Haplogroup CT
Haplogroup CT is a human Y chromosome haplogroup, defining one of the major paternal lineages of humanity. Men who carry the CT clade have Y chromosomes with the SNP mutation M168, along with P9.1 and M294. These mutations are present in all modern human male lineages except A and B-M60, which are both found almost exclusively in Africa. The most recent common male line ancestor (TMRCA) of all CT men today probably predated the recent African origin of modern humans, a migration in which some of his descendants participated. He is therefore thought to have lived in Africa before this proposed migration. In keeping with the concept of " Y-chromosomal Adam" given to the patrilineal ancestor of all living humans, CT-M168 has therefore also been referred to in popularized accounts as being the lineage of "Eurasian Adam" or "Out of Africa Adam"; because, along with many African Y-lineages, all non-African Y-lineages descend from it.

Human Y Chromosome Haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs). The human Y-chromosome accumulates roughly two mutations per generation. "one mutation in every 30 million base pairs" Y-DNA haplogroups represent major branches of the Y-chromosome phylogenetic tree that share hundreds or even thousands of mutations unique to each haplogroup. The Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa. By examining other bottlenecks most Eurasian men (men from populations outsi ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup E-M96
Haplogroup E-M96 is a human Y-chromosome DNA haplogroup. It is one of the two main branches of the older and ancestral haplogroup DE, the other main branch being haplogroup D. The E-M96 clade is divided into two main subclades: the more common E-P147, and the less common E-M75. Origins Underhill (2001) proposed that haplogroup E may have arisen in East Africa. Some authors as Chandrasekar (2007), accept the earlier position of Hammer (1997) that Haplogroup E may have originated in West Asia, given that: * E is a clade of Haplogroup DE, with the other major clade, haplogroup D, being exclusively distributed in Asia. * DE is a clade within M168 with the other two major clades, C and F, considered to have already a Eurasian origin. However, several discoveries made since the Hammer articles are thought to make an Asian origin less likely: # Underhill and Kivisild (2007) demonstrated that C and F have a common ancestor meaning that DE has only one sibling which is non-African. ...

Western Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup C-V20
Haplogroup C-V20 (also known as Haplogroup C1a2) is a Y-chromosome haplogroup. It is one of two primary branches of Haplogroup C1a, one of the descendants of Haplogroup C1 (The other is C1a1 in Japan with an average amount of 5%). Haplogroup C-V20 is now distributed in Europe, North Africa, West Asia, and South Asia with very low frequency. History and Distribution Haplogroup C1a2 (V20) has been discovered in the remains of Palaeolithic people in Czech Republic (30,000 years ago), Belgium (35,000 years ago), and the Sunghir archaeological site near Vladimir, Russia. Regarding more recent prehistory, Haplogroup C-V20 has been found in the remains of a male (died ''ca.'' 7,000 years ago) associated with a late group of the Alföld Linear Pottery culture at Kompolt-Kigyósér, Hungary whose mtDNA belonged to haplogroup J1c1, the remains of a male (died ''ca.'' 7,000 years ago) associated with the LBK Culture at Apc-Berekalja (I.), Hungary whose mtDNA belonged to haplogroup K1 ...

Haplogroup C-M8
Haplogroup C-M8 also known as Haplogroup C1a1 is a Y-chromosome haplogroup. It is one of two branches of Haplogroup C1a, one of the descendants of Haplogroup C-M130. It has been found in about 6% (2.3% to 16.7%) of modern males sampled in Japan and has been considered to be a Y-DNA haplogroup descended from Jōmon people. Elsewhere, it has been observed among academic studies only in one individual in a sample collected on Jeju Island of South Korea and in commercial testing in one individual who has reported an origin in Liaoning province of China and one individual who has reported an origin in Seoul, South Korea. The MRCA with its sister haplogroup C-V20 dates back to 40,000Zhong H, Shi H, Qi XB et al. (July 2010).

Haplogroup C-F3393
Haplogroup C1 also known as C-F3393, is a major Y-chromosome haplogroup. It is one of two primary branches of the broader Haplogroup C, the other being C2 (also known as C-M217; the former Haplogroup C3). The basal paragroup, C1* (C-F3393*), has not been found in samples from living or dead males. Of the two primary branches, C1b is common in parts of Oceania and Asia. The other primary branch, C1a, is extremely rare worldwide and has been found mainly amongst individuals native to Japan or Europe and among Upper Paleolithic Europeans, with single cases known from Nepal and Jeju Island through academic studies and from an ethnic Armenian, an ethnic Kabyle, and an ethnic Han from Liaoning province of China through commercial testing. Distribution Subclades of C1 (C-F3393) are the predominant Y-DNA haplogroups among some Indigenous Australian peoples, some Pacific Islander peoples, and a few of the ethnic groups of the Lesser Sunda Islands of Indonesia. Other subclades are foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...
