AB Genetic diversity is lost in small and isolated populations, affecting manyglobally declining species. Interspecific admixture events can increasegenetic variation in the recipient species’ gene pool, but empirical examplesof species-wide restoration of genetic diversity by admixture are lacking.Here we present multi-fold coverage genomic data from three ancientIberian lynx (Lynx pardinus) approximately 2,000–4,000 years old andshow a continuous or recurrent process of interspecies admixture withthe Eurasian lynx (Lynx lynx) that increased modern Iberian lynx geneticdiversity above that occurring millennia ago despite its recent demographicdecline. Our results add to the accumulating evidence for naturaladmixture and introgression among closely related species and show thatthis can result in an increase of species-wide genetic diversity in highlygenetically eroded species. The strict avoidance of interspecific sources incurrent genetic restoration measures needs to be carefully reconsidered,particularly in cases where no conspecific source population exists.
