African Humid Period
The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today. The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in the Earth's axial tilt, changes in vegetation and dust in the Sahara which strengthened the African monsoon, and increased greenhouse gases. During the preceding Last Glacial Maximum, the Sahara contained extensive dune fields and was mostly uninhabited. It was much larger than today, and its lakes and rivers such as Lake Victoria and the White Nile were either dry or at low levels. The humid period began about 14,600–14,500 years ago at the end of Heinrich event 1, simultaneously to the Bølling–Allerød warming. Rivers and lakes such as Lake Chad formed or expanded, glaciers grew on Mount Kilimanjaro and the Sahara retreated. Two major dry fluctuations occurred; during the Younger Dryas ...

Prehistoric Sculpture
Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or moulded or cast. Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. In addition, most ancient sculpture was painted, which has been lost. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cambridge Scholars Publishing
Cambridge Scholars Publishing (CSP) is an academic book publisher based in Newcastle upon Tyne, England. It is not affiliated with the University of Cambridge or Cambridge University Press. It began as the hobby project of a Cambridge alumnus publishing out-of-print Victorian novels. Since then, it has expanded into health science, life science, physical science, and social science. In 2018 it published 729 books. It is known for its aggressive solicitation of authors via email, and uses print on demand techonology to publish a large number of titles every year under a low margin business model, with limited editorial oversight of published works. Although Cambridge Scholars does not charge its authors, it has been listed as a predatory publisher by Cabells' Predatory Reports.

Neontology
Neontology is a part of biology that, in contrast to paleontology, studies and deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The Indian elephant (''Elephas maximus'') is an extant species, and the woolly mammoth (''Mammuthus primigenius'') is an extinct species. * The moose (''Alces alces'') is an extant species, and the Irish elk (''Megaloceros giganteus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species (" Lazarus species"), or if previously known extant species ...

Hypothetical Species
Several species have been assumed to exist, but due to a lack of physical evidence they can only be regarded as potential species. Hypothetical species are usually believed to be extinct. They have caused confusion, as they may have been a separate species, a subspecies, an introduced species or a misidentification. List of hypothetical species Birds * Albin's Macaw * Arkansaw siskin, ''Fringilla spaltria''https://www.audubon.org/news/john-james-audubon-crazy-wrong-or-neither * Barraband's mystery black-breasted twelve-wired bird-of-paradise * Bird of Washington, ''Haliaetus washingtoni'' * Blue-browed fig parrot * Blue Mountain warbler, ''Sylvia montana'' * Blue-thighed lory, ''Lorius tibialis'' * Dominican green-and-yellow macaw, ''Ara atwoodi'' * Carbonated warbler, ''Sylvia carbonata'' * Cuvier's kinglet, ''Regulus cuvieri'' *'' Geoffroyus aureus'' * Guadeloupe amazon, ''Amazona violacea'' * Guadeloupe parakeet, ''Psittacara labati'' * Hypothetical relatives of the Rodrigues ...

The British Museum
The British Museum is a Museum, public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is the largest in the world. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative art, decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections.

Petrified Wood
Petrified wood (from Ancient Greek meaning 'rock' or 'stone'; literally 'wood turned into stone'), is the name given to a special type of ''fossilized wood'', the fossilized remains of terrestrial plant, terrestrial vegetation. ''Petrifaction'' is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The Carbon-based life, organic materials making up cell walls have been replicated with minerals (mostly silica in the form of opal, chalcedony, or quartz). In some instances, the original structure of the stem tissue may be partially retained. Unlike other plant fossils, which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried in water or volcanic ash. The presence of water reduces the availability of oxygen which inhibits aerobic dec ...

Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da S ...

Sahara
The Sahara (, ) is a desert spanning across North Africa. With an area of , it is the largest hot desert in the world and the list of deserts by area, third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic. The name "Sahara" is derived from , a broken plural form of ( ), meaning "desert". The desert covers much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile, Nile Valley in Egypt and the Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south it is bounded by the Sahel, a belt of Tropical and subtropical grasslands, savannas, and shrublands, semi-arid tropical savanna around the Niger River valley and the Sudan (region), Sudan region of sub-Saharan Africa. The Sahara can be divided into several regions, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Tifinagh
Tifinagh ( Tuareg Berber language: ; Neo-Tifinagh: ; Berber Latin alphabet: ; ) is a script used to write the Berber languages. Tifinagh is descended from the ancient Libyco-Berber alphabet. The traditional Tifinagh, sometimes called Tuareg Tifinagh, is still favored by the Tuareg people of the Sahara desert in southern Algeria, northeastern Mali, northern Niger, and northern Burkina Faso for writing the Tuareg languages. Neo-Tifinagh is an alphabet developed by the Berber Academy by adopting Tuareg Tifinagh for use for Kabyle; it has been since modified for use across North Africa. Tifinagh is one of three major competing Berber orthographies alongside the Berber Latin alphabet and the Arabic alphabet. Tifinagh is the official script for Tamazight, an official language of Morocco and Algeria. Outside of symbolic cultural uses, Latin remains the dominant script for writing Berber languages throughout North Africa. The ancient Libyco-Berber script was used by the ancient north ...
