Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

Rock art
–
In archaeology, rock art is human-made markings placed on natural stone, it is largely synonymous with parietal art. A global phenomenon, rock art is found in many diverse regions of the world. It has been produced in many contexts throughout history, although the majority of rock art that has been ethnographically recorded has been produced as a part of ritual. Such artworks are often divided into three forms, petroglyphs, which are carved into the surface, pictographs, which are painted onto the surface. The oldest known rock art dates from the Upper Palaeolithic period, having found in Europe, Australia, Asia. Archaeologists studying these artworks believe that they likely had magico-religious significance, Rock art continues to be of importance to indigenous peoples in various parts of the world, who view them as both sacred items and significant components of their cultural patrimony. Such archaeological sites are significant sources of cultural tourism, and have been utilised in popular culture for their aesthetic qualities. Normally found in cultures, a rock relief or rock-cut relief is a relief sculpture carved on solid or living rock such as a cliff. They are a category of art, and sometimes found in conjunction with rock-cut architecture. However, they tend to be omitted in most works on rock art, a few such works exploit the natural contours of the rock and use them to define an image, but they do not amount to man-made reliefs. Rock reliefs have been made in many cultures, and were important in the art of the Ancient Near East. Rock reliefs are generally large, as they need to be to make an impact in the open air. Most have figures that are over life-size, and in many the figures are multiples of life-size, the vertical relief is most common, but reliefs on essentially horizontal surfaces are also found. The term typically excludes relief carvings inside caves, whether natural or themselves man-made, natural rock formations made into statues or other sculpture in the round, most famously at the Great Sphinx of Giza, are also usually excluded. Reliefs on large boulders left in their location, like the Hittite İmamkullu relief, are likely to be included. The term rock art appears in the literature as early as the 1940s. It has also described as rock carvings, rock drawings, rock engravings, rock inscriptions, rock paintings, rock pictures. The defining characteristic of rock art is that it is placed on natural rock surfaces, as such, rock art is a form of landscape art, and includes designs that have been placed on boulder and cliff faces, cave walls and ceilings, and on the ground surface

Upper Paleolithic
–
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity, modern humans are believed to have emerged about 195,000 years ago in Africa. Although these humans were modern in anatomy, their lifestyle changed very little from their contemporaries, such as Homo erectus, about 50,000 years ago, there was a marked increase in the diversity of artifacts. In Africa, bone artifacts and the first art appear in the archeological record, between 45,000 and 43,000 years ago, this new tool technology spread with human migration to Europe. The new technology generated an explosion of modern humans which is believed to have contributed to the extinction of the Neanderthals. The Upper Paleolithic has the earliest known evidence of organized settlements, in the form of campsites, artistic work blossomed, with cave painting, petroglyphs, carvings and engravings on bone or ivory. The first evidence of fishing is also noted, from artifacts in places such as Blombos cave in South Africa. More complex social groupings emerged, supported by more varied and reliable food sources and this probably contributed to increasing group identification or ethnicity. By 50, 000–40,000 BP, the first humans set foot in Australia, by 45,000 BP, humans lived at 61° north latitude in Europe. By 30,000 BP, Japan was reached, and by 27,000 BP humans were present in Siberia above the Arctic Circle, at the end of the Upper Paleolithic, a group of humans crossed the Bering land bridge and quickly expanded throughout North and South America. Both Homo erectus and Neanderthals used the same crude stone tools, archaeologist Richard G. Klein, who has worked extensively on ancient stone tools, describes the stone tool kit of archaic hominids as impossible to categorize. It was as if the Neanderthals made stone tools, and were not much concerned about their final forms and he argues that almost everywhere, whether Asia, Africa or Europe, before 50,000 years ago all the stone tools are much alike and unsophisticated. These new stone-tool types have been described as being distinctly differentiated from each other, the invaders, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines. The Neanderthals continued to use Mousterian stone tool technology and possibly Chatelperronian technology and these tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40,000 years ago. Settlements were often located in valley bottoms, possibly associated with hunting of passing herds of animals. Hunting was important, and caribou/wild reindeer may well be the species of single greatest importance in the anthropological literature on hunting. Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes, burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in period, along with the fish hook, the oil lamp, rope

Stone Age
–
The Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface. The period lasted roughly 3.4 million years, and ended between 8700 BCE and 2000 BCE with the advent of metalworking, bone tools were used during this period as well but are rarely preserved in the archaeological record. The Stone Age is further subdivided by the types of tools in use. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands. The closest relative among the living primates, the genus Pan, represents a branch that continued on in the deep forest. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia. The oldest indirect evidence found of stone tool use is fossilised animal bones with tool marks, the oldest stone tools were excavated from the site of Lomekwi 3 in West Turkana, northwestern Kenya, and date to 3.3 million years old. Prior to the discovery of these Lomekwian tools, the oldest known stone tools had been found at sites at Gona, Ethiopia, on the sediments of the paleo-Awash River. All the tools come from the Busidama Formation, which lies above a disconformity, or missing layer, the oldest sites containing tools are dated to 2. 6–2.55 mya. One of the most striking circumstances about these sites is that they are from the Late Pliocene, excavators at the locality point out that. the earliest stone tool makers were skilled flintknappers. The possible reasons behind this seeming abrupt transition from the absence of tools to the presence thereof include. The species who made the Pliocene tools remains unknown, fragments of Australopithecus garhi, Australopithecus aethiopicus and Homo, possibly Homo habilis, have been found in sites near the age of the Gona tools. Innovation of the technique of smelting ore ended the Stone Age, the first most significant metal manufactured was bronze, an alloy of copper and tin, each of which was smelted separately. The Chalcolithic by convention is the period of the Bronze Age. The Bronze Age was followed by the Iron Age, the transition out of the Stone Age occurred between 6000 BCE and 2500 BCE for much of humanity living in North Africa and Eurasia. Note the Rudna Glava mine in Serbia, Ötzi the Iceman, a mummy from about 3300 BCE carried with him a copper axe and a flint knife. In regions such as Sub-Saharan Africa, the Stone Age was followed directly by the Iron Age, the Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BCE. Europe, and the rest of Asia became post–Stone Age societies by about 4000 BCE, the proto-Inca cultures of South America continued at a Stone Age level until around 2000 BCE, when gold, copper and silver made their entrance

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Aragon
–
Aragon is an autonomous community in Spain, coextensive with the medieval Kingdom of Aragon. Located in northeastern Spain, the Aragonese autonomous community comprises three provinces, Huesca, Zaragoza, and Teruel, the current Statute of Autonomy declares Aragon a nationality of Spain. Aragons northern province of Huesca borders France and is positioned in the middle of the Pyrenees, within Spain, the community is flanked by Catalonia to the east, Valencia and Castile–La Mancha to the south, and Castile and León, La Rioja, and Navarre to the west. Aragon is home to many rivers—most notably, the river Ebro, Spains largest river in volume and it is also home to the Aneto, the highest mountain in the Pyrenees. As of 2015, the population of Aragon was 1,317,847, with more than half of it living in Zaragoza. As of 2015, half of Aragons population,50. 45%, Huesca is the only other city in the region with a population greater than 50,000. The majority of Aragonese citizens,71. 8%, live in the province of Zaragoza,17. 1% in Huesca and 11. 1% in Teruel, the population density of the region is the second lowest in Spain, only 26, 8/km2, after Castilla La Mancha. Only four cities have more than 20,000 inhabitants, Zaragoza 700,000, Huesca 50,000, Teruel 35,000 and Calatayud 20,000. Spanish is the language in most of Aragon, and it is the only official language, understood. The strip-shaped Catalan-speaking area in Aragon is often called La Franja, with such a low population density large areas of Aragon remain wild and relatively untouched. It is a land of natural contrasts, both in climate and geologically, from the green valleys and snow-capped peaks of the Pyrenees to the dry plains. Aragons Pyrenees include splendid and varied mountain landscapes with soaring peaks, deep canyons, dense forests and its rugged peaks include the Aneto, the highest in the range, the misty Monte Perdido, Perdiguero, Cotiella and many others. The park is one of the last sanctuaries of birds of prey in the range. Many beautiful mountain butterflies and flowers can be seen in the summer, the principal valleys in the mountains include those of Hecho, Canfranc, Tena, Benasque and others. The green valleys hide pretty villages with nice Romanesque churches and typical Pyrenean houses with flowers on the balconies, the oldest Romanesque cathedral in Spain is located in the medieval town of Jaca in the very northern part of Huesca Province. In the Pyrenean foothills, or pre-Pyrenees, the Mallos de Riglos are a natural rock formation. Ancient castles nestle on lonely hills, the most famous being the magnificent Loarre Castle, further south, the Ebro valley, irrigated by the river Ebro, is a rich and fertile agricultural area covered with vast fields of wheat, barley and other fruit and vegetable crops. Many beautiful and little-known settlements, castles and Roman ruins dot the landscape here, some of the most notable towns here include Calatayud, Daroca, Sos del Rey Catolico, Caspe and others

Castilla-La Mancha
–
Castilla-La Mancha is a south-western European region that was part of the Kingdom of Castile. Nowadays it is established as a community of Spain. Castilla-La Mancha is bordered by Castile and León, Madrid, Aragon, Valencia, Murcia, Andalusia and it is one of the most sparsely populated of Spains autonomous communities. Albacete is the largest and most populous city and its capital city is Toledo, and its judicial capital city is Albacete. It is mostly in this region where the story of the famous Spanish novel Don Quixote by Miguel de Cervantes is situated, due to which La Mancha is internationally well-known. Although La Mancha is a windswept, battered plateau, it remains a symbol of Spanish culture with its vineyards, sunflowers, mushrooms, olive plantations, windmills, Manchego cheese, the history of Castilla-La Mancha has been significant. Its origin lay in the Muslim period between the 8th and 14th century, Castilla-La Mancha was the region of many historical battles between Christian crusaders and Muslim forces during the period from 1000 to the 13th century. It was also the region where the Crown of Castile and Aragon were unified in 1492 under Queen Isabel, Castilla-La Mancha is the successor to New Castile, which in turn traces back to the Muslim Taifa of Toledo, one of the taifas of Al Andalus. Alfonso VI conquered the region from the Muslims, taking Toledo in 1085, the Reconquista took Cuenca in 1177. That victory assured Castilian domination of the region and hastened the decline of the Almohad Dynasty, from the time of the Reconquista, Castilla-La Mancha formed part of the Kingdom of Castile. Four centuries later, in 1605, Cervantes Don Quixote gave the world a picture of La Mancha. In 1785, the organization by the reformer Floridablanca divided the region into the provinces of Cuenca, Guadalajara, Madrid, La Mancha. Albacete, Chinchilla, Almansa, Hellín and Yeste, however, Albacete, in turn, also incorporated parts of the territories of the old provinces of Cuenca and Murcia. Albacete was administered as part of the Region of Murcia until the 1978 configuration of autonomous regions, the Autonomous Community of Castilla-La Mancha dates from November 15,1978, as one of the many autonomous regions defined by the Spanish central government. The new, hyphenated name constituted an effort to two distinct regionalisms, that of the larger Castilla and that of the smaller onetime province of La Mancha. The Statute of Autonomy of Castilla–La Mancha was approved August 10,1982, Castilla-La Mancha is divided into 5 provinces named after their capital cities. 496 of these have less than 500 inhabitants,231 have between 501 and 2,000 inhabitants,157 between 2,000 and 10,000 inhabitants, and only 35 have more than 10,000 inhabitants. The municipalities in the north are small and numerous, while in the south they are larger and fewer and this reflects different histories of how these sub-regions were repopulated during the Reconquista

Neolithic
–
It ended when metal tools became widespread. The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops, the beginning of the Neolithic culture is considered to be in the Levant about 10, 200–8800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called proto-Neolithic is now included in the Pre-Pottery Neolithic between 10,200 and 8800 BC. By 10, 200–8800 BC, farming communities arose in the Levant and spread to Asia Minor, North Africa, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. Early Neolithic farming was limited to a range of plants, both wild and domesticated, which included einkorn wheat, millet and spelt, and the keeping of dogs, sheep. By about 6900–6400 BC, it included domesticated cattle and pigs, the establishment of permanently or seasonally inhabited settlements, not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order, the earliest farming societies in the Near East did not use pottery. Early Japanese societies and other East Asian cultures used pottery before developing agriculture, unlike the Paleolithic, when more than one human species existed, only one human species reached the Neolithic. The term Neolithic derives from the Greek νέος néos, new and λίθος líthos, stone, the term was invented by Sir John Lubbock in 1865 as a refinement of the three-age system. In the Middle East, cultures identified as Neolithic began appearing in the 10th millennium BC, early development occurred in the Levant and from there spread eastwards and westwards. Neolithic cultures are attested in southeastern Anatolia and northern Mesopotamia by around 8000 BC. The total excavated area is more than 1,200 square yards, the Neolithic 1 period began roughly 10,000 years ago in the Levant. A temple area in southeastern Turkey at Göbekli Tepe dated around 9500 BC may be regarded as the beginning of the period. This site was developed by nomadic tribes, evidenced by the lack of permanent housing in the vicinity. At least seven stone circles, covering 25 acres, contain limestone pillars carved with animals, insects, Stone tools were used by perhaps as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9500–9000 BC have been found in Jericho, Israel, Gilgal in the Jordan Valley, the start of Neolithic 1 overlaps the Tahunian and Heavy Neolithic periods to some degree. The major advance of Neolithic 1 was true farming, in the proto-Neolithic Natufian cultures, wild cereals were harvested, and perhaps early seed selection and re-seeding occurred. The grain was ground into flour, emmer wheat was domesticated, and animals were herded and domesticated

Pyrenees
–
The Pyrenees is a range of mountains in southwest Europe that forms a natural border between France and Spain. For the most part, the main crest forms a divide between France and Spain, with the microstate of Andorra sandwiched in between. The Crown of Aragon and the Kingdom of Navarre have historically extended on both sides of the range, with smaller northern portions now in France and larger southern parts now in Spain. The demonym for the noun Pyrenees in English is Pyrenean, in Greek mythology, Pyrene is a princess who gave her name to the Pyrenees. The Greek historian Herodotus says Pyrene is the name of a town in Celtic Europe, Hercules, characteristically drunk and lustful, violates the sacred code of hospitality and rapes his hosts daughter. Pyrene gives birth to a serpent and runs away to the woods, alone, she pours out her story to the trees, attracting the attention of wild beasts who tear her to pieces. After his victory over Geryon, Hercules passes through the kingdom of Bebryx again, and all the rock-cliffs and wild-beast haunts echo back Pyrene. … The mountains hold on to the name through the ages. Pliny the Elder connects the story of Hercules and Pyrene to Lusitania, the Spanish Pyrenees are part of the following provinces, from east to west, Girona, Barcelona, Lleida, Huesca, Navarra and Gipuzkoa. The French Pyrenees are part of the following départements, from east to west, Pyrénées-Orientales, Aude, Ariège, Haute-Garonne, Hautes-Pyrénées, the independent principality of Andorra is sandwiched in the eastern portion of the mountain range between the Spanish Pyrenees and French Pyrenees. Physiographically, the Pyrenees may be divided into three sections, the Atlantic, the Central, and the Eastern Pyrenees, together, they form a distinct physiographic province of the larger Alpine System division. In the Western Pyrenees, from the Basque mountains near the Bay of Biscay of the Atlantic Ocean, at the eastern end on the southern side lies a distinct area known as the Sub-Pyrenees. On the French side the slopes of the range descend abruptly. The Pyrenees are older than the Alps, their sediments were first deposited in coastal basins during the Paleozoic and Mesozoic eras, the intense pressure and uplifting of the Earths crust first affected the eastern part and moved progressively to the entire chain, culminating in the Eocene Epoch. The eastern part of the Pyrenees consists largely of granite and gneissose rocks, the massive and unworn character of the chain comes from its abundance of granite, which is particularly resistant to erosion, as well as weak glacial development. Low passes are lacking, and the roads and the railroads between France and Spain run only in the lowlands at the western and eastern ends of the Pyrenees. A notable visual feature of mountain range is La Brèche de Roland, a gap in the ridge line. Coal deposits capable of being profitably worked are situated chiefly on the Spanish slopes, the open pit of Trimoun close to the commune of Luzenac is one of the greatest sources of talc in Europe

Roca dels Moros
–
The Roca dels Moros or Caves of El Cogul is a rock shelter containing paintings of prehistoric Levantine rock art. The site is in El Cogul, in the community of Catalonia. Since 1998 the paintings have been protected as part of a UNESCO World Heritage Site, inscriptions in Northeastern Iberian script and in Latin alphabet indicate that the place was used as a sanctuary into Iberian and Roman times. The Caves of El Cogul are a shelter in El Cogul in the autonomous community of Catalonia. In 1908 paintings of prehistoric Levantine rock art were discovered by the rector, Ramon Huguet. The first prehistorians to study the paintings, such as Henri Breuil and Juan Cabré, there is now a consensus that the paintings are post-palaeolithic, although uncertainty persists as to their date. Since 1998 the paintings have been protected as part of a UNESCO World Heritage Site, near the paintings is a cemetery with tombs carved into the rock. Inscriptions in Northeastern Iberian script and in Latin alphabet, one of which is an ex-voto, at Roca dels Moros there are forty-five figures depicted, of which thirty-eight are painted bright red, black and dark red, seven are engraved in stone. A dance scene is the most famous of the paintings, Nine women are depicted, some are painted in black and others in red. They dancie around a male figure at the center with an abnormally large phallus. Along with humans, there are several animals, conservation work has been carried out on the paintings under the auspices of the Museu dArqueologia de Catalunya.

Paleolithic
–
It extends from the earliest known use of stone tools, probably by Homo habilis initially,2.6 million years ago, to the end of the Pleistocene around 10,000 BP. The Paleolithic era is followed by the Mesolithic, the date of the Paleolithic–Mesolithic boundary may vary by locality as much as several thousand years. During the Paleolithic period, humans grouped together in small societies such as bands, the Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers, however, due to their nature, surviving artifacts of the Paleolithic era are known as paleoliths. About 50,000 years ago, there was a increase in the diversity of artifacts. For the first time in Africa, bone artifacts and the first art appear in the archaeological record, the first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. The new technology generated an explosion of modern humans which is believed to have led to the extinction of the Neanderthals. Humankind gradually evolved from members of the genus Homo—such as Homo habilis. The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures, by c. 50,000 – c. 40,000 BP, the first humans set foot in Australia. By c. 45,000 BP, humans lived at 61°N latitude in Europe, by c. 30,000 BP, Japan was reached, and by c. 27,000 BP humans were present in Siberia, above the Arctic Circle. At the end of the Upper Paleolithic, a group of humans crossed Beringia, the term Paleolithic was coined by archaeologist John Lubbock in 1865. It derives from Greek, παλαιός, palaios, old, and λίθος, lithos, stone, human evolution is the part of biological evolution concerning the emergence of anatomically modern humans as a distinct species. The Paleolithic Period coincides almost exactly with the Pleistocene epoch of geologic time and this epoch experienced important geographic and climatic changes that affected human societies. During the preceding Pliocene, continents had continued to drift from possibly as far as 250 km from their present locations to positions only 70 km from their current location. South America became linked to North America through the Isthmus of Panama, most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas. Africas collision with Asia created the Mediterranean Sea, cutting off the remnants of the Tethys Ocean, climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. The formation of an Arctic ice cap around 3 million years ago is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation probably began before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas

Charcoal
–
Charcoal is a lightweight, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis- the heating of wood or other substances in the absence of oxygen, the whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, the success of the operation depends upon the rate of the combustion. The operation is so delicate that it was left to colliers. They often lived alone in small huts in order to tend their wood piles, for example, in the Harz Mountains of Germany, charcoal burners lived in conical huts called Köten which are still much in evidence today. The massive production of charcoal was a cause of deforestation. The increasing scarcity of easily harvested wood was a factor behind the switch to fossil fuel equivalents, mainly coal. Charcoal made at 300 °C is brown, soft and friable, and readily inflames at 380 °C, made at higher temperatures it is hard and brittle, in Finland and Scandinavia, the charcoal was considered the by-product of wood tar production. The best tar came from pine, thus pinewoods were cut down for tar pyrolysis, the residual charcoal was widely used as substitute for metallurgical coke in blast furnaces for smelting. Tar production led to deforestation, it has been estimated all Finnish forests are younger than 300 years. The end of tar production at the end of the 19th century resulted in rapid re-forestation, the charcoal briquette was first invented and patented by Ellsworth B. A. Zwoyer of Pennsylvania in 1897 and was produced by the Zwoyer Fuel Company. The process was popularized by Henry Ford, who used wood. Ford Charcoal went on to become the Kingsford Company, Charcoal has been made by various methods. The traditional method in Britain used a clamp and this is essentially a pile of wooden logs leaning against a chimney. The chimney consists of 4 wooden stakes held up by some rope, the logs are completely covered with soil and straw allowing no air to enter. It must be lit by introducing some burning fuel into the chimney, if the soil covering gets torn by the fire, additional soil is placed on the cracks. Once the burn is complete, the chimney is plugged to prevent air from entering, the true art of this production method is in managing the sufficient generation of heat, and its transfer to wood parts in the process of being carbonised. A strong disadvantage of this method is the huge amount of emissions that are harmful to human health
