Prehistory (Latin, præ = before Greek, ιστορία = history) is a term often used to describe the period before written history. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly History is the study of the past particularly the written record Those who study history as a Profession are called Historians Etymology Recorded history can be defined as History that has been written down or recorded by the use of Language, whereas History is a more general term referring Paul Tournal originally coined the term Pré-historique in describing the finds he had made in the caves of southern France. Southern France (or the South of France) colloquially known as Le Midi, is a loosely defined geographical area consisting of the regions of France that It came into use in French in the 1830s to describe the time before writing, and was introduced into English by Daniel Wilson in 1851. French ( français,) is a Romance language spoken around the world by 118 million people as a native language and by about 180 to 260 million people English is a West Germanic language originating in England and is the First language for most people in the United Kingdom, the United States Sir Daniel Wilson ( 5 January, 1816 &ndash 6 August, 1892) was a British-born Canadian Archaeologist, Ethnologist
Prehistory can be said to date back to the beginning of the universe itself, although the term is most often used to describe periods when there was life on Earth; dinosaurs can be described as prehistoric animals and cavemen are described as prehistoric people. The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy Life is a state that distinguishes Organisms from non-living objects such as non-life and dead organisms being manifested by growth through Metabolism EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 A caveman is a popular Stock character based upon Stereotyped concepts of the way in which early prehistoric Humans or Homininans may have looked and Usually the context implies what geologic or prehistoric time period is discussed, f.

The Miocene is a geological epoch of the Neogene period and extends from about 23 5 Million years ago, or "Middle Palaeolithic Homo sapiens", 200000 - 30000 years ago. The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe,
Because, by definition, there are no written records from prehistoric times, (or at least there are none known to still exist down to this day) the information we know about the time period is informed by the fields of paleontology, biology, palynology, geology, archaeoastronomy, anthropology, archaeology and other natural and social sciences. Palaeontology redirects here For the Scientific journal, see Palaeontology (journal. Foundations of modern biology There are five unifying principles Palynology is the science that studies contemporary and fossil Palynomorphs including Pollen, Spores, Dinoflagellate Cysts Acritarchs Geology (from Greek γη gê, "earth" and λόγος Logos, "speech" lit Archaeoastronomy (also spelled archeoastronomy) is the study of how peoples in the past "have understood the phenomena in the sky how they used phenomena Anthropology (/ˌænθɹəˈpɒlədʒi/ from Greek grc ἄνθρωπος anthrōpos, "human" -λογία -logia) is the study of Archaeology, archeology, or archæology (from Greek grc ἀρχαιολογία archaiologia – grc ἀρχαῖος archaīos In societies where the introduction of writing is relatively recent, oral histories, knowledge of the past handed down from generation to generation, contain records of "prehistoric" times. Oral history preservation is the field that deals with the care and upkeep of Oral history materials whatever format they may be in
The term became less strictly defined in the 20th century as the boundary between history (interpretation of written and oral records) and other disciplines became less rigid. Indeed today most historians rely on evidence from many areas and do not necessarily restrict themselves to the historical period and written, oral or other symbolically encoded sources of communication; in addition, the term "history" is increasingly used in place of "prehistory" (e. g. History of Earth, history of the universe). The history of Earth covers approximately 46 billion years (4567000000 years from Earth ’s formation out of the Solar nebula to the present This timeline of the Big Bang describes the events according to the Scientific theory of the Big Bang, using the cosmological time parameter of Comoving coordinates Nevertheless, the distinction remains important to many scholars, particularly in the social sciences. The primary researchers into Human prehistory are prehistoric archaeologists and physical anthropologists who use excavation, geographic survey, and scientific analysis to reveal and interpret the nature and behavior of pre-literate and non-literate peoples.

Human prehistory differs from history not only in terms of chronology but in the way it deals with the activities of archaeological cultures rather than named nations or individuals. Definition A chronology may be either relative &mdashthat is locating related events relative to each other&mdashor ''absolute'' &mdashlocating In addition to its usual meaning in Social science, in Archaeology, the term culture is also used in reference to several related concepts unique to A nation is a Human Cultural and Social Community. In as much as most members never meet each other yet feel a common bond it may be considered As commonly used, individual refers to a Person or to any specific object in a collection Restricted to material remains rather than written records (and indeed only those remains that have survived), prehistory is anonymous. Because of this, the reference terms used by prehistorians such as Neanderthal or Iron Age are modern, arbitrary labels, the precise definition of which is often subject to discussion and argument. The Neanderthal (neɪˈændərtɑːl also with /niː-/ and /-θɔːl/ or Neandertal, is an extinct member of the Homo genus that is known from This article is about the archaeological period known as the Iron Age for the mythological Iron Age see Ages of Man.

"Paleolithic" means "Old Stone Age. " This was the earliest period of the Stone Age. The Stone Age is a broad prehistoric time period during which Humans widely used stone for toolmaking The Lower Paleolithic predates Homo sapiens, beginning with Homo habilis and the earliest use of stone tools some 2. The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age. Homo habilis (ˈhoʊmoʊ ˈhæbəlɪs ("handy man" "skillful person" is a Species of the genus Homo, which lived 5 million years ago. Homo sapiens originated some 200,000 years ago, ushering in the Middle Paleolithic. The term Archaic Homo sapiens refers generally to the earliest members of the species Homo sapiens. The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe,
Sometime during the Middle Paleolithic, humans also developed language, music, early art, as well as systematic burial of the dead. The origin of language ( glottogony) is a topic that has attracted considerable speculation throughout human history In the History of music, prehistoric music (previously called primitive music) is all Music produced in preliterate cultures ( Prehistory --> In the history of art prehistoric art is all art produced in preliterate cultures (prehistory beginning somewhere in very late geological history See also Prehistoric religion The origin and early Development of religion falls into the Paleolithic.
Humans spread from East Africa to the Near East some 80 millennia ago, and further to southern Asia and Australasia some 60 millennia ago, northwestwards into Europe and eastwards into Central Asia some 40 millennia ago, and further east to the Americas from ca. Australasia is a Region of Oceania: New Zealand, Australia, Papua New Guinea, and neighbouring Islands in the Pacific Central Asia is a region of Asia from the Caspian Sea in the west to central China in the east and from southern Russia in the north to northern Pakistan in the south The Americas are the lands of the Western hemisphere or New World, consisting of the Continents of North America and South America 15 millennia ago. The Upper Paleolithic is taken to begin some 40 millennia ago, with the appearance of "high" culture. The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age as it is understood in Europe Africa Expansion to North America and Oceania took place at the climax of the most recent Ice Age, when today's temperate regions were extremely inhospitable. An ice age is a period of long-term reduction in the Temperature of the Earth 's surface and atmosphere resulting in an expansion of continental Ice sheets By the end of the Ice Age some 12,000 BP, humans had colonised nearly all the ice-free parts of the globe. Before Present (BP years are a time scale used in Archaeology, Geology, and other scientific disciplines to specify when events in the past occurred
Throughout the Paleolithic, humans generally lived as nomadic hunter-gatherers.

The Mesolithic period began at the end of the Pleistocene epoch, some 10,000 BP, and ended with the introduction of agriculture, the date of which varied by geographic region. The Pleistocene ('plaɪstəsin is the epoch from 18 million to 10000 years BP covering the world's recent period Agriculture refers to the production of goods through the growing of plants and fungi and the raising of domesticated Animals The study of agriculture In some areas, such as the Near East, agriculture was already underway by the end of the Pleistocene, and there the Mesolithic is short and poorly defined.

The Epipaleolithic is a term used for the "final Upper Palaeolithic industries occurring at the end of the final glaciation which appear to merge technologically into the
Regions that experienced greater environmental effects as the last ice age ended have a much more evident Mesolithic era, lasting millennia. "Last glacial" redirects here For the period of maximum glacier extent during this time see Last Glacial Maximum The last glacial period In Northern Europe, societies were able to live well on rich food supplies from the marshlands fostered by the warmer climate. Such conditions produced distinctive human behaviours which are preserved in the material record, such as the Maglemosian and Azilian cultures. Maglemosian (ca 7500 BC - ca 6000 BC) is the name given to a culture of the early Epipaleolithic period in Northern Europe. The Azilian is a name given by Archaeologists to an industry of the Epipaleolithic in northern Spain and southern France. These conditions also delayed the coming of the Neolithic until as late as 4000 BCE (6,000 BP) in northern Europe. Before Present (BP years are a time scale used in Archaeology, Geology, and other scientific disciplines to specify when events in the past occurred
Remains from this period are few and far between, often limited to middens. A midden, also known as a kitchen midden, or a shell heap, is a dump for domestic waste. In forested areas, the first signs of deforestation have been found, although this would only begin in earnest during the Neolithic, when more space was needed for agriculture. A forest is an area with a high density of Trees There are many definitions of a forest based on various criteria Deforestation is the conversion of Forested areas to non-forest land for use such as Arable land, Pasture, urban use logged area or wasteland The Neolithic (from Greek νεολιθικός — neolithikos from νέος neos, "new" + λίθος lithos Agriculture refers to the production of goods through the growing of plants and fungi and the raising of domesticated Animals The study of agriculture

The Azilian is a name given by Archaeologists to an industry of the Epipaleolithic in northern Spain and southern France. Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula.

A major change, described by prehistorian Vere Gordon Childe as the "Agricultural Revolution," occurred about the 10th millennium BCE with the adoption of agriculture. Agriculture was developed at least 10000 years ago and it has undergone significant developments since the time of the earliest cultivation Vere Gordon Childe (14 April 1892 Sydney, New South Wales –19 October 1957 Mt The Neolithic Revolution was the first Agricultural revolution &mdashthe transition from hunting and gathering communities and bands to Agriculture and Agriculture refers to the production of goods through the growing of plants and fungi and the raising of domesticated Animals The study of agriculture The Sumerians first began farming ca.

Before 1800, most populations did not belong to states. A state is a political association with effective Sovereignty over a geographic Area and representing a Population. Scientists disagree as to whether the term "tribe" should be applied to the kinds of societies that these people lived in. A tribe, viewed historically or developmentally consists of a Social group existing before the development of or outside of States Many anthropologists use Some tribal societies transformed into states when they were threatened, or otherwise impinged on, by existing states.
Agriculture made possible complex societies — civilizations. A Civilization is a society in which large numbers of people share a variety of common elements States and markets emerged. Technologies enhanced people's ability to control nature and to develop transport and communication. Nature, in the broadest sense is equivalent to the natural world, physical universe, material world or material universe. Transport or transportation is the movement of people and goods from one place to another Communication is the process of conveying information from a sender to a receiver with the use of a medium in which the communicated information is understood the same way
The term Bronze Age refers to a period in human cultural development when the most advanced metalworking (at least in systematic and widespread use) included techniques for smelting copper and tin from naturally-occurring outcroppings of copper ores, and then smelting those ores to cast bronze. Metalworking is craft and practice of working with Metals to create individual parts assemblies or large scale structures Chemical reduction, or smelting, is a form of Extractive metallurgy. Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 Tin is a Chemical element with the symbol Sn (stannum and Atomic number 50 Bronze is any of a broad range of Copper alloys, usually with Tin as the main additive but sometimes with other elements such as Phosphorus These naturally-occurring ores typically included arsenic as a common impurity. Copper/tin ores are rare, as reflected in the fact that there were no tin bronzes in Western Asia before 3,000 BC. The Bronze Age forms part of the three-age system for prehistoric societies. The three-age system refers to the Periodization of Human Prehistory into three consecutive Time periods named for their respective In this system, it follows the Neolithic in some areas of the world. The Neolithic (from Greek νεολιθικός — neolithikos from νέος neos, "new" + λίθος lithos
