Summary:Systematics as a part of Biology has been through changes on concepts and methods during its history. Here I briefly resume this history and show the principal concepts for phylogenetic systematics as well as a study case including data from the snake genus Conopsis that indicate advantages and disadvantages of using morphological and molecular characters, as well as the analysis of separate or combined data and the taxonomic consequences derived from the results. La sistemática es una disciplina de la biología que a lo largo de su historia ha pasado por cambios fundamentales en sus conceptos y métodos. Este trabajo resume brevemente su historia, además de mostrar algunos de los conceptos fundamentales para realizar sistemática filogenética. Se presenta un estudio de caso realizado con las culebras del género Conopsis para ilustrar las ventajas y desventajas de usar caracteres morfológicos y moleculares, así como de analizar los conjuntos de caracteres por separado y combinándolos.
