# 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).
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.

## Subclade distribution
### T1* (T-L206*)

This lineage could have arrived in the Levant through the PPNB expansion from northeastern Anatolia.

| Macedonians | Macedonian (Balto-Slavic) | Macedonia | 1/201 | 0.5% | Orthodox Christians of Macedonian ethnicity |

### T1a (M70)

   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])
   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].

### 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. It is interesting to note that there existed an Ionian colony known as Pityussa, just like the known Greek name for Eivissa Pityuses. In Eivissa, archaeological findings include the famous bust of Demeter which has been confused with the Punic goddess Tanit for decades. The bust belonging to Demeter has been analysed and was found to contain black particles of volcanic sand, originating from Mount Etna. It is thought that the bust was 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.

### T1a1a1a1b1a1a (Y3836)

This lineage is mostly found among individuals from the Iberian Peninsula, where is found their highest diversity. The first Y-STR haplotype of this lineage, characterized by DYS437=13, was found in the public FTDNA Y-DNA Haplogroup T project, appearing there at April 2009 as kit E8011. However, is not until June 2014 when the Y-SNP Y3836 was discovered in the public YFULL project among two of their participants of Iberian ancestry, appearing there as YF01637 and YF01665.

## Ancient DNA
### Peki'in Cave Israel

During the Chalcolithic Period (the “Copper Age,”) In the Northern Galilee town of Peki'in here's a burial cave that dates to over 6,500 years ago. The cave is the largest one known in Israel and contains a wealth of ancient artifacts: decorated ossuaries which some claim is the proto Israelite Burial, burial offerings, jars, stone tools. We find that the individuals buried in Peqi’in Cave represent a relatively genetically homogeneous population. This homogeneity is evident not only in the genome-wide analyses but also in the fact that most of the male individuals (nine out of ten) belong to the Y-DNA Haplogroup T a lineage thought to have diversified in the Near East. 2x T-L208 Peqi'in 1155,1160, 1x T-FT13419 Peqi'in 1165, 4x T-Y4119 Peqi'in ,1166,1170,1172,1178, 2x T-L454 Peqi'in 1180,1187 expressing the upstream and downstream diversity of Haplogroup T-M184 in West Asia its most likely point of divergence.

They were associated with the Kulubnarti Nubians cultural group the Y-DNA was T-Y31479 and T-FT338883 they along with a Haplogroup LT were the three outliers amongst the Nubian elite R cemetery.

## 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
According to further studies, 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.

### Royal House of Khalifa

The House of Khalifa (Arabic: آل خليفة, romanized: Āl Khalīfah) is the ruling family of the Kingdom of Bahrain. The Al Khalifas profess Sunni Islam and belong to the Anizah tribe, some members of this tribe joined the Utub alliance which migrated from Central Arabia to Kuwait, then ruled all of Qatar, more specifically Al Zubarah, which they built and ruled over before settling in Bahrain in the early 17th century. The current head of the family is Hamad bin Isa Al Khalifa, who became the Emir of Bahrain in 1999 and proclaimed himself King of Bahrain in 2002, in fact becoming a constitutional monarch.

### 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.
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 the Iberian Peninsula (e.g. Spain). 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.
There was controversy for almost two centuries regarding allegations that Thomas Jefferson had fathered the children of his slave Sally Hemings. The controversy effectively began on September 1,1802 with an article by James Callender, printed in a Richmond newspaper. 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 seven known children, five 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.

↑ Haplogroup A0-T is also known as A-L1085 (and previously as A0'1'2'3'4).
↑ Haplogroup A1 is also known as A1'2'3'4.
↑ F-Y27277, sometimes known as F2'4, is both the parent clade of F2 and F4 and a child of F-M89.
↑ Haplogroup LT (L298/P326) is also known as Haplogroup K1.
↑ Between 2002 and 2008, Haplogroup T-M184 was known as "Haplogroup K2". That name has since been re-assigned to K-M526, the sibling of Haplogroup LT.
↑ Haplogroup K2b (M1221/P331/PF5911) is also known as Haplogroup MPS.
↑ Haplogroup K2b1 (P397/P399) is also known as Haplogroup MS, but has a broader and more complex internal structure.
↑ Haplogroup P (P295) is also klnown as K2b2.
↑ K-M2313*, which as yet has no phylogenetic name, has been documented in two living individuals, who have ethnic ties to India and South East Asia. In addition, K-Y28299, which appears to be a primary branch of K-M2313, has been found in three living individuals from India. See: Poznik op. cit.; YFull YTree v5.08, 2017, "K-M2335", and; PhyloTree, 2017, "Details of the Y-SNP markers included in the minimal Y tree" (Access date of these pages: 9 December 2017)
↑ Haplogroup S, as of 2017, is also known as K2b1a. (Previously the name Haplogroup S was assigned to K2b1a4.)
↑ Haplogroup M, as of 2017, is also known as K2b1b. (Previously the name Haplogroup M was assigned to K2b1d.) :
