ResumenDomestic donkey (Equus asinus) arose in Africa ~5000 years ago. In modern populations, Equus asinus mitochondrial diversity displays two main haplogroups (Clades 1 & 2). These clades represent two separate maternal origins from North African wild populations; one of Nubian origin (Equus africanus africanus) and other from relatives to Somali wild asses (Equus africanus somaliensis). It has been suggested that Phoenicians introduced the domestic donkey to the Iberian Peninsula during 8th‐7th centuries BC. Thus, the modern Iberian domestic donkeys would be the descendents of these allochthonous animals. In order to test the number of Clades present in Iberia in ancient times, we have analysed Equus asinus mitochondrial DNA from samples associated to the beginning of 4th century BC and recovered from Cancho Roano sanctuary (Zalamea de la Serena, Badajoz). Four teeth were analysed, with morphological characters indicating an ass‐like equid, and representing, at least, two different individuals. A sample from each individual was 14C dated, yielding both the same chronology, 2460 ± 40 years BP. We carried out DNA extraction, nucleotide positions 15439‐15837 from the mitochondrial DNA control region. Haplotypes appeared in Clades 1 & 2, close or identical to historical Nubian wild ass (Equus africanus africanus) and different to Somali wild ass (Equus africanus somaliensis). These results show that both clades were already present in early descendants of those domestic donkeys introduced by the Phoenicians to Iberia.
