Haplogroup T-L206
Haplogroup T-L206, also known as haplogroup T1, is a human Y-chromosome DNA haplogroup. The SNP that defines the T1 clade is L206. The haplogroup is one of two primary branches of T (T-M184), the other subclade being T2 (T-PH110).
| Haplogroup T-L206 | |
|---|---|
| Possible time of origin | 26,800 BP |
| Possible place of origin | Western Asia |
| Ancestor | T (T-M184) |
| Descendants | T1a (T-M70) |
T1 is the most common descendant of the T-M184 haplogroup, being the lineage of more than 95% of all T-M184 members in Africa and Eurasia (as well as countries to which those populations have migrated in the modern era, in the Americas and Australasia). T1 lineages are now found at high frequencies among northern Somali clans. It is hypothesized that T1* (if not some of its subclades) originated in Western Asia, and spread into Europe and North Africa with the Pre-Pottery Neolithic B culture (PPNB).
The basal clade T1* is rare, but has been found in at least three males from widely separated regions: a Berber from Tunisia, a Syrian, and a Macedonian.
T-L206's sole primary branch, T1a (M70), is believed to have originated about 15,900 – 23,900 BP, in the Levant. It appears that a number of individuals bearing T-M70 later migrated south to Africa.
