La ansiedad metodológica como búsqueda de objetividad: la construcción de filogenias moleculares

Edna Suárez, Víctor Hugo Anaya

Resumen


“Methodological anxiety” as searching for objectivity: the construction of molecular phylogenies

Starting on the second half of the 1960’s, a lasting discussion on the advantages of molecular over morphological characters in the constructruction of phylogenies has taken place. This discussion gave way to what we have characterized as a methodological anxiety that has guided the ongoing search for more objective methods and representations in the field. The aforementioned search is embodied in the form or normative principles that include the quantification of evidence, the use of statistical inference tools, the commitment to make explicit the criteria used during its evaluation and the automatization of tools using computers, data bases and the advances in bioinformatics. The practices of objectivity in this field are highly contextualized.

 

Key words: Objectivity, subjectivity, molecular phylogenies, quantification, automatization, methodological problems, evolutionary patterns, classification, statistical inference, evidence evaluation.
