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 history. The geographic position of South Asia 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 sub–populations have shown that most of the ancestral nodes of the phylogenetic tree of all the mtDNA types originated in South Asia. Conclusions of studies based on Y Chromosome variation and Autosomal DNA variation have been varied. South Asians are descendants of an indigenous South Asian component (termed ''Ancient Ancestral South Indians'', short "AASI"), closest to modern isolated tribal groups from South India, as well as Andamanese peoples, and more distantly related to Aboriginal Australians and East Asians and later-arriving West-Eurasian (European/Middle ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the con ...

Andamanese
The Andamanese are the indigenous peoples of the Andaman Islands, part of India's Andaman and Nicobar Islands union territory in the southeastern part of the Bay of Bengal in Southeast Asia. The Andamanese peoples are among the various groups considered Negrito, owing to their dark skin and diminutive stature. All Andamanese traditionally lived a hunter-gatherer lifestyle, and appear to have lived in substantial isolation for thousands of years. It is suggested that the Andamanese settled in the Andaman Islands around the latest glacial maximum, around 26,000 years ago. The Andamanese peoples included the Great Andamanese and Jarawas of the Great Andaman archipelago, the Jangil of Rutland Island, the Onge of Little Andaman, and the Sentinelese of North Sentinel Island. At the end of the 18th century, when they first came into sustained contact with outsiders, an estimated 7,000 Andamanese remained. In the next century, they experienced a massive population decline due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Gr ...

Fertile Crescent
The Fertile Crescent ( ar, الهلال الخصيب) is a crescent-shaped region in the Middle East, spanning modern-day Iraq, Syria, Lebanon, Israel, State of Palestine, Palestine and Jordan, together with the northern region of Kuwait, southeastern region of Turkey and the western portion of Iran. Some authors also include Cyprus and Northern Egypt. The Fertile Crescent is believed to be the very first region where Agriculture, settled farming emerged as people started the process of clearance and modification of natural vegetation to grow newly domesticated plants as crops. Early human civilizations such as Sumer in Mesopotamia flourished as a result. Technological advances in the region include the development of History of agriculture, agriculture and the use of Irrigation#History, irrigation, of History of writing#Bronze Age writing, writing, the Wheel#History, wheel, and History of glass, glass, most emerging first in Mesopotamia.

Tibeto-Burman
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 para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austroasiatic
The Austroasiatic languages , , are a large language family in Mainland Southeast Asia and South Asia. These languages are scattered throughout parts of Thailand, Laos, India, Myanmar, Malaysia, Bangladesh, Nepal, and southern China and are the majority languages of Vietnam and Cambodia. There are around 117 million speakers of Austroasiatic languages. Of these languages, only Vietnamese, Khmer, and Mon have a long-established recorded history. Only two have official status as modern national languages: Vietnamese in Vietnam and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand. In Myanmar, the Wa language is the de facto official language of Wa State. Santali is one of the 22 scheduled languages of India. The rest of the languages are spoken by minority groups and have no official status. '' Ethnologue'' identifies 168 Austroasiatic languages. These form thirteen established families (plus perhaps Shompen, which is poorly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic Period
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levant
The Levant () is an approximation, approximate historical geography, historical geographical term referring to a large area in the Eastern Mediterranean region of Western Asia. In its narrowest sense, which is in use today in archaeology and other cultural contexts, it is equivalent to a stretch of land bordering the Mediterranean in South-western Asia,Gasiorowski, Mark (2016). ''The Government and Politics of the Middle East and North Africa''. }, ), meaning "the eastern place, where the Sun rises". In the 13th and 14th centuries, the term ''levante'' was used for Italian maritime commerce in the Eastern Mediterranean, including Greece, Anatolia, Syria (region), Syria-Palestine, and Egypt, that is, the lands east of Republic of Venice, Venice. Eventually the term was restricted to the Muslim countries of Syria-Palestine and Egypt. In 1581, England set up the Levant Company to monopolize commerce with the Ottoman Empire. The name ''Levant States'' was used to refer to the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurignacian
The Aurignacian () is an archaeological industry of the Upper Paleolithic associated with European early modern humans (EEMH) lasting from 43,000 to 26,000 years ago. The Upper Paleolithic developed in Europe some time after the Levant, where the Emiran period and the Ahmarian period form the first periods of the Upper Paleolithic, corresponding to the first stages of the expansion of ''Homo sapiens'' out of Africa. They then migrated to Europe and created the first European culture of modern humans, the Aurignacian. An Early Aurignacian or Proto-Aurignacian stage is dated between about 43,000 and 37,000 years ago. The Aurignacian proper lasts from about 37,000 to 33,000 years ago. A Late Aurignacian phase transitional with the Gravettian dates to about 33,000 to 26,000 years ago. The type site is the Cave of Aurignac, Haute-Garonne, south-west France. The main preceding period is the Mousterian of the '' Neanderthals''. One of the oldest examples of figurative art, the V ...

Irula People
Irula, also known as Iruliga'','' are a Dravidian ethnic group inhabiting the Indian states of Tamil Nadu, Kerala and Karnataka. A scheduled tribe, their population in this region is estimated at around 200,000 people. People of Irula ethnicity are called ''Irular'', and speak Irula, which belongs to the Dravidian family. Etymology ''Irular'' means "dark people" in Tamil and Malayalam, from the root word ''irul'', meaning "darkness." Thurston speculated that it either referred to the darkness of the jungles which they inhabited or their dark skin complexion. Distribution The tribe numbers around 200,000 spread across three states: 189,621 in Tamil Nadu, 23,721 in Kerala and 10,259 in Karnataka. Those in Karnataka are named Iruligas. The Irulas are mainly concentrated in northern Tamil Nadu: in a wedge extending from Krishnagiri and Dharmapuri districts in the west to Ariyalur and Cuddalore districts in the south and Tiruvallur district in the north.

Indian Subcontinent
The Indian subcontinent is a physiographical region in Southern Asia. It is situated on the Indian Plate, projecting southwards into the Indian Ocean from the Himalayas. Geopolitically, it includes the countries of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka."Indian subcontinent". '' New Oxford Dictionary of English'' () New York: Oxford University Press, 2001; p. 929: "the part of Asia south of the Himalayas which forms a peninsula extending into the Indian Ocean, between the Arabian Sea and the Bay of Bengal. Historically forming the whole territory of Greater India, the region is now divided into three countries named Bangladesh, India and Pakistan." The terms ''Indian subcontinent'' and ''South Asia'' are often used interchangeably to denote the region, although the geopolitical term of South Asia frequently includes Afghanistan, which may otherwise be classified as Central Asian.John McLeod, The history of India', page 1, Greenwood Publishing ...
