Haplogroup R1 (Y-DNA)
Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479). Males carrying R-M173 in modern populations appear to comprise two subclades: R1a and R1b, which are found mainly in populations native to Eurasia (except East and Southeast Asia). R-M173 contains the majority of representatives of haplogroup R in the form of its subclades, R1a and R1b (, ). Structure Origins R1 and its sibling clade R2 (R-M79) are the only immediate descendants of Haplogroup R (R-M207). R is a direct descendant of Haplogroup P1 (P-M45), and a sibling clade, therefore, of Haplogroup Q (Q-M242). The origins of haplogroup R1 cannot currently be proved. According to the SNP-Tracker (as of May 2023) it evolved around 25 000 BP/23 000 BC in western Siberia between the southern Urals and Lake Balkhash. No examples of the basal subclade, R1* have ye ...

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Haplogroup R1b1
Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup. It is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia (e.g. the Bashkirs) and across the Sahel in Central Africa, namely: Cameroon, Chad, Guinea, Mauritania, Mali, Niger, Nigeria and Senegal (concentrated in parts of Chad with concentration in the Hausa Tribe and among the Chadic-speaking ethnic groups of Cameroon). The clade is also present at lower frequencies throughout Eastern Europe, Western Asia, Central Asia as well as parts of North Africa, South Asia and Central Asia. R1b has two primary branches: R1b1-L754 and R1b2-PH155. R1b1-L754 has two major subclades: R1b1a1b-M269, which predominates in Western Europe, and R1b1a2-V88, which is today common in parts of Central Africa. The other branch, R1b2-PH155, is so rare and widely dispersed that it is difficult to draw any conclusions about its origins. It has been found in Bahra ...

Ancient North Eurasian
In archaeogenetics, the term Ancient North Eurasian (ANE) refers to an ancestral component that represents the lineage of the people of the Mal'ta–Buret' culture () and populations closely related to them, such as the Upper Paleolithic individuals from Afontova Gora in Siberia. Genetic studies also revealed that the ANE are closely related to the remains of the preceding Yana culture (), which were dubbed as Ancient North Siberians (ANS), and which either are directly ancestral to the ANE, or both being closely related sister lineages. The ANE/ANS lineages both derive their ancestry from an admixture event between 'Ancient West Eurasians' (best represented by Upper Paleolithic Europeans such as Kostenki-14, c. 38,000 BP) and 'Ancient East Eurasians' (best represented by the Tianyuan man, c. 39,000 BP) during the Upper Paleolithic period. Around 20,000 to 25,000 years ago, a branch of Ancient North Eurasian people mixed with Ancient East Asians, which led to the emerge ...

Mal'ta–Buret' Culture
The Mal'ta–Buret' culture (also Maltinsko-buretskaya culture) is an archaeological culture of the Upper Paleolithic (generally dated to 24,000-23,000 BP but also sometimes to 15,000 BP). It is located roughly northwest of Lake Baikal, about 90 km to the northwest of Irkutsk, on the banks of the upper Angara River. The type sites are named for the villages of Mal'ta (), Usolsky District and Buret' (), Bokhansky District (both in Irkutsk Oblast). A boy whose remains were found near Mal'ta is usually known by the abbreviation MA-1 (or MA1). Discovered in the 1920s, the remains have been dated to 24,000 BP. According to research published since 2013, MA-1 belonged to the population of Ancient North Eurasians, who were genetically "intermediate between modern western Eurasians and Native Americans, but distant from east Asians", and partial genetic ancestors of Siberians, American Indians, and Bronze Age Yamnaya and Botai people of the Eurasian steppe.

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Paleolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans. It is followed by the Mesolithic. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago. It has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which may have contributed to the Neanderthal extinction, extinction of th ...

Paragroup
Paragroup is a term used in population genetics to describe lineages within a haplogroup that are not defined by any additional unique markers. In human Y-chromosome DNA haplogroups, paragroups are typically represented by an asterisk (*) placed after the main haplogroup. The term "paragroup" is a portmanteau of the terms paraphyletic Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In co ... haplogroup indicating that paragroups form paraphyletic subclades. Apart from the mutations that define the parent haplogroup, paragroups may not possess any additional unique markers. Alternatively paragroups may possess unique markers that have not been discovered. If a unique marker is discovered within a paragroup, the specific lineage is given a unique name and is moved out of the paragro ...

Lake Balkhash
Lake Balkhash, also spelt Lake Balqash (, , ), is a lake in southeastern Kazakhstan, one of the largest lakes in Asia and the 15th largest in the world. It is located in the eastern part of Central Asia and sits in the Balkhash-Alakol Basin, an endorheic (closed) basin. The basin drains seven rivers, the primary of which is the Ili, bringing most of the riparian inflow; others, such as the Karatal, bring surface and subsurface flow. The Ili is fed by precipitation, largely vernal snowmelt, from the mountains of China's Xinjiang region. The lake currently covers about . However, like the Aral Sea, it is shrinking due to diversion and extraction of water from its feeders. The lake has a narrow, quite central, strait. The lake's western part is fresh water and its eastern half is saline. The eastern part is on average 1.7 times deeper than the west. The largest shore city is named Balkhash and has about 66,000 inhabitants. Main local economic activities include mining, ore p ...

Southern Ural
Southern Ural (, ) encompasses the south, the widest part of the Ural Mountains, stretches from the river Ufa (near the village of Lower Ufaley) to the Ural River. From the west and east the Southern Ural is limited to the East European Plain, West Siberian Plain and the steppes near Aral Sea and Caspian Sea. Geography The relief of the Southern Urals is complex, with numerous valleys and parallel ridges directed south-west and meridionally. The range includes the Ilmensky Mountains separated from the main ridges by the Miass River. The maximum height is ( Mount Yamantau) and the width reaches . Other notable peaks lie along the Iremel mountain ridge (Bolshoy Iremel and Maly Iremel), the Nurgush, highest point , and the Nakas, highest point . The Southern Urals extend some up to the sharp westward bend of the Ural River and terminate in the wide Mugodzhar Hills Mugalzhar (), also known as Mugodzhar Hills or Mugodzhar Range (), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Siberia
Western Siberia or West Siberia ( rus, Западная Сибирь, p=ˈzapədnəjə sʲɪˈbʲirʲ; , ) is a region in North Asia. It is part of the wider region of Siberia that is mostly located in the Russia, Russian Federation, with a Southern part in Kazakhstan. It lies between the Ural (region), Ural region and the Yenisey, Yenisei River, which conventionally divides Siberia into two halves. Western Siberia covers an area of , nearly 80% of which is located within the West Siberian Plain. The largest rivers of the region are the Irtysh and the Ob (river), Ob. All major rivers of Western Siberia belong to the Kara Sea basin. The West Siberian petroleum basin is the largest hydrocarbon (petroleum and natural gas) basin in the world covering an area of about 2.2 million km2, and is also the largest oil and gas producing region in Russia. In Middle Ages, medieval times, parts of the region were part of the Golden Horde. After its gradual decline during the 15th century, the ...

Haplogroup Q-M242
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has two primary subclades: Q1/Q-L472 (also known as Q-MEH2) and Q2/Q-L275). These include numerous subclades that have been sampled and identified in males among modern populations. Q is the predominant Y-DNA haplogroup among Native Americans, Swati tribe and several peoples of Central Asia and Northern Siberia. Defining mutations The polymorphism M242, is a C→T transition residing in intron 1 (IVS-866) of the DBY gene and was discovered by Mark Seielstad et al. in 2003. The technical details of M242 are: :Nucleotide change: C to T :Position (base pair): 180 :Total size (base pairs): 366 :Forward 5′→ 3′: :Reverse 5′→ 3′: Other defining SNPs unique to Q-M242 include: FGC1752, F2603/M1020, L232/S432, M1115, Y2000/FGC1757, FGC6793, Y1984/FGC1753, Y1987/FGC1754/F6492, FGC7650(H), E337/L808/CTS3727/M1105, M1047(H), M1074, M1154, M1166, Y1972/FGC4603/F7839(H), Y2002/FGC1756/F6477(H), CTS7532/M1133, F ...

Haplogroup P-M45 (Y-DNA)
Haplogroup P1, also known as P-M45 and K2b2a, is a Y-chromosome DNA haplogroup in human genetics. Defined by the SNPs M45 and PF5962, P1 is a primary branch (subclade) of P (P-P295; K2b2). The only primary subclades of P1 are Haplogroup Q (Q-M242) and Haplogroup R (R-M207). These haplogroups now comprise most of the male lineages among Native Americans, Europeans, Central Asia and South Asia, among other parts of the world. P1 (M45) likely originated in Central Asia or Siberia, with basal P1* (P1xQ,R) now most common among individuals in Siberia and Central Asia.Miroslava Derenko et al 2005 Contrasting patterns of Y-chromosome variation in South Siberian populations from Baikal and Altai-Sayan regions Zgms.cm.umk.plE.
