Haplogroup K2
Haplogroup K2, also known as K-M526 and formerly known as MNOPS, is a human Y-DNA haplogroup. Relative to its age, the internal structure of K2 is extremely complex, and subclades of it are carried by males native to regions including Australasia, Oceania, Southeast Asia, South Asia, East Asia, Central Asia, the Americas, Europe, and the Horn of Africa. Many of its branches are very common, the most numerically important being R in Europe and South Asia and O in East and Southeast Asia (as well as recent immigrants to other continents). Haplogroups N and Q, while they are less common overall, are also very widespread, in northern Eurasia and the Americas respectively. M and S are almost entirely restricted to Oceania and eastern Indonesia, where they occur at high frequency. Rare subclades outside of these major lineages are known mainly from Island Southeast Asia (including the Andaman Islands and the Philippines). Basal paragroup K2* has been identified among native ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. 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 shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#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 waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Upper Paleolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans. It is followed by the Mesolithic. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago. It has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which may have contributed to the Neanderthal extinction, extinction of th ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...

Andaman Islands
The Andaman Islands () are an archipelago, made up of 200 islands, in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. The Andaman Islands are home to the Andamanese peoples, Andamanese, a group of indigenous people made up of a number of tribes, including the Jarawas (Andaman Islands), Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had Uncontacted peoples, little contact with any other people. The Indian government and coast guard protect th ...

Island Southeast Asia
Maritime Southeast Asia comprises the Southeast Asian countries of Brunei, Indonesia, Malaysia, the Philippines, Singapore, and East Timor. The terms Island Southeast Asia and Insular Southeast Asia are sometimes given the same meaning as Maritime Southeast Asia. Other definitions restrict Island Southeast Asia to just the islands between mainland Southeast Asia and the continental shelf of Australia and New Guinea. There is some variability as to whether Taiwan is included in this. Peter Bellwood includes Taiwan in his definition, as did Robert Blust, whilst there are examples that do not. The 16th-century term "East Indies" and the later 19th-century term "Malay Archipelago" are also used to refer to Maritime Southeast Asia. In Indonesia, the Old Javanese term " Nusantara" is also used as a synonym for Maritime Southeast Asia. The term, however, is nationalistic and has shifting boundaries. It usually only encompasses Peninsular Malaysia, the Sunda Islands, Maluku, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haplogroup S (Y-DNA)
Haplogroup S also known as S-B254 is a human human Y-chromosome DNA haplogroup, Y-DNA haplogroup, defined by the Single-nucleotide polymorphism, SNPs B254 and Z33355.International Society of Genetic Genealogy (ISOGG; 2017), ''Y-DNA Haplogroup Tree 2015'' (24 March 2017). Until 2016, it was known as Haplogroup S1. S-M254 is the most common haplogroup among males in the New Guinea Highlands, Papua New Guinea Highlands. It is also relatively common in some parts of Oceania, Wallacea and among indigenous Australians. In a major correction to the phylogenetic tree during 2016, Haplogroup S-M230 was "demoted" from the position of basal (phylogenetics), basal clade S*, becoming S1a1b, while S-B254 was "promoted" in its place to the level of S*. It has two primary sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup M (Y-DNA)
Haplogroup M, AKA M-P256 and Haplogroup K2b1b (previously K2b1d) is a Human Y-chromosome DNA haplogroup, Y-chromosome DNA haplogroup. M-P256 is a descendant haplogroup of Haplogroup K2b1 (Y-DNA), Haplogroup K2b1, and is believed to have first appeared between 32,000 and 47,000 years ago. M-P256 is the most frequently occurring Y-chromosome haplogroup in West Papua (region), West Papua and western Papua New Guinea. In addition, M-P256 is also found in neighboring parts of Melanesia, Indonesia and indigenous Australians.

Haplogroup Q (Y-DNA)
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has two primary subclades: Q1/Q-L472 (also known as Q-MEH2) and Q2/Q-L275). These include numerous subclades that have been sampled and identified in males among modern populations. Q is the predominant Y-DNA haplogroup among Native Americans, Swati tribe and several peoples of Central Asia and Northern Siberia. Defining mutations The polymorphism M242, is a C→T transition residing in intron 1 (IVS-866) of the DBY gene and was discovered by Mark Seielstad et al. in 2003. The technical details of M242 are: :Nucleotide change: C to T :Position (base pair): 180 :Total size (base pairs): 366 :Forward 5′→ 3′: :Reverse 5′→ 3′: Other defining SNPs unique to Q-M242 include: FGC1752, F2603/M1020, L232/S432, M1115, Y2000/FGC1757, FGC6793, Y1984/FGC1753, Y1987/FGC1754/F6492, FGC7650(H), E337/L808/CTS3727/M1105, M1047(H), M1074, M1154, M1166, Y1972/FGC4603/F7839(H), Y2002/FGC1756/F6477(H), CTS7532/M1133, F30 ...

Haplogroup N (Y-DNA)
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. However, the basal paragroup N* has only been found in populations indigenous to China and Cambodia. Subclades of N-M231 have been found at low levels in Southeast Asia, the Pacific Islands, Southwest Asia and the Balkans. These factors tend to suggest that it originated in East Asia or 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 ...
