Loupe
–
A loupe is a simple, small magnification device used to see small details more closely. Loupes are also called hand lenses, three basic types of loupes exist, Simple lenses, generally used for low-magnification designs because of high optical aberration. Compound lenses, generally used for higher magnifications to control optical aberration, loupes are used in a number of industries, notably the jewelry trade, watchmaking, photography, printing, dentistry, education and ophthalmology. Loupes are also used in academia and life sciences, such as geology and biology, amateur naturalists may also find a hand lens or a loupe a useful tool when looking at or identifying species. They are also used in numismatics and stamp collecting, jewelers typically use a monocular, handheld loupe in order to magnify gemstones and other jewelry that they wish to inspect. A 10× magnification is good to use for inspecting jewelry and hallmarks and is the Gemological Institute of Americas standard for grading diamond clarity. Stones will sometimes be inspected at higher magnifications than 10×, although the depth of field, the accepted standard for grading diamonds is therefore that inclusions and blemishes visible at 10× impact the clarity grade. Loupes are employed to assist watchmakers in assembling mechanical watches, typical magnifications for viewing slides full-frame depend on image format,35 mm frames are best viewn at ca. 5×, while ca. 3× is optimal for viewing medium format slides, often, a 10× loupe is used to examine critical sharpness. Photographers using large format cameras use a loupe to view the ground glass image to aid in focusing. DSLR camera users also use loupes to help to identify dust and other particles on the sensor, offset and flexographic printing see frequent use of loupes in order to carefully analyze how ink lies on paper. Strippers use loupes in order to register film separations to one another, pressmen use them to check registration of colors, estimate dot-gain, and diagnose issues with roller pressure and chemistry based on the shape of individual dots and rosettes. Dental loupes aid dentists, hygienists, and dental therapists to devise accurate diagnose of oral conditions, additionally, loupes can improve dentists posture which can decrease occupational strain. Dental caries, also known as cavities, are most accurately identified by visual and tactile examination of a clean, magnification enables dentists to improve their ability to differentiate between a stain and a cavity. Cavities are rated and scored based on their visual presentation, if magnification is too high diagnosis becomes difficult due to the small field of view. Ideal magnification for diagnostic purposes is up to 2×, treatment of dental caries, periodontal disease, and pulpal disease are aided by magnification. The dental specialty of endodontics has performed the vast majority of research regarding magnification in dentistry, treatment of periodontal disease is achieved by removing calculus deposits, plaque and therefore bacteria which causes inflammation and subsequently bone destruction. In severe cases, surgery to reduce pocket depth is indicated, periodontists and hygienists must visualize plaque and calculus to remove it

Artisan
–
Artisans practice a craft and may through experience and aptitude reach the expressive levels of an artist. The adjective artisanal is sometimes used in describing hand-processing in what is viewed as an industrial process. Thus, artisanal is sometimes used in marketing and advertising as a word to describe or imply some relation with the crafting of handmade food products, such as bread. Many of these have traditionally been handmade, rural or pastoral goods but are now commonly made on a larger scale with automated mechanization in factories. Artisans were the dominant producers of products prior to the Industrial Revolution. In ancient Greece, artisans were drawn to agoras and often built workshops nearby, during the Middle Ages, the term artisan was applied to those who made things or provided services. It did not apply to unskilled manual labourers, Artisans were divided into two distinct groups, those who operated their own businesses and those who did not. Those who owned their businesses were called masters, while the latter were the journeymen, one misunderstanding many people have about this social group is that they picture them as workers in the modern sense, employed by someone. The most influential group among the artisans were the masters, the business owners, the owners enjoyed a higher social status in their communities. Shokunin is a Japanese word for artisan or craftsman, which implies a pride in ones own work. In the words of shokunin Tashio Odate, Shokunin means not only having technical skill, a social obligation to work his best for the general welfare of the people, obligation both material and spiritual.

Watch
–
A watch is a small timepiece intended to be carried or worn by a person. It is designed to keep working despite the motions caused by the persons activities, a wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet. A pocket watch is designed for a person to carry in a pocket, watches evolved in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a device, driven by clockwork, powered by winding a mainspring. In the 1960s the electronic quartz watch was invented, which was powered by a battery, by the 1980s the quartz watch had taken over most of the market from the mechanical watch. Today most inexpensive and medium-priced watches, used mainly for timekeeping, have quartz movements, various extra features, called complications, such as moon-phase displays and the different types of tourbillon, are sometimes included. Modern watches often display the day, date, month and year, time-related features such as timers, chronographs and alarm functions are common. Some modern designs incorporate calculators, GPS and Bluetooth technology or have heart-rate monitoring capabilities, some watches use radio clock technology to regularly correct the time. Developments in the 2010s include smartwatches, which are elaborate computer-like electronic devices designed to be worn on a wrist and they generally incorporate timekeeping functions, but these are only small fractions of what the smartwatch can do. The study of timekeeping is known as horology, watches evolved from portable spring-driven clocks, which first appeared in 15th century Europe. Watches werent widely worn in pockets until the 17th century, one account says that the word watch came from the Old English word woecce which meant watchman, because it was used by town watchmen to keep track of their shifts at work. Another says that the term came from 17th century sailors, who used the new mechanisms to time the length of their shipboard watches, the increased accuracy of the balance wheel focused attention on errors caused by other parts of the movement, igniting a two-century wave of watchmaking innovation. The first thing to be improved was the escapement, the verge escapement was replaced in quality watches by the cylinder escapement, invented by Thomas Tompion in 1695 and further developed by George Graham in the 1720s. The British had predominated in watch manufacture for much of the 17th and 18th centuries, aaron Lufkin Dennison started a factory in 1851 in Massachusetts that used interchangeable parts, and by 1861 it was running a successful enterprise incorporated as the Waltham Watch Company. The concept of the wristwatch goes back to the production of the very earliest watches in the 16th century, elizabeth I of England received a wristwatch from Robert Dudley in 1571, described as an arm watch. The oldest surviving wristwatch is one made in 1806 and given to Joséphine de Beauharnais, from the beginning, wrist watches were almost exclusively worn by women, while men used pocket-watches up until the early 20th century. The Garstin Company of London patented a Watch Wristlet design in 1893, officers in the British Army began using wristwatches during colonial military campaigns in the 1880s, such as during the Anglo-Burma War of 1885. In continental Europe Girard-Perregaux and other Swiss watch makers began supplying German naval officers with wrist watches in about 1880 and these early models were essentially standard pocket-watches fitted to a leather strap but, by the early 20th century, manufacturers began producing purpose-built wristwatches

Clock
–
A clock is an instrument to measure, keep, and indicate time. The word clock is derived from the Celtic words clagan and clocca meaning bell, a silent instrument missing such a striking mechanism has traditionally been known as a timepiece. In general usage today a clock refers to any device for measuring and displaying the time, Watches and other timepieces that can be carried on ones person are often distinguished from clocks. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units, the day, the lunar month. Devices operating on several physical processes have been used over the millennia, a sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, an example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments, spring-driven clocks appeared during the 15th century. During the 15th and 16th centuries, clockmaking flourished, the next development in accuracy occurred after 1656 with the invention of the pendulum clock. A major stimulus to improving the accuracy and reliability of clocks was the importance of precise time-keeping for navigation, the electric clock was patented in 1840. The development of electronics in the 20th century led to clocks with no clockwork parts at all, the timekeeping element in every modern clock is a harmonic oscillator, a physical object that vibrates or oscillates at a particular frequency. This object can be a pendulum, a fork, a quartz crystal. Analog clocks usually indicate time using angles, Digital clocks display a numeric representation of time. Two numeric display formats are used on digital clocks, 24-hour notation. Most digital clocks use electronic mechanisms and LCD, LED, or VFD displays, for convenience, distance, telephony or blindness, auditory clocks present the time as sounds. There are also clocks for the blind that have displays that can be read by using the sense of touch, some of these are similar to normal analog displays, but are constructed so the hands can be felt without damaging them. The evolution of the technology of clocks continues today, the study of timekeeping is known as horology. The apparent position of the Sun in the sky moves over the course of a day, shadows cast by stationary objects move correspondingly, so their positions can be used to indicate the time of day. A sundial shows the time by displaying the position of a shadow on a flat surface, sundials can be horizontal, vertical, or in other orientations

Switzerland
–
Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The country is situated in western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km2. The establishment of the Old Swiss Confederacy dates to the medieval period, resulting from a series of military successes against Austria. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The country has a history of armed neutrality going back to the Reformation, it has not been in a state of war internationally since 1815, nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to international organisations. On the European level, it is a member of the European Free Trade Association. However, it participates in the Schengen Area and the European Single Market through bilateral treaties, spanning the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions, German, French, Italian and Romansh. Due to its diversity, Switzerland is known by a variety of native names, Schweiz, Suisse, Svizzera. On coins and stamps, Latin is used instead of the four living languages, Switzerland is one of the most developed countries in the world, with the highest nominal wealth per adult and the eighth-highest per capita gross domestic product according to the IMF. Zürich and Geneva have each been ranked among the top cities in the world in terms of quality of life, with the former ranked second globally, according to Mercer. The English name Switzerland is a compound containing Switzer, a term for the Swiss. The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, the Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for Confederates, Eidgenossen, used since the 14th century. The data code for Switzerland, CH, is derived from Latin Confoederatio Helvetica. The toponym Schwyz itself was first attested in 972, as Old High German Suittes, ultimately related to swedan ‘to burn’

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

Apprenticeship
–
An apprenticeship is a system of training a new generation of practitioners of a trade or profession with on-the-job training and often some accompanying study. Apprenticeship also enables practitioners to gain a license to practice in a regulated profession, Apprenticeships typically last 3 to 7 years. People who successfully complete an apprenticeship reach the journeyman or professional level of competence. In early modern usage, the clipped form prentice was common, the system of apprenticeship first developed in the later Middle Ages and came to be supervised by craft guilds and town governments. A master craftsman was entitled to employ young people as a form of labour in exchange for providing food, lodging. Most apprentices were males, but female apprentices were found in such as seamstress, tailor. Apprentices usually began at ten to fifteen years of age, in Coventry those completing seven-year apprenticeships with stuff merchants were entitled to become freemen of the city. Subsequently, governmental regulation and the licensing of technical colleges and vocational education formalized and bureaucratized the details of apprenticeship, Australian Apprenticeships encompass all apprenticeships and traineeships. They cover all sectors in Australia and are used to achieve both entry-level and career upskilling objectives. There were 470,000 Australian Apprentices in-training as at 31 March 2012, Australian Government employer and employee incentives may be applicable, while State and Territory Governments may provide public funding support for the training element of the initiative. Australian Apprenticeships combine time at work with formal training and can be full-time, part-time or school-based, Australian Apprentice and Traineeship services are dedicated to promoting retention, therefore much effort is made to match applicants with the right apprenticeship or traineeship. This is done with the aid of aptitude tests, tips, information and resources on potential apprenticeship and traineeship occupations are available in over sixty industries. The distinction between the terms apprentices and trainees lies mainly around traditional trades and the time it takes to gain a qualification, Australia also has a fairly unusual safety net in place for businesses and Australian Apprentices with its Group Training scheme. It is a safety net, because the Group Training Organisation is the employer and provides continuity of employment and it lasts two to four years – the duration varies among the 250 legally recognized apprenticeship trades. About 40 percent of all Austrian teenagers enter apprenticeship training upon completion of compulsory education and this number has been stable since the 1950s. The five most popular trades are, Retail Salesperson, Clerk, Car Mechanic, Hairdresser, there are many smaller trades with small numbers of apprentices, like EDV-Systemtechniker which is completed by fewer than 100 people a year. The Apprenticeship Leave Certificate provides the apprentice with access to two different vocational careers, the person responsible for overseeing the training inside the company is called Lehrherr or Ausbilder. An Ausbilder must prove he has the qualifications needed to educate another person

Guild
–
A guild /ɡɪld/ is an association of artisans or merchants who control the practice of their craft in a particular town. The earliest types of guild were formed as confraternities of tradesmen and they were organized in a manner something between a professional association, trade union, a cartel, and a secret society. A lasting legacy of traditional guilds are the guildhalls constructed and used as meeting places, an important result of the guild framework was the emergence of universities at Bologna, Oxford and Paris, they originated as guilds of students as at Bologna, or of masters as at Paris. Usually the founders were free independent master craftsmen who hired apprentices, there were several types of guilds, including the two main categories of merchant guilds and craft guilds but also the frith guild and religious guild. In many cases became the governing body of a town. The Freedom of the City, effective from the Middle Ages until 1835, gave the right to trade, Trade guilds arose in the 14th century as craftsmen united to protect their common interest. The occasion for these oaths were drunken banquets held on December 26, gregory of Tours tells a miraculous tale of a builder whose art and techniques suddenly left him, but were restored by an apparition of the Virgin Mary in a dream. Michel Rouche remarks that the story speaks for the importance of practically transmitted journeymanship, in France, guilds were called corps de métiers. According to Viktor Ivanovich Rutenburg, Within the guild itself there was little division of labour. Thus, according to Étienne Boileaus Book of Handicrafts, by the century there were no less than 100 guilds in Paris. In Catalan towns, specially at Barcelona, guilds or gremis were a basic agent in the society, a shoemakers guild is recorded in 1208. In England, specifically in the City of London Corporation, more than 110 guilds, referred to as companies, survive today. Other groups, such as the Worshipful Company of Tax Advisers, have been formed far more recently, membership in a livery company is expected for individuals participating in the governance of The City, as the Lord Mayor and the Remembrancer. The guild system reached a state in Germany circa 1300 and held on in German cities into the 19th century. In the 15th century, Hamburg had 100 guilds, Cologne 80, the latest guilds to develop in Western Europe were the gremios of Spain, e. g. Valencia or Toledo. Not all city economies were controlled by guilds, some cities were free, in order to become a Master, a Journeyman would have to go on a three-year voyage called Journeyman years. The practice of the Journeyman years still exists in Germany and France, in Ghent, as in Florence, the woolen textile industry developed as a congeries of specialized guilds. The appearance of the European guilds was tied to the emergent money economy, before this time it was not possible to run a money-driven organization, as commodity money was the normal way of doing business

Worshipful Company of Clockmakers
–
The Worshipful Company of Clockmakers is one of the Livery Companies of the City of London. The Clockmakers were formed by a Royal Charter in 1631, originally, no person was allowed to sell clocks unless they were a member of the Company. However, such requirements have since relaxed and later removed. The Company now exists as an institution, as do a majority of Livery Companies. The Company museum was housed in the London Guildhall Library. The collection includes John Harrisons clock H5, since 2015 the collection has been rehoused in the Science Museum in London. The new display was opened by HRH Princess Anne on 22nd October 2015. The Companys archive and library are still kept at the Guildhall Library. The Clockmakers Company ranks sixty-first in the order of precedence for Livery Companies and its motto is Tempus Rerum Imperator, Latin for Time is the commander of things. It is shown in the About Google Web Accelerator page, british Horological Institute Clockmakers Museum The Clockmakers Company

God
–
In monotheism, God is conceived of as the Supreme Being and principal object of faith. The concept of God as described by most theologians includes the attributes of omniscience, omnipotence, omnipresence, divine simplicity, many theologians also describe God as being omnibenevolent and all loving. Furthermore, some religions attribute only a purely grammatical gender to God, incorporeity and corporeity of God are related to conceptions of transcendence and immanence of God, with positions of synthesis such as the immanent transcendence of Chinese theology. God has been conceived as personal or impersonal. In theism, God is the creator and sustainer of the universe, while in deism, God is the creator, in pantheism, God is the universe itself. In atheism, God is not believed to exist, while God is deemed unknown or unknowable within the context of agnosticism, God has also been conceived as the source of all moral obligation, and the greatest conceivable existent. Many notable philosophers have developed arguments for and against the existence of God, there are many names for God, and different names are attached to different cultural ideas about Gods identity and attributes. In the ancient Egyptian era of Atenism, possibly the earliest recorded monotheistic religion, this deity was called Aten, premised on being the one true Supreme Being and creator of the universe. In the Hebrew Bible and Judaism, He Who Is, I Am that I Am, in the Christian doctrine of the Trinity, God, consubstantial in three persons, is called the Father, the Son, and the Holy Spirit. In Judaism, it is common to refer to God by the titular names Elohim or Adonai, in Islam, the name Allah is used, while Muslims also have a multitude of titular names for God. In Hinduism, Brahman is often considered a concept of God. In Chinese religion, God is conceived as the progenitor of the universe, intrinsic to it, other religions have names for God, for instance, Baha in the Baháí Faith, Waheguru in Sikhism, and Ahura Mazda in Zoroastrianism. The earliest written form of the Germanic word God comes from the 6th-century Christian Codex Argenteus, the English word itself is derived from the Proto-Germanic * ǥuđan. The reconstructed Proto-Indo-European form * ǵhu-tó-m was likely based on the root * ǵhau-, in the English language, the capitalized form of God continues to represent a distinction between monotheistic God and gods in polytheism. The same holds for Hebrew El, but in Judaism, God is also given a proper name, in many translations of the Bible, when the word LORD is in all capitals, it signifies that the word represents the tetragrammaton. Allāh is the Arabic term with no plural used by Muslims and Arabic speaking Christians and Jews meaning The God, Ahura Mazda is the name for God used in Zoroastrianism. Mazda, or rather the Avestan stem-form Mazdā-, nominative Mazdå and it is generally taken to be the proper name of the spirit, and like its Sanskrit cognate medhā, means intelligence or wisdom. Both the Avestan and Sanskrit words reflect Proto-Indo-Iranian *mazdhā-, from Proto-Indo-European mn̩sdʰeh1, literally meaning placing ones mind, Waheguru is a term most often used in Sikhism to refer to God

Richard Dawkins
–
Clinton Richard Dawkins FRS FRSL is an English ethologist, evolutionary biologist and author. He is a fellow of New College, Oxford, and was the University of Oxfords Professor for Public Understanding of Science from 1995 until 2008. Dawkins first came to prominence with his 1976 book The Selfish Gene, in 2006, he founded the Richard Dawkins Foundation for Reason and Science. Dawkins is an atheist, and is known for his criticism of creationism. In The Blind Watchmaker, he argues against the watchmaker analogy, instead, he describes evolutionary processes as analogous to a blind watchmaker in that reproduction, mutation, and selection are unguided by any designer. In The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and he opposes the teaching of creationism in schools. Dawkins was born in Nairobi, then in British Kenya, on 26 March 1941 and he is the son of Jean Mary Vyvyan and Clinton John Dawkins, who was an agricultural civil servant in the British Colonial Service in Nyasaland. His father was called up into the Kings African Rifles during World War II and returned to England in 1949 and his father had inherited a country estate, Over Norton Park in Oxfordshire, which he farmed commercially. Dawkins considers himself English and lives in Oxford, England, both his parents were interested in natural sciences, and they answered Dawkinss questions in scientific terms. Dawkins describes his childhood as a normal Anglican upbringing, and that left me with nothing. From 1954 to 1959 Dawkins attended Oundle School in Northamptonshire, an English public school with a distinct Church of England flavour, while at Oundle Dawkins read Bertrand Russells Why I Am Not a Christian for the first time. He studied zoology at Balliol College, Oxford, graduating in 1962, while there and he continued as a research student under Tinbergens supervision, receiving his MA and DPhil degrees by 1966, and remained a research assistant for another year. Tinbergen was a pioneer in the study of behaviour, particularly in the areas of instinct, learning and choice. From 1967 to 1969, he was an assistant professor of zoology at the University of California, during this period, the students and faculty at UC Berkeley were largely opposed to the ongoing Vietnam War, and Dawkins became involved in the anti-war demonstrations and activities. He returned to the University of Oxford in 1970 as a lecturer, in 1990, he became a reader in zoology. He held that professorship from 1995 until 2008, since 1970, he has been a fellow of New College, Oxford and he is now an emeritus fellow. In 1991, he gave the Royal Institution Christmas Lectures for Children on Growing Up in the Universe and he has also edited several journals, and has acted as editorial advisor to the Encarta Encyclopedia and the Encyclopedia of Evolution. He is listed as an editor and a columnist of the Council for Secular Humanisms Free Inquiry magazine

Evolution
–
Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of organisation, including the levels of species, individual organisms. In July 2016, scientists reported identifying a set of 355 genes from the LUCA of all living on Earth. The fossil record includes a progression from early biogenic graphite, to microbial mat fossils, existing patterns of biodiversity have been shaped both by speciation and by extinction. More than 99 percent of all species that lived on Earth are estimated to be extinct. Estimates of Earths current species range from 10 to 14 million, more recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. In the mid-19th century, Charles Darwin formulated the theory of evolution by natural selection. This teleonomy is the quality whereby the process of natural selection creates and preserves traits that are fitted for the functional roles they perform. The processes by which the changes occur, from one generation to another, are called evolutionary processes or mechanisms, the four most widely recognized evolutionary processes are natural selection, genetic drift, mutation and gene migration. Natural selection and genetic drift sort variation, mutation and gene migration create variation, consequences of selection can include meiotic drive, nonrandom mating and genetic hitchhiking. In the early 20th century the modern evolutionary synthesis integrated classical genetics with Darwins theory of evolution by natural selection through the discipline of population genetics, the importance of natural selection as a cause of evolution was accepted into other branches of biology. Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, evolutionary computation, a sub-field of artificial intelligence, involves the application of Darwinian principles to problems in computer science. The proposal that one type of organism could descend from another type goes back to some of the first pre-Socratic Greek philosophers, such as Anaximander, such proposals survived into Roman times. The poet and philosopher Lucretius followed Empedocles in his masterwork De rerum natura, in contrast to these materialistic views, Aristotelianism considered all natural things as actualisations of fixed natural possibilities, known as forms. This was part of a teleological understanding of nature in which all things have an intended role to play in a divine cosmic order. In the 17th century, the new method of modern science rejected the Aristotelian approach, however, this new approach was slow to take root in the biological sciences, the last bastion of the concept of fixed natural types. The biological classification introduced by Carl Linnaeus in 1735 explicitly recognized the nature of species relationships. Other naturalists of this time speculated on the change of species over time according to natural laws
