Jin (Chinese Surname)
Jin is the Hanyu pinyin transliteration of a number of Chinese surnames. The most common one, Jīn , literally means "gold" and is 29th in the list of "Hundred Family Surnames". As of 2006, it is ranked the List of common Chinese surnames, 64th most common Chinese surname and is sometimes transliterated as Chin. The other, less common, surnames that are "Jin" in pinyin include Jìn (/) and Jìn (). 金 (Jīn) Mythology Jin is an ancient surname, dating back over 4,000 years. It was first mentioned during the period ruled by the Yellow Emperor, a legendary Chinese sovereign and cultural hero, who is considered in Chinese mythology to be the ancestor of all Han Chinese. The legend behind the Jin surname is as follows: The Yellow Emperor's son, Yi Zhi (Shaohao), eventually succeeded him. On the same day he was installed as leader, a golden Phoenix (mythology), phoenix flew down and perched on top of a house exactly opposite of where he sat. His followers reckoned it was an auspi ...

Northern And Southern China
Northern China () and Southern China () are two approximate regions within China. The exact boundary between these two regions is not precisely defined and only serve to depict where there appears to be regional differences between the climates and localities of northern regions of China vs southern regions of China. Nevertheless, regional differences in culture and language have historically fostered a number of local identities. Extent Often used as the geographical dividing line between northern and southern China is the Qinling–Huaihe Line (lit. Qin Mountains–Huai River Line). This line approximates the 0 °C January isotherm and the isohyet in China. Culturally, however, the division is more ambiguous. In the eastern provinces like Jiangsu and Anhui, the Yangtze River may instead be perceived as the north–south boundary instead of the Huai River, but this is a recent development. There is an ambiguous area, the region around Nanyang, Henan, that lies in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnic Groups Of Africa
The ethnic groups of Africa number in the thousands, with each population generally having its own language (or dialect of a language) and culture. The ethnolinguistic groups include various Afroasiatic, Khoisan, Niger-Congo, and Nilo-Saharan populations. The official population count of the various ethnic groups in Africa is highly uncertain, both due to limited infrastructure to perform censuses and due to the rapid population growth. There have also been accusations of deliberate misreporting in order to give selected ethnicities numerical superiority (as in the case of Nigeria's Hausa, Fulani, Yoruba, and Igbo peoples). A 2009 genetic clustering study, which genotyped 1327 polymorphic markers in various African populations, identified six ancestral clusters. The clustering corresponded closely with ethnicity, culture and language. A 2018 whole genome sequencing study of the world's populations observed similar clusters among the populations in Africa. At K=9, distinct ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeast Asian
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of 26 atolls of Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is completely in the Northern Hemisphere. East Timor and the southern portion of Indonesia are the only parts that are south of the Equator. The region lies near the intersection of geological plates, with both heavy seismic and volc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

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] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Gene Pool
The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Description A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection. Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small. When all individuals in a population are identical with regard to a particular phenotypic trait, the population is said to be 'monomorphic'. When the individuals show several variants of a particular trait they are said to be polymorphic. History The Russian geneticist Alexander Sergeevich Serebrovsky first formulated the concept in the 1920s as ''genofond'' (gene fund), a w ...

Recent African Origin Of Modern Humans
In paleoanthropology, the recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is the dominant model of the geographic origin and early migration of anatomically modern humans (''Homo sapiens''). It follows the early expansions of hominins out of Africa, accomplished by ''Homo erectus'' and then ''Homo neanderthalensis''. The model proposes a "single origin" of ''Homo sapiens'' in the taxonomic sense, precluding parallel evolution in other regions of traits considered anatomically modern, but not precluding multiple admixture between ''H. sapiens'' and archaic humans in Europe and Asia. ''H. sapiens'' most likely developed in the Horn of Africa between 300,000 and 200,000 years ago, although an alternative hypothesis argues that diverse morphological features of ''H. sapiens'' appeared locally in different parts of Africa and converged due t ...

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 ...
