Craniometry Skull 1902
Craniometry is measurement of the cranium (the main part of the skull), usually the human cranium. It is a subset of cephalometry, measurement of the head, which in humans is a subset of anthropometry, measurement of the human body. It is distinct from phrenology, the pseudoscience that tried to link personality and character to head shape, and physiognomy, which tried the same for facial features. However, these fields have all claimed the ability to predict traits or intelligence. It was once intensively practised in anthropology, in particular in physical anthropology in the 19th and the first part of the 20th century. Theories attempting to scientifically justify the segregation of society based on race became popular at this time, one of their prominent figures being Georges Vacher de Lapouge (1854–1936), who divided humanity into various, hierarchized, different " races", spanning from the "Aryan white race, dolichocephalic" (from the Ancient Greek ''kephalê'', head, a ...

Brachycephalic
Brachycephaly (derived from the Ancient Greek '' βραχύς'', 'short' and '' κεφαλή'', 'head') is the shape of a skull shorter than typical for its species. It is perceived as a desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species. In humans, the cephalic disorder is known as flat head syndrome, and results from premature fusion of the coronal sutures, or from external deformation. The coronal suture is the fibrous joint that unites the frontal bone with the two parietal bones of the skull. The parietal bones form the top and sides of the skull. This feature can be seen in Down syndrome. In anthropology, human populations have been characterized as either dolichocephalic (long-headed), mesaticephalic (moderate-headed), or brachycephalic (short-headed). The usefulness of the cephalic index was questioned by Giuseppe Sergi, who argued that cranial morphology provided a better mean ...

Nordic Theory
Nordicism is an ideology of racism which views the historical race concept of the "Nordic race" as an endangered and superior racial group. Some notable and seminal Nordicist works include Madison Grant's book '' The Passing of the Great Race'' (1916); Arthur de Gobineau's '' An Essay on the Inequality of the Human Races'' (1853); the various writings of Lothrop Stoddard; Houston Stewart Chamberlain's '' The Foundations of the Nineteenth Century'' (1899); and, to a lesser extent, William Z. Ripley’s '' The Races of Europe'' (1899). The ideology became popular in the late-19th and 20th centuries among Germanic-speaking people of Northwestern, Central and Northern Europe, as well as in North America and Australia. The belief that the Nordic phenotype is superior to all others was originally embraced as " Anglo-Saxonism" in England and the United States, "Teutonicism" in Germany, and "Frankisism" in Northern France. The notion of the superiority of the "Nordic race" and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugenics
Eugenics ( ; ) is a fringe set of beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have attempted to alter human gene pools by excluding people and groups judged to be inferior or promoting those judged to be superior. In recent years, the term has seen a revival in bioethical discussions on the usage of new technologies such as CRISPR and genetic screening, with a heated debate on whether these technologies should be called eugenics or not. The concept predates the term; Plato suggested applying the principles of selective breeding to humans around 400 BC. Early advocates of eugenics in the 19th century regarded it as a way of improving groups of people. In contemporary usage, the term ''eugenics'' is closely associated with scientific racism. Modern bioethicists who advocate new eugenics characterize it as a way of enhancing individual traits, regardless of group membership. While eugenic principles have be ...

Anders Retzius
Anders Adolph Retzius (13 October 1796 – 18 April 1860), was a Swedish professor of anatomy and a supervisor at the Karolinska Institute in Stockholm. Biography Retzius was born in Lund, Sweden, in 1796. He enrolled at Lund University in 1812 where he studied medicine, and alternated with studies in Copenhagen, until he in 1818 became a licensed doctor of medicine. Through his friendship with Jöns Jakob Berzelius, as early as 1824 he was appointed temporary professor of anatomy at the Karolinska Institute, an institute to which he dedicated much of his strength for many years. In 1830 he was also appointed temporary supervisor there, and in 1840 he was appointed both permanent professor and supervisor. Pathologist Axel Key was one of his students. During the next decades he made many anatomical discoveries, for instance about the finer parts of the teeth, of the skull, of the muscles and of the nervous system. He was also an anthropologist, whose studies of the human crani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Dürer
Albrecht Dürer (; ; hu, Ajtósi Adalbert; 21 May 1471 – 6 April 1528),Müller, Peter O. (1993) ''Substantiv-Derivation in Den Schriften Albrecht Dürers'', Walter de Gruyter. . sometimes spelled in English as Durer (without an umlaut) or Duerer, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe in his twenties due to his high-quality woodcut prints. He was in contact with the major Italian artists of his time, including Raphael, Giovanni Bellini, and Leonardo da Vinci, and from 1512 was patronized by Emperor Maximilian I. Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts series are more Gothic than the rest of his work. His well-known engravings include the three '' Meisterstiche'' (master prints) ''Knight, Death and the Devil'' (1513), '' Sain ...

Bernard Palissy
Bernard Palissy (c. 1510c. 1589) was a French Huguenot potter, hydraulics engineer and craftsman, famous for having struggled for sixteen years to imitate Chinese porcelain. He is best known for his so-called "rusticware", typically highly decorated large oval platters featuring small animals in relief among vegetation, the animals apparently often being moulded from casts taken of dead specimens. It is often difficult to distinguish examples from Palissy's own workshop and those of a number of "followers" who rapidly adopted his style. Imitations and adaptations of his style continued to be made in France until roughly 1800, and then revived considerably in the 19th century. In the 19th century, Palissy's pottery became the inspiration for Mintons Ltd's Victorian majolica, which was exhibited at the London Great Exhibition of 1851 under the name " Palissy ware". Palissy is known for his contributions to the natural sciences, and is famous for discovering principles of geology, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroscience And Intelligence
Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence. Historic approaches to study the neuroscience of intelligence consisted of correlating external head parameters, for example head circumference, to intelligence. Post-mortem measures of brain weight and brain volume have also been used. More recent methodologies focus on examining correlates of intelligence within the living brain using techniques such as magnetic resonance imaging ( MRI), functional MRI (fMRI), electroencephalography (EEG), positron emission tomography and other non-invasive measures of brain structure and activity. Researchers have been able to identify correlates of intelligence within the brain and its functioning. These include overall brain volume, grey matter volume, white matter volu ...

Theory Of Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeleton
A skeleton is the structural frame that supports the body of an animal. There are several types of skeletons, including the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, and the hydroskeleton, a flexible internal skeleton supported by fluid pressure. Vertebrates are animals with a vertebral column, and their skeletons are typically composed of bone and cartilage. Invertebrates are animals that lack a vertebral column. The skeletons of invertebrates vary, including hard exoskeleton shells, plated endoskeletons, or Sponge spicule, spicules. Cartilage is a rigid connective tissue that is found in the skeletal systems of vertebrates and invertebrates. Etymology The term ''skeleton'' comes . ''Sceleton'' is an archaic form of the word. Classification Skeletons can be defined by several attributes. Solid skeletons consist of hard substances, such as bone, cartilage, or cuticle. These can be further ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates.
