Genetic History Of The Middle East
The genetic history of the Middle East is the subject of research within the fields of human population genomics, archaeogenetics and Middle Eastern studies. Researchers use Y-DNA, mtDNA, and other autosomal DNAs to identify the genetic history of ancient and modern populations of Egypt, Persia, Mesopotamia, Anatolia, Arabia, the Levant, and other areas. History Developments in DNA sequencing in the 1970s and 1980s provided researchers with the tools needed to study human genetic variation and the genetics of human populations to discover founder populations of modern people groups and human migrations. In 2005, National Geographic launched The Genographic Project, led by 12 prominent scientists and researchers, to study and map historical human migration patterns by collecting and analyzing DNA samples from hundreds of thousands of people from around the world. Egypt Various DNA studies have found that the genetic variant frequencies of North African populations are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Genographic Project
The Genographic Project, launched on 13 April 2005 by the National Geographic Society and IBM, was a genetic anthropological study (sales discontinued on 31 May 2019) that aimed to map historical human migrations patterns by collecting and analyzing DNA samples. The final phase of the project was Geno 2.0 Next Generation. Upon retirement of the site, 1,006,542 participants in over 140 countries had joined the project. Project history Beginnings Created and led by project director Spencer Wells in 2005, The Genographic Project was a privately funded, not-for-profit collaboration between the National Geographic Society, IBM and the Waitt Foundation. Field researchers at eleven regional centers around the world began by collecting DNA samples from indigenous populations. Since the fall of 2015, the Project was led by Miguel Vilar. In fall 2012, the Genographic Project announced the completion of a new genotyping array, dedicated to genetic anthropology, called GenoChi ...

Y Chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers male development. The DNA in the human Y chromosome is composed of about 59 million base pairs, making it similar in size to chromosome 19. The Y chromosome is passed only from father to son. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest-evolving parts of the human genome. The human Y chromosome carries an estimated 100–200 genes, with between 45 and 73 of these being protein-coding. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome. ...

Haplogroup R (Y-DNA)
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 ...

Haplogroup T (Y-DNA)
Haplogroup T-M184, also known as Haplogroup T, is a human Y-chromosome DNA haplogroup. The unique-event polymorphism that defines this clade is the single-nucleotide polymorphism known as ''M184''. Other SNPs – ''M272'', ''PAGES129'', ''L810'', ''L455'', ''L452'', and ''L445'' – are considered to be phylogenetically equivalent to ''M184''. As a primary branch of haplogroup LT (a.k.a. K1), the basal, undivergent haplogroup T* currently has the alternate phylogenetic name of K1b and is a sibling of haplogroup L* (a.k.a. K1a). (Before 2008, haplogroup T and its subclades were known as haplogroup K2. The name K2 has since been reassigned to a primary subclade of haplogroup K.) It has two primary branches: T1 (T-L206) and T2 (T-PH110). T-M184 is unusual in that it is both geographically widespread and relatively rare. T1 (T-L206) – the numerically dominant primary branch of T-M184 – appears to have originated in Western Asia, and possibly spread from there into the East A ...

Haplogroup G (Y-DNA)
Haplogroup G (M201) is a human Y-chromosome haplogroup. It is one of two branches of the parent haplogroup GHIJK, the other being Haplogroup HIJK, HIJK. G-M201 is most commonly found among various ethnic groups of the Caucasus, but is also widely distributed at low frequencies among ethnic groups throughout Europe, South Asia, Central Asia, and North Africa. The most commonly occurring subclades are G1* (M285) and many subclades of G2 (G-P287), especially: G2a (P15), Haplogroup G-FGC7535, G2a1 (G-FGC7535, formerly G-L293), Haplogroup G-P303, G2a2b2a (G-P303) formerly G2a3b1); Haplogroup G-M406, G2a2b1 (G-M406) formerly G2a3a; G2a2b2a1 (G-L140) formerly G2a3b1a; G2a2b2a1a1b (G-L497) formerly G2a3b1a2; G2a2b2a1a1a1 (G-L13) formerly G2a3b1a1a; G2a2b2a1a1c1a (G-CTS5990 or G-Z1903) formerly G2a3b1a3; G2b (G-M3115) and; Haplogroup G-M377, G2b1 (G-M377), formerly G2b. Origins Various estimated dates and locations have been proposed for the origin of G-M201, most of them in Western Asi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup J (Y-DNA)
Haplogroup J-M304, also known as J,ISOGGbr> ''Y-DNA Haplogroup J and its Subclades - 2016'' (2 February 2016). is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, the Caucasus, Europe, Western Asia, Central Asia, South Asia, and Southeast Asia. Haplogroup J-M304 is divided into two main subclades (branches), J-M267 and J-M172. Origins Haplogroup J-M304 is believed to have split from the haplogroup I-M170 roughly 43,000 years ago in Western Asia, as both lineages are haplogroup IJ subclades. Haplogroup IJ and haplogroup K derive from haplogroup IJK, and only at this level of classification does haplogroup IJK join with Haplogroup G-M201 and Haplogroup H as immediate descendants of Haplogroup F-M89. J-M304 is defined by the M304 genetic marker, or the equivalent 12f2.1 marker. The main current subgroups J-M267 and J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup E1b1b1a (Y-DNA)
Haplogroup E-V68, also known as E1b1b1a, is a major human Y-chromosome DNA haplogroup found in North Africa, the Horn of Africa, Western Asia and Europe. It is a subclade of the larger and older haplogroup, known as E1b1b or E-M215 (also roughly equivalent to E-M35). The E1b1b1a lineage is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome, which is known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics. E-V68 is dominated by its longer-known subclade E-M78. In various publications, both E-V68 and E-M78 have been referred to by other names, especially phylogenetic nomenclature such as "E3b1a" which are designed to show their place on the family tree of all human males. These various names change as new discoveries are made and are discussed below. Origins E-M78, like its parent clade E-V68, is thought to have an African origin. Based on genetic STR var ...

Haplogroup E1b1b (Y-DNA)
E-M215, also known as E1b1b and formerly E3b, is a major human Y-chromosome DNA haplogroup. It is a division of the macro-haplogroup E-M96, which is defined by the single-nucleotide polymorphism (SNP) mutation M215. In other words, it is one of the major patrilineality, patrilineages of humanity, linking from father-to-son back to a common male-line ancestor ("Y-chromosomal Adam"). It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics. The E-M215 haplogroup has two ancient branches that contain all the known modern E-M215, E-M35 and E-M281 subclades. Of the latter two E-M215 subhaplogroups, the only branch that has been confirmed in a native population outside of Ethiopia is E-M35. E-M35 in turn has two known branches, Haplogroup E-V68, E-V68 and Haplogroup E-Z827, E-Z827, which contain by far the majority of all modern E-M215 subclade bearers. The E-V257 and E-V68 subclades each respectively their highest freque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Sub Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead grouped with the definition of MENA (i.e. Middle East–North Africa) as it is part of the ...
