History of technology
The history of technology is the history of the invention of tools and techniques and is one of the categories of the history of humanity. Technology can refer to methods ranging from as simple as stone tools to the complex genetic engineering and information technology that has emerged since the 1980s; the term technology comes from the Greek word techne, meaning art and craft, the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to described advancements and changes which affect the environment around us. New knowledge has enabled people to create new things, conversely, many scientific endeavors are made possible by technologies which assist humans in traveling to places they could not reach, by scientific instruments by which we study nature in more detail than our natural senses allow. Since much of technology is applied science, technical history is connected to the history of science. Since technology uses resources, technical history is connected to economic history.
From those resources, technology produces other resources, including technological artifacts used in everyday life. Technological change affects and is affected by, a society's cultural traditions, it is a force for economic growth and a means to develop and project economic, military power and wealth. Many sociologists and anthropologists have created social theories dealing with social and cultural evolution. Some, like Lewis H. Morgan, Leslie White, Gerhard Lenski have declared technological progress to be the primary factor driving the development of human civilization. Morgan's concept of three major stages of social evolution can be divided by technological milestones, such as fire. White argued. For White, "the primary function of culture" is to "harness and control energy." White differentiates between five stages of human development: In the first, people use the energy of their own muscles. In the second, they use the energy of domesticated animals. In the third, they use the energy of plants.
In the fourth, they learn to use the energy of natural resources: coal, gas. In the fifth, they harness nuclear energy. White introduced a formula P=E*T, where E is a measure of energy consumed, T is the measure of the efficiency of technical factors using the energy. In his own words, "culture evolves as the amount of energy harnessed per capita per year is increased, or as the efficiency of the instrumental means of putting the energy to work is increased". Nikolai Kardashev extrapolated his theory, creating the Kardashev scale, which categorizes the energy use of advanced civilizations. Lenski's approach focuses on information; the more information and knowledge a given society has, the more advanced. He identifies four stages of human development, based on advances in the history of communication. In the first stage, information is passed by genes. In the second, when humans gain sentience, they can pass information through experience. In the third, the humans start develop logic. In the fourth, they can develop language and writing.
Advancements in communications technology translate into advancements in the economic system and political system, distribution of wealth, social inequality and other spheres of social life. He differentiates societies based on their level of technology and economy: hunter-gatherer, simple agricultural, advanced agricultural, special. In economics, productivity is a measure of technological progress. Productivity increases. Another indicator of technological progress is the development of new products and services, necessary to offset unemployment that would otherwise result as labor inputs are reduced. In developed countries productivity growth has been slowing since the late 1970s. For example, employment in manufacturing in the United States declined from over 30% in the 1940s to just over 10% 70 years later. Similar changes occurred in other developed countries; this stage is referred to as post-industrial. In the late 1970s sociologists and anthropologists like Alvin Toffler, Daniel Bell and John Naisbitt have approached the theories of post-industrial societies, arguing that the current era of industrial society is coming to an end, services and information are becoming more important than industry and goods.
Some extreme visions of the post-industrial society in fiction, are strikingly similar to the visions of near and post-Singularity societies. The following is a summary of the history of technology by time period and geography: During most of the Paleolithic – the bulk of the Stone Age – all humans had a lifestyle which involved limited tools and few permanent settlements; the first major technologies were tied to survival and food preparation. Stone tools and weapons and clothing were technological developments of major importance during this period. Human ancestors have been using stone and other tools since long before the emergence of Homo sapiens 200,000 years ago; the earliest methods of stone tool making, known as the Oldowan "industry", date back to at least 2.3 million years ago, with the earliest direct evidence of tool usage found in Ethiopia within the Great Rift Valley, dating back to 2.5 million years ago. This era of stone tool use is called the Paleolithic
In agriculture, a terrace is a piece of sloped plane, cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming. This type of landscaping is therefore called terracing. Graduated terrace steps are used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, may be used to support growing crops that require irrigation, such as rice; the Rice Terraces of the Philippine Cordilleras have been designated as a UNESCO World Heritage Site because of the significance of this technique. Terraced paddy fields are used in rice and barley farming in east and southeast Asia, as well as the Mediterranean and South America. Drier-climate terrace farming is common throughout the Mediterranean Basin, where they are used for vineyards, olive trees, cork oak, etc. In the South American Andes, farmers have used terraces, known as andenes, for over a thousand years to farm potatoes and other native crops.
Terraced farming was developed by the Wari culture and other peoples of the south-central Andes before 1000 AD, centuries before they were used by the Inca, who adopted them. The terraces were built to make the most efficient use of shallow soil and to enable irrigation of crops by allowing runoff to occur through the outlet; the Inca built on these, developing a system of canals and puquios to direct water through dry land and increase fertility levels and growth. These terraced farms are found, they provided the food necessary to support the populations of great Inca cities and religious centres such as Machu Picchu. Terracing is used for sloping terrain. At the seaside Villa of the Papyri in Herculaneum, the villa gardens of Julius Caesar's father-in-law were designed in terraces to give pleasant and varied views of the Bay of Naples. Terraced fields are common in islands with steep slopes; the Canary Islands present a complex system of terraces covering the landscape from the coastal irrigated plantations to the dry fields in the highlands.
These terraces, which are named cadenas, are built with stone walls of skillful design, which include attached stairs and channels. In Old English, a terrace was called a "lynch". An example of an ancient Lynch Mill is in Lyme Regis; the water is directed from a river by a duct along a terrace. This set-up was used in steep hilly areas in the UK. In Japan, some of the 100 Selected Terraced Rice Fields, from Iwate in the north to Kagoshima in the south, are disappearing, but volunteers are helping the farmers both to maintain their traditional methods and for sightseeing purposes.

History of agriculture
The history of agriculture records the domestication of plants and animals and the development and dissemination of techniques for raising them productively. Agriculture began independently in different parts of the globe, included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. Wild grains were collected and eaten from at least 20,000 BC. From around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, lentils, bitter vetch, chick peas, flax – were cultivated in the Levant. Rye may have been cultivated earlier but this remains controversial. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BC, followed by sheep between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BC.
Sorghum was domesticated in the Sahel region of Africa by 5000 BC. In the Andes of South America, the potato was domesticated between 8000 BC and 5000 BC, along with beans, llamas and guinea pigs. Bananas were hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BC. Cotton was domesticated in Peru by 3600 BC. Camels were domesticated late around 3000 BC; the Bronze Age, from c. 3300 BC, witnessed the intensification of agriculture in civilizations such as Mesopotamian Sumer, ancient Egypt, the Indus Valley Civilisation of South Asia, ancient China, ancient Greece. During the Iron Age and era of classical antiquity, the expansion of ancient Rome, both the Republic and the Empire, throughout the ancient Mediterranean and Western Europe built upon existing systems of agriculture while establishing the manorial system that became a bedrock of medieval agriculture. In the Middle Ages, both in the Islamic world and in Europe, agriculture was transformed with improved techniques and the diffusion of crop plants, including the introduction of sugar, rice and fruit trees such as the orange to Europe by way of Al-Andalus.
After the voyages of Christopher Columbus in 1492, the Columbian exchange brought New World crops such as maize, sweet potatoes, manioc to Europe, Old World crops such as wheat, barley and turnips, livestock including horses, cattle and goats to the Americas. Irrigation, crop rotation, fertilizers were introduced soon after the Neolithic Revolution and developed much further in the past 200 years, starting with the British Agricultural Revolution. Since 1900, agriculture in the developed nations, to a lesser extent in the developing world, has seen large rises in productivity as human labour has been replaced by mechanization, assisted by synthetic fertilizers and selective breeding; the Haber-Bosch process allowed the synthesis of ammonium nitrate fertilizer on an industrial scale increasing crop yields. Modern agriculture has raised social and environmental issues including water pollution, genetically modified organisms and farm subsidies. In response, organic farming developed in the twentieth century as an alternative to the use of synthetic pesticides.
Scholars have developed a number of hypotheses to explain the historical origins of agriculture. Studies of the transition from hunter-gatherer to agricultural societies indicate an antecedent period of intensification and increasing sedentism. Current models indicate that wild stands, harvested started to be planted, but were not domesticated. Localised climate change is the favoured explanation for the origins of agriculture in the Levant; when major climate change took place after the last ice age, much of the earth became subject to long dry seasons. These conditions favoured annual plants which die off in the long dry season, leaving a dormant seed or tuber. An abundance of storable wild grains and pulses enabled hunter-gatherers in some areas to form the first settled villages at this time. Early people began altering communities of flora and fauna for their own benefit through means such as fire-stick farming and forest gardening early. Exact dates are hard to determine, as people collected and ate seeds before domesticating them, plant characteristics may have changed during this period without human selection.
An example is the semi-tough rachis and larger seeds of cereals from just after the Younger Dryas in the early Holocene in the Levant region of the Fertile Crescent. Monophyletic characteristics were attained without any human intervention, implying that apparent domestication of the cereal rachis could have occurred quite naturally. Agriculture began independently in different parts of the globe, included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin; some of the earliest known domestications were of animals. Domestic pigs had multiple centres of origin in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago. Sheep were domesticated in Mesopotamia between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Camels were domesticated late around 3000 BC, it was not until after 9500 BC that the eight so-called founder crops of agriculture appear: first emmer and einkorn wheat hulled barley, lenti
Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires and bury their dead. There are several factors that made the evolution of prehistoric technology necessary. One of the key factors is behavioral modernity of the developed brain of Homo sapiens capable of abstract reasoning, language and problem solving; the advent of agriculture resulted in lifestyle changes from nomadic lifestyles to ones lived in homes, with domesticated animals, land farmed using more varied and sophisticated tools. Art, architecture and religion evolved over the course of the prehistoric periods; the Stone Age is a broad prehistoric period during which stone was used in the manufacture of implements with a sharp edge, a point, or a percussion surface.
The period lasted 2.5 million years, from the time of early hominids to Homo sapiens in the Pleistocene era, ended between 6000 and 2000 BCE with the advent of metalworking. The Stone Age lifestyle was that of hunter-gatherers who traveled to hunt game and gather wild plants, with minimal changes in technology; as the last glacial period of the current ice age neared its end, large animals like the mammoth and bison antiquus became extinct and the climate changed. Humans adapted by maximizing the resources in local environments and eating a wider range of wild plants and hunting or catching smaller game. Domestication of plants and animals with early stages in the Old World Mesolithic and New World Archaic periods led to significant changes and reliance on agriculture in the Old World Neolithic and New World Formative stage; the agricultural life led to significant technological advancements. Although Paleolithic cultures left no written records, the shift from nomadic life to settlement and agriculture can be inferred from a range of archaeological evidence.
Such evidence includes ancient tools, cave paintings, other prehistoric art, such as the Venus of Willendorf. Human remains provide direct evidence, both through the examination of bones, the study of mummies. Though concrete evidence is limited and historians have been able to form significant inferences about the lifestyle and culture of various prehistoric peoples, the role technology played in their lives; the Lower Paleolithic period was the earliest subdivision of the Old Stone Age. It spans the time from around 2.5 million years ago when the first evidence of craft and use of stone tools by hominids appears in the current archaeological record, until around 300,000 years ago, spanning the Oldowan and Acheulean lithic technology. Early human used stone tool technology, such as a hand axe, similar to that used by primates, which are found to have intelligence levels of modern children aged 3 to 5 years. Intelligence and use of technology did not change much for millions of years; the first "Homo" species began with Homo habilis about 2.4 to 1.5 million years ago.
Homo habilis created. Homo ergaster lived in eastern and southern Africa about 2.5 to 1.7 million years ago and used more diverse and sophisticated stone tools than its predecessor, Homo habilis, including having refined the inherited Oldowan tools and developed the first Acheulean bifacial axes. Homo erectus lived about 1.8 to 1.3 million years ago in West Asia and Africa and is thought to be the first hominid to hunt in coordinated groups, use complex tools, care for infirm or weaker companions. Homo antecessor the earliest hominid in Northern Europe lived from 1.2 million to 800,000 years ago and used stone tools. Homo heidelbergensis lived between 600,000 and 400,000 years ago and used stone tool technology similar the Acheulean tools used by Homo erectus. European and Asian sites dating back 1.5 million years ago seem to indicate controlled use of fire by Homo erectus. A northern Israel site from about 690,000 to 790,000 years ago suggests. Homo heidelbergensis may have been the first species to bury their dead about 500,000 years ago.
The Middle Paleolithic period occurred in Europe and the Near East, during which the Neanderthals lived. The earliest evidence of settlement in Australia dates to around 40,000 years ago when modern humans crossed from Asia by island-hopping; the Bhimbetka rock shelters exhibit the earliest traces of human life in India, some of which are 30,000 years old. Homo neanderthalensis used Mousterian Stone tools that date back to around 300,000 years ago and include smaller, knife-like and scraper tools, they buried their dead in shallow graves along with stone tools and animal bones, although the reasons and significance of the burials are disputed. Homo sapiens, the only living species in the genus Homo, originated in Africa about 200,000 years ago; as compared to their predecessors, Homo sapiens had greater mental capability and ability to walk erect, which provided freed hands for manipulating objects and far greater use of tools. There was art created during this period. Intentional burial with grave goods, may be one of the earliest detectable forms of religious practice since it may signify a "concern for the dead that transcends daily life."
The earliest undisputed human burial so far dates back 130,000 years. Human skeletal remains stained with red ochre w
A granary is a storehouse or room in a barn for threshed grain or animal feed. Ancient or primitive granaries are most made out of pottery. Granaries are built above the ground to keep the stored food away from mice and other animals. From ancient times grain has been stored in bulk; the oldest granaries yet found date back to 9500 BC and are located in the Pre-Pottery Neolithic A settlements in the Jordan Valley. The first were located in places between other buildings; however beginning around 8500 BC, they were moved inside houses, by 7500 BC storage occurred in special rooms. The first granaries measured 3 x 3 m on the outside and had suspended floors that protected the grain from rodents and insects and provided air circulation; these granaries are followed by those in Mehrgarh in the Indus Valley from 6000 BC. The ancient Egyptians made a practice of preserving grain in years of plenty against years of scarcity; the climate of Egypt being dry, grain could be stored in pits for a long time without discernible loss of quality.
A silo was a pit for storing grain. It is distinct from a granary, an above-ground structure. Simple storage granaries raised up on four or more posts appeared in the Yangshao culture in China and after the onset of intensive agriculture in the Korean peninsula during the Mumun pottery period as well as in the Japanese archipelago during the Final Jōmon/Early Yayoi periods. In the archaeological vernacular of Northeast Asia, these features are lumped with those that may have functioned as residences and together are called'raised floor buildings'. In vernacular architecture of Indonesian archipelago granaries are made of wood and bamboo materials and most of them are built raised up on four or more posts to avoid rodents and insects. Examples of Indonesian granary is Sundanese Minang rangkiang. In Great Britain small granaries were built on mushroom-shaped stumps called staddle stones, they were built of timber frame construction and had slate roofs. Larger ones were similar to linhays, but with the upper floor enclosed.
Access to the first floor was via stone staircase on the outside wall. Towards the close of the 19th century, warehouses specially intended for holding grain began to multiply in Great Britain. There are climatic difficulties in the way of storing grain in Great Britain on a large scale, but these difficulties have been overcome. Modern grain farming operations use manufactured steel granaries to store grain on-site until it can be trucked to major storage facilities in anticipation of shipping; the large mechanized facilities seen in Russia and North America are known as grain elevators. Grain must be kept away from moisture for as long as possible to preserve it in good condition and prevent mold growth. Newly harvested grain brought into a granary tends to contain excess moisture, which encourages mold growth leading to fermentation and heating, both of which are undesirable and affect quality. Fermentation spoils grain and may cause chemical changes that create poisonous mycotoxins. One traditional remedy is to spread the grain in thin layers on a floor, where it is turned to aerate it thoroughly.
Once the grain is sufficiently dry it can be transferred to a granary for storage. A modern variation on this, is to use a grain auger to move grain stored in one granary to another. In modern silos, grain is force-aerated in situ or circulated through external grain drying equipment.

A sickle, bagging hook or reaping-hook, is a hand-held agricultural tool designed with variously curved blades and used for harvesting, or reaping, grain crops or cutting succulent forage chiefly for feeding livestock, either freshly cut or dried as hay. Falx was a synonym but was used to mean any of a number of tools that had a curved blade, sharp on the inside edge such as a scythe. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved of iron and steel; this great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is found in modern grain-harvesting machines and in some kitchen knives; the development of the sickle in Mesopotamia can be traced back to times that pre-date the Neolithic Era. Large quantities of sickle blades have been excavated in sites surrounding Israel that have been dated to the Epipaleolithic era.
Formal digs in Wadi Ziqlab, Jordan have unearthed various forms of early sickle blades. The artifacts possessed a jagged edge; this intricate ‘tooth-like’ design showed a greater degree of design and manufacturing credence than most of the other artifacts that were discovered. Sickle blades found during this time were made of flint and used in more of a sawing motion than with the more modern curved design. Flints from these sickles have been discovered near Mt. Carmel, which suggest the harvesting of grains from the area about 10,000 years ago; the sickle had a profound impact on the Agricultural Revolution by assisting in the transition to farming and crop based lifestyle. It is now accepted that the use of sickles led directly to the domestication of Near Eastern Wild grasses. Research on domestication rates of wild cereals under primitive cultivation found that the use of the sickle in harvesting was critical to the people of early Mesopotamia; the narrow growing season in the area and the critical role of grain in the late Neolithic Era promoted a larger investment in the design and manufacture of sickle over other tools.
Standardization to an extent was done on the measurements of the sickle so that replacement or repair could be more immediate. It was important that the grain be harvested at the appropriate time at one elevation so that the next elevation could be reaped at the proper time; the sickle provided a more efficient option in collecting the grain and sped up the developments of early agriculture. The sickle remained common both in the Ancient Near East and in Europe. Numerous sickles have been found deposited in hoards in the context of the European Urnfield culture, suggesting a symbolic or religious significance attached to the artifact. In archaeological terminology, Bronze Age sickles are classified by the method of attaching the handle. E.g. the knob-sickle is so called because of a protruding knob at the base of the blade which served to stabilize the attachment of the blade to the handle. The sickle played a prominent role in the Druids' Ritual of oak and mistletoe as described from a single passage in Pliny the Elder's Natural History: Due to this passage, despite the fact that Pliny does not indicate the source on which he based this account, some branches of modern Druidry have adopted the sickle as a ritual tool.
The sickle has been discovered in southwest North America with a unique structure. These sickles are said to have originated from the Far East. There is evidence that Kodiak islanders had for cutting grass “sickles made of a sharpened animal shoulder blade”; the artifacts found in present-day Arizona and New Mexico resemble curved tools that were made from the horns of mountain sheep. A similar site discovered sickles made from other material such as the Caddo Sickle, made from a deer mandible. Scripture from early natives document the use of these sickles in the cutting of grass; the instruments ranged from 13 to 16 inches tip to tip. Several other digs in eastern Arizona uncovered wooden sickles that were shaped in a similar fashion; the handles of the tools help describe how the tool was held in such a way so that the inner portion that contained the cutting surface could serve as a gathering surface for the grain. Sickles were sharpened by scraping a shape beveled edge with a coarse tool; this action has left marks on artifacts.
The sharpening process was necessary to keep the cutting edge from being dulled after extended use. The edge is seen to be quite polished, which in part proves that the instrument was used to cut grass. After collection, the grass was used as material to create bedding; the sickle in general provided the convenience of cutting the grass as well as gathering in one step. In South America, the sickle is used as a tool to harvest rice. Rice clusters are left to dry in the sun; the genealogy of sickles with serrated edge reaches back to the Stone Age, when individual pieces of flint were first attached to a “blade body” of wood or bone. Teeth have been cut with hand-held chisels into iron, steel-bladed sickles for a long time. In many countries on the African continent and South America as well as the Near and Far East this is still the case in the regions within these large geographies where the traditional village blacksmith remains alive and well.

Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, biofacts or ecofacts and cultural landscapes. Archaeology can be considered a branch of the humanities. In North America archaeology is a sub-field of anthropology, while in Europe it is viewed as either a discipline in its own right or a sub-field of other disciplines. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, the study of fossil remains, it is important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world. Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time.
The discipline involves surveying and analysis of data collected to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research, it draws upon anthropology, art history, ethnology, geology, literary history, semiology, textual criticism, information sciences, statistics, paleography, paleontology and paleobotany. Archaeology developed out of antiquarianism in Europe during the 19th century, has since become a discipline practiced across the world. Archaeology has been used by nation-states to create particular visions of the past. Since its early development, various specific sub-disciplines of archaeology have developed, including maritime archaeology, feminist archaeology and archaeoastronomy, numerous different scientific techniques have been developed to aid archaeological investigation. Nonetheless, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, opposition to the excavation of human remains.
The science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with particular attention to ancient artifacts and manuscripts, as well as historical sites. Antiquarianism focused on the empirical evidence that existed for the understanding of the past, encapsulated in the motto of the 18th-century antiquary, Sir Richard Colt Hoare, "We speak from facts not theory". Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries. In Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Flavio Biondo, an Italian Renaissance humanist historian, created a systematic guide to the ruins and topography of ancient Rome in the early 15th century, for which he has been called an early founder of archaeology. Antiquarians of the 16th century, including John Leland and William Camden, conducted surveys of the English countryside, drawing and interpreting the monuments that they encountered.
One of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other field monuments in southern England, he was ahead of his time in the analysis of his findings. He attempted to chart the chronological stylistic evolution of handwriting, medieval architecture and shield-shapes. Excavations were carried out by the Spanish military engineer Roque Joaquín de Alcubierre in the ancient towns of Pompeii and Herculaneum, both of, covered by ash during the Eruption of Mount Vesuvius in AD 79; these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and human shapes, as well the unearthing of frescos, had a big impact throughout Europe. However, prior to the development of modern techniques, excavations tended to be haphazard; the father of archaeological excavation was William Cunnington. He undertook excavations in Wiltshire from around 1798.
Cunnington made meticulous recordings of Neolithic and Bronze Age barrows, the terms he used to categorize and describe them are still used by archaeologists today. One of the major achievements of 19th-century archaeology was the development of stratigraphy; the idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton and Charles Lyell. The application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites. In the third and fourth decades of the 19th-century, archaeologists like Jacques Boucher de Perthes and Christian Jürgensen Thomsen began to put the artifacts they had found in chronological order. A major figure in the development of archaeology into a rigorous science was the army officer and ethnologist, Augustus Pitt Rivers, who began excavations on his land in England in the 1880s, his approach was methodical by the standards of the time, he is regarded as the first scientific archaeologist.
He arranged his artifacts by type or "typologically, within types by date or "chronologically"
