The Moroccan
Genome
300,000 years of migration written in nucleotides. What DNA and identity say about who Moroccans are.
Morocco sits at the crossroads of three continents. The Sahara to the south, the Mediterranean to the north, the Atlantic to the west, and a land bridge to the Middle East through Sinai. Every empire that crossed this intersection left its DNA. In 2025, the Moroccan Genome Project sequenced 109 whole genomes and found the answer: the average Moroccan is 51% autochthonous North African — an ancestry found nowhere else on Earth at high frequency — plus 11% European, 11% Middle Eastern, and 7% West African. The most common paternal lineage, E-M81, is only 2,000–3,000 years old — one of the most rapid genetic expansions ever documented. And the single most important finding: there is almost no genetic difference between Berber-speaking and Arab-speaking Moroccans. Arabisation was a language shift, not a population replacement.
51.2%
North African ancestry
The majority component. Autochthonous. Not found at high frequency anywhere else on Earth.
E-M81
Dominant paternal lineage
79–98% in Amazigh men. Only 2,000–3,000 years old. One of the most rapid Y-chromosome expansions ever documented.
~0
Genetic difference between Arab and Berber Moroccans
Studies consistently show no strong genetic differentiation. Arabisation was primarily cultural. Berber and Arab Moroccans cluster together genetically.

Years of the oldest Moroccan ancient DNA
Taforalt cave. Already showed mixed Eurasian and African ancestry. Back-to-Africa migration pre-dates all known civilisations.
Section I
The Admixture
Autosomal DNA — the full genome, inherited from both parents — reveals four major ancestry components in the average Moroccan. Based on 109 whole genomes at K=19 resolution. Hover each segment for detail.

Section II
The Father Line
Y-chromosome haplogroups trace the paternal lineage — father to son, unchanged, for thousands of generations. E-M81 is the autochthonous North African marker. J1 arrived with the Arab conquests. R1b crossed from Europe. Hover any bar for the story.

Section III
The Berber Marker
E-M81 (E-M183) is the most common paternal lineage in North Africa. It reaches near-fixation in southern Amazigh communities (98.5%) and declines as you move north, east, and across the Mediterranean. Its TMRCA of just 2,000–3,000 years makes it one of the youngest widespread Y-chromosome lineages ever studied — evidence of an extraordinary recent demographic expansion.

Section IV
The Mother Line
Mitochondrial DNA traces the maternal lineage — mother to child, for hundreds of thousands of years. The Moroccan maternal pool tells a different story than the paternal: more Eurasian, with the North African–specific U6 lineage as the indigenous signature.

Section V
300,000 Years
From the oldest Homo sapiens fossils on Earth to the first national genome reference. Every migration left its mark in the nucleotides.
Homo sapiens remains at Jebel Irhoud, Morocco. Oldest known anatomically modern human fossils.
Taforalt cave (Iberomaurusian). Ancient DNA shows: haplogroup E-M78*, U6, M1 mtDNA. High affinity with Near Eastern Natufians. Evidence of a "back-to-Africa" migration from Western Eurasia.
Ifri N'Ammar (Cardial Neolithic). New arrivals carry Levantine marker E-L19. Break in genetic continuity with Iberomaurusians — Neolithic farmers partially replace earlier populations.
Neolithic demic diffusion from Middle East. Pastoralists introduce J1, G2 haplogroups and Middle Eastern ancestry. Agriculture spreads with genes.
Phoenician colonisation. Carthage founded (814 BCE). Levantine and Mediterranean gene flow into coastal Morocco.
E-M183/M81 undergoes rapid expansion across North Africa. Extremely recent TMRCA. Becomes the dominant paternal lineage in Amazigh populations.
7th–8th century Arab conquest. J1-P58 haplogroup introduced. Arabisation is both cultural AND demographic — recent studies confirm significant gene flow, not just language shift.
Trans-Saharan trade and slave trade introduce West African (L2a, L3b mtDNA) and Sub-Saharan Y lineages (E-V38). Higher frequencies in southern Morocco and urban centres.
Al-Andalus period. Berber and Arab soldiers cross to Iberia. E-M81 found at 5–11% in Spain today. Genetic evidence of Moroccan ancestry in Iberian peninsula.
Moroccan Genome Project Phase 1: 109 whole genomes sequenced. 27 million variants identified, 1.4 million novel. First Moroccan Major Allele Reference Genome (MMARG) proposed.
Section VI
The Identity Question
DNA says most Moroccans are genetically indistinguishable regardless of whether they speak Arabic or Berber. But identity is not DNA. Ask a Moroccan "what are you?" and the answer depends on who is asking, which categories are offered, and what is politically at stake. Every number below is contested.
SELF-IDENTIFICATION (2021 SURVEY, n=1,200)
ENCYCLOPÆDIA BRITANNICA CLASSIFICATION
Note the gap: when Moroccans self-identify, 68% say "Arab." But Britannica classifies only 44% as Arab and adds a category — "Arabized Berber" (24%) — for people who are genetically and historically Amazigh but culturally and linguistically Arab. The Amazigh movement contests all of these numbers, arguing that 40–85% of Moroccans are of Amazigh origin, and that centuries of Arabisation policy have suppressed indigenous identity.
MOTHER TONGUE — 2024 CENSUS
Amazigh speakers total 24.8% (percentages overlap due to bilingualism). Amazigh activists claim methodology undercounts, estimating 40%+.
BERBER-SPEAKING POPULATION (% BY CENSUS)
Berber-speaking Moroccans have declined from 32% at independence (1960) to 24.8% in the 2024 census. Amazigh organisations call this "linguistic genocide" — the result of decades of Arabisation in education, media, and administration. The 2011 constitution made Tamazight an official language, but literacy in Berber remains at just 1.5%.
THE THREE AMAZIGH LANGUAGE ZONES + HASSANIYA
Tashelhit (Shilha)
14.2%Souss Valley, High Atlas, Anti-Atlas · ~5.2 million
Largest Amazigh group in Morocco. ~8 million including diaspora. Rich oral poetry tradition (amarg). Historically important commercial class.
Central Atlas Tamazight
7.4%Middle Atlas, eastern High Atlas, Taza to Tafilalt · ~2.7 million
Foundation for Standard Moroccan Amazigh. 40–45% of speakers monolingual. Extends from forested mountains to Saharan oases.
Tarifit
3.2%Rif Mountains, northern Morocco · ~1.2 million
Historically most isolated. Strong diaspora in Belgium, Netherlands. Low mutual intelligibility with Tashelhit. Centre of 1958–59 Rif rebellion and 2016–17 Hirak protests.
Hassaniya Arabic
0.8%Southern provinces, Western Sahara · ~300,000
Arabic dialect of Sahrawi population. Mix of Arab-Amazigh tribal heritage. Traditionally nomadic Bedouin. Centre of Western Sahara sovereignty dispute.
Section VII
The Invisible Groups
The Arab-Berber binary leaves out the Moroccans who fit neither category. These communities are rarely counted in censuses or surveys, but they are woven into the country's fabric.
Haratin
Dark-skinned agriculturalists of the southern oases (Drâa-Tafilalet). Not necessarily of slave origin — historian Chouki El Hamel argues many descend from native Black populations predating the Arab conquest. Concentrated in Zagora, Ouarzazate, Tinghir. Formerly the majority in parts of southern Morocco. The term itself is considered pejorative; many prefer "Drawi" or "Sahrawi."
Gnawa
Descendants of West African enslaved peoples (Soninke, Bambara, Fulani, Hausa) brought via trans-Saharan trade from 10th–19th centuries. Concentrated in Marrakech and Essaouira. Created a unique Sufi-African spiritual music tradition now recognised by UNESCO (2019). The name likely derives from Berber "agnaw" (Black person).
Moriscos
Descendants of Muslim refugees expelled from Spain after the Reconquista (15th–17th centuries). Settled primarily in Rabat (Salé), Fez, Tetouan, Chefchaouen. Brought Andalusian architecture, music (malhun, andalusi), cuisine, and craft traditions that remain central to Moroccan urban culture.
Jewish Moroccans
Present since at least the destruction of the First Temple (586 BCE). Peaked at 250,000 in 1948. Now ~2,500 in Morocco (largest Jewish community in the Arab world). Most emigrated to Israel, France, Canada after 1948. Morocco maintains Jewish heritage sites and the only Jewish museum in the Arab world (Casablanca).
Sub-Saharan migrants
Growing community since 2000s. Morocco regularised ~50,000 irregular migrants in 2014 and 2017. Primarily from Senegal, Guinea, Côte d'Ivoire, Mali, DR Congo. Some in transit to Europe; increasingly settling permanently. Complex relationship with existing Black Moroccan communities.
Reading Notes
Arab ≠ Arabian
The biggest surprise in Moroccan genetics: Berber-speaking and Arab-speaking Moroccans are genetically nearly indistinguishable. In PCA plots, both groups cluster together. Earlier studies suggested Arabisation was purely cultural — a language shift without population replacement. More recent work (2017, 2024) shows it was both: real gene flow occurred, but the indigenous Berber substrate remained dominant. Being "Arab" in Morocco is primarily a linguistic identity, not a distinct genetic ancestry.
The Counting Problem
Morocco has never conducted an ethnic census. All numbers are estimates or language proxies. A 2021 survey says 68% Arab; Britannica says 44%. The gap is the "Arabized Berber" — people genetically Amazigh who speak Arabic and identify as Arab. The 2024 census found 24.8% speak Berber, but Amazigh groups say the real figure is 40–85%, arguing the methodology undercounts. The 2011 constitution acknowledged the problem by defining Morocco's identity as "Arab-Islamic, Amazigh, and Saharan-Hassani." Even the state admits it is all three.
"I Am from Here"
In 2020, Black Moroccan artist M'Barek Bouhchichi said: "Any Black person in Morocco is told they came from sub-Saharan Africa. And this is where they are wrong. I am from here." Historian Chouki El Hamel argues the Haratin are not descendants of slaves but native Black populations who inhabited southern Morocco before the Arab conquest. The assumption that darker skin equals foreign origin is both genetically and historically unfounded — yet it persists, structuring social hierarchies in the south. Out of 515 members of parliament, only 7 are Black.
The Back-to-Africa Migration
Taforalt cave in eastern Morocco (15,000 ya) contained the oldest DNA in North Africa — and it showed high affinity with Near Eastern Natufian populations. This means the indigenous "North African" ancestry itself came from Eurasia, in a back-migration predating the Holocene. The U6 and M1 mitochondrial lineages are the molecular evidence. North Africa was populated from both directions: out of Africa, and then back into it.
The 2,000-Year-Old Marker
E-M81 is found at 80–98% in Amazigh men across Morocco, Algeria, Tunisia, and Libya. Yet its most recent common ancestor lived only 2,000–3,000 years ago. This is extraordinarily young for a lineage at such high frequency. It implies a massive, rapid demographic expansion — possibly linked to the development of oasis agriculture, Berber confederations, or trans-Saharan trade networks that gave certain lineages an outsized reproductive advantage.
The Sahrawi Question
Sahrawis — Hassaniya-speaking tribes of mixed Arab-Amazigh descent — represent roughly 3.6% of Morocco's population. They are genetically similar to southern Moroccans and Mauritanians, with E-M81 at ~76% in Sahrawi men. The Western Sahara sovereignty dispute makes their demographic counting politically charged: Morocco claims the territory; the Polisario Front seeks independence. An estimated 90,000–190,000 Sahrawis live in the disputed territory, with ~165,000 in refugee camps in Algeria.
