Haplogroup P (Y-DNA)
Haplogroup P also known as P-F5850 or K2b2 is a Y-chromosome DNA haplogroup in human genetics. P-F5850 is a branch of K2b (previously Haplogroup MPS; P331), which is a branch of Haplogroup K2 (K-M526). The haplogroup K2b splits into K2b1 (haplogroup MS*) and K2b2 (haplogroup P-F580, Y-DNA P*). Basal P* (P-PF5850*) is found in Southeast Asia. The primary branches (clades) of P-F580 are P-P295 (P1a, formerly P*) which is found among South and Southeast Asians as well as Oceanians, P-FT292000 (P1b, formerly P3) with unknown distribution, and P-M45 (P1c, formerly P1) commonly found among Siberians and Central Asians. P-M45 (P1c) is, in turn, the parent node of Haplogroup Q (Q-M242) and Haplogroup R (R-M207). The major subclades of Haplogroups P-M45, Q and R now include most males among Europeans, Native Americans, South Asians, North Africans, and Central Asians. Origin and dispersal Karafet et al. 2015 suggests an origin and dispersal of haplogroup P and its ancestr ... [...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] |
Human Y-chromosomal Phylogeny And Haplogroup Distribution
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of s ...

Aeta People
Aeta (Ayta ), Agta and Dumagat, are collective terms for several indigenous peoples who live in various parts of Luzon islands in the Philippines. They are included in the wider Negrito grouping of the Philippines and the rest of Southeast Asia, with whom they share superficial common physical characteristics such as: dark skin tones; short statures; frizzy to curly hair; and a higher frequency of naturally lighter hair colour ( blondism) relative to the general population. They are thought to be among the earliest inhabitants of the Philippines—preceding the Austronesian migrations. Regardless, the modern Aeta populations have significant Austronesian admixture, and speak Austronesian languages. Aeta communities were historically nomadic hunter-gatherers, typically consisting of approximately one to five families per mobile group. Groups under the "Aeta" umbrella term are normally referred to after their geographic locations or their common languages. Etymology The e ...

Island South East 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 ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subclade
In genetics, a subclade is a subgroup of a haplogroup. Naming convention Although human mitochondrial DNA (mtDNA) and Y chromosome DNA (Y-DNA) haplogroups and subclades are named in a similar manner, their names belong to completely separate systems. mtDNA mtDNA haplogroups are defined by the presence of a series of single-nucleotide polymorphism (SNP) markers in the hypervariable regions and the coding region of mitochondrial DNA. They are named with the capital letters A through Z, with further subclades named using numbers and lower case letters. Y-DNA Y-DNA haplogroups are defined by the presence of a series of SNP markers on the Y chromosome. Subclades are defined by a ''terminal SNP'', the SNP furthest down in the Y chromosome phylogenetic tree. Human Y-DNA The Y Chromosome Consortium (YCC) developed a system of naming major human Y-DNA haplogroups with the capital letters A through T, with further subclades named using numbers and lower case letters (YCC longhand nom ...

Tianyuan Man
Tianyuan man ( zh, t=田園洞人, s=田园洞人, p=Tiányuándòng Rén) are the remains of one of the earliest modern humans to inhabit East Asia. In 2007, researchers found 34 bone fragments belonging to a single individual at the Tianyuan Cave near Beijing, China. Radiocarbon dating shows the bones to be between 42,000 and 39,000 years old, which may be slightly younger than the only other finds of bones of a similar age at the Niah Caves in Sarawak on the South-east Asian island of Borneo. Subsistence Nothing is known directly about the material culture of this individual, since so far no artifacts or other cultural remains have been found at the site. Isotope analysis suggests that a substantial part of his diet came from freshwater fish. Physical anthropology Morphology Tianyuan man is considered an early modern homo sapiens. He lacks several mandibular features common among western Eurasian late archaic humans, showing its divergence. Based on the rate of dental occlu ...

Malay Peninsula
The Malay Peninsula is located in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung District, Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The Titiwangsa Mountains are part of the Tenasserim Hills system and form the backbone of the peninsula and the southernmost section of the central cordillera, which runs from Tibet through the Kra Isthmus, the peninsula's narrowest point, into the Malay Peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra, and the south coast is separated from the island of Singapore by the Straits of Johor. Etymology The Malay term ''Tanah Melayu'' is derived from the word ''Tanah'' (land) and ''Melayu'' (Malays (ethnic group), Malays), thus ...
