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 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 flew down and perched on top of a house exactly opposite of where he sat. His followers reckoned it was an auspicious beginning. They decided to use gold as the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multiregional Origin Of Modern Humans
The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution. Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as '' H. erectus'' and Neanderthals as well as modern forms, and evolved worldwide to the diverse populations of anatomically modern humans (''Homo sapiens''). The hypothesis contends that the mechanism of clinal variation through a model of "Centre and Edge" allowed for the necessary balance between genetic drift, gene flow and selection throughout the Pleistocene, as well as overall evolution as a global species, but while retaining regional differences in certain morphological features. Proponents of mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve '' pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide sci ...

North China
North China, or Huabei () is a geographical region of China, consisting of the provinces of Beijing, Tianjin, Hebei, Shanxi and Inner Mongolia. Part of the larger region of Northern China (''Beifang''), it lies north of the Qinling–Huaihe Line, with its heartland in the North China Plain. In modern times, the area has shifted in terms of socio-political and economic composition. Nowadays unique, embracing a North Chinese culture, it is influenced by Marxism, Soviet systems of industry while preserving a traditional Chinese indigenous culture. Agriculturally, the region cultivates wheat. Most inhabitants here speak variants of Northern Chinese languages such as Mandarin, which includes Beijing dialect and its cousin variants. The Beijing dialect is largely the basis of Standard Chinese (or Standard Mandarin), the official language of the People's Republic of China (PRC). Jin Chinese and Mongolian are also widely spoken due to the political and cultural history of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yangtze River
The Yangtze or Yangzi ( or ; ) is the longest river in Asia, the third-longest in the world, and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains (Tibetan Plateau) and flows in a generally easterly direction to the East China Sea. It is the seventh-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population. The Yangtze has played a major role in the history, culture, and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking, and war. The prosperous Yangtze Delta generates as much as 20% of China's GDP. The Three Gorges Dam on the Yangtze is the largest hydro-electric power station in the world that is in use. In mid-2014, the Chinese government announced it was building a multi-tier transport netw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 li ... [...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 anc ... [...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 syn ...

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, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
