15% vs 8%: Galicians Have Twice the North African DNA of Andalusians, According to Recent Genetic Data
This question sounds like a tavern provocation, but it has a historical and scientific foundation worth examining without filters. An analysis of genetic studies published in specialized forums indicates that the Iberian Northwest — Galicia and Portugal — concentrates the highest percentages of North African ancestry in the entire Iberian Peninsula, clearly surpassing Andalusia. If confirmed, these figures would turn the mental map of “the further south, the more Moorish” upside down.
According to the data, Galicia has 15% North African component, Portugal 18% (plus 4% Sub-Saharan), Extremadura 11% (plus 3% Sub-Saharan), while Andalusia stands at 8% and Valencia at 5%. The explanation lies not in the Muslim invasion of 711, but in Romanization. The mines of the Northwest attracted North African workers and soldiers during the 1st to 5th centuries AD, as demonstrated by the Miroico (up to 40% North African DNA) and Conimbriga (17%) sites.
The Celtic Myth vs. Genetic Evidence
The Galician self-image as a “Celtic people” clashes with these numbers. For decades, the identity discourse has emphasized ties with Ireland and Scotland, based on music, the bagpipe, and certain place names. However, autosomal DNA analysis places Galicia and Portugal as the regions with the greatest North African influence in Europe, far above areas that were under Sarracinic rule for longer.
The paradox is explained by a double process: first, the Roman colony brought Berber labor for gold mining (Las Médulas, Northwest operations); second, during the Reconquista, Moriscos and Berbers who collaborated with the Christian kingdoms were deliberately displaced westward — away from the Mediterranean coast, vulnerable to new invasions — settling in Galicia and western Castile. A settlement pattern that, according to some historians, explains the east-west gradient, not north-south.
The Defense of the Celtist Narrative
Against this current, some argue that genetic evidence is inconclusive. It is argued that the “North African component” may actually be early Neolithic heritage or from Caucasus populations (Zagrosian), and that the cited percentages come from studies with small samples or questionable methodologies. Furthermore, phenotype — physical appearance — does not necessarily correspond to genotype: in Lugo and La Coruña there are as many blond blue-eyed people as in Northern Europe.
Another recurring point is that North African DNA is also highly present in Portugal and Extremadura, indicating that the determining factor is not the “Moor” in the strict sense, but the population flows of late antiquity. The Celtist thesis, although weakened, still has defenders who appeal to material culture (castros, toponymy) and historical tradition.
With this data on the table, the discussion transcends mere regional confrontation. It reveals how identity narratives can construct a reality that genetics refutes, and how history — with its poorly documented population movements — continues to surprise us. The reader who wishes to delve deeper will find in the complete analyses a breakdown of the genetic studies and Roman settlement maps.
