Genomes of the Orestias pupfish from the Andean Altiplano shed light on their evolutionary history and phylogenetic relationships within Cyprinodontiformes

Abstract

We generated genome resources for three Orestias species from the Andean Altiplano and used them to reassess the position of this group within Cyprinodontiformes. The analysis shows that Orestias is more closely related to South American lineages than to Cyprinodontidae, and supports Orestiidae as the appropriate family-level placement.
