Ronse ( Dutch: [ˈrɔnsə] ; French: Renaix [ʁənɛ] ) is a Belgian city and a municipality in the Flemish province of East Flanders . The municipality only encompasses the city of Ronse proper.
101-564: The hills around Ronse show clues of human activity in the Paleolithic period. In the Neolithic , the area was populated with settled farmers and cattle breeders. Assorted fragments of building structures also attest of settlements in the area during Roman times. Ronse's urban center took shape in the 7th century, when Saint Amand – or one of his successors – built a church and monastery in honour of Saint Peter and Saint Paul . In
202-549: A Romanesque -style crypt in 1083. The church of Saint Hermes, which was later built on top of the crypt, was consecrated in 1129. A pilgrimage in honour of the Saint, who had by then become known to cure mental illnesses, sustained the local economy. There is still a French saying today which translates as "Saint Hermes cures the area's madmen but keeps the Ronse dwellers as they are". The Lord of Ronse, Gerard de Wautripont, who
303-428: A nomadic lifestyle. In addition, even a large area of land could not support many people without being actively farmed - food was difficult to come by and so groups were prevented from growing too large by the amount of food they could gather. Like contemporary hunter-gatherers, Paleolithic humans enjoyed an abundance of leisure time unparalleled in both Neolithic farming societies and modern industrial societies. At
404-431: A conveyor. Power steering for automobiles uses hydraulic mechanisms, as does practically all earth moving equipment and other construction equipment and many attachments to tractors. Pneumatic (usually compressed air) power is widely used to operate industrial valves. By the early 20th century machines developed the ability to perform more complex operations that had previously been done by skilled craftsmen. An example
505-441: A gang of 20 to 40 men will require a financial compensation for their work at least equal to the required expended food calories (which is at least 4 to 20 times higher). In most situations, the worker will also want compensation for the lost time, which is easily 96 times greater per day. Even if we assume the real wage cost for the human labour to be at US $ 1.00/day, an energy cost is generated of about $ 4.00/kWh. Despite this being
606-694: A group of early humans, frequently called Homo heidelbergensis , came to Europe from Africa and eventually evolved into Homo neanderthalensis ( Neanderthals ). In the Middle Paleolithic, Neanderthals were present in the region now occupied by Poland. Both Homo erectus and Homo neanderthalensis became extinct by the start of the Upper Paleolithic. Descended from Homo sapiens , the anatomically modern Homo sapiens sapiens emerged in eastern Africa c. 300,000 BP, left Africa around 50,000 BP, and expanded throughout
707-793: A herd of animals at a waterhole so as to stun one of them. There are no indications of hafting , and some artifacts are far too large for that. Thus, a thrown hand axe would not usually have penetrated deeply enough to cause very serious injuries. Nevertheless, it could have been an effective weapon for defense against predators. Choppers and scrapers were likely used for skinning and butchering scavenged animals and sharp-ended sticks were often obtained for digging up edible roots. Presumably, early humans used wooden spears as early as 5 million years ago to hunt small animals, much as their relatives, chimpanzees , have been observed to do in Senegal , Africa. Lower Paleolithic humans constructed shelters, such as
808-413: A machine is defined as follows: Every machine is constructed for the purpose of performing certain mechanical operations, each of which supposes the existence of two other things besides the machine in question, namely, a moving power, and an object subject to the operation, which may be termed the work to be done. Machines, in fact, are interposed between the power and the work, for the purpose of adapting
909-505: A need to distribute resources such as food and meat equally to avoid famine and ensure a stable food supply. Raymond C. Kelly speculates that the relative peacefulness of Middle and Upper Paleolithic societies resulted from a low population density, cooperative relationships between groups such as reciprocal exchange of commodities and collaboration on hunting expeditions, and because the invention of projectile weapons such as throwing spears provided less incentive for war, because they increased
1010-540: A number of ways by modern archaeologists. The earliest explanation, by the prehistorian Abbe Breuil , interpreted the paintings as a form of magic designed to ensure a successful hunt. However, this hypothesis fails to explain the existence of animals such as saber-toothed cats and lions , which were not hunted for food, and the existence of half-human, half-animal beings in cave paintings. The anthropologist David Lewis-Williams has suggested that Paleolithic cave paintings were indications of shamanistic practices, because

Some argue that there was no formal leadership during the Middle and Upper Paleolithic. Like contemporary egalitarian hunter-gatherers such as the Mbuti pygmies, societies may have made decisions by communal consensus decision making rather than by appointing permanent rulers such as chiefs and monarchs . Nor

In 1840, within the newly created Kingdom of Belgium, more than 55% of the city's inhabitants derived a living from the textile industry. A few years later, however, increased mechanisation gave rise to a deep economic crisis . Many left Ronse to join the textile plants in Northern France ( Lille - Roubaix - Tourcoing ) or to take on agricultural work in
1313-485: A towed artillery unit is considered motorized while a self-propelled one is mechanized. When we compare the efficiency of a labourer, we see that he has an efficiency of about 1%–5.5% (depending on whether he uses arms, or a combination of arms and legs). Internal combustion engines mostly have an efficiency of about 20%, although large diesel engines , such as those used to power ships, may have efficiencies of nearly 50%. Industrial electric motors have efficiencies up to

Construction equipment includes cranes , concrete mixers , concrete pumps , cherry pickers and an assortment of power tools. Powered machinery today usually means either by electric motor or internal combustion engine. Before the first decade of the 20th century powered usually meant by steam engine, water or wind. Many of

Inside factories, warehouses, lumber yards and other manufacturing and distribution operations, material handling equipment replaced manual carrying or hand trucks and carts. In mining and excavation, power shovels replaced picks and shovels. Rock and ore crushing had been done for centuries by water-powered trip hammers , but trip hammers have been replaced by modern ore crushers and ball mills . Bulk material handling systems and equipment are used for

The minor excursion is a "stadial"; times between stadials are "interstadials". Each glacial advance tied up huge volumes of water in continental ice sheets 1,500–3,000 m (4,900–9,800 ft ) deep, resulting in temporary sea level drops of 100 m (330 ft) or more over

Other organic commodities were adapted for use as tools, including leather and vegetable fibers ; however, due to rapid decomposition, these have not survived to any great degree. About 50,000 years ago, a marked increase in the diversity of artifacts occurred. In Africa, bone artifacts and

Human societies from the Paleolithic to the early Neolithic farming tribes lived without states and organized governments. For most of
1919-543: Is no evidence of hominins in America, Australia, or almost anywhere in Oceania during this time period. Fates of these early colonists, and their relationships to modern humans, are still subject to debate. According to current archaeological and genetic models, there were at least two notable expansion events subsequent to peopling of Eurasia c. 2,000,000 – c. 1,500,000 BP. Around 500,000 BP
2020-808: Is the glass bottle making machine developed 1905. It replaced highly paid glass blowers and child labor helpers and led to the mass production of glass bottles. After 1900 factories were electrified , and electric motors and controls were used to perform more complicated mechanical operations. This resulted in mechanized processes to manufacture almost all goods. In manufacturing, mechanization replaced hand methods of making goods. Prime movers are devices that convert thermal, potential or kinetic energy into mechanical work. Prime movers include internal combustion engines, combustion turbines (jet engines), water wheels and turbines, windmills and wind turbines and steam engines and turbines. Powered transportation equipment such as locomotives, automobiles and trucks and airplanes,

Humans hunted wild animals for meat and gathered food, firewood, and materials for their tools, clothes, or shelters. The population density was very low, around only 0.4 inhabitants per square kilometre (1/sq mi). This was most likely due to low body fat, infanticide , high levels of physical activity among women, late weaning of infants, and

For the duration of the Paleolithic, human populations remained low, especially outside the equatorial region. The entire population of Europe between 16,000 and 11,000 BP likely averaged some 30,000 individuals, and between 40,000 and 16,000 BP, it
2323-722: The Arctic Circle . By the end of the Upper Paleolithic Age humans had crossed Beringia and expanded throughout the Americas continents. The term " Palaeolithic " was coined by archaeologist John Lubbock in 1865. It derives from Greek: παλαιός , palaios , "old"; and λίθος , lithos , "stone", meaning "old age of the stone" or "Old Stone Age ". The Paleolithic overlaps with the Pleistocene epoch of geologic time. Both ended 12,000 years ago although
2424-582: The Hadza people and the Aboriginal Australians suggest that the sexual division of labor in the Paleolithic was relatively flexible. Men may have participated in gathering plants, firewood and insects, and women may have procured small game animals for consumption and assisted men in driving herds of large game animals (such as woolly mammoths and deer) off cliffs. Additionally, recent research by anthropologist and archaeologist Steven Kuhn from
2525-510: The Isthmus of Panama , bringing a nearly complete end to South America's distinctive marsupial fauna. The formation of the isthmus had major consequences on global temperatures, because warm equatorial ocean currents were cut off, and the cold Arctic and Antarctic waters lowered temperatures in the now-isolated Atlantic Ocean. Most of Central America formed during the Pliocene to connect
2626-646: The Mousterian and the Aterian industries. Lower Paleolithic humans used a variety of stone tools, including hand axes and choppers. Although they appear to have used hand axes often, there is disagreement about their use. Interpretations range from cutting and chopping tools, to digging implements, to flaking cores, to the use in traps, and as a purely ritual significance, perhaps in courting behavior . William H. Calvin has suggested that some hand axes could have served as "killer frisbees " meant to be thrown at
2727-510: The Old Stone Age (from Ancient Greek παλαιός ( palaiós ) 'old' and λίθος ( líthos ) 'stone'), is a period in human prehistory that is distinguished by the original development of stone tools , and which represents almost the entire period of human prehistoric technology . It extends from the earliest known use of stone tools by hominins , c. 3.3 million years ago, to

It was completely replaced around 250,000 years ago by the more complex Acheulean industry, which was first conceived by Homo ergaster around 1.8–1.65 million years ago. The Acheulean implements completely vanish from the archaeological record around 100,000 years ago and were replaced by more complex Middle Paleolithic tool kits such as

The Upper Palaeolithic saw the emergence of boiling, an advance in food processing technology which rendered plant foods more digestible, decreased their toxicity, and maximised their nutritional value. Thermally altered rock (heated stones) are easily identifiable in the archaeological record. Stone-boiling and pit-baking were common techniques which involved heating large pebbles then transferring

During the late Upper Paleolithic (Latest Pleistocene) c. 18,000 BP, the Beringia land bridge between Asia and North America was blocked by ice, which may have prevented early Paleo-Indians such as the Clovis culture from directly crossing Beringia to reach the Americas. According to Mark Lynas (through collected data),
3636-571: The Lower Paleolithic ( c. 1.9 million years ago) or at the latest in the early Middle Paleolithic ( c. 250,000 years ago). Some scientists have hypothesized that hominins began cooking food to defrost frozen meat, which would help ensure their survival in cold regions. Archaeologists cite morphological shifts in cranial anatomy as evidence for emergence of cooking and food processing technologies. These morphological changes include decreases in molar and jaw size, thinner tooth enamel , and decrease in gut volume. During much of
3737-837: The Lower Paleolithic, human societies were possibly more hierarchical than their Middle and Upper Paleolithic descendants, and probably were not grouped into bands , though during the end of the Lower Paleolithic, the latest populations of the hominin Homo erectus may have begun living in small-scale (possibly egalitarian) bands similar to both Middle and Upper Paleolithic societies and modern hunter-gatherers. Middle Paleolithic societies, unlike Lower Paleolithic and early Neolithic ones, consisted of bands that ranged from 20–30 or 25–100 members and were usually nomadic. These bands were formed by several families. Bands sometimes joined together into larger "macrobands" for activities such as acquiring mates and celebrations or where resources were abundant. By
3838-563: The Mediterranean Sea, such as Coa de sa Multa ( c. 300,000 BP), has also indicated that both Middle and Upper Paleolithic humans used rafts to travel over large bodies of water (i.e. the Mediterranean Sea) for the purpose of colonizing other bodies of land. By around 200,000 BP, Middle Paleolithic stone tool manufacturing spawned a tool-making technique known as the prepared-core technique , which

Like in modern hunter-gatherer societies, individuals in Paleolithic societies may have been subordinate to the band as a whole. Both Neanderthals and modern humans took care of
4040-601: The Neanderthals hunted large game animals mostly by ambushing them and attacking them with handheld weapons such as thrusting spears rather than attacking them from a distance with projectiles. During the Upper Paleolithic , further inventions were made, such as the net ( c. 22,000 or c. 29,000 BP) bolas , the spear thrower ( c. 30,000 BP), the bow and arrow ( c. 25,000 or c. 30,000 BP) and

This ability allowed humans to become efficient hunters and to exploit a wide variety of game animals. Recent research indicates that the Neanderthals timed their hunts and the migrations of game animals long before the beginning of the Upper Paleolithic. The social organization of

4242-693: The Paleolithic Age went through 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
4343-531: The Pleistocene started 2.6 million years ago, 700,000 years after the Paleolithic's start. 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 (160 mi ) from their present locations to positions only 70 km (43 mi) from their current location. South America became linked to North America through
4444-533: The Pleistocene's overall climate could be characterized as a continuous El Niño with trade winds in the south Pacific weakening or heading east, warm air rising near Peru , warm water spreading from the west Pacific and the Indian Ocean to the east Pacific, and other El Niño markers. The Paleolithic is often held to finish at the end of the ice age (the end of the Pleistocene epoch), and Earth's climate became warmer. This may have caused or contributed to
4545-492: The University of Arizona is argued to support that this division of labor did not exist prior to the Upper Paleolithic and was invented relatively recently in human pre-history. Sexual division of labor may have been developed to allow humans to acquire food and other resources more efficiently. Possibly there was approximate parity between men and women during the Middle and Upper Paleolithic, and that period may have been
4646-410: The adoption of agriculture because women in farming societies typically have more pregnancies and are expected to do more demanding work than women in hunter-gatherer societies. Like most modern hunter-gatherer societies, Paleolithic and Mesolithic groups probably followed a largely ambilineal approach. At the same time, depending on the society, the residence could be virilocal, uxorilocal, and sometimes
4747-479: The beginning of the period. Climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. Ice sheets grew on Antarctica . The formation of an Arctic ice cap around 3 million years ago is signaled by an abrupt shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic and North Pacific Ocean beds. Mid-latitude glaciation probably began before

It is during that period that one of the most beautiful castles of the Southern Netherlands (demolished in 1823) was built for Count Jean de Nassau-Siegen , baron of Ronse since 1629, the castle of Ronse . The plague in 1635–1636 nearly emptied
4949-494: The city. Despite opposition by the King of Spain , Ronse was annexed to France from 1680 to 1700. During the following Austrian period, on March 31, 1719, a gigantic fire again turned most of the city to ashes. Thanks to the perseverance of its inhabitants, Ronse could again rank as a city, with its commerce and businesses still based on the textile industry. The Fleurus Victory , on June 26, 1794, allowed France to occupy and annex
5050-679: The city. It quickly recovered, however, thanks to its booming economy based on the fabrication and preparation of linen. Around the middle of the 16th century, the city became an important Calvinist center in the Spanish Netherlands . The religious troubles of that century, especially the terrible repression of the Duke of Alba , forced a large number of the city's weavers and fullers to find permanent refuge in Holland , England, and Germany. The fire of July 21, 1559 completely ruined
5151-488: The combined work capability of a human is also much lower than that of a machine. An average human worker can provide work good for around 0,9 hp (2.3 MJ per hour) while a machine (depending on the type and size) can provide for far greater amounts of work. For example, it takes more than one and a half hour of hard labour to deliver only one kWh – which a small engine could deliver in less than one hour while burning less than one litre of petroleum fuel. This implies that

French legislation was applied from this point on, until Belgium merged with the Netherlands in 1815. In 1798, the so-called "farmers' war", a reaction to the military conscription imposed by France, cost many lives. In 1799, Ronse counted about 10,000 inhabitants but

However, other sources claim that most Paleolithic groups may have been larger, more complex, sedentary and warlike than most contemporary hunter-gatherer societies, due to occupying more resource-abundant areas than most modern hunter-gatherers who have been pushed into more marginal habitats by agricultural societies. Anthropologists have typically assumed that in Paleolithic societies, women were responsible for gathering wild plants and firewood, and men were responsible for hunting and scavenging dead animals. However, analogies to existent hunter-gatherer societies such as
5555-555: The earliest Paleolithic ( Lower Paleolithic ) societies remains largely unknown to scientists, though Lower Paleolithic hominins such as Homo habilis and Homo erectus are likely to have had more complex social structures than chimpanzee societies. Late Oldowan/Early Acheulean humans such as Homo ergaster / Homo erectus may have been the first people to invent central campsites or home bases and incorporate them into their foraging and hunting strategies like contemporary hunter-gatherers, possibly as early as 1.7 million years ago; however,
5656-543: The earliest solid evidence for the existence of home bases or central campsites (hearths and shelters) among humans only dates back to 500,000 years ago. Similarly, scientists disagree whether Lower Paleolithic humans were largely monogamous or polygynous . In particular, the Provisional model suggests that bipedalism arose in pre-Paleolithic australopithecine societies as an adaptation to monogamous lifestyles; however, other researchers note that sexual dimorphism

Some sources claim that most Middle and Upper Paleolithic societies were possibly fundamentally egalitarian and may have rarely or never engaged in organized violence between groups (i.e. war). Some Upper Paleolithic societies in resource-rich environments (such as societies in Sungir , in what is now Russia) may have had more complex and hierarchical organization (such as tribes with

The Paleolithic Age in Europe preceded the Mesolithic Age , although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age
6060-480: The end of the Paleolithic era ( c. 10,000 BP), people began to settle down into permanent locations, and began to rely on agriculture for sustenance in many locations. Much evidence exists that humans took part in long-distance trade between bands for rare commodities (such as ochre , which was often used for religious purposes such as ritual ) and raw materials, as early as 120,000 years ago in Middle Paleolithic. Inter-band trade may have appeared during
6161-794: The end of the Paleolithic, specifically the Middle or Upper Paleolithic, people began to produce works of art such as cave paintings , rock art and jewellery and began to engage in religious behavior such as burials and rituals. At the beginning of the Paleolithic, hominins were found primarily in eastern Africa, east of the Great Rift Valley . Most known hominin fossils dating earlier than one million years before present are found in this area, particularly in Kenya , Tanzania , and Ethiopia . By c. 2,000,000 – c. 1,500,000 BP, groups of hominins began leaving Africa, settling southern Europe and Asia. The South Caucasus

#17327764662476262-680: The end of the Pleistocene caused the mammoths' habitat to shrink, resulting in a drop in population. The small populations were then hunted out by Paleolithic humans. The global warming that occurred during the end of the Pleistocene and the beginning of the Holocene may have made it easier for humans to reach mammoth habitats that were previously frozen and inaccessible. Small populations of woolly mammoths survived on isolated Arctic islands, Saint Paul Island and Wrangel Island , until c. 3700 BP and c. 1700 BP respectively. The Wrangel Island population became extinct around
6363-430: 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 . The Pleistocene climate was characterized by repeated glacial cycles during which continental glaciers pushed to the 40th parallel in some places. Four major glacial events have been identified, as well as many minor intervening events. A major event

The effects of glaciation were global. Antarctica was ice-bound throughout the Pleistocene and the preceding Pliocene. The Andes were covered in the south by the Patagonian ice cap. There were glaciers in New Zealand and Tasmania . The decaying glaciers of Mount Kenya , Mount Kilimanjaro , and
6565-403: The extinction of the Pleistocene megafauna , although it is also possible that the late Pleistocene extinctions were (at least in part) caused by other factors such as disease and overhunting by humans. New research suggests that the extinction of the woolly mammoth may have been caused by the combined effect of climatic change and human hunting. Scientists suggest that climate change during

Archaeologists classify artifacts of the last 50,000 years into many different categories, such as projectile points , engraving tools, sharp knife blades, and drilling and piercing tools. Humankind gradually evolved from early members of
6868-530: The first mechanical devices used in agriculture was the seed drill invented by Jethro Tull around 1700. The seed drill allowed more uniform spacing of seed and planting depth than hand methods, increasing yields and saving valuable seed. In 1817, the first bicycle was invented and used in Germany. Mechanized agriculture greatly increased in the late eighteenth and early nineteenth centuries with horse drawn reapers and horse powered threshing machines . By

Excavations in Gona, Ethiopia , have produced thousands of artifacts, and through radioisotopic dating and magnetostratigraphy the sites can be firmly dated to 2.6 million years ago. Evidence shows these early hominins intentionally selected raw stone with good flaking qualities and chose appropriately sized stones for their needs to produce sharp-edged tools for cutting. The earliest Paleolithic stone tool industry,

The Lower Paleolithic Homo erectus possibly invented rafts ( c. 840,000 – c. 800,000 BP) to travel over large bodies of water, which may have allowed a group of Homo erectus to reach the island of Flores and evolve into
7272-634: The invention of these devices brought fish into the human diets, which provided a hedge against starvation and a more abundant food supply. Thanks to their technology and their advanced social structures, Paleolithic groups such as the Neanderthals—who had a Middle Paleolithic level of technology—appear to have hunted large game just as well as Upper Paleolithic modern humans, and the Neanderthals in particular may have likewise hunted with projectile weapons. Nonetheless, Neanderthal use of projectile weapons in hunting occurred very rarely (or perhaps never) and
7373-434: The lack of control of fire: studies of cave settlements in Europe indicate no regular use of fire prior to c. 400,000 – c. 300,000 BP. East Asian fossils from this period are typically placed in the genus Homo erectus . Very little fossil evidence is available at known Lower Paleolithic sites in Europe, but it is believed that hominins who inhabited these sites were likewise Homo erectus . There
7474-581: The late Middle Paleolithic around 100,000 BP or perhaps even earlier. Archaeological evidence from the Dordogne region of France demonstrates that members of the European early Upper Paleolithic culture known as the Aurignacian used calendars ( c. 30,000 BP). This was a lunar calendar that was used to document the phases of the moon. Genuine solar calendars did not appear until
7575-647: The late nineteenth century steam power was applied to threshing and steam tractors appeared. Internal combustion began being used for tractors in the early twentieth century. Threshing and harvesting was originally done with attachments for tractors, but in the 1930s independently powered combine harvesters were in use. In the mid to late 19th century, hydraulic and pneumatic devices were able to power various mechanical actions, such as positioning tools or work pieces. Pile drivers and steam hammers are examples for heavy work. In food processing, pneumatic or hydraulic devices could start and stop filling of cans or bottles on
7676-425: The low 90% range, before correcting for the conversion efficiency of fuel to electricity of about 35%. When we compare the costs of using an internal combustion engine to a worker to perform work, we notice that an engine can perform more work at a comparative cost. 1 liter of fossil fuel burnt with an IC engine equals about 50 hands of workers operating for 24 hours or 275 arms and legs for 24 hours. In addition,
7777-437: The main themes in the paintings and other artifacts (powerful beasts, risky hunting scenes and the over-sexual representation of women) are to be expected in the fantasies of adolescent males during the Upper Paleolithic. Mechanisation Mechanization (or mechanisation ) is the process of changing from working largely or exclusively by hand or with animals to doing that work with machinery. In an early engineering text,
7878-513: The mathematical development of gear designs. Clocks were some of the earliest mass-produced items, beginning around 1830. Water-powered bellows for blast furnaces, used in China in ancient times, were in use in Europe by the 15th century. De re Metallica contains drawings related to bellows for blast furnaces including a fabrication drawing. Improved gear designs decreased wear and increased efficiency. Mathematical gear designs were developed in
7979-407: The mid 17th century. French mathematician and engineer Desargues designed and constructed the first mill with epicycloidal teeth ca. 1650. In the 18th century involute gears , another mathematical derived design, came into use. Involute gears are better for meshing gears of different sizes than epicycloidal. Gear cutting machines came into use in the 18th century. The Newcomen steam engine
8080-421: The mid-1800s. After the early decades of the 19th century, iron increasingly replaced wood in gearing and shafts in textile machinery. In the 1840s self acting machine tools were developed. Machinery was developed to make nails ca. 1810. The Fourdrinier paper machine for continuous production of paper was patented in 1801, displacing the centuries-old hand method of making individual sheets of paper. One of
8181-415: The most gender-equal time in human history. Archaeological evidence from art and funerary rituals indicates that a number of individual women enjoyed seemingly high status in their communities, and it is likely that both sexes participated in decision making. The earliest known Paleolithic shaman ( c. 30,000 BP) was female. Jared Diamond suggests that the status of women declined with
8282-620: The oldest example of ceramic art, the Venus of Dolní Věstonice ( c. 29,000 – c. 25,000 BP). Kilu Cave at Buku island , Solomon Islands , demonstrates navigation of some 60 km of open ocean at 30,000 BCcal. Early dogs were domesticated sometime between 30,000 and 14,000 BP, presumably to aid in hunting. However, the earliest instances of successful domestication of dogs may be much more ancient than this. Evidence from canine DNA collected by Robert K. Wayne suggests that dogs may have been first domesticated in
8383-548: The one to the other. In every fields, mechanization includes the use of hand tools. In modern usage, such as in engineering or economics, mechanization implies machinery more complex than hand tools and would not include simple devices such as an ungeared horse or donkey mill. Devices that cause speed changes or changes to or from reciprocating to rotary motion, using means such as gears , pulleys or sheaves and belts, shafts , cams and cranks , usually are considered machines. After electrification , when most small machinery
8484-471: The paintings of half-human, half-animal figures and the remoteness of the caves are reminiscent of modern hunter-gatherer shamanistic practices. Symbol-like images are more common in Paleolithic cave paintings than are depictions of animals or humans, and unique symbolic patterns might have been trademarks that represent different Upper Paleolithic ethnic groups. Venus figurines have evoked similar controversy. Archaeologists and anthropologists have described
8585-695: The pigment ochre from late Lower Paleolithic Acheulean archaeological sites suggests that Acheulean societies, like later Upper Paleolithic societies, collected and used ochre to create rock art. Nevertheless, it is also possible that the ochre traces found at Lower Paleolithic sites is naturally occurring. Upper Paleolithic humans produced works of art such as cave paintings, Venus figurines, animal carvings, and rock paintings. Upper Paleolithic art can be divided into two broad categories: figurative art such as cave paintings that clearly depicts animals (or more rarely humans); and nonfigurative, which consists of shapes and symbols. Cave paintings have been interpreted in
8686-486: The planet. Multiple hominid groups coexisted for some time in certain locations. Homo neanderthalensis were still found in parts of Eurasia c. 40,000 BP years, and engaged in an unknown degree of interbreeding with Homo sapiens sapiens . DNA studies also suggest an unknown degree of interbreeding between Homo sapiens sapiens and Homo sapiens denisova . Hominin fossils not belonging either to Homo neanderthalensis or to Homo sapiens species, found in
8787-647: The possible wood hut at Terra Amata . Fire was used by the Lower Paleolithic hominins Homo erectus and Homo ergaster as early as 300,000 to 1.5 million years ago and possibly even earlier by the early Lower Paleolithic (Oldowan) hominin Homo habilis or by robust Australopithecines such as Paranthropus . However, the use of fire only became common in the societies of the following Middle Stone Age and Middle Paleolithic . Use of fire reduced mortality rates and provided protection against predators. Early hominins may have begun to cook their food as early as
8888-408: The same time the island was settled by prehistoric humans. There is no evidence of prehistoric human presence on Saint Paul island (though early human settlements dating as far back as 6500 BP were found on the nearby Aleutian Islands ). Nearly all of our knowledge of Paleolithic people and way of life comes from archaeology and ethnographic comparisons to modern hunter-gatherer cultures such as
8989-423: The small hominin Homo floresiensis . However, this hypothesis is disputed within the anthropological community. The possible use of rafts during the Lower Paleolithic may indicate that Lower Paleolithic hominins such as Homo erectus were more advanced than previously believed, and may have even spoken an early form of modern language. Supplementary evidence from Neanderthal and modern human sites located around
9090-481: The spouses could live with neither the husband's relatives nor the wife's relatives at all. Taken together, most likely, the lifestyle of hunter-gatherers can be characterized as multilocal. Early examples of artistic expression, such as the Venus of Tan-Tan and the patterns found on elephant bones from Bilzingsleben in Thuringia , may have been produced by Acheulean tool users such as Homo erectus prior to
9191-754: The start of the Middle Paleolithic period. However, the earliest undisputed evidence of art during the Paleolithic comes from Middle Paleolithic / Middle Stone Age sites such as Blombos Cave –South Africa–in the form of bracelets , beads , rock art , and ochre used as body paint and perhaps in ritual. Undisputed evidence of art only becomes common in the Upper Paleolithic. Lower Paleolithic Acheulean tool users, according to Robert G. Bednarik, began to engage in symbolic behavior such as art around 850,000 BP. They decorated themselves with beads and collected exotic stones for aesthetic, rather than utilitarian qualities. According to him, traces of
9292-422: The tools themselves that allowed access to a wider variety and amount of food sources. For example, microliths or small stone tools or points were invented around 70,000–65,000 BP and were essential to the invention of bows and atlatls (spear throwers) in the following Upper Paleolithic. Harpoons were invented and used for the first time during the late Middle Paleolithic ( c. 90,000 BP);
9393-778: Was also in charge of the Inde Monastery at that time, gave the town all the privileges of a city in 1240. A few years later, the economy was flourishing and the Inde Monastery sold all its Ronse-based possessions. Until the French Revolution , the Ronse seigneury – a barony as of 1549 – included an enclave , the Ronse Franchise , which was administered by the Chapter of Saint Hermes with complete juridical and fiscal independence and its own justice system. On March 26, 1478, French troops pillaged and burned
9494-792: Was especially important for machine tools . A step beyond mechanization is automation . Early production machinery, such as the glass bottle blowing machine (ca. 1890s), required a lot of operator involvement. By the 1920s fully automatic machines, which required much less operator attention, were being used. The term is also used in the military to refer to the use of tracked armoured vehicles , particularly armoured personnel carriers , to move troops ( mechanized infantry ) that would otherwise have marched or ridden trucks into combat. In military terminology, mechanized refers to ground units that can fight from vehicles, while motorized refers to units ( motorized infantry ) that are transported and go to battle in unarmoured vehicles such as trucks. Thus,
9595-523: Was even lower at 4,000–6,000 individuals. However, remains of thousands of butchered animals and tools made by Palaeolithic humans were found in Lapa do Picareiro , a cave in Portugal , dating back between 41,000 and 38,000 years ago. Some researchers have noted that science, limited in that age to some early ideas about astronomy (or cosmology ), had limited impact on Paleolithic technology. Making fire
9696-409: Was first used, to pump water from a mine, in 1712. John Smeaton introduced metal gears and axles to water wheels in the mid to last half of the 18th century. The Industrial Revolution started mainly with textile machinery, such as the spinning jenny (1764) and water frame (1768). Demand for metal parts used in textile machinery led to the invention of many machine tools in the late 1700s until
9797-429: Was more elaborate than previous Acheulean techniques. This technique increased efficiency by allowing the creation of more controlled and consistent flakes . It allowed Middle Paleolithic humans to create stone-tipped spears , which were the earliest composite tools, by hafting sharp pointy stone flakes onto wooden shafts. In addition to improving tool-making methods, the Middle Paleolithic also saw an improvement of
9898-567: Was no longer hand powered, mechanization was synonymous with motorized machines. Extension of mechanization of the production process is termed as automation and it is controlled by a closed loop system in which feedback is provided by the sensors. In an automated machine the work of different mechanisms is performed automatically. Water wheels date to the Roman period and were used to grind grain and lift irrigation water. Water-powered bellows were in use on blast furnaces in China in 31 AD. By
9999-402: Was occupied by c. 1,700,000 BP, and northern China was reached by c. 1,660,000 BP. By the end of the Lower Paleolithic, members of the hominin family were living in what is now China, western Indonesia, and, in Europe, around the Mediterranean and as far north as England, France, southern Germany, and Bulgaria. Their further northward expansion may have been limited by
10100-459: Was there a formal division of labor during the Paleolithic. Each member of the group was skilled at all tasks essential to survival, regardless of individual abilities. Theories to explain the apparent egalitarianism have arisen, notably the Marxist concept of primitive communism . Christopher Boehm (1999) has hypothesized that egalitarianism may have evolved in Paleolithic societies because of
10201-433: Was widespread knowledge, and it was possible without an understanding of chemical processes, These types of practical skills are sometimes called crafts. Religion, superstitution or appeals to the supernatural may have played a part in the cultural explanations of phenomena like combustion . Paleolithic humans made tools of stone, bone (primarily of deer), and wood. The early paleolithic hominins, Australopithecus , were
