Haplogroup Q-M3 (Y-DNA)
Haplogroup Q-M3 (Y-DNA) is a Y-chromosome DNA haplogroup. Haplogroup Q-M3 is a subclade of Haplogroup Q-L54. Haplogroup Q-M3 was previously known as Haplogroup Q3; currently Q-M3 is Q1b1a1a below Q1b-M346. In 1996 the research group at Stanford University headed by Dr. Peter Underhill first discovered the SNP that was to become known as M3. At the time, it was called DYS191. Later studies completed the genetic bridge by determining that Q-M3 was related to Q-M242-bearing populations who traveled through Central Asia to East Asia. Origin and distribution Haplogroup Q-M3 is one of the Y-Chromosome haplogroups linked to the indigenous peoples of the Americas (over 90% of indigenous people in Meso & South America). Today, such lineages also include other Q-M242 branches ( Q-M346, Q-L54, Q-P89.1, Q-NWT01, and Q-Z780), haplogroup C-M130 branches ( C-M217 and C-P39), and R-M207, which are almost exclusively found in the North America. Haplogroup Q-M3 is defined by the presence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beringia
Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72 degrees north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States and the Yukon in Canada. The area includes land lying on the North American Plate and Siberian land east of the Chersky Range. At certain times in prehistory, it formed a land bridge that was up to wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling approximately . Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, St. Matthew Island, and King Island. The term ''Berin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup R-M207 (Y-DNA)
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. According to geneticist Spencer Wells, haplogroup K, from which haplogroups P and Q descend, originated in the Middle East or Central Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan." However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they coul ...

Haplogroup Q-L54 (Y-DNA)
Haplogroup Q-L54 is a subclade of Y-DNA haplogroup Q-L53. Q1a3a-L54 is defined by the presence of the L54 Single Nucleotide Polymorphism (SNP). Distribution Q-L54 has descendants across Western and Central Europe, the North and East of Asia, and the Americas. It includes two of the major pre-Columbian paternal lineages in the Americas: Q-M3 and Q-M971. The boy Anzick-1, who lived 12,600 years ago and was found in the state of Montana, has a Y-chromosome that refers to haplogroup Q-M971 (Q-L54*(xM3)). Q-L54 descendant lines also include two Eurasian paternal lineages, the Central Asian Q-L330 lineage and the Scandinavian Q-L804. Q-L330 is also found in some men with Romaniote Jewish paternal lines from Greece. Q-L804 is Scandinavian and the TMRCA is just over 3000 years. Haplogroup Q‐L54 is dominant in two North Siberian populations, the Kets and Selkups, with frequencies of 97.7% and 66.7%, respectively. Associated SNP's Q-L54 is currently defined by the L54 SNP alone. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-nucleotide Polymorphism
In genetics, a single-nucleotide polymorphism (SNP ; plural SNPs ) is a germline substitution of a single nucleotide at a specific position in the genome. Although certain definitions require the substitution to be present in a sufficiently large fraction of the population (e.g. 1% or more), many publications do not apply such a frequency threshold. For example, at a specific base position in the human genome, the G nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – G or A – are said to be the alleles for this specific position. SNPs pinpoint differences in our susceptibility to a wide range of diseases, for example age-related macular degeneration (a common SNP in the CFH gene is associated with increased risk of the disease) or nonalcoholic fatty liver disease (a SNP in the PNPLA3 gene is associated wit ...

David C
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Ticuna
The Ticuna (also Magüta, Tucuna, Tikuna, or Tukuna) are an indigenous people of Brazil (36,000'')'', Colombia (6,000), and Peru (7,000). They are the most numerous tribe in the Brazilian Amazon. History The Ticuna were originally a tribe that lived far away from the rivers and whose expansion was kept in check by neighboring people. Their historical lack of access to waterways and their practice of endogamy has led to the Ticuna being culturally and genetically distinct from other Amazonian tribes. The first contact with outsiders occurred on the colonization of Brazil when a Portuguese fleet exploring the Amazon came into contact with the Ticuna. Sustained contact with the Portuguese and other outsiders began in 1649. Since the Ticuna lived relatively inland compared to other tribes they were less affected by the diseases and violence caused by colonialism, hence why the Ticuna today have the largest population of any Amazonian people. When the Europeans initiated warfare with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples Of South America
The Indigenous peoples of South America or South American Indigenous peoples, are the pre-Colombian peoples of South America and their descendants. These peoples contrast with South Americans of European ancestry and those of African descent. In Spanish, Indigenous people are often referred to as ''indígenas'' or ''pueblos indígenas'' (lit. Indigenous peoples). They may also be called ''pueblos nativos'' or ''nativos'' (lit. Native peoples). The term ''aborigen'' (lit. aborigine) is used in Argentina and ''pueblos aborígenes'' (lit. aboriginal peoples) is commonly used in Colombia. The English term "Amerindian" (short for "Indians of the Americas") is often used in the Guianas. Latin Americans of mixed European and Indigenous descent are usually referred to as mestizos (Spanish) and mestiços (Portuguese). While those of mixed African and Indigenous ancestry are referred to as zambos. It is believed that the first human populations of South America either arrived from ...

Evens
The Evens ( eve, эвэн; pl. , in Even and , in Russian; formerly called ''Lamuts'') are a people in Siberia and the Russian Far East. They live in regions of the Magadan Oblast and Kamchatka Krai and northern parts of Sakha east of the Lena River. According to the 2002 census, there were 19,071 Evens in Russia. According to the 2010 census, there were 22,383 Evens in Russia. They speak their own language called Even, one of the Tungusic languages. The Evens are close to the Evenks by their origins and culture. Officially, they have been considered to be of Orthodox faith since the 19th century, though the Evens have retained some pre-Christian practices, such as shamanism. Traditional Even life is centred upon nomadic pastoralism of domesticated reindeer, supplemented with hunting, fishing and animal-trapping. There were 104 Evens in Ukraine, 19 of whom spoke Even. (Ukr. Cen. 2001) History The ancestors of the Evens were believed to have migrated from the Transbai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberian
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...

Kennewick Man
Kennewick Man and Ancient One are the names generally given to the skeletal remains of a prehistoric Paleoamerican man found on a bank of the Columbia River in Kennewick, Washington, on July 28, 1996. It is one of the most complete ancient skeletons ever found. Radiocarbon tests on bone have shown it to date from 8,900 to 9,000 calibrated years before present,Preston, Douglas (September 2014)"The Kennewick Man Finally Freed to Share His Secrets" '' Smithsonian''. Retrieved November 8, 2014. but it was not until 2013 that ancient DNA analysis techniques had improved enough to shed light on the remains. The discovery led to controversy among scientists as well as Native American tribes for more than a decade. The Umatilla people and other tribes demanded that the remains be returned for reburial under the federal Native American Graves Protection and Repatriation Act (NAGPRA). The law was designed to return human remains and cultural objects which had long been unlawfully obtai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
