Genetics And Archaeogenetics Of South Asia
Genetics and archaeogenetics of South Asia is the study of the genetics and archaeogenetics of the ethnic groups of South Asia. It aims at uncovering these groups' genetic histories. The geographic position of the Indian subcontinent makes its biodiversity important for the study of the early dispersal of anatomically modern humans across Asia. Based on mitochondrial DNA (mtDNA) variations, genetic unity across various South Asian subpopulations have shown that most of the ancestral nodes of the phylogenetic tree of all the mtDNA types originated in the subcontinent. Conclusions of studies based on Y chromosome variation and autosomal DNA variation have been varied. The genetic makeup of modern South Asians can be described at the deepest level as a combination of West Eurasian (related to ancient and modern people in Europe and West Asia) ancestries with divergent East Eurasian ancestries. The latter primarily include a proposed indigenous South Asian component (termed ''Anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Asia Non Political
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant). South is sometimes abbreviated as S. Navigation By convention, the ''bottom or down-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Plateau
The Iranian plateau or Persian plateau is a geological feature spanning parts of the Caucasus, Central Asia, South Asia, and West Asia. It makes up part of the Eurasian plate, and is wedged between the Arabian plate and the Indian plate. The plateau is situated between the Zagros Mountains to the west, the Caspian Sea and the Köpet Dag to the north, the Armenian Highlands and the Caucasus Mountains to the northwest, the Strait of Hormuz and the Persian Gulf to the south, and the Indian subcontinent to the southeast. As a historical region, it includes Parthia, Media, Persis, and some of the previous territories of Greater Iran."Old Iranian Online" , University of Texas College of Liberal Arts (retrieved 10 February 2007) The Zagros form the plateau's western boundary, and its eastern slopes may also ...

Western Steppe Herder
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 Chalcolithic steppe around the start of the 5th millennium BC, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Repin, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary populations of Europe, Central Asia, South Asia and West Asia. This ancestry is often referred to as Yamnaya ancestry, Yamnaya-related ancestry, Steppe ancestry or Steppe-related ancestry. Western Steppe Herders are considered to be descended from a merger between Eastern Hunter-Gatherers (EHGs) and Caucasus Hunter-Gatherers (CHGs). The WSH component is modeled 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 haplog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SNPs
In genetics and bioinformatics, 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, a G nucleotide present at a specific location in a reference genome may be replaced by an A in a minority of individuals. The two possible nucleotide variations of this SNP – G or A – are called alleles. SNPs can help explain differences in susceptibility to a wide range of diseases across a population. For example, a common SNP in the CFH gene is associated with increased risk of age-related macular degeneration. Differences in the severity of an illness or response to treatments may also be manifestations of genetic variations caused by SNPs. For example, two common SNPs in the ''A ...

Munda Languages
The Munda languages are a group of closely related languages spoken by about eleven million people in India, Bangladesh and Nepal. Historically, they have been called the Kolarian languages. They constitute a branch of the Austroasiatic language family, which means they are more distantly related to languages such as the Mon and Khmer languages, to Vietnamese, as well as to minority languages in Thailand and Laos and the minority Mangic languages of South China. Bhumij, Ho, Mundari, and Santali are notable Munda languages. The family is generally divided into two branches: North Munda, spoken in the Chota Nagpur Plateau of Jharkhand, Chhattisgarh, Bihar, Odisha and West Bengal, as well as in parts of Bangladesh and Nepal, and South Munda, spoken in central Odisha and along the border between Andhra Pradesh and Odisha. North Munda, of which Santali is the most widely spoken and recognised as an official language in India, has twice as many speakers as South Munda. A ...

Northeast India
Northeast India, officially the North Eastern Region (NER), is the easternmost region of India representing both a geographic and political Administrative divisions of India, administrative division of the country. It comprises eight States and union territories of India, states—Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura (commonly known as the "Seven Sisters"), and the "brother" state of Sikkim. The region shares an international border of 5,182 kilometres (3,220 mi) (about 99 per cent of its total geographical boundary) with several neighbouring countries – it borders China to the north, Myanmar to the east, Bangladesh to the south-west, Nepal to the west, and Bhutan to the north-west. It comprises an area of , almost 8 per cent of that of India. The Siliguri Corridor connects the region to the Mainland India, rest of mainland India. The states of North Eastern Region are officially recognised under the North Eastern Council (NEC), co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayan Foothills
The Himalayas, or Himalaya ( ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the Earth's highest peaks, including the highest, Mount Everest. More than 100 peaks exceeding elevations of above sea level lie in the Himalayas. The Himalayas abut on or cross territories of six countries: Nepal, China, Pakistan, Bhutan, India and Afghanistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo– Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have profoundly shaped the cultures of So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khasian Languages
The Khasic or Khasian languages are a family of Austroasiatic languages native to the Shillong Plateau and spoken by the Khasi, Pnar and other related ethnic groups. Most of them reside in the northeastern Indian state of Meghalaya where Khasi speakers form a plurality of the population. Smaller Khasic-speaking pockets are found in Assam, Manipur, Mizoram and Sylhet Division of Bangladesh. Languages Sidwell (2018: 27–31) classifies the Khasian languages as follows. *Proto-Khasian **War (Amwi, Mnar) **Proto–Pnar-Khasi-Lyngngam *** Lyngngam (former Garo-speakers) *** **** Pnar (Jaintia) **** Khasi **** Maharam (Maram) Varieties called ''Bhoi'' are dialects of both Pnar and Khasi. External relationships Paul Sidwell (2011) suggests that Khasian is closely related to Palaungic, forming a Khasi–Palaungic branch. The following eight Khasian- Palaungic isoglosses have been identified by Sidwell (2018: 32). Lexical innovations Sidwell (2018: 23) lists the following ...

Tibeto-Burmese
The Tibeto-Burman languages are the non- Sinitic members of the Sino-Tibetan language family, over 400 of which are spoken throughout the Southeast Asian Massif ("Zomia") as well as parts of East Asia and South Asia. Around 60 million people speak Tibeto-Burman languages. The name derives from the most widely spoken of these languages, Burmese and the Tibetic languages, which also have extensive literary traditions, dating from the 12th and 7th centuries respectively. Most of the other languages are spoken by much smaller communities, and many of them have not been described in detail. Though the division of Sino-Tibetan into Sinitic and Tibeto-Burman branches (e.g. Benedict, Matisoff) is widely used, some historical linguists criticize this classification, as the non-Sinitic Sino-Tibetan languages lack any shared innovations in phonology or morphology to show that they comprise a clade of the phylogenetic tree. History During the 18th century, several scholars noticed parallel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-European
The Indo-European languages are a language family native to the northern Indian subcontinent, most of Europe, and the Iranian plateau with additional native branches found in regions such as Sri Lanka, the Maldives, parts of Central Asia (e.g., Tajikistan and Afghanistan), Armenia, and areas of southern India. Historically, Indo-European languages were also spoken in Anatolia. Some European languages of this family—English language, English, French language, French, Portuguese language, Portuguese, Russian language, Russian, Spanish language, Spanish, and Dutch language, Dutch—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, including Albanian language, Albanian, Armenian language, Armenian, Balto-Slavic, Celtic languages, Celtic, Germanic languages, Germanic, Hellenic languages, Hellenic, Indo-Iranian languages, Indo-Iranian, and Italic languages, ...

Caste
A caste is a Essentialism, fixed social group into which an individual is born within a particular system of social stratification: a caste system. Within such a system, individuals are expected to marry exclusively within the same caste (endogamy), follow lifestyles often linked to a particular occupation, hold a ritual status observed within a hierarchy, and interact with others based on cultural notions of social exclusion, exclusion, with certain castes considered as either more pure or more polluted than others. The term "caste" is also applied to morphological groupings in eusocial insects such as ants, bees, and termites#caste, termites. The paradigmatic ethnographic example of caste is the division of India's Hinduism, Hindu society into rigid social groups. Its roots lie in South Asia's ancient history and it still exists; however, the economic significance of the caste system in India seems to be declining as a result of urbanisation and affirmative action programs. ...
