North Africans are not one people who arrived once. They are layers: deep local roots, joined again and again by farmers, traders and travellers, and sending people out across the sea in turn. One family from the Souss valley shows how those layers meet in a single household.

The numbers that matter
Every figure is an estimate with a published range. The ranges are in the timeline below, each linked to its paper.
The layers, in order
Each step comes from a peer-reviewed study summarised on this site, with its published date range. The link takes you to the summary and, from there, to the paper.
-
More than 20,000 years ago
Roots that go deep
The ancestry of today's Amazigh (Berber) people goes back more than 20,000 years in North Africa, to a movement back into Africa from Eurasia. Genome modelling puts the first separation between the region's Amazigh and Arab populations that far back: a slow drift apart, not a clean break (Serradell et al. 2024).
-
15,100–13,900 years ago
The Taforalt foragers
The deepest layer that can be measured in Amazigh genomes today links to the Iberomaurusian foragers of Taforalt, in Morocco (Vilà-Valls et al. 2024).
-
About 15,000–7,600 years ago
One local ancestry, west to east
The same Maghrebi forager profile ran from Morocco to Algeria and Tunisia for thousands of years. Around 8,000 years ago, one person in Tunisia already carried ancestry related to European hunter-gatherers (Lipson et al. 2025).
-
About 7,500–5,000 years ago
Farming arrives with people
Early farmers in Morocco carried two incoming ancestries, from Iberian farmers who crossed the Strait of Gibraltar and from Levantine farmers, mixed with local foragers rather than replacing them (Villalba-Mouco et al. 2023). Further east, local ancestry held on, with smaller farmer contributions by about 7,000–6,800 years ago (Lipson et al. 2025).
-
About 7,000 years ago
A green Sahara
Genomes from Takarkori, in Libya, date to a time when the Sahara was grassland. They carry a previously unknown, deeply divergent lineage from a population that was largely isolated from its neighbours (Salem et al. 2025).
-
Late Pleistocene to recent times
Women's lines, in waves
Complete mitochondrial genomes show several waves of female-mediated movement shaping the region (Colombo et al. 2025), on top of a maternal core so shared that populations across the Maghreb differ only slightly from one another (Boumajdi et al. 2026).
-
About 2,000–3,000 years ago
One father's line spreads fast
E-M81, the most common Y-chromosome among Amazigh men, traces back to a small founding group that expanded quickly (Solé-Morata et al. 2017).
-
1st millennium BCE
Out into the Atlantic
Amazigh settlers reached the Canary Islands. Their descendants stayed genetically close to mainland North Africans until the European conquest of the 15th century (Santana et al. 2025).
-
The Punic period
Culture travels further than people
Punic settlements across the Mediterranean carried little Levantine ancestry, despite their Phoenician culture. Most was related to groups from Sicily and the Aegean, with a recurring North African share linked to Carthage (Reich et al. 2025).
-
The Middle Ages
North Africa moves north
North African ancestry reached Sicily before the Islamic conquest (Monnereau et al. 2026), and Ibiza in two pulses, in the 10th and 12th centuries CE (Rodríguez-Varela et al. 2026).
-
The last 1,400 years
Arabization, and two Saharan waves
Arab genetic input into North Africa is recent, mostly within the last 1,400 years (Serradell et al. 2024). Sub-Saharan ancestry reached Amazigh groups in at least two waves, around the 12th and 19th centuries CE, strongest near the caravan routes (Vilà-Valls et al. 2024).
Where one family fits
Every North African carries these layers in a different mix. Here is one real sample: an Amazigh (Berber) family from Souss-Massa, Morocco, read through the two DNA lines that pass down almost unchanged, father to son and mother to child.
The father's line: E-PF2546
A branch of E-M81, still the most common Y-chromosome in Morocco, Algeria and Tunisia (Boumajdi et al. 2026). E-M81 grew from a small founding group that spread fast about 2,000–3,000 years ago (Solé-Morata et al. 2017).
In the timeline: One father's line spreads fast
The mother's line: H1-T16189C!
Haplogroup H is one of the three main maternal groups in North Africa today (Boumajdi et al. 2026). Its H1 branch came from Europe. When is debated: mitochondrial dating points to the early Holocene (Colombo et al. 2025), and the best-supported route is with the farmers who crossed from Iberia (Villalba-Mouco et al. 2023).
In the timeline: Farming arrives with people and Women's lines, in waves
An African father's line beside a mother's line from Europe is not a contradiction. It is the regional pattern these studies describe: a local father-line that is still the most common, and women's lines arriving in waves. It is still only a sample: two ancestors out of more than a thousand, and a haplogroup is not an ethnicity. What this sample cannot show.
What these papers do not cover yet
The studies summarised here say little about North Africa in the Roman, Vandal and Byzantine centuries. None has ancient DNA from the 7th-century Arab conquest itself: the dating of Arab ancestry above comes from the genomes of people alive today. And none covers ancient Egypt or the Nile valley.
Until a study does, this page says nothing about them. What this evidence cannot show sets out the other limits.
