Vedda People
The Vedda ( si, වැද්දා , ta, வேடர் (''Vēḍar'')), or Wanniyalaeto, are a minority indigenous group of people in Sri Lanka who, among other sub-communities such as Coast Veddas, Anuradhapura Veddas and Bintenne Veddas, are accorded indigenous status. The Vedda minority in Sri Lanka may become completely assimilated. Most speak Sinhala instead of their indigenous languages, which are nearing extinction. It has been hypothesized that the Vedda were probably the earliest inhabitants of Sri Lanka and have lived on the island since before the arrival of other ethnic groups in India. The Ratnapura District, which is part of the Sabaragamuwa Province, is known to have been inhabited by the Veddas in the distant past. This has been shown by scholars like Nandadeva Wijesekera. The very name ''Sabaragamuwa'' is believed to have meant the village of the ''Sabaras'' or "forest barbarians". Place-names such as ''Vedda-gala'' (Vedda Rock), ''Vedda-ela'' (Vedda Cana ...

Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Tamil People
The Tamil people, also known as Tamilar ( ta, தமிழர், Tamiḻar, translit-std=ISO, in the singular or ta, தமிழர்கள், Tamiḻarkaḷ, translit-std=ISO, label=none, in the plural), or simply Tamils (), are a Dravidian peoples, Dravidian ethno-linguistic group who trace their ancestry mainly to India’s South India, southern state of Tamil Nadu, union territory of Puducherry (union territory), Puducherry and to Sri Lanka. Tamils who speak the Tamil Language and are born in :Social groups of Tamil Nadu, Tamil clans are considered Tamilians. Tamils constitute 5.9% of the population in India (concentrated mainly in Tamil Nadu and Puducherry), 15% in Sri Lanka (excluding Sri Lankan Moors), 7% in Tamil Malaysians, Malaysia, 6% in Tamil Mauritians, Mauritius, and 5% in Indian Singaporeans, Singapore. From the 4th century BCE, urbanisation and mercantile activity along the western and eastern coasts of what is today Kerala and Tamil Nadu led to the develo ...

Haplogroup R (mtDNA)
Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa. Haplogroup R is a descendant of the macro- haplogroup N. Among the R clade's descendant haplogroups are B, U (and thus K), F, R0 (and thus HV, H, and V), and JT (the ancestral haplogroup of J and T). Origin Soares et al. (2009) estimate the age of haplogroup R at roughly 50,000 to 70,000 years ago. This is consistent with an emergence in the course of the Coastal Migration out of East Africa to West, South and Southeast Asia. It has been suggested that the early lineage of haplogroups M, N and R along the coastal route during the period of roughly 70,000 to 60,000 years ago. Haplogroup R has wide diversity and antiquity in the indigenous population of South Asia. Tribes and castes of Western and Southern I ...

Haplogroup U (mtDNA)
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic. Its various subclades (labelled U1–U9, diverging over the course of the Upper Paleolithic) are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands. Origins Haplogroup U descends from the haplogroup R mtDNA branch of the phylogenetic tree. The defining mutations (A11467G, A12308G, G12372A) are estimated to have arisen between 43,000 and 50,000 years ago, in the early Upper Paleolithic (around 46,530 ± 3,290 years before present, with a 95% confidence interval per Behar et al., 2012). Ancient DNA classified as belonging to the U* mitochondrial haplogroup has been recovered from human skeletal remains found in Western Siberia, which have been dated to c. 45,000 years ago.

Genetic Drift
Genetic drift, also known as allelic drift or the Wright effect, is the change in the frequency of an existing gene variant (allele) in a population due to random chance. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When few copies of an allele exist, the effect of genetic drift is more notable, and when many copies exist, the effect is less notable. In the middle of the 20th century, vigorous debates occurred over the relative importance of natural selection versus neutral processes, including genetic drift. Ronald Fisher, who explained natural selection using Mendelian genetics, held the view that genetic drift plays at most a minor role in evolution, and this remained the dominant view for several decades. In 1968, population geneticist Motoo Kimura rekindled the debate with his neutral theory of molecular evolution, which claims that ...

Australo-Melanesians
Australo-Melanesians (also known as Australasians or the Australomelanesoid, Australoid or Australioid race) is an outdated historical grouping of various people indigenous to Melanesia and Australia. Controversially, groups from Southeast Asia and South Asia were also sometimes included. While most authors included Papuans, Aboriginal Australians and Melanesians (mainly from Fiji, New Caledonia, Solomon Islands and Vanuatu), there was controversy about the inclusion of the various Southeast Asian populations grouped as "Negrito", or a number of dark-skinned tribal populations of the Indian subcontinent. The concept of dividing humankind into three, four or five races (often called Caucasoid, Mongoloid, Negroid, and Australoid) was introduced in the 18th century and further developed by Western scholars in the context of " racist ideologies" during the age of colonialism. With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 epid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Africa
North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in the west, to Egypt's Suez Canal. Varying sources limit it to the countries of Algeria, Libya, Morocco, and Tunisia, a region that was known by the French during colonial times as "''Afrique du Nord''" and is known by Arabs as the Maghreb ("West", ''The western part of Arab World''). The United Nations definition includes Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, and the Western Sahara, the territory disputed between Morocco and the Sahrawi Republic. The African Union definition includes the Western Sahara and Mauritania but not Sudan. When used in the term Middle East and North Africa (MENA), it often refers only to the countries of the Maghreb. North Africa includes the Spanish cities of Ceuta and Melilla, and plazas de s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...
