Father Tongue Hypothesis
The Father Tongue hypothesis proposes that humans tend to speak their father's language. It is based on the discovery, in 1997, of a closer correlation between language and Y-chromosomal variation than between language and mitochondrial DNA variation. The initial work was performed on African and European samples by a team of population geneticists led by Laurent Excoffier. On the basis of these and similar findings by other geneticists, the hypothesis was elaborated by historical linguist George van Driem in 2010 that the teaching by a mother of her spouse's tongue to her children is a mechanism by which language has preferentially been spread over time. Focusing on prehistoric language shift in already settled areas, examples worldwide show that as little as 10–20% of prehistoric male immigration can (but need not) cause a language switch, indicating an elite imposition such as may have happened with the appearance of the first farmers or metalworkers in the Neolithic, Bronz ...

E1b1a
Haplogroup E-V38 is a human Y-chromosome DNA haplogroup. It is primarily distributed in Sub Saharan Africa. E-V38 has two basal branches, E-M329 (formerly E1b1c or E1b1*) and E-M2 (formerly E3a & E1b1a). The E-M329 subclade is today almost exclusively found in Ethiopia. E-M2 is the predominant subclade in Western Africa, Central Africa, Southern Africa and the region of African Great Lakes, and occurs at only moderate frequencies in some parts of North Africa, West Asia and Southern Europe. Origins The discovery of two SNPs (V38 and V100) by Trombetta et al. (2011) significantly redefined the E-V38 phylogenetic tree. This led the authors to suggest that E-V38 may have originated in East Africa. V38 joins the West African-affiliated E-M2 and the northern East African-affiliated E-M329 with an earlier common ancestor who, like E-P2, may have also originated in East Africa. The downstreams SNP E-M180 may have originated on the moist south-central Saharan savannah/grassland of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrilineality
Patrilineality, also known as the male line, the spear side or agnatic kinship, is a common kinship system in which an individual's family membership derives from and is recorded through their father's lineage. It generally involves the inheritance of property, rights, names, or titles by persons related through male kin. This is sometimes distinguished from cognate kinship, through the mother's lineage, also called the spindle side or the distaff side. A patriline ("father line") is a person's father, and additional ancestors, as traced only through males. Traditionally and historically people would identify the person's ethnicity with the father's heritage and ignore the maternal ancestry in the ethnic factor. In the Bible In the Bible, family and tribal membership appears to be transmitted through the father. For example, a person is considered to be a priest or Levite, if his father is a priest or Levite, and the members of all the Twelve Tribes are called Israelites because ...

Austroasiatic
The Austroasiatic languages , , are a large language family A language family is a group of languages related through descent from a common ''ancestral language'' or ''parental language'', called the proto-language of that family. The term "family" reflects the tree model of language origination in h ... 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 language, Vietnamese, Khmer language, Khmer, and Mon language, 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.

Elamo-Dravidian Languages
The Elamo-Dravidian language family is a hypothesised language family that links the Dravidian languages of Pakistan, and Southern India to the extinct Elamite language of ancient Elam (present-day southwestern Iran). Linguist David McAlpin has been a chief proponent of the Elamo-Dravidian hypothesis. The hypothesis has gained attention in academic circles, but has been subject to serious criticism by linguists, and remains only one of several scenarios for the origins of the Dravidian languages. Elamite is generally accepted by scholars to be a language isolate, unrelated to any other known language. History of the proposal The concept that Elamite and Dravidian are in some way related dates from the beginnings of both fields in the early nineteenth century. Edwin Norris was the first to publish an article in support of the hypothesis in 1853. Further evidence was proposed by Robert Caldwell when he published a comparative linguistics book in 1856 about the Dravidian languages. D ...

Haplogroup L-M20
Haplogroup L-M20 is a human Y-DNA haplogroup, which is defined by SNPs M11, M20, M61 and M185. As a secondary descendant of haplogroup K and a primary branch of haplogroup LT, haplogroup L currently has the alternative phylogenetic name of K1a, and is a sibling of haplogroup T (a.k.a. K1b). The presence of L-M20 has been observed at varying levels throughout South Asia, peaking in populations native to Balochistan (28%), and Southern India (19%), where as its peak level up to 68% is observed in Korova Tribes or Koraga people of coastal Karnataka and north Kerala. The clade also occurs in Afghanistan,Tajikistan and Anatolia, as well as at lower frequencies in Iran. It has also been present for millennia at very low levels in the Caucasus, Europe and Central Asia. The subclade L2 (L-L595) has been found in Europe and Western Asia, but is extremely rare. Phylogenetic tree There are several confirmed and proposed phylogenetic trees available for haplogroup L-M20. The scientifi ...

Haplogroup R-M207
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. According to geneticist Spencer Wells, haplogroup K, from which haplogroups P and Q descend, originated in the Middle East or Central Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan." However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they could ...

Kurgan Hypothesis
The Kurgan hypothesis (also known as the Kurgan theory, Kurgan model, or steppe theory) is the most widely accepted proposal to identify the Proto-Indo-European homeland from which the Indo-European languages spread out throughout Europe and parts of Asia. It postulates that the people of a Kurgan culture in the Pontic steppe north of the Black Sea were the most likely speakers of the Proto-Indo-European language (PIE). The term is derived from the Russian ''kurgan'' (), meaning tumulus or burial mound. The steppe theory was first formulated by Otto Schrader (1883) and V. Gordon Childe (1926), then systematized in the 1950s by Marija Gimbutas, who used the term to group various prehistoric cultures, including the Yamnaya (or Pit Grave) culture and its predecessors. In the 2000s, David Anthony instead used the core Yamnaya culture and its relationship with other cultures as a point of reference. Gimbutas defined the Kurgan culture as composed of four successive periods, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontic–Caspian Steppe
The Pontic–Caspian steppe, formed by the Caspian steppe and the Pontic steppe, is the steppeland stretching from the northern shores of the Black Sea (the Pontus Euxinus of antiquity) to the northern area around the Caspian Sea. It extends from Dobruja in the northeastern corner of Bulgaria and southeastern Romania, through Moldova and southern and eastern Ukraine, across the Russian Northern Caucasus, the Southern and lower Volga regions to western Kazakhstan, adjacent to the Kazakh steppe to the east, both forming part of the larger Eurasian Steppe. It forms a part of the Palearctic realm and of the temperate grasslands, savannas, and shrublands biome. The area corresponds to Cimmeria, Scythia, and Sarmatia of classical antiquity. Across several millennia, numerous tribes of nomadic horsemen used the steppe; many of them went on to conquer lands in the settled regions of Europe, Western Asia, and Southern Asia. The term Ponto-Caspian region is used in biogeography ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proto-Indo-Europeans
The Proto-Indo-Europeans are a hypothetical prehistoric population of Eurasia who spoke Proto-Indo-European (PIE), the ancestor of the Indo-European languages according to linguistic reconstruction. Knowledge of them comes chiefly from that linguistic reconstruction, along with material evidence from archaeology and archaeogenetics. The Proto-Indo-Europeans likely lived during the late Neolithic, or roughly the 4th millennium BC. Mainstream scholarship places them in the Pontic–Caspian steppe zone in Eurasia (present-day Ukraine and southern Russia). Some archaeologists would extend the time depth of PIE to the middle Neolithic (5500 to 4500 BC) or even the early Neolithic (7500 to 5500 BC) and suggest alternative location hypotheses. By the early second millennium BC, descendants of the Proto-Indo-Europeans had reached far and wide across Eurasia, including Anatolia (Hittites), the Aegean (the linguistic ancestors of Mycenaean Greece), the north of Europe (Corded War ...

Haplogroup O-M122
Haplogroup O-M122 (also known as Haplogroup O2 (formerly Haplogroup O3)) is an Eastern Eurasian Y-chromosome haplogroup. The lineage ranges across Southeast Asia and East Asia, where it dominates the paternal lineages with extremely high frequencies. It is also significantly present in Central Asia, especially among the Naimans, Naiman tribe of Kazakhs. This lineage is a descendant haplogroup of haplogroup O-M175 (Y-DNA), haplogroup O-M175. Origins Researchers believe that O-M122 first appeared in Southeast Asia approximately 25,000-30,000 years ago or roughly between 30,000 and 35,000 years ago according to more recent studies (Karmin ''et al.'' 2015, Poznik ''et al.'' 2016, YFull January 4, 2018). In a systematic sampling and genetic screening of an East Asian–specific Y-chromosome haplogroup (O-M122) in 2,332 individuals from diverse East Asian populations, results indicate that the O-M122 lineage is dominant in East Asian populations, with an average frequency of 44.3%. ...

Sino-Tibetan Languages
Sino-Tibetan, also cited as Trans-Himalayan in a few sources, is a family of more than 400 languages, second only to Indo-European in number of native speakers. The vast majority of these are the 1.3 billion native speakers of Chinese languages. Other Sino-Tibetan languages with large numbers of speakers include Burmese (33 million) and the Tibetic languages (6 million). Other languages of the family are spoken in the Himalayas, the Southeast Asian Massif, and the eastern edge of the Tibetan Plateau. Most of these have small speech communities in remote mountain areas, and as such are poorly documented. Several low-level subgroups have been securely reconstructed, but reconstruction of a proto-language for the family as a whole is still at an early stage, so the higher-level structure of Sino-Tibetan remains unclear. Although the family is traditionally presented as divided into Sinitic (i.e. Chinese) and Tibeto-Burman branches, a common origin of the non-Sinitic languages has n ...

Haplogroup N-M231
Haplogroup N (M231) is a Y-chromosome DNA haplogroup defined by the presence of the single-nucleotide polymorphism (SNP) marker M231. It is most commonly found in males originating from northern Eurasia. It also has been observed at lower frequencies in populations native to other regions, including parts of the Balkans, Central Asia, East Asia, and Southeast Asia. Origins Haplogroup NO-M214 – its most recent common ancestor with its sibling, haplogroup O-M175 – is estimated to have existed about 36,800–44,700 years ago.YFull Haplogroup YTree v6.05.11 at 25 September 2018.
