Genetic Studies On Jews
Genetic studies on Jews are part of the population genetics discipline and are used to analyze the chronology of Jewish migration accompanied by research in other fields, such as history, linguistics, archaeology, and paleontology. These studies investigate the origins of various Jewish ethnic divisions. In particular, they examine whether there is a common genetic heritage among them. Studies of autosomal DNA, which look at the entire DNA mixture, show that Jewish populations have tended to form relatively closely related groups in independent communities with most in a community sharing significant ancestry. For populations of the Jewish diaspora, the genetic composition of Ashkenazi, Sephardi, and Mizrahi Jewish populations show significant amounts of shared Middle Eastern ancestry. According to geneticist Doron Behar and colleagues (2010), this is "consistent with a historical formulation of the Jewish people as descending from ancient Hebrew and Israelites of the ...

Population Genetics
Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure. Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis. Its primary founders were Sewall Wright, J. B. S. Haldane and Ronald Fisher, who also laid the foundations for the related discipline of quantitative genetics. Traditionally a highly mathematical discipline, modern population genetics encompasses theoretical, laboratory, and field work. Population genetic models are used both for statistical inference from DNA sequence data and for proof/disproof of concept. What sets population genetics apart from newer, more phenotypic approaches to modelling evolution, such as evolutionary game theory and adaptive dynamics, is its emphasis on such genetic phenomena as dominance, ...

Maghrebi Jews
:''See Mashriqi Jews for more information about Jews in the rest of North Africa and Western Asia.'' Maghrebi Jews ( or , ''Maghrebim'') or North African Jews ( ''Yehudei Tzfon Africa'') are ethnic Jews who had traditionally lived in the Maghreb region of North Africa (''al-Maghrib'', Arabic for "the west") under Arab rule during the Middle Ages. Established Jewish communities had existed in North Africa long before the arrival of Sephardi Jews, expelled from Portugal and Spain. Due to proximity, the term 'Maghrebi Jews' (Moroccan Jews, Algerian Jews, Tunisian Jews, and Libyan Jews) sometimes refers to Egyptian Jews as well, even though there are important cultural differences between the history of Egyptian and Maghrebi Jews. These Jews originating from North Africa constitute the second largest Jewish diaspora group. Maghrebi Jews lived in multiple communities in North Africa for over 2,000 years, with the oldest Jewish communities present during Roman times and possibly as e ...

Nicholas Wade
Nicholas Michael Landon Wade (born 17 May 1942) is a British author and journalist. He is the author of numerous books, and has served as staff writer and editor for ''Nature'', ''Science'', and the science section of ''The New York Times''. His 2014 book '' A Troublesome Inheritance: Genes, Race and Human History'' was widely denounced by the scientific community for misrepresenting research into human population genetics. In May 2021, Wade published an article in support of the COVID-19 lab leak hypothesis, fueling the controversy around the origins of the virus. Wade's claims about the origin of COVID-19 are at odds with the prevailing view among scientists. Early life and education Wade was born in Aylesbury, England and educated at Eton College. He is a grandson of Lawrence Beesley, a survivor of the sinking of the ''Titanic''. He earned a Bachelor of Arts degree in Natural Sciences from King's College, Cambridge in 1964, and immigrated to the United States in 1970. ...

Khazar Hypothesis Of Ashkenazi Ancestry
The Khazar hypothesis of Ashkenazi ancestry, often called the Khazar myth by its critics, is a largely abandoned historical hypothesis. The hypothesis postulated that Ashkenazi Jews were primarily, or to a large extent, descended from Khazars, a multi-ethnic conglomerate of mostly Turkic peoples who formed a semi-nomadic khanate in and around the northern and central Caucasus and the Pontic–Caspian steppe. The hypothesis also postulated that after collapse of the Khazar empire, the Khazars fled to Eastern Europe and made up a large part of the Jews there. The hypothesis draws on some medieval sources such as the Khazar Correspondence, according to which at some point in the 8th–9th centuries, a small number of Khazars were said by Judah Halevi and Abraham ibn Daud to have converted to Rabbinic Judaism. The scope of the conversion within the Khazar Khanate remains uncertain, but the evidence used to tie the Ashkenazi communities to the Khazars is meager and subject to conflic ...

Most of the Beta Israel community immigrated to Israel in the late 20th century. The Beta Israel lived in northern and northwestern Ethiopia, in more than 500 small villages which were spread over a wide territory, alongside populations that were Muslim and predominantly Christian. Most of them were concentrated mainly on what are today North Gondar Zone, Shire Inda Selassie, Wolqayit, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cochin Jews
Cochin Jews (also known as Malabar Jews or Kochinim, from ) are the oldest group of Jews in India, with roots that are claimed to date back to the time of King Solomon. The Cochin Jews settled in the Kingdom of Cochin in South India, now part of the state of Kerala. As early as the 12th century, mention is made of the Jews in southern India by Benjamin of Tudela. They are known to have developed Judeo-Malayalam, a dialect of Malayalam language. Following their expulsion from Iberia in 1492 by the Alhambra Decree, a few families of Sephardi Jews eventually made their way to Cochin in the 16th century. They became known as Paradesi Jews (or Foreign Jews). The European Jews maintained some trade connections to Europe, and their language skills were useful. Although the Sephardim spoke Ladino (i.e. Spanish or Judeo-Spanish), in India they learned Judeo-Malayalam from the Malabar Jews.Katz 2000; Koder 1973; Thomas Puthiakunnel 1973.

Bene Israel
The Bene Israel (), also referred to as the "Shanivar Teli" () or " Native Jew" caste, are a community of Jews in India. It has been suggested that they are the descendants of one of the Ten Lost Tribes via their ancestors who had settled there centuries ago. In the 19th century, after they were taught about normative (Ashkenazi and Sephardi) Judaism, they migrated from villages in the Konkan region to nearby cities throughout British India—primarily to Mumbai, but also to Pune, Ahmedabad, and Karachi (now in Pakistan), where they gained prominent positions within the British colonial government and the Indian Army. In the early part of the 20th century, many Bene Israel became active in the Indian film industry as actresses/actors, producers, and directors. With Indian independence in 1947 followed by the Israeli Declaration of Independence in 1948, many Bene Israel, including those who had arrived in India after their exodus from newly-independent Pakistan, soon immigrated ...

Southern Europe
Southern Europe is the southern region of Europe. It is also known as Mediterranean Europe, as its geography is essentially marked by the Mediterranean Sea. Definitions of Southern Europe include some or all of these countries and regions: Albania, Andorra, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, East Thrace, Gibraltar, Greece, Italy, Kosovo, Malta, Moldova, Monaco, Montenegro, North Macedonia, Portugal, Romania, San Marino, Serbia, Slovenia, Southern France, Spain, and Vatican City (the Holy See). Southern Europe is focused on the three peninsulas located in the extreme south of the European continent. These are the Iberian Peninsula, the Apennine Peninsula, and the Balkan Peninsula. These three peninsulas are separated from the rest of Europe by towering mountain ranges, respectively by the Pyrenees, the Alps and the Balkan Mountains. The location of these peninsulas in the heart of the Mediterranean Sea, as well as their mountainous reliefs, provide them ...

Genetic Admixture
Genetic admixture occurs when previously diverged or isolated genetic lineages mix.⅝ Admixture results in the introduction of new genetic lineages into a population. Examples Climatic cycles facilitate genetic admixture in cold periods and genetic diversification in warm periods. Natural flooding can cause genetic admixture within populations of migrating fish species. Genetic admixture may have an important role for the success of populations that colonise a new area and interbreed with individuals of native populations. Mapping Admixture mapping is a method of gene mapping that uses a population of mixed ancestry (an admixed population) to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best applied to populations with recent admixture from two populations that were previously genetically isolated. The method attempts to correlate the degree of ancestry near a genetic locus w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
