Poltavka Culture
Poltavka culture () was an early to middle Bronze Age archaeological culture which flourished on the Volga- Ural steppe and the forest steppe in 2800—2200 BCE. The Poltavka culture emerged as an eastern outgrowth of the Yamnaya culture, neighboring the Catacomb culture, another Yamnaya successor, in the west. It has been considered ancestral to later cultures that are identified as Indo-Iranian. The Poltavka culture influenced the later emergence of the Potapovka culture, Abashevo culture, Sintashta culture and Srubnaya culture. Origins The Poltavka culture emerged ca. 2800 BC, as an eastern successor of the Yamnaya culture. The western successor of the Yamnaya culture was the Catacomb culture. Along with the Sredny Stog culture, the Yamnaya culture and the Catacomb culture, the Poltavka culture is among the cultures of the Pontic steppe sharing archaeological characteristics with the Afanasievo culture of the eastern steppe. Distribution The Poltavka culture fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end of ...

Steppe Ancestry
In archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Eneolithic steppe around the turn of the 5th millennium BCE, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary European and South Asian populations. This ancestry is often referred to as Yamnaya Ancestry, Yamnaya-Related Ancestry, Steppe Ancestry or Steppe-Related Ancestry. Western Steppe Herders are considered descended from Eastern Hunter-Gatherers (EHGs) who reproduced with Caucasus Hunter-Gatherers (CHGs), and the WSH component is analysed as an admixture of EHG and CHG ancestral components in roughly equal proportions, with the majority of the Y-DNA haplogroup contribution from EHG males. The Y-DNA haplogroups of Western Steppe Herder males ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BioRxiv
bioRxiv (pronounced "bio-archive") is an open access preprint repository for the biological sciences co-founded by John Inglis and Richard Sever in November 2013. It is hosted by the Cold Spring Harbor Laboratory (CSHL). As preprints, papers hosted on bioRxiv are not peer-reviewed, but undergo basic screening and checked against plagiarism. However, peer reviews from other sources may be posted alongside preprints. Moreover, readers may post comments. It has been measured that two thirds of the papers posted in bioRxiv are later published in peer-reviewed journals. A service called Rxivist parses the metadata of preprints from bioRxiv, and combines it with data from Twitter allowing to detect trending preprints. MedRxiv, and its sister site, bioRxiv, have been major sources for the dissemination of COVID-19 research. History BioRxiv was inspired by and intends to complement the arXiv repository, which mostly focuses on mathematics, physics and connected disciplines, launc ...

Haplogroup R1a
Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to southern Siberia and South Asia. While R1a originated c. 22,000 to 25,000 years ago, its subclade M417 (R1a1a1) diversified c. 5,800 years ago. The place of origin of the subclade plays a role in the debate about the origins of Proto-Indo-Europeans. The SNP mutation R-M420 was discovered after R-M17 (R1a1a), which resulted in a reorganization of the lineage in particular establishing a new paragroup (designated R-M420*) for the relatively rare lineages which are not in the R-SRY10831.2 (R1a1) branch leading to R-M17. Origins R1a origins The split of R1a (M420) is computed to c. 22,000 or 25,000 years ago, which is the time of the last glacial maximum. A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling ...

Haplogroup R1b
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 pockets of Central Africa (e.g. parts of Chad and among the Chadic-speaking minority ethnic groups of Cameroon). The clade is also present at lower frequencies throughout Eastern Europe, Western 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 R1b1b-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 Bahrain, India, Nepal, Bhutan, Ladakh, Tajikistan, Turkey, and Western China. According to ancient DNA studies, most R1a and R1b lineages would ha ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Kurgans
A kurgan is a type of tumulus constructed over a grave, often characterized by containing a single human body along with grave vessels, weapons and horses. Originally in use on the Pontic–Caspian steppe, kurgans spread into much of Central Asia and Eastern, Southeast, Western and Northern Europe during the 3rd millennium BC. The earliest kurgans date to the 4th millennium BC in the Caucasus, and a part of researchers associate these with the Indo-Europeans. Kurgans were built in the Eneolithic, Bronze, Iron, Antiquity and Middle Ages, with ancient traditions still active in Southern Siberia and Central Asia. Etymology According to the Etymological dictionary of the Ukrainian language the word "kurhan" is borrowed directly from the "Polovtsian" language ( Kipchak, part of the Turkic languages) and means: fortress, embankment, high grave. The word has two possible etymologies, either from the Old Turkic root ''qori-'' "to close, to block, to guard, to protect", or ''q ...

Maykop Culture
The Maykop culture (, , scientific transliteration: ''Majkop,''), c. 3700 BC– 3000 BC, was a major Bronze Age archaeological culture in the western Caucasus region. It extends along the area from the Taman Peninsula at the Kerch Strait to near the modern border of Dagestan and southwards to the Kura River. The culture takes its name from a royal burial, the Maykop kurgan in the Kuban River valley. According to genetic studies on ancient DNA published in 2018, the Maykop population came from the south, from Imereti, and was descended from the Chalcolithic farmers known as Darkveti-Meshoko who first colonized the north side of the Caucasus. Maykop is therefore the "ideal archaeological candidate for the founders of the Northwest Caucasian language family". Territory In the south, the Maykop culture bordered the approximately contemporaneous Kura-Araxes culture (3500—2200 BC), which extends into the Armenian Plateau and apparently influenced it. To the north is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samara Culture
The Samara culture was an Eneolithic (Copper Age) culture that flourished around the turn of the 5th millennium BCE, at the Samara Bend of the Volga River (modern Russia). The Samara culture is regarded as related to contemporaneous or subsequent prehistoric cultures of the Pontic–Caspian steppe, such as the Khvalynsk, Repin and Yamna (or Yamnaya) cultures. The Proto-Indo-European homeland is often linked to one or more of these cultures. Place and time The Samara culture was an Eneolithic culture of the early 5th millennium BCE at the Samara bend region of the middle Volga, at the northern edge of the steppe zone. It was discovered during archaeological excavations in 1973 near the village of Syezzheye (Съезжее) near Bogatoye. Related sites are Varfolomeyevka on the Russian-Kazakh border (5500 BCE), which has parallels in Dzhangar ( Kalmykia), and Mykol'ske, on the Dnieper. The later stages of the Samara culture are contemporaneous with its successor culture in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khvalynsk
Khvalynsk ( rus, Хвалы́нск, p=xvɐˈlɨnsk) is a river port town in Saratov Oblast, Russia, located by the Volga River. Population: 16,000 (1974). It is located on the right bank of the Volga, at the foot of the Khvalynsk Mountains, northeast of Saratov and southwest of Samara. The place name stems from the old Russian name of the Caspian Sea: Хвалынское море, or "Khvalyn Sea". The latter is derived from the name "Khwalis" for the inhabitants of Khwarezm. The town is the namesake of the Khvalynsk Hills and Khvalynsk culture. History It was founded in 1556 as a Russian outpost on the Sosnovy Island on the Volga. In 1606, the whole settlement was relocated to the spot of today's Khvalynsk and came to be known as Sosnovy Ostrov (, lit. ''pine island''). In 1780, the settlement was granted uyezd town status and renamed Khvalynsk. In the 18th–19th centuries, Khvalynsk was known as a local center for trading bread and agricultural produce. It was als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Burial
Horse burial is the practice of burying a horse as part of the ritual of human burial, and is found among many Indo-European speaking peoples and others, including Chinese and Turkic peoples. The act indicates the high value placed on horses in the particular cultures and provides evidence of the migration of peoples with a horse culture. Human burials that contain other livestock are rare; in Britain, for example, 31 horse burials have been discovered but only one cow burial, unique in Europe. This process of horse burial is part of a wider tradition of horse sacrifice. An associated ritual is that of chariot burial, in which an entire chariot, with or without a horse, is buried with a dead person. Background and detail The horse carries great symbolic meaning in human cultures (see horse worship). In Celtic and Germanic cultures, for instance, the horse "could be associated with the journeying sun", and horses were deified and used in divination, but Celtic horse sacrifice i ...
