Abstract

Together with the Neolithic human expansions, cattle spread from domestication centres and colonized the world. During their tangled expansion dynamics, European cattle occasionally intermingled with local aurochs leading to an exclusive pattern of genetic diversity. Among the most ancient European cattle, are breeds belonging to the so-called Podolian trunk which their history is still not well established. Here we used genome-wide SNP data of 806 individuals belonging to 36 breeds to reconstruct the origin and diversification of the Podolian cattle and to provide a reliable scenario of the European colonization, through an Approximate Bayesian Computation approach. Our results indicate that European Podolian cattle displays higher values of all genetic diversity indices when compared to both African taurine and Asian indicine. All our clustering analyses show close genomic relationships among Podolian breeds suggesting their possible common genetic ancestry. When we simulated and tested scenarios of colonization, we found that Podolian cattle followed different colonization routes, in line with two principal human migrations: via the Danube during the early stages of the Neolithic farmer expansions and through sea routes likely during the pre-Etruscan period. Furthermore, the best fitting model indicates that these two genomic pools admixed in Italy suggesting the Peninsula as an important hub for the Podolian cattle.
