Paternal Haplogroup Origins R-M343Your maternal lineage may be linked to the nomadic Tuareg of the Sahara
Though haplogroup H1 rarely reaches high frequencies beyond western Europe, over 60% of eastern Tuareg in Libya belong to haplogroup H1. The Tuareg call themselves the Imazghan, meaning “free people.” They are an isolated, semi-nomadic people who inhabit the West-Central Sahara and are known today for a distinctive dark blue turban worn by the men, and for their long history as gatekeepers of the desert.How did women carrying H1 make it all the way from western Europe to this isolated community? They likely migrated from Spain across the Strait of Gibraltar into Morocco after the Last Ice Age, where they were assimilated into the Berbers of the Mediterranean coast. Then, about 5,000 years ago, the Sahara shifted from a period of relative habitable conditions to its dramatically arid desert environment. This shift may have caused migrations throughout the Sahara, prompting the ancient Tuaregs to meet and mingle with the Berbers, bringing H1 lineages into their population.
