      Salazar, Camilo; Jiggins, Chris D; Taylor, Jesse E; Kronforst, Marcus R; Linares, Mauricio
      Background The neotropical butterfly Heliconius heurippa has a hybrid colour pattern, which also contributes to reproductive isolation, making it a likely example of hybrid speciation. Here we used phylogenetic and ...
