Dipteronia

Dipteronia

- Dipteronia sinensis

- Dipteronia dyeriana Dipteronia is a genus of two species in the soapberry family Sapindaceae, related to the maples and like them in the part of Sapindaceae formerly separated as Aceraceae. They are deciduous flowering shrubs or small trees, reaching 10-15 m tall. The leaf arrangement is opposite and pinnate. Inflorescence terminal or axillary, paniculate. Sepals 5. Petals 5. Staminate flowers: stamens 8. Bisexual flowers: ovary 2-celled. The fruit is a rounded samara containing two compressed nutlets, flat, encircled by a broad wing which turns from light green to red with ripening. There are only 2 species, Dipteronia sinensis and Dipteronia dyeriana; both are endemic to mainland China. Dipteronia dyeriana is listed by the [http://www.redlist.org/search/details.php?species=32340 IUCN] as being a "Red List" threatened species. The name Dipteronia stems from the Greek "di-" (two, both) & "pteron" (wings), from the winged fruits with wings on both sides of the seed. Category:Sapindales

Genus

In biology, a genus (plural genera) is a grouping in the classification of living organisms having one or more related and morphologically similar species. In the common binomial nomenclature, the name of an organism is composed of two parts: its genus (always capitalized) and a species modifier. An example is Homo sapiens, the name for the human species which belongs to the genus Homo. See scientific classification for more details of this system. The type genus of a taxon is usually the first genus to be named and described. Families, and in plants all taxa up to division, are named after the type genus. The genus and these higher taxa are typified by a specimen that shows the characteristics of the genus. The specimen used to describe this species is preserved as the holotype and designated as a generitype in a zoological museum or a herbarium to be available for further study. A generic name in one kingdom is allowed to bear the same name as a genus or other taxon name in another kingdom (though this is discouraged by the International Code of Zoological Nomenclature). For instance, Anura is a genus of plants in the family Asteraceae and the order of frogs; Aotus is the genus of golden peas and night monkeys; Oenanthe is the genus of wheatears and water dropworts, and Prunella is the genus of accentors and self-heal. It is, however, not allowed for two genera within the same kingdom to have the same name. This explains why the platypus genus is Ornithorhynchus — although the name Platypus was chosen by George Shaw in 1799, that name had already been given to the ambrosia beetle by Johann Friedrich Wilhelm Herbst in 1793. Since beetles and platypuses are both member of the kingdom Animalia, the name Platypus could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800.

- Acer saccharum - Sugar Maple Maples are trees or shrubs of the genus Acer. They are variously classified in a family of their own, the Aceraceae, or (together with the Hippocastanaceae) included in the Sapindaceae. This is a debate of very long standing, and Angiosperm Phylogeny Group favours a wide circumscription, as a matter of style. Angiosperm Phylogeny Group Maples are distinguished by opposite leaf arrangement. The leaves are usually palmately lobed, although palmate compound, pinnate compound, pinnate veined or unlobed shapes occur. The flowers are regular, pentamerous, and borne in racemes, corymbs, or umbels. Their distinctive fruits occur in pairs, called keys, shaped to spin as they fall and carry the seeds a considerable distance on the wind (see samara). The derivation of the name "acer" is uncertain, as it is a very old name. One of the options is that derives from the Latin acris (sharp), from the hardness of the wood, supposedly used for spears in the past. The leaves in most species are palmately veined and lobed, with 3-9 veins each leading to a lobe, one of which is in the middle. Several species, including the Paperbark Maple Acer griseum, Manchurian Maple Acer mandshuricum, Nikko Maple Acer maximowicziana, and Three-flower Maple Acer triflorum, have trifoliate leaves. The Manitoba Maple (Acer negundo) has pinnately compound leaves that may be simply trifoliate or may have 5, 7, or rarely 9 leaflets. One maple, the Hornbeam Maple Acer carpinifolium, has pinnately-veined simple leaves that resemble those of hornbeams. Maples flower in late winter or early spring, in most species with or just after the leaves appear, but in some before them. Their flowers are small and inconspicuous, though the effect of an entire avenue of maples in flower can be striking. They have five sepals, five petals about 1-6 mm long, 12 stamens about 6-10 mm long in two rings of six, and two pistils or a pistil with two styles. The ovary is superior and has two carpels, whose wings elongate the flowers, making it easy to tell which flowers are female. Within a few weeks to six months of flowering, the trees drop large numbers of seeds. Maples are important as cultivated ornamental plants, for syrup sources and timber production. Some species have bright autumnal leaf coloring. The Sugar Maple (Acer saccharum) is tapped for sap, which is then boiled to produce maple syrup or made into maple sugar or maple candy. Quebec is the world's largest producer of maple sugar products. The hard maple is the wood of choice for bowling pins and bowling alley lanes, and is yielded by Sugar Maple. Maples are an important early spring source of pollen and nectar for bees, especially honeybees, which use its resources for spring buildup. Maples are used as a food plant for the larvae of a number of Lepidoptera species (see List of Lepidoptera which feed on Maples). The flag of Canada depicts a stylized maple leaf and is a prominent national symbol. ;See also

Deciduous

Deciduous means "temporary" or "tending to fall off" (deriving from the Latin word decidere, to fall off).

Botany

In botany, deciduous plants, principally trees and shrubs, are those that lose all of their foliage for part of the year. In some cases, the foliage loss coincides with the incidence of winter in temperate or polar climates, while others lose their leaves during the dry season in climates with seasonal variation in rainfall. The converse of deciduous is evergreen. Many deciduous plants flower during the period when they are leafless, as this increases the effectiveness of pollination. The absence of leaves improves wind transmission of pollen in the case of wind-pollinated plants, and increases the visibility of the flowers to insects in insect-pollinated plants. This strategy is not without risks, as the flowers can be damaged by frost, or in dry season areas, result in water stress on the plant.

Anatomy

In anatomy, deciduous teeth, also called milk teeth, are those that fall out during the course of normal development. Other body parts that are shed, such as antlers, are also described as deciduous. Category:Botany Category:Mouth

Shrub

:"Shrub" is also a derogatory nickname for United States President George W Bush. George W Bush A shrub or bush is a horticultural rather than strictly botanical category of woody plant, distinguished from a tree by its multiple stems and lower height, usually less than 6 m tall. A large number of plants can be either shrubs or trees, depending on the growing conditions they experience. Small, low shrubs such as lavender, periwinkle and thyme are often termed subshrubs. A natural plant community dominated by shrubs is called a shrubland. The word bush can also refer to a type of plant community, as in the Australian bush. This is often characterised by scrubby, open woodland and is a generic term for Eucalyptus dominated woodland in particular. An area of cultivated shrubs in a park or garden is known as a shrubbery. When clipped as topiary, shrubs generally have dense foliage and many small leafy branches growing close together. Many shrubs respond well to renewal pruning, in which hard cutting back to a 'stool' results in long new stems known as "canes". Other shrubs respond better to selective pruning to reveal their structure and character. Shrubs in common garden practice are generally broad-leaved plants, though some smaller conifers such as Mountain Pine and Common Juniper are also shrubby in structure. Shrubs can be either deciduous or evergreen.

Pinnate

Pinnate is a term used to describe feather-like or many-divided features arising from both sides of a common axis in plant or animal structures, and comes from the Latin word pinna for "feather". A similar term is pectinate, which refers to a comb-like arrangement of parts (arising from one side of an axis). The term contrasts somewhat with palmate, in which the parts or structures radiate out from a common point. palmate Botanically, the term describes an arrangement of discrete structures (such as leaflets, veins, lobes, branches, or appendages) arising at multiple points along a common axis. For example, once-divided leaf blades having leaflets arranged on both sides of a rachis are pinnately compound leaves. Many palms (notably the feather palms) and most cycads and grevilleas have pinnately divided leaves. Most species of ferns have pinnate or more highly divided fronds, and ferns the leaflets are typically referred to as "pinnae" (singular "pinna"). Plants with pinnate leaves are sometimes colloquially called "feather-leaved". pinnatifid – leaves with pinnate lobes that are not discrete, remaining sufficiently connected to each other that they are not separate leaflets. paripinnate – pinnately-compound leaves in which leaflets are born in pairs along the rachis without a single terminal leaflet; also called "even-pinnate". imparipinnate – pinnately-compound leaves in which there is a lone terminal leaflet rather than a terminal pair of leaflets; also called "odd-pinnate". bipinnate – pinnately-compound leaves in which the leaflets are themselves pinnately-compound; also called "twice-pinnate". tripinnate – pinnately-compound leaves in which the leaflets are themselves bipinnate; also called "thrice-pinnate". ---- The fish, Platax pinnatus, is known as the pinnate spadefish or pinnate batfish. Category:Plant morphology

Sepal

A sepal is a tepal (a segment) of the calyx of a flower. The calyx is the outer part of the perianth, which comprises the sterile inner and outer tepals that are usually differentiated into petals and sepals. The term tepal is usually applied when the petals and sepals are not differentiated. However, in a "typical" flower the sepals are green and lie under the more conspicuous petals. When the flower is in bud, the sepals enclose and protect the more delicate floral parts within. The number of sepals in a flower (called merosity) is indicative of the plant's classification: eudicots having typically four or five sepals and monocots and palaeodicots having three, or some multiple of three, sepals. There exists considerable variation in form of the sepals among the flowering plants. Often the sepals are much reduced, appearing somewhat awn-like, or as scales, teeth, or ridges. Examples of flowers with much reduced perianths are found among the grasses. In some flowers, the sepals are fused towards the base, forming a calyx tube. This floral tube can include the petals and the attachment point of the stamens. Category: Plant morphology

Stamen

]] The stamen is the male organ of a flower. Each stamen generally has a stalk called the filament, and, on top of the filament, an anther. The anther is usually composed of four pollen sacs, which are called microsporangia. The development of the microsporangia and the contained haploid spores (called pollen-grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated. Typical flowers have six stamens inside a perianth (the petals and sepals together), arranged in a whorl around the carpel (pistil). But in some species there are many more than six present in a flower (see, for example, the spider tree flower, below). Collectively, the stamens are called an androecium (from Greek andros oikia: man's house). They are positioned just below the gynoecium. The anthers are bilocular, i.e. they have two locules. Each locule contains a microsporangium. The tissue between the locules and the cells is called the connective. In an immature, unopened flower bud, the filaments are still short. Their function is then to transport nutrients to the developing pollen. They start to lengthen once the bud opens. The anther can be attached to the filament in two ways:
- basifixed : attached at its base to the filament; this gives rise to a longitudinal dehiscence (opening along its length to release pollen)
- versatile : attached at its center to the filament; pollen is then released through pores (poricidal dehiscence). nutrient Stamens can be connate (fused or joined in the same whorl):
- monadelphous : fused into a single, compound structure
- diadelphous : joined partially into two androecial structures
- synantherous : only the anthers are connate (such as in the Asteraceae) Stamens can also be adnate (fused or joined from more than one whorl):
- epipetalous : adnate to the corolla
- didynamous : occurring in two pairs of different length
- tetradynamos : occurring as a set of six filaments with two shorter ones
- exserted : extending beyond the corolla
- included : not extending from the corolla.

Plant sexuality

:Main article: Plant sexuality In the typical flower (that is, the majority of flowering plant species) each flower has both a pistil and stamens. Bisexual plants are called hermaphrodites or perfect flowers. In some species, however, the flowers are unisexual with only either male or female parts (monoecious = on the same plant; dioecious = on different plants). A flower with only male reproductive parts is called androecious. A flower with only female reproductive parts is called gynoecious. A flower having only functional stamens is called a staminate flower. An abortive or rudimentary stamen is called a staminodium, such as in Scrophularia nodosa. The pistil and the stamens of orchids are fused into a column. The top part of the column is formed by the anther. This is covered by an anther cap.

Ovary

Ovaries are egg-producing reproductive organs found in female organisms.

Mammalian ovary

Ovaries are part of the vertebrate female reproductive system. Normally, a female will have two ovaries, each performing two major functions: producing eggs and secreting hormones. Ovaries in females are homologous to testes in males. Most birds have only one functioning ovary; snakes have two, one in front of the other. As female mammals develop within the womb, each ovary develops a number of immature eggs associated with groups of other cells called follicles. While mammals were thought to develop their entire supply of eggs prenatally and soon after birth, new evidence from laboratory mice has called this into question, showing that female mice in fact produce new eggs throughout their reproductive lifetime. However, there is no direct evidence showing that human females produce new eggs after birth. As the animal (or person) becomes reproductively mature (the process called puberty in humans), eggs will periodically mature and be released from the ovary (a process called ovulation) so that they will be available for fertilization by sperm. A fertilized egg resulting from union with a sperm becomes a zygote and then an embryo as it develops. embryo Animal and human ovaries also produce various steroid and peptide hormones. Estrogen and progesterone are the most important of these in mammals. These hormones induce and maintain the physical changes of puberty and the secondary sex characteristics. They support maturation of the uterine endometrium in preparation of implantation of a fertilized egg. They provide signals to the hypothalamus and pituitary that help maintain the menstrual cycle. Estrogen plays an important role in maintaining subcutaneous fat, bone strength, and some aspects of brain function. In humans, an egg launched from an ovary has to traverse a slight space before entering the fallopian tube and moving gradually down to the uterus. If fertilized, it implants itself into the lining of the uterus and develops as the pregnancy continues. If the fertilized egg settles into the fallopian tube instead of the uterus an ectopic pregnancy will result. Ectopic pregnancy can also happen if a fertilized egg settles onto the cervix or onto the ovary itself, or if a fertilized egg passes through the gap between the ovary and the fallopian tube into the abdomen. If the egg fails to release from the follicle in the ovary an ovarian cyst may form. Small ovarian cysts are common in healthy women but large cysts can be an advanced manifestation of polycystic ovary syndrome.

Flowering plant ovary

penis In the flowering plants, an ovary is the part of the carpel which holds the ovule(s). After pollination, the ovary will grow into the fruit, while the ovule(s) become the seed(s). Some wind pollinated flowers have much reduced and modified ovaries. The carpels together are called gynoecium.

China

to protect the north from nomadic invaders and has been rebuilt several times since.]] China () refers to a number of states and cultures that have existed and are viewed as having succeeded one another in continental East Asia, dating back at least 3,500 years. China as it exists today has been variously described in different points of view as a single civilization or multiple civilizations, as a single state or multiple states, and as a single nation or multiple nations. With one of the world's longest periods of mostly uninterrupted civilization and the world's longest continuously used written language system, China's history has been largely characterized by repeated divisions and reunifications amid alternating periods of peace and war, and violent imperial dynastic change. The country's territorial extent expanded outwards from a core area in the North China Plain, and varied according to its moving fortunes to include multiple regions of East, Northeast, and Central Asia. For centuries, Imperial China was also one of the world's most technologically advanced civilizations, and East Asia's dominant cultural influence, with an impact lasting to the present day throughout the region. By the nineteenth and early twentieth centuries, however, China's political, economic, and military influence declined relative to growing regional power Japan and the influence of Western powers. Semi-colonialism developed by the late nineteenth century in parts of China, and the country was invaded by the Empire of Japan during World War II. The imperial system in China ended with the establishment of the Republic of China (ROC) under Sun Yat-sen in 1912; however, the next four decades of ROC rule were marred by warlord control, the Second Sino-Japanese War (WWII), and the Chinese Civil War which pitted Chinese Nationalists against the Communist forces. After its victory in the Chinese Civil War, the Communist Party of China under Mao Zedong established the People's Republic of China (PRC) in 1949, forcing the Republic of China (ROC) to retreat to the island of Taiwan, which it had governed since the end of World War II. Since then, the ROC has maintained administrative control over Taiwan, the Pescadores, several islands off the coast of Fujian province, and some islands in the South China Sea.

Terminology

"Zhongguo"

South China Sea China is called Zhongguo in Mandarin Chinese (Simplified: 中国, Traditional: 中國; also romanized as Jhongguo or Chung-kuo), which is usually translated as "Middle Kingdom", but could also be translated as "Central State" or "Central Country". Zhong (中) means "middle" or "center" while guo (国 or 國) means "country," "kingdom," "state," or "land", referring to the claim that China stood at the centre of that society's "known world", surrounded by lesser tributary states. The term has not been used consistently throughout Chinese history, however, and carries certain cultural and political connotations both positive and negative, some ideological, and early states considered part of Chinese history are not called "Zhongguo". During the Spring and Autumn Period, it was used only to describe the states politically descended from the Western Zhou Dynasty, in the Yellow River (Huang He) valley, to the exclusion of states such as Chu and Qin. The "Chinese" thus defined their nation as culturally and politically distinct from - and as the axis mundi of surrounding nations; a concept that continued well into the Qing Dynasty, although being continually redefined while the central political influence expanded territorially, and its culture assimilated alien influences. Thus Zhongguo quickly came to include areas farther south, as the cultural and political unit (not yet a "nation" or "country" in the modern sense) spread in a southerly direction, including the Yangtze River and Pearl River systems, and by the Tang Dynasty it even included "barbarian" regimes such as the Xianbei and Xiongnu. Inner Mongolia, Xinjiang, and Tibet, and the island of Taiwan, over time, came to be dominated (to a greater or lesser extent) by, or officially ruled by, imperial China, and are often included as a part of Zhongguo, though acceptance or denial of such claims remains politically controversial, especially where Zhongguo means PRC. During the Han Dynasty and before, Zhongguo had three distinctive meanings: # The area around the capital or imperial domain. The Book of Poetry explicitly gives this definition. # Territories under the direct authority of the "central" authorities. The Historical Records states: "Eight mountains are famed in the empire. Three are with the Man and Yi barbarians. Five are in Zhongguo." # The area now called the North China Plain. The Sanguo Zhi records the following monologue: "If we can lead the host of Wu and Yue (the area of southern Jiangsu and northern Zhejiang) to oppose Zhongguo, then we should break off relations with them soon." In this sense, the term is synonymous with Hua (華) and Xia (夏). During the period of division after the fall of the Han Dynasty, the term Zhongguo was subjected to transformation as a result of the surge of nomadic peoples from the northern frontier. This was doubly so after the loss of the Yellow River valley, the cradle of Chinese civilization, to these peoples. For example, the Xianbei called their Northern Wei regime Zhongguo, contrasting it with the Southern Dynasties, which they called the Yi (夷), meaning "barbarian". The southern dynasties, for their part, recently exiled from the north, called the Northern Wei Lu (虏), meaning "criminal" or "prisoner". In this way Zhongguo came to represent political legitimacy. It was used in this manner from the tenth century onwards by the competing dynasties of Liao, Jin and Song. The term Zhongguo came to be related to geographic, cultural and political identity and less to ethnic origin. The Republic of China, as it controlled mainland China, and later, the People's Republic of China, have used Zhongguo as an entity existing theoretically to mean all the territories and peoples within their political control as well as those outside of it (people in the Republic of China on Taiwan now usually use Zhongguo to refer to the PRC and use Taiwan to refer to itself). Thus it is asserted that all 56 officially recognized ethnic groups are Zhongguo ren (中國人), or Zhongguo people. Their disparate histories are collectively the history of Zhongguo.

"China"

Song in ancient times, was the imperial capital of 13 different historical dynasties (including the Han and Tang dynasties) in China.]] English and many other languages use forms of the name China (and the prefix Sino-), which is believed to have derived from the name of the Qin dynasty that first unified the country, even though it is not completely resolved and the origins are still controversial to an extent [http://www.bartleby.com/61/80/C0298000.html]. Despite the fact that the Qin dynasty was short-lived and was often regarded as overly tyrannical it unified the written language in China and gave the supreme ruler of China the title of "Emperor", hence, the subsequent Silk Road traders would identify themselves by that name. Alternate theories on the origin of the word "China" exist. In any circumstance, the word China passed through many languages along the Silk Road before it finally reached Europe and England. The Western "China", transliterated to Shina (支那) has also been used by Japanese since the nineteenth century, and has since evolved into a derogatory term in that language. The term "China" can narrowly mean China proper, or, often, China proper and Manchuria, Inner Mongolia, Tibet, and Xinjiang, a combination essentially coterminous with the 20th and 21st century political entity China; the boundaries between these regions do not necessarily follow provincial boundaries. In many contexts, "China" is commonly used to refer to the People's Republic of China or mainland China, while "Taiwan" is used to refer to the Republic of China. Informally, in economic or business contexts, "the Greater China region" (大中華地區) refers to Mainland China, Hong Kong, Macau, and Taiwan. Sinologists usually use "Chinese" in a more restricted sense, more akin to the classical usage of Zhongguo, or to the meaning of the "Han ethnic group", who make up the bulk of Mainland China. In many contexts it may be more appropriate to speak of "mainland China" (中國大陸,zhōngguó dàlù in Mandarin), especially when contrasting it with other, politically different regions like Hong Kong, Macau, and territories administered by the Republic of China (Taiwan).

History

:Main articles: History of China, History of the Republic of China (1912–1949; 1949–Present on Taiwan), History of People's Republic of China (1949–Present) History of People's Republic of China China was one of the earliest centers of human civilization. Chinese civilization was also one of the few to invent writing independently, the others being ancient Mesopotamia (Sumerians), India (Indus Valley Civilization), the Mayans, and, some hold, Ancient Egypt—though it may have been learned from the Sumerians. The first dynasty according to Chinese historical sources was the Xia Dynasty. Until scientific excavations were made at early bronze-age sites at Erlitou in Henan Province, it was difficult to separate myth from reality in regard to the existence of the Xia Dynasty. But since then, archaeologists have uncovered urban sites, bronze implements, and tombs that point to the possible existence of the Xia dynasty at the same locations cited in ancient Chinese historical texts. However, the first confirmed dynasty is the Shang, who settled along the Huang He river, dating from the 18th to the 12th centuries BC. The Shang were in turn invaded by the Zhou (12th to 5th centuries BC), whose centralized authority was slowly eroded by the ceding of state-like authority to warlords ruling small states; eventually, in the Spring and Autumn period, many strong independent states, in continuous war, paid but nominal deference to the Zhou state as the Imperial centre. They were all unified under one emperor in 221 BC by Qin Shi Huang, ushering in the Qin Dynasty, the first unified centralized Chinese state. This state, however, did not last for long, as it was way too authoritarian, destroying many sources of competition for power that were also sources of good governance and development, such as scholars and intellectuals. After the fall of authoritarian Qin Dynasty in 207 BC came the Han Dynasty which lasted until 220 AD. A period of disunion followed again. In 580, China was reunited under the Sui. Under the succeeding Tang and Song dynasties, China reached its golden age. For a long period of time, especially between the 7th and 14th centuries, China was one of the most advanced civilizations in the world in technology, literature, and art. The Song Dynasty fell to the invading Mongols in 1279. The Mongols, under Kublai Khan, established the Yuan Dynasty. A peasant named Zhu Yuanzhang overthrew the Mongols in 1368 and founded the Ming Dynasty, which lasted until 1644. After the Ming dynasty, came the Qing (Manchu) dynasty, which lasted until the overthrow of Puyi in 1911. Oftentimes regime change was violent and strongly opposed and the ruler class needed to take special measures to ensure their rule and the loyalty of the overthrown dynasty. For example, after the foreign Qing (Manchus) conquered China, because they were ever suspicious of the Han Chinese, the Qing rulers put into effect measures aimed at preventing the absorption of the Manchus into the dominant Han Chinese population. However, these restrictions proved ineffective against the assimilation of Manchus into the Chinese identity and culture. In the 18th century, China achieved a decisive technological advantage over the peoples of Central Asia, which it had been at war with for several centuries, while simultaneously falling behind Europe in that respect. This set the stage for the 19th century, in which China adopted a defensive posture against European imperialism while itself engaging in imperialistic expansion into Central Asia. See Imperialism in Asia. However the primary cause of the decline of the Chinese empire was not European and American interference, as the ethnocentric Western historians would lead many to believe. On the contrary it was a series of internal upheavals. Most prominent of these was the Taiping Civil War which lasted from 1851 to 1862. The civil war was started by an extremist believer in a school of thought partly influenced by Christianity who believed himself to be the son of God and the younger brother of Jesus. Although the imperial forces were eventually victorious, the civil war was one of the bloodiest in human history - costing at least twenty million lives (more than the total number of fatalities in the First World War). Prior to this conflict a number of Islamic Rebellions, especially in Central Asia, had occurred. Later, a second major rebellion took place, although this latter uprising was considerably smaller than the cataclysmic Taiping Civil War. This second conflict was the Boxer Rebellion which aimed to repel Westerners. Although secretly supporting the rebels, the Empress, Ci Xi, aided foreign forces in suppressing the uprising. Ci Xi, 1949.]] In 1912, after a prolonged period of decline, the institution of the Emperor of China disappeared and the Republic of China was established. The following three decades were a period of disunion — the Warlord Era, the Sino-Japanese War, and the Chinese Civil War. The latter ended in 1949 with the Communist Party of China in control of mainland China. The CPC established a communist state—the People's Republic of China—that laid claim to be the successor state of the Republic of China. Meanwhile, the disorganized and potentially corrupt ROC government of the Kuomintang fled to Taiwan, where it continued to be recognized as the legitimate government of all China by the Western bloc and the United Nations until the 1970s, when most nations and the UN switched recognition to the PRC. The United Kingdom and Portugal transferred their colonies of Hong Kong and Macau on the southern Chinese coast to the PRC in 1997 and 1999, respectively. China used in a modern context often refers to just the territory of the PRC, or to "Mainland China" (the territory of the PRC excluding Hong Kong and Macau). The PRC does not recognize the ROC, as it claims to have succeeded the ROC as the legitimate governing authority of all of China including Taiwan. On the other hand, the ROC—while never formally renouncing its earlier claims or changing official maps that show its territory as including both the modern-day PRC, Mongolia and Tibet—has moved away from this former identity representing its rule over all of China, and increasingly identifies itself as Taiwan. The PRC has historically resisted the ROC's identification of itself as Taiwan, especially in light of the movement supported by residents of Taiwan and others who advocate Taiwan's identity as an independent political entity. Significant disputes persist as to the nature and extent of China, possible Chinese reunification and the political status of Taiwan.

Chinese Pre-history

Archeological evidence suggests that the earliest occupants in China date as long as 2.24 million to 250,000 years ago by an ancient human relative (hominin) known as Homo erectus. One particular cave in Zhoukoudian (now known as Peking) has fossilised evidence dating to 300,000 and 550,000 years old. Evidence of primitive stone tool technology and animal bones in association to H. erectus have been studied since the late 18th century to 19th century in various areas of Eastern Asia including Indonesia (in particular the Island of Java) and Malaysia. Originally it is thought that these early hominis first evolved in Africa during the Pleistocene. It is thought that human evolution first took place in Africa expanding 7 million years. By 2 million years ago the first wave of migration from the species in association with H. erectus settled into various areas in the Old World. Fully modern humans (homo sapiens) are believed to originally have evolved roughly 200,000 and 168,000 years ago in Ethiopia or Southern Africa (ei. Homo sapiens idaltu). By 100,000 to 50,000 years ago modern human beings settled in all parts of the Old world (including the New World, Americas 25,000 to 11,000 BCE). By less than 100,000 years ago all proto-human populations disappeared as modern humans took over or drove other human species into extinction. It remains a controversial subject to whether fully modern humans evolved from separate H. erectus populations (known as "multiregional") as some evidence in ancient bones show a transitional change from H. erectus to H. sapiens having archaic features. However it is now more widely accepted that all modern humans genetically share a direct ancestor, a female nicknamed "Mitochondrial Eve" from Eastern Africa 150,000 years BCE. This model is known as Mitochondrial Eve Hypothesis. The earliest evidence examples of fully modern humans in China come from Liujiang, China where a cranium dates 67,000 years BCE. Another is a partial skeleton from Minatogawa being just 18,000 years old.

Political history

Before unification by the Qin Dynasty in 221 BC, "China" did not exist as a coherent entity. The Chinese civilization consisted of a patchwork of several states, each ruled by a king (王), duke (公), marquess (侯), or earl (伯). Although there was a central king who held nominal power, and powerful hegemons sometimes held considerable influence, each state was ruled as an independent political entity. This is also the time of the beginnings of Confucian philosophy and that of many other philosophies that greatly influenced Chinese philosophy-political thought. This ended with the Qin Dynasty unification, during which the office of the emperor was set up, and a system of bureaucratic administration established. After the Qin, China experienced about 13 more dynasties, many of which continued the extensive system of kingdoms, dukedoms, earldoms, and marquisates. The territory varied with several expansions and contractions depending on the strength of each emperor and dynasty. However the emperor had ultimate, supreme, and unquestionable authority as the political and religious leader of China. The emperor also consulted civil and martial ministers, especially the prime minister. Political power sometimes fell into the hands of powerful officials, eunuchs, or imperial relatives, often at the expense of a child heriditary emperor. This happened especially since the emperor often was many layers of power removed from the outside world, making him susceptible to manipulation because his sources for information could manipulate that information causing him to make incorrect decisions, especially when their age at becoming emperor often had no bottom limit, with rule passing heriditarily but also given "in trust" to another relative. Political relations with dependencies (tributary kingdoms) were maintained by international marriages, military aids, treaties, and gifts. (see section "Geography, Political" below for examples), Luoyang, Chang'an (today's Xi'an), Nanjing, and Beijing are the four cities most commonly designated as capitals of China over the course of history. Chinese was the official language, though periods of Mongol and Manchu conquest saw the arrival of Mongol and Manchu as alternate official languages. On January 1, 1912, the Republic of China (ROC) was established, signaling the end of the Manchu-dominated Qing Empire. Sun Yat-sen of the Kuomintang (KMT or Nationalist Party), was proclaimed provisional president of the republic. However, Yuan Shikai, a former Qing general who had defected to the revolutionary cause, soon forced Sun to step aside and took the presidency for himself (formally it was a negotiation where Sun agreed to step aside for what was then perceived as a strong reformer, Yuan). Before long, Yuan attempted to have himself proclaimed emperor of a new dynasty; however, he died soon of natural causes before fully taking power over all of the Chinese empire. After Yuan's downfall, China was politically fragmented, with an internationally-recognized, but virtually powerless, national government seated in Beijing (thus failing to fit the definition of a state). Warlords in various regions exercised actual control over their respective territories. state In the late 1920s, the Kuomintang, under Chiang Kai-shek, was able to reunify the country under its own control, moving the nation's capital to Nanjing and implementing "political tutelage", an intermediate stage of political development outlined in Sun Yat-sen's program for transforming China into a modern, democratic state. Effectively, political tutelage meant one-party rule by the Kuomintang with heavy Leninist influences. Ironically, both the Kuomintang and the CCP have heavy Leninist influences. In 1947, constitutional rule was established, but because of the ongoing Chinese Civil War between the Kuomintang and the Communist Party of China (CPC), many provisions of the 1947 ROC constitution were never put into actual practice on the mainland. By early 1950, the CPC had defeated the Kuomintang on the mainland, and the ROC government retreated to the island of Taiwan. Beginning in the late 1970s, Taiwan began the implementation of full, multi-party, representative democracy in the territories still under ROC control (i.e., Taiwan Province, Taipei, Kaohsiung and some offshore islands of Fujian province). Today, the political scene in the ROC is vibrant, with active participation by all sectors of society. But rather than the usual conservative-liberal policy distinctions that are the hallmarks of most democracies around the world, the main cleavage in ROC politics is the unification with China in the long-run vs. formal independence issue. However, Greens are generally more liberal (i.e. more environmentally friendly) and Blues are generally regarded as more conservative. environmentally friendly Meanwhile, Mao Zedong, the leader of the communists, proclaimed the People's Republic of China (PRC) on October 1, 1949 in Beijing, saying China had stood up. From the beginning, the PRC has been a dictatorial one-party state under the Communist Party. However, post-1978 reforms have led to the relaxation, in varying degrees, of party control over many areas of society. Nonetheless, the Communist Party still has absolute control over political aspects of society, and it continuously seeks to eradicate threats to its rule. Examples of this include the jailing of political opponents and journalists, general control of the press, regulation of religions and other non-party organizations, censorship of the press, literature and film, and suppression of independence/secessionist movements. In 1989, a popular demonstration held in Beijing at Tiananmen Square was violently put to an end by the Chinese government. Tiananmen_Square_protests_of_1989 The attempted eradication of the Falun Gong movement is also held by its supporters to be motivated by fear of Falun Gong's growing influence. Today, however, there is much more freedom in intellectual thought in non-political areas and propaganda, while still continuing, has lessened.

Territory

Historical overview

propaganda The Zhou Dynasty, which preceded the unification of China by Shi Huangdi, was originally the region around the Yellow River. Since then, the territory has expanded outward in all directions, and was largest during the Tang, Yuan, and Qing dynasties. The Qing Dynasty included parts of modern Russian Far East and Central Asia (west of Xinjiang). Xinjiang Along with provincial administrators, some foreign monarchs sent envoys to offer gifts to the Emperor of China and the Emperor returned compliments to them. The Chinese thought that the barbarians attached themselves to the virtue of the Emperor, while the foreign governments sometimes disagreed. Since the end of the 19th century, China has tried to reinterpret this relationship as suzerainty or suzerainty-dependency, but this no longer has any real conception in modern international political theories. The Qing Empire reduced the territorial value of the Great Wall of China as a barrier of China proper after they merged their homeland (Manchuria) north of the wall with China proper south of it. In 1683 after the surrender of the Kingdom of Tungning established by Koxinga, Taiwan including the Pescadores became a part of the Qing Empire, originally as one prefecture, then two, and later a province. Taiwan was subsequently ceded to Japan after the first Sino-Japanese War in 1895. At the end of the second Sino-Japanese War in 1945, Japan relinquished the sovereignty of the island in the San Francisco Peace Treaty, and the Republic of China took over. Since then, the de jure sovereignty of Taiwan has been under dispute between the PRC, and the now democratic ROC and Taiwan independence supporters.

Historical political divisions

Historically, top-level political divisions of China have altered as the administration changed. Top levels included circuits and provinces. Below that, there have been prefectures, subprefectures, departments, commanderies, districts, and counties. Recent divisions also include prefecture-level cities, county-level cities, towns and townships (see below for examples). Historically, most Chinese dynasties were based in the historical heartlands of China, known by the politically-correct term of China proper (since it doesn't include places it doesn't control, such as Mongolia or Taiwan). Various dynasties also exhibited expansionism by engaging in incursions into more peripheral territories like Inner Mongolia, Manchuria, Xinjiang, and Tibet. The Manchu-established Qing Dynasty and its successors, the Republic of China and the People's Republic of China cemented the incorporation of these territories into China. These territories are separated by borders that are vague at best, and do not correspond well to contemporary political divisions. China proper is generally thought to be bounded by the Great Wall and the edge of the Tibetan plateau; Manchuria and Inner Mongolia are found to the north of the Great Wall of China, and the boundary between them can either be taken as the present border between Inner Mongolia and the northeast Chinese provinces, or the more historic border of the World War II-era puppet state of Manchukuo; Xinjiang's borders correspond to today's administrative Xinjiang; and historic Tibet is conceived as occupying all of the Tibetan Plateau. China is also traditionally thought of as comprising North China (北方) and South China (南方), the geographic boundary between which north and south is largely generalized as Huai River (淮河) and Qinling Mountains (秦岭).

Geography and climate

Qinling Mountains

China within East Asia. ([http://www.cia.gov/cia/publications/factbook/reference_maps/pdf/asia.pdf PDF])

China is composed of a vast variety of highly different landscapes, with mostly plateaus and mountains in the west, and lower lands on the east. As a result, principal rivers flow from west to east, including the Yangtze (central), the Huang He (central-east), and the Amur (northeast), and sometimes toward the south (including the Pearl River, Mekong River, and Brahmaputra), with most Chinese rivers emptying into the Pacific. Most of China's arable lands lie along the two major rivers, the Yangtze and the Huang He, and each are the centers around which are founded China's major ancient civilizations. In the east, along the shores of the Yellow Sea and the East China Sea are found extensive and densely populated alluvial plains; the shore of the South China Sea is more mountainous and southern China is dominated by hill country and lower mountain ranges. To the west, the north has a great alluvial plain, and the south has a vast calcareous tableland traversed by hill ranges of moderate elevation, with the Himalayas, containing the highest point Mount Everest. The northwest also has high plateaus among more arid desert landscapes such as the Takla-Makan and the Gobi Desert, which has been expanding. Due to a prolonged drought and perhaps poor agricultural practices, dust storms have become usual in the spring in China. Dust blows all the way to southern China, Taiwan, and has even been measured on the West Coast of the United States. United States native to the bamboo forests of central and southern China.]] During many dynasties, the southwestern border of China has been the high mountains and deep valleys of Yunnan, which separate modern China from Burma, Laos and Vietnam. The climate of China varies greatly. The northern zone (within which lies Beijing) has a climate with winters of Arctic severity. The central zone (within which Shanghai is situated) has a generally temperate climate. The southern zone (within which lies Guangzhou and other southern provinces) has a generally subtropical climate. The Palaeozoic formations of China, excepting only the upper part of the Carboniferous system, are marine, while the Mesozoic and Tertiary deposits are estuarine and freshwater or else of terrestrial origin. Groups of volcanic cones occur in the Great Plain of north China. In the Liaodong and Shandong Peninsulas, there are basaltic plateaux.

Demographics

Shandong.]] Over a hundred ethnic groups have existed in China. In terms of numbers, however, the pre-eminent ethnic group in China is the Han, which is a group so diverse in its culture and language that some conceive of it as a larger overarching group bringing together many smaller, distinct ethnic groups sharing common traits in language and culture. Throughout history, many ethnic groups have been assimilated into neighbouring ethnicities or disappeared without a trace. Several previously distinct ethnic groups have been Sinicized into the Han, causing its population to increase dramatically; at the same time, many within the Han identity have maintained distinct linguistic and cultural traditions, though still identifying as Han. Many times in the past millenia many foreign groups have, in turn, shaped Han language and culture, for example the queue is a pig tail hairstyle strictly enforced by the Manchurians on the Han populace. The term Zhonghua Minzu is sometimes used to describe a notion of a "Chinese nationality" transcending ethnic divisions. The government of the People's Republic of China now officially recognizes a total of 56 ethnic groups, of which the largest is the Han Chinese. China's overall population is 1.3 billion. With the global human population currently estimated at about 6.4 billion, China is home to approximately 20%, or one-fifth of the human species, homo sapiens. The lack of birth control and promotion of population growth during the rule of Mao Zedong resulted in a demographic explosion, culminating in over 1.3 billion people today. As a response to the problems this is causing, the government of the PRC has enacted a birth control policy, commonly known as the One-child policy. The Han speak several mutually unintelligible tongues, classified by modern linguists as being separate languages, but regarded within the Chinese languages as "dialects" or "local languages" (topolects) within a single Chinese language (the word for "area languages" has an implication of dialect rather than a separate language, although on the basis of use, these topolects can be found to be separate and mutually unintelligible, and are so classified by many linguists). The various spoken varieties of Chinese share a common written standard, "Vernacular Chinese" or "baihua", which has been used since the early 20th Century and is based on Standard Mandarin, the standard spoken language, in grammar and vocabulary. In addition, another, more ancient written standard, Classical Chinese, was used for writing Chinese by the literati for thousands of years before the 20th Century. Classical Chinese is no longer the predominant form of written Chinese, though it continues to be a part of high school curricula and is hence intelligible to some degree to many Chinese people. Other than Standard Mandarin, spoken variants are usually not written; the exception is Standard Cantonese, which is sometimes written as Written Cantonese in informal contexts. Written Cantonese.]]

Culture

Religion

The major religions of China are:
- Taoism - exact numbers unknown
- Buddhism - exact numbers unknown [about 8%]
- Christianity - 2 to 4% (this is a Western number, the Chinese official number is much smaller than 1%)
- Islam - 1% to 2%
- Falun Gong - exact numbers unknown (claim not to be a "religion", though from a scholarly perspective is a spiritual practice, claimed numbers of followers of the Falun Dafa are also regarded as unreliable) While the People's Republic of China is officially atheist it does allow religion under strict supervision. Historically, Taoism and Buddhism has been the dominant religion of Chinese societies, and continues to be so in Chinese societies outside of direct PRC control. In recent years, Falun Gong, a spiritual practice drawing upon Buddhism and Taoism, has attracted great controversy after the government of the People's Republic of China labeled it an evil cult and began an attempt to eradicate it. The Falun Gong itself denies that it is a cult or a religion, even though there is solid evidence that determines Falun Gong as a rather" abormal" cult, several members have been seen to burn themselves alive even before the Chinese government has reacted to Falun Gong, unfortuantely, most people are oblivious of this fact and even a majority of members are oblivious to this. The Falun Gong says that it has approximately 70-100 million followers, which is a bit higher than estimates by outside groups, though exact numbers are unknown. They regularly protest against their suppression, both domestically and internationally.

Arts, scholarship, and literature

Falun Gong.]] Chinese literature has a long and prolific continuous history, in part because of the development of printmaking during the Song Dynasty. Before that, manuscripts of the Classics and religious texts (mainly Confucian, Taoist, and Buddhist) were manually written by ink brush (previously scratching shells) and distributed. Academies of scholars sponsored by the empire were formed to comment on these works in both printed and written form. Members of royalty frequently participated in these discussions. Tens of thousands of ancient written documents are still extant and more, from oracle bones to Qing edicts, are discovered each day, which had been formally ground up for use in Chinese medicine. oracle bones For centuries, opportunity for economic and social advancement in China could be provided by high performance on the imperial examinations. This led to a meritocracy, though in practice this was possible only among those who were not female or too poor to afford test preparation, as doing well still required tutorship. Nevertheless it was a system distinct from the European system of blood nobility. Imperial examinations required applicants to write essays and demonstrate mastery of the Confucian classics. Those who passed the highest level of the exam became elite scholar-officials known as jinshi, a highly esteemed socio-economic position. Chinese philosophers, writers, and poets have been, for the most part, highly respected, and played a key role in preserving and promoting the culture of the empire. Some classical scholars, however, were noted for their daring depictions of lives of the common people, often to the displeasure of authorities. (See List of Chinese authors, and List of Chinese language poets). The Chinese have created numerous musical instruments, such as the zheng, xiao, and erhu, that have spread throughout East and Southeast Asia, and especially areas under its influence. The sheng is the basis for several Western free-reed instruments. Chinese characters have had many variants an
