Lawrence H. Keeley
Lawrence H. Keeley (August 24, 1948 – October 11, 2017) was an American archaeologist best known for pioneering the field of microwear analysis of lithics. He is also known for his 1996 book, ''War Before Civilization: The Myth of the Peaceful Savage''. Keeley worked as a professor of archaeology at the University of Illinois Chicago. Early life Keeley was born and raised in Cupertino, California, where he attended Cupertino High School. After high school, he went on to earn his B.A. in Anthropology from San José State University in 1970. Keeley initially pursued graduate education at the University of Oregon, but his professors encouraged him to enroll in a British university. After transferring, Keeley earned his Ph.D. in Archaeology at the University of Oxford in 1977. Career Keeley had a short postdoctoral appointment at Musée royal de l'Afrique centrale in 1977. He began his academic career at the University of Illinois Chicago the following year. Keeley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupertino, CA
Cupertino ( ) is a city in Santa Clara County, California, United States, directly west of San Jose, California, San Jose on the western edge of the Santa Clara Valley with portions extending into the foothills of the Santa Cruz Mountains. The population was 60,381 as of the 2020 United States census, 2020 census. The city is the home of Apple Inc., headquartered within the city at Apple Park. Named for a local creek by Spanish explorer Juan Bautista de Anza's cartographer bearing the name of Saint Joseph of Cupertino, Cupertino was officially incorporated in 1955, though it saw economic activity in the early 19th century. The area was originally an agricultural community producing prunes, apricots and Cherry, cherries, with a winery joining the ranks by the 19th century. Cupertino grew immensely during the 1950s due to the suburban housing boom experienced after the World War II, Second World War, concurring with the earliest roots of Silicon Valley developing near Cupertino. ...

Assistant Professor
Assistant professor is an academic rank just below the rank of an associate professor used in universities or colleges, mainly in the United States, Canada, Japan, and South Korea. Overview This position is generally taken after earning a doctoral degree and sometimes after several years of holding one or more postdoctoral research A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). Postdocs most commonly, but not always, have a temporary acade ...er positions. It is below the position of associate professor at most universities and is equivalent to the rank of lecturer at most Commonwealth universities. In the United States, assistant professor is often the first position held in a tenure track, although it can also be a non-tenure track position. A typical professorship sequence is assistant professor, associate professor, and full professo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithic Flakes
In archaeology, a lithic flake is a "portion of rock (geology), rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a lithic core, core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler Tine (structural), tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often (termination type, but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion.

Koobi Fora
Koobi Fora refers primarily to a region around Koobi Fora Ridge, located on the eastern shore of Lake Turkana in the territory of the nomadic Gabbra people. According to the National Museums of Kenya, the name comes from the Gabbra language: The ridge itself is an outcrop of mainly Pliocene/Pleistocene sediments. It is composed of claystones, siltstones, and sandstones that preserve numerous fossils of terrestrial mammals, including early hominin species. Presently, the ridge is being eroded into a badlands terrain by a series of ephemeral rivers that drain into the northeast portion of modern Lake Turkana. In 1968 Richard Leakey established the Koobi Fora Base Camp on a large sandspit projecting into the lake near the ridge, which he called the Koobi Fora Spit. Consequently, the government of Kenya in 1973 reserved the region as Sibiloi National Park, establishing a headquarters for the National Museums of Kenya on Koobi Fora Spit. The reserve is well-maintained and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldowan
The Oldowan (or Mode I) was a widespread stone tool archaeological industry during the early Lower Paleolithic spanning the late Pliocene and the first half of the Early Pleistocene. These early tools were simple, usually made by chipping one, or a few, flakes off a stone using another stone. Oldowan tools were used during over a period spanning from 2.9 million years ago up until at least 1.7 million years ago (Ma), by ancient hominins (early humans) across much of Africa. This technological industry was followed by the more sophisticated Acheulean industry (two sites associated with ''Homo erectus'' at Gona in the Afar Region of Ethiopia dating from 1.5 and 1.26 million years ago have both Oldowan and Acheulean tools). The term ''Oldowan'' is taken from the site of Olduvai Gorge in Tanzania, where the first Oldowan stone tools were discovered by the archaeologist Louis Leakey in the 1930s. However, some contemporary archaeologists and palaeoanthropologists prefer to use th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicholas Toth
Nicholas Patrick Toth (born September 22, 1952) is an American archaeologist and paleoanthropologist. He is a Professor in the Cognitive Science Program at Indiana University and is a founder and co-director of the Stone Age Institute. Toth's archaeological and experimental research has focused on the stone tool technology of Early Stone Age hominins who produced Oldowan and Acheulean artifacts which have been discovered across Africa, Asia, the Middle East, and Europe. He is best known for his experimental work, with Kathy Schick, including their work with the bonobo (“pygmy chimpanzee”) Kanzi who they taught to make and use simple stone tools similar to those made by our Early Stone Age ancestors. Early life and education Toth was born and grew up in Cleveland, Ohio. He graduated from Brooklyn High School in 1970 and in 1974 earned a B.A. with distinction in Liberal Arts and Anthropology from Western College in Oxford, Ohio. Toth attended Oxford University, England wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UCL Institute Of Archaeology
UCL's Institute of Archaeology is an academic department of the Social & Historical Sciences Faculty of University College London (UCL) which it joined in 1986 having previously been a school of the University of London. It is currently one of the largest centres for the study of archaeology, cultural heritage and museum studies in the world, with over 100 members of staff and 600 students housed in a 1950s building on the north side of Gordon Square in the Bloomsbury area of Central London. History The Institute of Archaeology had its origins in Mortimer Wheeler's vision of a centre for archaeological training in the United Kingdom, which he conceived in the 1920s. Wheeler and Tessa Verney Wheeler, his wife and an archaeologist in her own right, lobbied colleagues and gathered funds to open the institute. The Wheeler's ambitions were realised when the institute was officially opened in 1937, with Mortimer Wheeler as its first director. Among its early members of staff were so ...

University Of London
The University of London (UoL; abbreviated as Lond or more rarely Londin in Post-nominal letters, post-nominals) is a collegiate university, federal Public university, public research university located in London, England, United Kingdom. The university was established by royal charter in 1836 as a degree-awarding examination board for students holding certificates from University College London, King's College London and "other such institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom". It is one of three institutions to have claimed the title of the Third-oldest university in England debate, third-oldest university in England. It moved to a federal structure with constituent colleges in 1900. It is now incorporated by its fourth (1863) royal charter and governed by the University of London Act 2018 (c. iii). The university consists of Member institutions of the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blinded Experiment
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints. During the course of an experiment, a participant becomes unblinded if they deduce or otherwise obtain information that has been masked to them. For example, a patient who experiences a side effect may corr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microscopy
Microscopy is the technical field of using microscopes to view subjects too small to be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical microscope, optical, electron microscope, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection (physics), reflection, or refraction of electromagnetic radiation/electron beams interacting with the Laboratory specimen, specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscope, transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy).

Artifact (archaeology)
An artifact or artefact (British English) is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance; it is defined as an object recovered by archaeological endeavor, including cultural artifacts (of archaeological culture, cultural interest). "Artifact" is the general term used in archaeology, while in museums the equivalent general term is normally "object", and in art history perhaps artwork or a more specific term such as "carving". The same item may be called all or any of these in different contexts, and more specific terms will be used when talking about individual objects, or groups of similar ones. Artifacts exist in many different forms and can sometimes be confused with Biofact (archaeology), ecofacts and Feature (archaeology), features; all three of these can sometimes be found together at archaeological sites. They can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Use-wear Analysis
Use-wear analysis is a method in archaeology Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, ... to identify the functions of artifact tools by closely examining their working surfaces and edges. It is mainly used on stone tools, and is sometimes referred to as "traceological analysis" (from the neologism ''traceology''). In studying the wear on a lithics, different techniques are often used. A distinction is often made between use-wear and microwear analysis. Use-wear uses an approach of low magnification study while micro-wear employs high magnification; this raises contentions as to which approach is more useful. Therefore, use-wear studies regularly employ magnification up to 50x, while magnification beyond 50x is relegated to microwear analysis. In addition to the two groups o ...
