mtDNA U6 in North Africa: A 35,000-Year-Old Migration from Europe with Aurignacian Tools
North Africa’s earliest European maternal lineage, mtDNA haplogroup U6, arrived c.~35,000 years ago (kya)—a direct migration of modern humans from Europe into the continent.
Origin and Timing
- U6 originated in Europe ~43–35 kya.
- Direct evidence: Basal U6* in a 35,000-year-old Homo sapiens from Peștera Muierii, Romania.
- Migration to North Africa: ~35 kya.
- Local expansion: U6a diversified in the Maghreb by ~26 kya, tied to Iberomaurusian hunter-gatherers.
Accompanying Technology: Aurignacian-Style Tools
The same migrants introduced Upper Paleolithic bladelet technology—the Aurignacian toolkit of Europe—but without art.
No cave art, figurines, or flutes—only functional tools and shell ornaments.
- U6 = genetic proof of European migration.
- Aurignacian-style tools = archaeological proof of the same movement.
- No art – focus on utility.
This European pulse left U6 as a lasting maternal marker in modern Berbers and Canary Islanders.

Calendar Math — Exact Match
- Anno Mundi (AM) 1 = 5509 BCE (Byzantine Creation Era)
- + 25,772 years into the past = 5509 + 25,772 = 31,281 BCE → ~31.3 kya (thousand years ago)
This is not coincidence — it lands squarely in the Upper Paleolithic, during the Last Glacial Maximum (LGM) and the Aurignacian expansion.
2. Genetic & Cultural Wave at ~31–35 kya
- U6 migration from Europe | ~35 kya | Romania → North Africa
- Aurignacian tools enter North Africa | ~35–31 kya | Dabban (Libya), Proto-Iberomaurusian (Morocco)
- Peștera Muierii woman (U6 carrier) | 35 kya | Romania
03. The “Hera” Connection — Taurus 8th Age (~32–30 kya)
- “Hieroglyphs” → HERA → 8th Age of Taurus (~31.2–29 kya)
- Anno Mundi 1 (AM )+ 25,772 = 31,281 BCE falls in the 8th Age of Taurus.
mtDNA U6 evolved and diversified extensively in North Africa after its ~35 kya arrival from Europe, providing strong evidence of its European origin (basal U6* in 35 kya Romanian aDNA) followed by separate, regional evolution over the past ~35,000 years. This is based on complete mtDNA sequencing of 230+ U6 genomes and 761 partial sequences, analyzed via Bayesian coalescent methods and phylogenetic trees.
Implication: U6's high diversity in North Africa (vs. Europe) proves post-arrival evolution, with expansions reflecting local adaptations (e.g., to post-LGM warming). This isolates it as a European migrant lineage that became distinctly African.
Evolution and Diversification in North Africa
After arrival, U6 evolved separately over ~35 kya, developing distinct subclades (e.g., U6a via mutations 7805 & 14179) that dominate modern Berber populations (~28% frequency). This diversification—absent in Europe—signals a moderate population expansion during the Late Pleistocene (~26–15 kya), reflecting climatic recovery and local adaptations.
Sub-Saharan admixture remained minimal (~4%) until the Holocene, proving U6's enduring European root with independent African trajectory.
Minimal sub-Saharan African (SSA) ancestry in ancient Egyptian mummies from the New Kingdom to Roman Period (up to ~400 CE, or ~2425 years ago), with a detectable increase in SSA admixture occurring after ~400 CE—i.e., starting ~2300–2000 years ago.
The 2017 Schuenemann study is the foundational work, using high-throughput sequencing on Abusir el-Meleq mummies. It directly contrasts ancient (~low SSA) vs. modern (~high SSA) genomes, with the shift post-dating 400 CE.
The bulk of modern Sub-Saharan African (SSA) ancestry in North Africa arrived in the past ~2,000 years, and the trans-Saharan slave trade is the primary driver.
Key idea -- Schuenemann, 2017: “The increase in Sub-Saharan African ancestry occurred after the Roman Period.” → Post-400 CE = <2,000 years ago.
80–90% of current SSA ancestry in North Africa arrived in the past 2,000 years. Primary cause: The trans-Saharan slave trade (650–1900 CE).
Not ancient migrations. Not natural gene flow. Not predynastic.
It’s a medieval demographic pulse — visible in DNA, history, and archaeology.
