Haplogroup T1 Distribution

Return to mtDNA Test Results Summary Page

The mitochondrial Haplogroup T is best characterized as a European lineage. With an origin in the Near East greater than 45,000 years ago, the major sub-lineages of Haplogroup T entered Europe around the time of the Neolithic 10,000 years ago. Once in Europe, these sub-lineages underwent a dramatic expansion associated with the arrival of agriculture in Europe. It is presently found throughout Western Eurasia, including North Africa, the Arabian Peninsula, and occasionally in the Near East. About 10% of Europeans carry haplogroup T. Carriers of this line are most abundant in southern and western Europe. They are next most abundant in Ireland and western Britian.This haplogroup is a sister to haplogroup J as both carry a similar variation pattern and originated about 30,000 years ago probably in the Near East. Haplogroup T itself probably ofiginated in present-day northwestern Italy about 17,000 years ago.

The origin of Haplogroup T1 dates to at least 6,000 years ago, and today, we find Haplogroup T1 distributed in populations living in southeast, central, and northwestern Europe.
