Haplogroup JT (mtDNA)
Haplogroup JT is a human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup JT is descended from the macro-haplogroup R. It is the ancestral clade to the mitochondrial haplogroups J and T. Distribution JT (predominantly J) was found among the ancient Etruscans. The root level haplogroup JT* has been assigned to an ancient person found at the Colfiorito necropolis in Umbria in central Italy. The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site. One ancient individual carried a haplotype, which correlates with either the JT clade or the haplogroup H subclade H14b1 (1/9; 11%). Subclades Tree This phylogenetic tree of haplogroup JT subclades is based on the paper by Mannis van Oven and Manfred Kayser ''Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation'' and subsequent published research. *R2'JT **JT *** J *** T Health Maternally inherited ancient mtDNA varia ...

West Asia
West Asia (also called Western Asia or Southwest Asia) is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the island of Cyprus, the Sinai Peninsula and the South Caucasus. The region is separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. West Asia contains the majority of the similarly defined Middle East. The ''Middle East'' is a political term invented by Western geographers that has ...

Haplogroup Pre-JT (mtDNA)
Haplogroup pre-JT is a human mitochondrial DNA haplogroup (mtDNA). It is also called R2'JT. Origin Haplogroup pre-JT is a descendant of the haplogroup R. It is characterised by the mutation T4216C. The pre-JT clade has two direct descendant lineages, haplogroup JT and haplogroup R2. Distribution According to YFull MTree, haplogroup R2'JT has allegedly been sequenced in at least three individuals, among whom one came from ancient Egypt and one from modern Denmark. However, Ian Logan mutationally interpreted the Denmark sample as being a member of T1a. One carrier of haplogroup R2'JT was found in an in-depth study of "108 Scandinavian Neolithic individuals". Subclades Its major subclade is Haplogroup JT, which further divides into Haplogroup J and Haplogroup T. Its other subclade is Haplogroup R2, which has such branches as R2a, R2b, and R2c.

Haplogroup J (mtDNA)
Haplogroup J is a human mitochondrial DNA (mtDNA) haplogroup. The clade derives from the haplogroup JT, which also gave rise to haplogroup T. Within the field of medical genetics, certain polymorphisms specific to haplogroup J have been associated with Leber's hereditary optic neuropathy. as well as Sudanese Copts (10.3% J1a; 10.3% J2), Sudanese Fulani (10.7% J1b), Meseria (6.7% J1b), Arakien (5.9% J1b), Egyptians (5.9%), Mozabite Berbers (3.53%), Sudanese Hausa (2.9% J1b), Zenata Berbers (2.74%), Beja (2.1% J1b), and Reguibate Sahrawi (0.93%).

Haplogroup T (mtDNA)
Haplogroup T is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated around 25,100 years ago in the Near East. Origins Mitochondrial clade T derives from the haplogroup JT, which also gave rise to the mtDNA haplogroup J. The T maternal clade is thought to have emanated from the Near East. Distribution The basal haplogroup T* is found among Algerians in Oran (1.67%) and Reguibate Sahrawi (0.93%).S5 Table/ref> It is also distributed among the Soqotri (1.2%). Haplogroup T is present at low frequencies throughout Western and Central Asia and Europe, with varying degrees of prevalence and certainly might have been present in other groups from the surrounding areas. T is found in approximately 10% of native Europeans. It is also common among modern day Iranians. Based on a sample of over 400 modern day Iranians, the T haplogroup represents roughly 8.3% of the population (about 1 out of 12 individuals), with the more specific T1 subtype constituting ...

Human Mitochondrial DNA Haplogroup
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup R (mtDNA)
Haplogroup R is a widely distributed Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of archaeogenetics of sub-Saharan Africa, sub-Saharan Africa. Haplogroup R is a descendant of the macro-Haplogroup N (mtDNA), haplogroup N. Among the R clade's descendant haplogroups are Haplogroup B (mtDNA), B, haplogroup U (mtDNA), U (and thus haplogroup K (mtDNA), K), Haplogroup F (mtDNA), F, Haplogroup R0 (mtDNA), R0 (and thus Haplogroup HV (mtDNA), HV, Haplogroup H (mtDNA), H, and Haplogroup V (mtDNA), V), and Haplogroup JT (mtDNA), JT (the ancestral haplogroup of Haplogroup J (mtDNA), J and Haplogroup T (mtDNA), T). Origin Soares et al. (2009) estimate the age of haplogroup R at roughly 50,000 to 70,000 years ago. This is consistent with an emergence in the course of the Southern Dispersal out of East A ...

Etruscans
The Etruscan civilization ( ) was an ancient civilization created by the Etruscans, a people who inhabited Etruria in List of ancient peoples of Italy, ancient Italy, with a common language and culture, and formed a federation of city-states. After adjacent lands had been conquered its territory covered, at its greatest extent, roughly what is now Tuscany, western Umbria and northern Lazio, as well as what are now the Po Valley, Emilia-Romagna, south-eastern Lombardy, southern Veneto and western Campania. A large body of literature has flourished on the origins of the Etruscans, but the consensus among modern scholars is that the Etruscans were an indigenous population. The earliest evidence of a culture that is identifiably Etruscan dates from about 900 BC. This is the period of the Iron Age Villanovan culture, considered to be the earliest phase of Etruscan civilization, which itself developed from the previous late Bronze Age Proto-Villanovan culture in the same region, p ...

Umbria
Umbria ( ; ) is a Regions of Italy, region of central Italy. It includes Lake Trasimeno and Cascata delle Marmore, Marmore Falls, and is crossed by the Tiber. It is the only landlocked region on the Italian Peninsula, Apennine Peninsula. The regional capital is Perugia. The region is characterized by hills, mountains, valleys and historical towns such as the university centre of Perugia, Assisi (a World Heritage Site associated with Francis of Assisi, St. Francis of Assisi), Terni, Norcia, Città di Castello, Gubbio, Spoleto, Orvieto, Todi, Castiglione del Lago, Narni, Amelia, Umbria, Amelia, Spello and other small cities. Geography Umbria is bordered by Tuscany to the west and the north, Marche to the east and Lazio to the south. Partly hilly and mountainous, and partly flat and fertile owing to the valley of the Tiber, its topography includes part of the central Apennine Mountains, Apennines, with the highest point in the region at Monte Vettore on the border of Marche, a ...

Iberomaurusian
The Iberomaurusian is a backed bladelet lithic industry found near the coasts of Morocco, Algeria, and Tunisia. It is also known from a single major site in Libya, the Haua Fteah, where the industry is known as the Eastern Oranian.The "Western Oranian" would refer to the Iberomaurusian in Morocco, Algeria, and Tunisia, but this expression is seldom used. The Iberomaurusian seems to have appeared around the time of the Last Glacial Maximum (LGM), somewhere between c. 25,000 and 23,000 cal BP. It would have lasted until the early Holocene, c. 11,000 cal BP. The name "Iberomaurusian" means "of Iberia and Mauretania", the latter being a Latin name for northwest Africa. Paul Maurice Pallary (1909) coined this termPallary, P., 1909.

Epipaleolithic
In archaeology, the Epipalaeolithic or Epipaleolithic (sometimes Epi-paleolithic etc.) is a period occurring between the Upper Paleolithic and Neolithic during the Stone Age. Mesolithic also falls between these two periods, and the two are sometimes confused or used as synonyms. More often, they are distinct, referring to approximately the same period of time in different geographic areas. Epipaleolithic always includes Epipalaeolithic Near East, this period in the Levant and, often, the rest of the Near East. It sometimes includes parts of Southeast Europe, where Mesolithic is much more commonly used. Mesolithic very rarely includes the Levant or the Near East; in Europe, Epipalaeolithic is used, though not very often, to refer to the early Mesolithic. The Epipalaeolithic has been defined as the "final Upper Palaeolithic industries occurring at the end of the final Last glacial period, glaciation which appear to merge technologically into the Mesolithic". The period is general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taforalt
Taforalt, or Grotte des Pigeons, is a cave in the province of Berkane, Aït Iznasen region, Morocco, possibly the oldest cemetery in North Africa. It contained at least 34 Iberomaurusian adolescent and adult human skeletons, as well as younger ones, from the Upper Palaeolithic between 15,100 and 14,000 calendar years ago. There is archaeological evidence for Iberomaurusian occupation at the site between 23,200 and 12,600 calendar years ago, as well as evidence for Aterian occupation as old as 85,000 years. Site description La Grotte des Pigeons is a cave in eastern Morocco near the village of Taforalt. Human occupation and natural processes in the cave have produced a thick sequence of archaeological layers dating between at least 85,000 and 10,000 years ago. These occupation layers include pre- Mousterian, Aterian, and Iberomaurusian lithic industries, plus an unusual non-Levallois industry between the Aterian and the Iberomaurusian dating to c. 24,500 cal BP.

Haplogroup H (mtDNA)
Haplogroup H is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in West Asia, near present-day Syria, around 20,000 to 25,000 years ago. A specimen found in South Italy from 28000 years ago, in Paglicci Cave, was once believed to indicate haplogroup H, but researchers now recognize that CRS HVR1 also appears in U or HV, because there are no HVR1 mutations that separate CRS from the haplogroup R founder. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM). It first expanded in the northern Near East and Southern Caucasus, and later migrations from Iberia suggest that the clade reached Europe before the Last Glacial Maximum. The haplogroup has also spread from West Asia to parts of Africa, Siberia and Inner Asia. Today, around 40% of all maternal lineages in Europe belong to haplogroup H.
