The phylogenetic and hybridization history of Xiphophorus fish remains contentious, despite their long-standing role as models in evolutionary biology and human disease research. This study presents a complete genome resource that resolves the previously conflicting phylogeny and evolutionary history of the group, revealing that hybridizations preceded speciation.
