Resumen:
Hybridization is widespread and constitutes an important source of genetic variability and evolution. In animals,
its role in generating novel and independent lineages (hybrid speciation) has been strongly debated, with only a
few cases supported by genomic data. The South American fur seal (SAfs) Arctocephalus australis is a marine
apex predator of Pacific and Atlantic waters, with a disjunct set of populations in Peru and Northern Chile [Peruvian fur seal (Pfs)] with controversial taxonomic status. We demonstrate, using complete genome and reduced
representation sequencing, that the Pfs is a genetically distinct species with an admixed genome that originated
from hybridization between the SAfs and the Galapagos fur seal (Arctocephalus galapagoensis) ~400,000 years
ago. Our results strongly support the origin of Pfs by homoploid hybrid speciation over alternative introgression
scenarios. This study highlights the role of hybridization in promoting species-level biodiversity in large
vertebrates.
