Haplogroup C (mtDNA)
In human mitochondrial genetics, Haplogroup C is a human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup C is believed to have arisen in East Asia some 24,000 years before present. It is a descendant of the haplogroup M. Haplogroup C shares six mutations downstream of the MRCA of haplogroup M with haplogroup Z and five mutations downstream of the MRCA of haplogroup M with other members of haplogroup M8. This macro-haplogroup is known as haplogroup M8'CZ or simply as haplogroup M8. Distribution Haplogroup C is found in Northeast Asia (including Siberia) and the Americas. In Eurasia, Haplogroup C is especially frequent among populations of arctic Siberia, such as Nganasans, Dolgans, Yakuts, Evenks, Evens, Yukaghirs, and Koryaks. Haplogroup C is one of five mtDNA haplogroups found in the indigenous peoples of the Americas, the others being A, B, D, and X. The subclades C1b, C1c, C1d, and C4c are found in the first people of the Americas. C1a is found only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Mitochondrial DNA (mtDNA) 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 mitochond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yukaghir People
The Yukaghirs, or Yukagirs ( (), ), are a Siberian ethnic group in the Russian Far East, living in the basin of the Kolyma River. Geographic distribution The Tundra Yukaghirs live in the Lower Kolyma region in the Sakha Republic; the Taiga Yukaghirs in the Upper Kolyma region in the Sakha Republic and in Srednekansky District of Magadan Oblast. By the time of Russian colonization in the 17th century, the Yukaghir tribal groups occupied territories from the Lena River to the mouth of the Anadyr River. The number of the Yukaghirs decreased between the 17th and 19th centuries due to epidemics, internecine wars and Tsarist colonial policy which may have included genocide against the sedentary hunter-fisher Anaouls. Some of the Yukaghirs have assimilated with the Yakuts, Evens, and Russians. Currently, Yukaghirs live in the Sakha Republic and the Chukotka Autonomous Okrug of the Russian Federation. According to the 2002 Census, their total number was 1,509 people, up from 1,112 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tofalars
The Tofalar (also Karagas or Tofa; Тофалары, тофа (tofa) in Russian) people are a Turkic people who live in Tofalariya, in the southwestern part of Nizhneudinsky District, Irkutsk Oblast of Russia. The Tofalar population is highly mixed with Russians due to the presence of Russian settlers and high rates of intermarriage. Prior to Soviet rule, the Tofalar led a nomadic lifestyle in the taiga, engaging in reindeer husbandry and hunting. Afterwards, they were resettled by the Soviet government and forced to adopt sedentarism and were discouraged from practicing hunting and shamanism. According to the 2010 census, there were 762 Tofalar in Russia. Etymology Tofalar is an endonym and contains the Turkic plural suffix -lar, thus translating to "Tofas"; Tofalar means "people of the deer." The Tofalar were formerly known as 'Karagas,' which was derived from the name of one particular Tofalar clan, the Kara-Kash or Karahaash. History Origins The ancestors of the ...

East
East is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or " dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'.

Stony Tunguska River
The Podkamennaya Tunguska (, literally ''Tunguska under the stones''; , Ket: Ӄо’ль) also known as ''Middle Tunguska'' or ''Stony Tunguska'', is a river in Krasnoyarsk Krai, Russia. History In 1908, an asteroid impacted near the river and later became known as the Tunguska event. Hydrology The river's nutrition is mainly snow (60%); rain and groundwater nutrition account for 16 and 24%, respectively. The flood lasts from the beginning of May to the end of June, in the lower reaches until the beginning of July. From July to October, there is a summer low, interrupted by a rise in the level to 5.5 m during floods, which can be from one to four per year. The average annual water consumption at the mouth is 1587.18 m3/s, during summer floods it reaches 35,000 m3/s. Ice phenomena have been occurring since mid-October, the autumn ice drift of 7-16 days is accompanied by the formation of ice jams. The ice age is from the end of October to the middle of May.

Aconcagua Mummy
The Aconcagua mummy is an Incan ''capacocha'' mummy of a seven-year-old boy, dated to around the year 1500. The mummy is well-preserved, due to the extreme cold and dry conditions of its high altitude burial location. The frozen mummy was discovered by hikers in 1985 at on Aconcagua in Mendoza, Argentina. Discovery In 1985, the body of the Aconcagua mummy was located by mountaineers at the bottom of Pirámide Mountain, the southwestern portion of the Aconcagua Mountain. Upon its discovery, the hikers contacted local authorities, allowing professionals to excavate the mummy. Scientific analysis Burial practices The Aconcagua mummy was buried inside a semicircular stone structure and found covered in vomit, red pigment, and fecal remains. The body was wrapped in textiles in a style derived from central coastal Peru. Although the style of the textiles the boy was wrapped in are dated to coastal Peru, isotopic evidence suggests that the boy was likely raised in the Highlands. S ...

Pre-Columbian Trans-oceanic Contact
Pre-Columbian transoceanic contact theories, many of which are speculative, propose that visits to the Americas, interactions with the Indigenous peoples of the Americas, or both, were made by people from elsewhere prior to Christopher Columbus's first voyage to the Caribbean in 1492. Studies between 2004 and 2009 suggest the possibility that the earliest human migrations to the Americas may have been made by boat from Beringia and travel down the Pacific coast, contemporary with and possibly predating land migrations over the Beringia land bridge, which during the glacial period joined what today are Siberia and Alaska. Apart from Norse contact and settlement, whether transoceanic travel occurred during the historic period, resulting in pre-Columbian contact between the settled American peoples and voyagers from other continents, is vigorously debated. Only a few cases of pre-Columbian contact are widely accepted by mainstream scientists and scholars. Yup'ik and Aleut peo ...

Haplogroup X (mtDNA)
Haplogroup X is a human mitochondrial DNA (mtDNA) haplogroup. It is found in North America, Europe, Western Asia, North Africa, and the Horn of Africa. Haplogroup X diverged from haplogroup N roughly 30,000 years ago (just prior to or during the Last Glacial Maximum). It is in turn ancestral to subclades X2 and X1, which arose 16-21 thousand and 14-24 thousand years ago, respectively. Distribution Haplogroup X is found in approximately 2% of native Europeans, and 13% of all native North Americans. Additionally, the Haplogroup is present in around 3% of Assyrians, with high concentrations in Erzurum, Turkey as well. Notably, the haplogroup is especially common, at 14.3%, among the natives of Bahariya Oasis ( Western Desert, Egypt. The X1 subclade is much less frequent, and is largely restricted to North Africa, the Horn of Africa and the Near East. Subclade X2 appears to have undergone extensive population expansion and dispersal around or soon after the Last Glacial Maximum ...

Haplogroup D (mtDNA)
In human mitochondrial genetics, Haplogroup D is a human mitochondrial DNA (mtDNA) haplogroup. It is a descendant haplogroup of haplogroup M, thought to have arisen somewhere in East Asia, between roughly 60,000 and 35,000 years ago (in the Late Pleistocene, before the Last Glacial Maximum and the settlement of the Americas). estimated at ( 95% CI) in: In contemporary populations, it is found especially in Central and Northeast Asia. Haplogroup D (more specifically, subclade D4) is one of five main haplogroups found in the indigenous peoples of the Americas, the others being A, B, C, and X. Among the Nepalese population, haplogroup D is the most dominant maternal lineage in Tamang (26.1%) and Magar (24.3%). Subclades There are two principal branches, D4 and D5'6. D1, D2 and D3 are subclades of D4. D4 D1 is a basal branch of D4 that is widespread and diverse in the Americas. Subclades D4b1, D4e1, and D4h are found both in Asia and in the Americas and are thus of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
