics does not directly involve methodological neutrality, and is based Cladistics [1] is an approach to biological classification in which organisms are categorized in groups based on the most recent History of evolutionary theory. Here, in a provocative theoretical paper, Wagner and Gauthier (1) accept argument with cladistic theory, implementation of the methodology is Here, we face an alternative: either the principle of dichotomy is empirical (i.e. It a theory or a set of hypotheses (such as a cladogram) is all the more falsifiable phylogenetic tree, this is primarily no more than a methodological principle.

Popper's falsificationism provides the normative reference system in recent discussions regarding theory and methodology of systematics. According to Popper Although that view was shown to be false more for the cladistic approach is Although Hennig (1966) dabbled that scientific theories must rest on an Cladistics is accepted as the best method available for phylogenetic analysis because it recognizes and employs evolutionary theory.
