Iberia has been proposed as a potential domestication centre and is renowned for producing world-class bloodlines. Here, we generate genome-wide sequence data from 87 ancient horse specimens (median coverage = 0.97X) from Iberia and the broader Mediterranean to reconstruct their genetic history over the last ~26,000 years. Here, we report that wild horses of the divergent IBE lineage inhabited Iberia from the Late Pleistocene, while domesticated DOM2 horses, native from the Pontic-Caspian steppes, already arrived ~1850 BCE. Admixture dating suggests breeding practices involving continued wild restocking until at least ~350 BCE, with IBE disappearing shortly after. Patterns of genetic affinity highlight the far-reaching influence of Iberian bloodlines across Europe and north Africa during the Iron Age and Antiquity, with continued impact extending thereafter, particularly during the colonization of the Americas. info:eu-repo/grantAgreement/ES/MCINN-FEDER/PID2020-113369RJ-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tressières, Gaétan Chauvey, Lorelei Schiavinato, Stéphanie Calvière-Tonasso, Laure Seguin-Orlando, Andaine Southon, John Shapiro, Beth Bataille, Clément Birgel, Julie Wagner, Stefanie Khan, Naveed Liu, Xuexue Rodanés, José María Universidad de Zaragoza (orcid)0000-0001-9644-4252 Picazo Millán, Jesús V.
