Data from: Genomic data and multi-species demographic modelling uncover past hybridization between currently allopatric freshwater species

Sofia L. Mendes, Miguel P. Machado, Maria M. Coelho & Vitor C. Sousa
Evidence for ancient interspecific gene flow through hybridization has been reported in many animal and plant taxa based on genetic markers. The study of genomic patterns of closely related species with allopatric distributions allows the assessment of the relative importance of vicariant isolating events and past gene flow. Here, we investigated the role of gene flow in the evolutionary history of four closely related freshwater fish species with currently allopatric distributions in western Iberian rivers...
