Brillenhöhle Cave
The Brillenhöhle (, literally ''spectacles cave'') is a cave ruin, located west of Ulm on the Swabian Alb in south-western Germany, where archaeological excavations have documented human habitation since as early as 30,000 years ago. Excavated by Gustav Riek from 1955 to 1963, the cave's Upper Paleolithic layers contain a sequence of Aurignacian, Gravettian and Magdalenian artifacts. In 1956 the first human fossils were discovered within a fireplace in the center of the cave, a discovery which made important contributions to the foundational understanding of the Magdalenian culture of central Europe. Site Brillenhöhle is located in the Ach Valley, lying about above the Ach River below. The site derives its name from the two holes in the cave's ceiling, which together resemble a pair of spectacles. The cave is essentially a single room with a diameter of , an average height of and a length of . A small side cave of width and height, called ''Vespershöhle'' runs from the ...

Silex
Separation of isotopes by laser excitation (SILEX) is a process for enriching uranium to fuel nuclear reactors that may also present a growing nuclear weapons proliferation risk. It is strongly suspected that SILEX utilizes laser condensation repression to excite a vibrational mode of the uranium-235 isotope in uranium hexaflouride (UF6), allowing this lighter molecule to move more rapidly to the outer rim of a gaseous jet and resist condensing compared to the heavier, unexcited 238UF6. This differs greatly from previous methods of laser enrichment explored for their commercial prospects: one using atomic uranium (Atomic Vapor Laser Isotope Separation (AVLIS)) and another molecular method that uses lasers to dissociate a fluorine atom from 235UF6 (Molecular Laser Isotope Separation (MLIS)), allowing the enriched product to precipitate out as a solid. While the Australian company Silex Systems Limited is the most prominent developer of this technology (as part of the Global Laser En ...

Haplogroup U (mtDNA)
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic. Its various subclades (labelled U1–U9, diverging over the course of the Upper Paleolithic) are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands. Origins Haplogroup U descends from the haplogroup R mtDNA branch of the phylogenetic tree. The defining mutations (A11467G, A12308G, G12372A) are estimated to have arisen between 43,000 and 50,000 years ago, in the early Upper Paleolithic (around 46,530 ± 3,290 years before present, with a 95% confidence interval per Behar et al., 2012). Ancient DNA classified as belonging to the U* mitochondrial haplogroup has been recovered from human skeletal remains found in Western Siberia, which have been dated to c. 45,000 years ago.

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parietal Bone
The parietal bones ( ) are two bones in the skull which, when joined at a fibrous joint known as a cranial suture, form the sides and roof of the neurocranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles. It is named from the Latin ''paries'' (''-ietis''), wall. Surfaces External The external surface [Fig. 1] is convex, smooth, and marked near the center by an eminence, the parietal eminence (''tuber parietale''), which indicates the point where ossification commenced. Crossing the middle of the bone in an arched direction are two curved lines, the superior and inferior temporal lines; the former gives attachment to the temporal fascia, and the latter indicates the upper limit of the muscular origin of the temporal muscle. Above these lines the bone is covered by a tough layer of fibrous tissue – the epicranial aponeurosis; below them it forms part of the temporal fossa, and affords attachment to the temporal mu ...

Landesmuseum Württemberg
The Landesmuseum Württemberg (Württemberg State Museum) is the main historical museum of the Württemberg part of the German state of Baden-Württemberg. It emerged from the 16th-century “Kunstkammer” ( Cabinet of art and curiosities) of the dukes, later kings, of Württemberg who resided in Stuttgart. As a museum it was founded in 1862 by King William I. Collections in Stuttgart and Waldenbuch The museum's main location is the Old Castle in Stuttgart. The nearby granary and the cellar of the New Castle also contain parts of the collections as well as Waldenbuch Castle outside of Stuttgart.

Bronze Age
The Bronze Age () was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age is the middle principal period of the three-age system, following the Stone Age and preceding the Iron Age. Conceived as a global era, the Bronze Age follows the Neolithic, with a transition period between the two known as the Chalcolithic. The final decades of the Bronze Age in the Mediterranean basin are often characterised as a period of widespread societal collapse known as the Late Bronze Age collapse (), although its severity and scope are debated among scholars. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere. Bronze Age cultures were the first to History of writing, develop writin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Ochre
Ochre ( ; , ), iron ochre, or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as red ochre (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. A range of other minerals may also be included in the mixture:Krivovichev V.

Human Cannibalism
Human cannibalism is the act or practice of Human, humans eating the Meat, flesh or internal organs of other human beings. A person who practices cannibalism is called a cannibal. The meaning of "cannibalism" has been extended into zoology to describe animals consuming parts of individuals of the same species as food. Early modern human, Anatomically modern humans, Neanderthals, and ''Homo antecessor'' are known to have practised cannibalism to some extent in the Pleistocene. Cannibalism was occasionally practised in Egypt during ancient Egypt, ancient and Roman Egypt, Roman times, as well as later during severe famines. The Island Caribs of the Lesser Antilles, whose name is the origin of the word ''cannibal'', acquired a long-standing reputation as eaters of human flesh, reconfirmed when their legends were recorded in the 17th century. Some controversy exists over the accuracy of these legends and the prevalence of actual cannibalism in the culture. Reports describing cannib ...

Cave Bear
The cave bear (''Ursus spelaeus'') is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word ''cave'' and the scientific name ''spelaeus'' are used because fossils of this species were mostly found in caves. This reflects the views of experts that cave bears spent more time in caves than the brown bear, frequently using them to hibernate during the winter months. Unlike brown bears, cave bears are thought to have been almost entirely or exclusively herbivorous. Cave bears exhibit a great degree of size, morphological and genetic variability, and Late Pleistocene cave bears are often (though not universally) considered to be species complex of up to 6 different species. Taxonomy Cave bear skeletons were first described in 1774 by Johann Friedrich Esper, in his book ''Newly Discovered Zoolites of Unknown Four Footed Animals''. While scientists at the time considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wild Horse
The wild horse (''Equus ferus'') is a species of the genus Equus (genus), ''Equus'', which includes as subspecies the modern domestication of the horse, domesticated horse (''Equus ferus caballus'') as well as the Endangered species, endangered Przewalski's horse (''Equus ferus przewalskii'', sometimes treated as a separate species i.e. ''Equus przewalskii''). The European wild horse, also known as the tarpan, that went extinct in the late 19th or early 20th century has previously been treated as the nominate subspecies of wild horse, ''Equus ferus ferus'', but more recent studies have cast doubt on whether tarpans were truly wild or if they actually were feral horses or hybrids.Tadeusz Jezierski, Zbigniew Jaworski: ''Das Polnische Konik. Die Neue Brehm-Bücherei Bd. 658'', Westarp Wissenschaften, Hohenwarsleben 2008, Other subspecies of ''Equus ferus'' may have existed and could have been the stock from which domesticated horses are descended.
