The Kabyles and the Myth of Nordic Origins

Browse social media long enough and you will inevitably encounter it: a photograph of a Kabyle child with blue or green eyes, captioned as proof of Celtic, Vandal, Roman, or "proto-European" descent. These posts accumulate thousands of shares within Amazigh communities and beyond. The idea is seductive, even romantic, but it is genetically incorrect.

This is not to say that light eyes among Kabyles are a myth. They are entirely real, and they have a rigorous genetic explanation. The problem is that this explanation has nothing to do with Vandals, Celts, or some hypothetical "Nordic race" sheltering in the mountains of Kabylia. It runs through something far older and far more interesting: the Neolithic farmers who shaped the entire Mediterranean world more than 7,000 years ago.

Who Are the Kabyles? An Amazigh People of Kabylia

The Kabyles are an Amazigh (Berber) people living primarily in Greater Kabylia and Lesser Kabylia, in northeastern Algeria, a mountainous region stretching from the Mediterranean coast to the foothills of the Atlas. They speak Taqbaylit (Kabyle), a Berber language of the Afro-Asiatic family, and constitute one of the best-documented Amazigh populations genetically in Algeria.

The term "Amazigh" (plural: Imazighen) is the historical self-designation of the people commonly called "Berbers", the latter being a loanword from the Latin barbarus, used by Romans to refer to non-Romanised populations. The Imazighen are the descendants of the indigenous inhabitants of North Africa since at least the Epipalaeolithic, that is, since approximately 15,000 to 13,000 BCE, as confirmed by the remains recovered at Taforalt in Morocco.^{[1, 3]}

A Genetic History in Four Acts

To understand Kabyle genetics, we must go back well before the Romans, well before the Phoenicians, and well before the first cities. Four major migratory waves shaped the genomes of North African populations:^{[2, 4]}

G25 Modelling: What Do the Coordinates Show?

The Standard G25 Calculator (by Davidski, available on ExploreYourDNA) models Berber populations with an excellent fit. Here are the results for the three main Algerian Amazigh populations:

Fig. 1, G25 modelling of the Kabyle population (Algerian*Berber*Kabyle). Nearly all so-called "European" ancestry is in fact Anatolian Neolithic. WHG (Western Hunter-Gatherers, the actual pre-Neolithic Europeans) represents only 1.6%.

Fig. 2, The Mozabites, an Ibadi-isolated Algerian Saharan population, show a richer Taforalt signal (33.4%) and less Steppe ancestry than the Kabyles, reflecting greater long-term isolation.

Fig. 3, The Timimoun, located at the Saharan fringe, show a markedly higher sub-Saharan component (15% Yoruba) attributable to trans-Saharan trade routes, and substantially less coastal Anatolian Neolithic ancestry.

Light Eyes: A Neolithic Story, Not a Celtic One

Let us address the core of the myth directly. Why do some Kabyles have blue or green eyes? The answer lies primarily in two genes: HERC2 and OCA2, located on chromosome 15. A specific substitution in HERC2 (rs12913832) reduces OCA2 expression, lowering melanin production in the iris and resulting in lighter eye colour.

What is crucial, and consistently ignored in popular discussions, is that these variants do not belong exclusively to Northern European populations. They were already present in Anatolian Neolithic farming populations and their descendants throughout the Mediterranean, including the farmers who colonised North Africa from around 7,500 BCE onward.

In concrete terms, the Kabyles show 53.2% Anatolian Neolithic ancestry (Barcin + Tepecik), versus only 1.6% WHG (Western Hunter-Gatherers, the actual pre-Neolithic inhabitants of Western Europe). If Kabyle light eyes derived from "Nordic" or Western European populations, we would expect substantially higher WHG or Yamnaya ancestry. The data show nothing of the sort.

WHG: Hunter-Gatherer, Not "Nordic"

It is tempting to conflate WHG (Western Hunter-Gatherers) with Celts or Nordic peoples. This is a framing error. WHG designates Mesolithic populations who inhabited Europe before the arrival of Neolithic farmers, groups such as the individuals from La Braña (Spain, ~7,000 BCE) or Loschbour (Luxembourg). They have no relationship whatsoever to the Gauls, the Vandals, or any historical culture.

Moreover, WHG individuals themselves had variable pigmentation: light eyes were common, but some, such as La Braña 1, combined blue eyes with very dark skin. Light eye colour therefore has multiple ancestral sources, and its presence among Berbers does not point toward any particular historical European group.^[2]

Taforalt: The True Autochthonous Substrate

The most "autochthonous" component in Kabyle ancestry is not European, it is the Taforalt / Iberomaurusian signal, representing 29.6% of their genome in our model. These individuals, whose DNA was recovered from the Taforalt cave in Morocco and dated to 15,000, 13,900 BCE, represent the earliest genetically documented inhabitants of North Africa.^{[3, 6]}

Their primary ancestry is close to Natufians of the Near East, suggesting a "back-to-Africa" movement from western Asia, long before the Neolithic. These individuals already carried mitochondrial haplogroups U6 and M1, which remain characteristic of North Africa to this day.

According to Serradell et al. (2024), the Imazighen show genetic continuity traceable back to this Epipalaeolithic period, with an origin distinct from North African Arab populations whose divergence from the Middle East is more recent.^[2] The best-supported demographic model (D4, using ABC Deep Learning) places the divergence of the Imazighen from other Eurasian populations at a point predating even the European / Middle Eastern split.

Geographical Heterogeneity Among the Imazighen

An important and frequently overlooked point: the Imazighen do not form a homogeneous genetic bloc. Vilà-Valls et al. (2024) studied three Chaouïa populations from the Aurès mountains (Batna, Khenchela, Oum El Bouaghi) and demonstrated significant microgeographical heterogeneity within an area of only ~2,500 km². The Khenchela population shows notably higher inbreeding levels, visible in their ROH (runs of homozygosity) profiles.^[3]

This internal heterogeneity explains why phenotypic traits, including light eye pigmentation, can vary considerably from one village to the next, one valley to the next, without reflecting any distinct historical migration event. Geographic isolation in mountain environments amplifies genetic drift, allowing certain variants (such as those associated with light eyes) to reach higher frequencies in isolated local populations purely by chance.

The Sub-Saharan Component: The Trans-Saharan Slave Trade

Our models show approximately 5% sub-Saharan ancestry in the Kabyles (Yoruba + Dinka + Gambian). This component is well-documented in the scientific literature: it is the result of the trans-Saharan slave trade, which brought populations from sub-Saharan Africa northward from Roman times through the 19th century.^[4]

Lucas-Sánchez et al. (2023) dated two main admixture events in North African populations: a first peak around the 13th, 14th centuries CE, involving West African populations similar to present-day Senegambians, and a second around the 17th century CE involving East African populations. The Kabyles, situated in the far north and relatively distant from the main Saharan routes, show among the lowest sub-Saharan components of any Algerian Amazigh group. The Timimoun, in the Saharan zone, show ~17% sub-Saharan signal by contrast.^[4]

G25 Coordinates: Model It Yourself

Here are ready-to-use G25 coordinates for Vahaduo. The Algerian*Berber*(Kabyle) averaged population is the most representative reference target for Kabyle modelling. Individual Berber_Algeria samples are also provided for those wishing to explore internal variation.

Individual Berber_Algeria Samples (for Internal Variation)

These 7 individuals are the most representative of a coastal/northern Kabyle-type profile (high North African component, low sub-Saharan). BerZN103, BerZN113, and BerZN131, strongly displaced on PC1, represent deeply isolated deep-Atlas Berbers and are less representative of Kabyle populations.

Summary: What DNA Actually Tells Us About the Kabyles

Kabyle genetics tells a far richer story than any myth about "Celtic or Vandal descendants". Here is what the numbers show:

The Kabyles are an Amazigh people with a deep and layered genetic history, whose distinctiveness derives precisely from the superimposition of these four strata, the Iberomaurusian, the Mediterranean Neolithic, a trace of the Steppe, and the Sahara, and not from any hypothetical European "purity" preserved in the mountains.
