Haplogroup T-L206 (Y-DNA)

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 two primary branches of T (T-M184), the other subclade being T2 (T-PH110).

Haplogroup T-L206
Possible time of origin26,800 BP [1]
Possible place of originMiddle East [2][3][4]
AncestorT (T-M184)
DescendantsT1a (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 the Middle East 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.[5][6][7]

T-L206's sole primary branch, T1a (M70), is believed to have originated about 15,900 – 23,900 BP,[8] in the Levant. It appears that individuals bearing T-M70 later migrated south to Africa.[9]

T1a (M70)

Initial research on T1a-M70 (previously K2)
M70 is believed to have originated in Asia after the emergence of the K-M9 polymorphism (45–30 ky) (Underhill et al. 2001a). As deduced from the collective data (Underhill et al. 2000; Cruciani et al. 2002; Semino et al. 2002; present study), K2-M70 individuals, at some later point, proceeded south to Africa. While these chromosomes are seen in relatively high frequencies in Egypt, Oman, Tanzania, Ethiopia, they are especially prominent in the Fulbe 18%( [Scozzari et al. 1997, 1999])

J. R. Luis et al. 2004, [10]

Three genetically different populations in the Balearic Islands, Catalonia, Spain
The population of the Pityusic Islands does present a clear genetic divergence in relation to the Mallorcan and Menorcan populations. Neither [does it show] a confluence with the Catalan and Valencian populations ... [T]he data provided by the Pityusic population [compared] with other circumediterranean populations surprises [in] that practically there is no convergence with any of these populations, not even with ... North African populations. The Pityusic case is paradigmatic: ... some markers shows affinities with [Middle Eastern] ... mtDNA variables ... but [the Pityusic population] diverges from these populations when considering other markers. [It] is a separate case, a island, not [just] in the geographical sense but [also a] genetical [island].

Mendez et al. (2011) points to an ancient presence for T1a-M70 in Europe may reflect early exiles between the ancient lands of Israel and Babylon. The subclade probably arrived with the very first farmers.[6] This is supported by the recent findings of Haak et al. who discovered several T1a1-CTS880 members in a 7000 years old settlement in Karsdorf, Germany.[15][16] Autosomal analysis of these skeletal remains show an unusual relationship with modern Southwest Asian populations, reaching close to 10%.

The T1a1 skeletal remains from this settlement were also found to belong to the H mtdna haplogroup, this settlement have the highest frequency of this mtDNA haplogroup 30.4% (7/23) that have been found in any early Neolithic Europe population until now.[15]

T1a1 (L162; xL208)

T1a1 formed 17,400-14,600 BP, is the largest lineage downstream from T1a-M70 and became widespread across Eurasia and Africa before the modern era.

This extremely rare subclade has been found in Ibizan (Eivissan) islanders and Pontic Greeks from Giresun. The first Y-STR haplotype belonging to this lineage appeared in the paper of Tomas et al in 2006 among a sample of Eivissan individuals but is not until August 2009 when the first T1a1-L162(xL208) individual was reported in a 23andMe customer of Pontic Greek background and Metaxopoulos surname, thanks to the public Adriano Squecco's Y-Chromosome Genome Comparison Project.

Pontic Greeks from Giresun descend from Sinope colonists and Sinope was colonised by Ionians from Miletus. Is interesting to note that there exist an Ionian colony known as Pityussa just like the known Greek name for Eivissa Pityuses. In Eivissa, where is found the famous bust of Demeter that have been confused with the punic Tanit for decades, is known the cult to Demeter. The bust belonging to Demeter have been analysed and is found to contains black particles of volcanic sand origin from the Etna, is thought to be made in Sicily with red clays typical of the eastern Trinacria, which was colonized by the Ionians. The Ionians could be arrived to Eivissa c.2700 YBP. This lineage could be an Ionian marker. T1a1 formed 17,400-14,600 BP, is the largest lineage downstream from T1a-M70 and became widespread across Eurasia and Africa before the modern era.

T1a1a (L208)

This lineage, formed 14,200-11,000 BP, is the largest branch downstream T1a1-L162. First discovered and reported in August 2009 in a 23andMe customer of Iberian ancestry that participated in the public Squecco's Y-Chromosome Genome Comparison Project and appearing there as "Avilés" and as "AlpAstur" in 23andMe. Named as "L208" at November 2009.

NotesEvidence of a northerly origin for this population, possibly indicating an influx from the region of northeastern Anatolia.

Haplogroup T is found among the later Middle Pre-Pottery Neolithic B (MPPNB) inhabitants from the 'Ain Ghazal archaeological site (in modern Jordan). It was not found among the early and middle MPPNB populations. It is thought that the Pre-Pottery Neolithic B population is mostly composed of two different populations: members of early Natufian civilisation and a population resulting from immigration from the north, i.e. north-eastern Anatolia. However, Natufians have been found to belong mostly to the E1b1b1b2 lineage – which is found among 60% of the whole PPNB population and 75% of the 'Ain Ghazal population, being present in all three MPPNB stages.

As was previously found in the early Neolithic settlement from Karsdorf (Germany) a subclade of mtDNA R0 was found with Y-DNA T at 'Ain Ghazal.

Later MPPNB populations in the Southern Levant were already witnessing severe changes in climate that would have been exacerbated by large population demands on local resources. Beginning at 8.9 cal ka BP we see a significant decrease in population in highland Jordan, ultimately leading to the complete abandonment of almost all central settlements in this region.[83]

The 9th millennium Pre-Pottery Neolithic B (PPNB) period in the Levant represents a major transformation in prehistoric lifeways from small bands of mobile hunter–gatherers to large settled farming and herding villages in the Mediterranean zone, the process having been initiated some 2–3 millennia earlier.

'Ain Ghazal (" Spring of the Gazelles") is situated in a relatively rich environmental setting immediately adjacent to the Wadi Zarqa, the longest drainage system in highland Jordan. It is located at an elevation of about 720m within the ecotone between the oak-park woodland to the west and the open steppe-desert to the east.

Evidence recovered from the excavations suggests that much of the surrounding countryside was forested and offered the inhabitants a wide variety of economic resources. Arable land is plentiful within the site's immediate environs. These variables are atypical of many major neolithic sites in the Near East, several of which are located in marginal environments. Yet despite its apparent richness, the area of 'Ain Ghazal is climatically and environmentally sensitive because of its proximity throughout the Holocene to the fluctuating steppe-forest border.

The Ain Ghazal settlement first appear in the MPPNB and is split into two MPPNB phases. Phase 1 starts 10300 yBP and ends 9950 yBP, phase 2 ends 9550 yBP.

The estimated population of the MPPNB site from ‘Ain Ghazal is of 259-1,349 individuals with an area of 3.01-4.7 ha. Is argued that at its founding at the commencement of the MPPNB ‘Ain Ghazal was likely 2 ha in size and grew to 5 ha by the end of the MPPNB. At this point in time their estimated population was 600-750 people or 125-150 people per hectare.

Notable members

Elite endurance runners

Possible patterns between Y-chromosome and elite endurance runners were studied in an attempt to find a genetic explanation to the Ethiopian endurance running success. Given the superiority of East African athletes in international distance running over the past four decades, it has been speculated that they are genetically advantaged. Elite marathon runners from Ethiopia were analysed for K*(xP) which according to the previously published Ethiopian studies is attributable to the haplogroup T[84]

According to further studies,[6] T1a1a* (L208) was found to be proportionately more frequent in the elite marathon runners sample than in the control samples than any other haplogroup, therefore this y-chromosome could play a significant role in determining Ethiopian endurance running success. Haplogroup T1a1a* was found in 14% of the elite marathon runners sample of whom 43% of this sample are from Arsi province. In addition, haplogroup T1a1a* was found in only 4% of the Ethiopian control sample and only 1% of the Arsi province control sample. T1a1a* is positively associated with aspects of endurance running, whereas E1b1b1 (old E3b1) is negatively associated.[85]

Thomas Jefferson

Thomas Jefferson
Phylogenetic network analysis of its Y-STR (short tandem repeat) haplotype shows that it is most closely related to an Egyptian K2 [now T/K1a] haplotype, but the presence of scattered and diverse European haplotypes within the network is nonetheless consistent with Jefferson's patrilineage belonging to an ancient and rare indigenous European type. This is supported by the observation that two of 85 unrelated British men sharing the surname Jefferson also share the President's Y-STR haplotype within haplogroup K2.

Turi E. King et al., [86]

A notable member of the T-M184 haplogroup is the third US President, Thomas Jefferson. He reportedly belongs to a subclade of T-M184 which is most commonly found in both the Iberian Peninsula (e.g. Spain) and Egypt. His most distant known ancestor is Samuel Jeffreason  [sic], born 11 October 1607 at Pettistree, Suffolk, England, although there is also a widespread belief that the President had Welsh ancestry. While all subclades of T-M184 are rare in Britain, some British males with the surname Jefferson have also reportedly been found to carry T-M184, reinforcing the idea that Thomas Jefferson's immediate paternal ancestry was British and may originate in Sephardic (Spanish) Jewish populations, who have their ultimate origins in the Middle East.[87]

There was controversy for almost two centuries regarding allegations that Thomas Jefferson had fathered the children of his slave Sally Hemings. An oral tradition in the Hemings family and other historical evidence was countered in the early 19th century by some Jefferson's grandchildren, who asserted that a son of Thomas Jefferson's sister, by the name of Carr, had been the father of Hemings' children. However, a 1998 study of Jefferson male-line DNA found that it matched that of a descendant of Sally Hemings' youngest son, Eston Hemings. Most historians now believe that Jefferson had a relationship with Hemings for 38 years, and probably fathered her six known children, four of whom lived to adulthood. In addition, the testing conclusively disproved any connection between the Hemings descendant and the Carr male line.

Phylogenetic history

Prior to 2002, there were in academic literature at least seven naming systems for the Y-Chromosome Phylogenetic tree. This led to considerable confusion. In 2002, the major research groups came together and formed the Y-Chromosome Consortium (YCC). They published a joint paper that created a single new tree that all agreed to use. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. The table below brings together all of these works at the point of the landmark 2002 YCC Tree. This allows a researcher reviewing older published literature to quickly move between nomenclatures.

PMID 21453003. S2CID 207611348. Estimates of the timing of the branching events within haplogroup T, along with a comprehensive geographic survey of the major T subclades, suggest that this haplogroup began to diversify in the Near East ~25 kya. Our survey also points to a complex history of dispersal of this rare and informative haplogroup within the Near East and from the Near East to Europe and sub-Saharan Africa.
