The paradigm of Language Dynamics is still little known to dialectologists and language classification specialists. The aim of this article is to show how an approach in terms of the Theory of Complex Adaptive Dynamical Systems (CADS) can be of great benefit to the theories and methods of dialect classification. The principles, methods and tools of both qualitative dialectology (isoglosses, ethnolinguistic areas) and quantitative dialectology (cladistics and editing distance) are applied here to Occitan and Mazatec (Otomangue) in order to validate the uniformity (universality) of the complexionist method in terms of Critical Language Taxonomy (CTL).
