%X Multiple geographical regions have been proposed for the domestication of Equuscaballus. It has been suggested, based on zooarchaeological and genetic analyses that wildhorses from the Iberian Peninsula were involved in the process, and the overrepresentationof mitochondrial D1 cluster in modern Iberian horses supports this suggestion. Totest this hypothesis, we analysed mitochondrial DNA from 22 ancient Iberian horseremains belonging to the Neolithic, the Bronze Age and the Middle Ages, againstpreviously published sequences. Only the medieval Iberian sequence appeared in the D1group. Neolithic and Bronze Age sequences grouped in other clusters, one of which(Lusitano group C) is exclusively represented by modern horses of Iberian origin.Moreover, Bronze Age Iberian sequences displayed the lowest nucleotide diversity valueswhen compared with modern horses, ancient wild horses and other ancient domesticatesusing nonparametric bootstrapping analyses. We conclude that the excessive clustering ofBronze Age horses in the Lusitano group C, the observed nucleotide diversity and the localcontinuity from wild Neolithic Iberian to modern Iberian horses, could be explained bythe use of local wild mares during an early Iberian domestication or restocking event,whereas the D1 group probably was introduced into Iberia in later historical times.
