Resumen:
Evolutionary biogeography integrates distributional, phylogenetic, molecular and paleontological data in order to discover biogeographic patterns and assess the historical changes that have shaped them, following a step-wise approach. Although most of the authors involved in the theoretical development of biogeography or that apply specific methods usually conceive them as representing alternative "schools", they can be used to answer different questions. This review introduces the steps of this integrative approach and details the available methods. An evolutionary biogeographical analysis involves five steps: (1) recognition of biotic components (sets of spatio-temporally integrated taxa due to common history), through panbiogeography and methods used to identify areas of endemism; (2) contrastation of the biotic components and identification of the vicariant events that fragmented them, through cladistic biogeography and comparative phylogeography; (3) establishment of a hierarchic arrangement of the components in a biogeographic system of realms, regions, dominions, provinces and districts; (4) identification of cenocrons (sets of taxa with similar origins and ages), dated using intraspecific phylogeography, molecular clocks and fossils; and (5) formulation of a geobiotic scenario, that explains the evolution of the biotic components and cenocrons, integrating geological and tectonical information. © 2010 Nova Science Publishers, Inc.
