Mitochondrial DNA sequences and restriction fragment polymorphisms were retrieved from three Islamic 12th–13th century samples of 71 bones and teeth (with >85% efficiency) from Madinat Baguh (today called Priego de Cordoba, Spain). Compared with 108 saliva samples from the present population of the same area, the medieval samples show a higher proportion of sub-Saharan African lineages that can only partially be attributed to the historic Muslim occupation. In fact, the unique sharing of transition 16175, in L1b lineages, with Europeans, instead of Africans, suggests a more ancient arrival to Europe from Africa. The present day Priego sample is more similar to the current south Iberian population than to the medieval sample from the same area. The increased gene flow in modern times could be the main cause of this difference. Am J Phys Anthropol 2006. © 2006 Wiley-Liss, Inc.
