"In fact, the historical evidence for gene flow between Europe and the Near East provides strong grounds for assuming that there is at least some back-migration from Europe across the Bosporus- or, further east, across the Caucasus into the Near East - throughout the past 10,000 years. Candidates include the Philistine migrations from the Aegean into the Levant during the Bronze Age (Kuhrt 1995; Tubb 1998); the expansion of Greek Phrygian, and Armenian speakers into western Anatolia, and Armenia, respectively, ~1200 B.C. (Redgate 1998); and the importation of European as well as African slaves by the Islamic caliphs of Syria and Iraq during the medieval period (Lewis 1998)."
"Extrapolating from the frequency of these clusters in the Near East has provided us with estimates for back-migration in general. These are strikingly high. We estimate that 10% - 20% of extant Near Eastern lineages have a European ancestry..."
