Last Glacial Maximum Refugia
Last Glacial Maximum refugia were places ('' refugia'') in which humans and other species survived during the Last Glacial Period in the Northern Hemisphere, around 25,000 to 20,000 years ago. Sub-Saharan Africa and Australia were not affected by the glaciation, although vast areas of those continents were too dry for human habitation of any sort, even by the most specialised and well-adapted foragers. New Zealand had no humans at the time. Some recent archaeological evidence suggests the possibility that human arrival in the Americas may have occurred prior to the Last Glacial Maximum more than 20,000 years ago, including possibly areas adjacent to ice sheets, but research is still in an early stage. The best attested shelters are therefore mainly those in Eurasia. Several of them have been studied.

Europe20000ya
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea wi ...

Würm Glaciation
The Würm glaciation or Würm stage (german: Würm-Kaltzeit or ''Würm-Glazial'', colloquially often also ''Würmeiszeit'' or ''Würmzeit''; cf. ice age), usually referred to in the literature as the Würm (often spelled "Wurm"), was the last glacial period in the Alpine region. It is the youngest of the major glaciations of the region that extended beyond the Alps themselves. Like most of the other ice ages of the Pleistocene epoch, it is named after a river, in this case the Würm in Bavaria, a tributary of the Amper. The Würm ice age can be dated to about 115,000 to 11,700 years ago, but sources differ about the dates, depending on whether the long transition phases between the glacials and interglacials (warmer periods) are allocated to one or other of those periods. The average annual temperatures during the Würm ice age in the Alpine Foreland were below −3 °C (today +7 °C). That has been determined from changes in the vegetation (pollen analysis), as well a ...

Prehistoric Asia
Prehistoric Asia refers to events in Asia during the period of human existence prior to the invention of writing systems or the documentation of recorded history. This includes portions of the Eurasian land mass currently or traditionally considered as the continent of Asia. The continent is commonly described as the region east of the Ural Mountains, the Caucasus Mountains, the Caspian Sea, Black Sea and Red Sea, bounded by the Pacific, Indian, and Arctic Oceans. This article gives an overview of the many regions of Asia during prehistoric times.

Prehistoric Africa
The history of Africa begins with the recent African origin of modern humans, emergence of hominids, archaic humans and — around 300–250,000 years ago—anatomically modern humans (''Homo sapiens''), in East Africa, and continues unbroken into the present as a patchwork of diverse and politically developing nation states. The earliest known recorded history Classical African civilization, arose in Ancient Egypt, and later in Nubia, the Sahel, the Maghreb, and the Horn of Africa. Following the desertification of the Sahara, North African history became entwined with the Middle East and Southern Europe while the Bantu expansion swept from modern day Cameroon (Central Africa) across much of the sub-Saharan continent in waves between around 1000 BC and 1 AD, creating a linguistic commonality across much of the central and Southern continent. During the Middle Ages, Islam spread west from Arabia to Egypt, crossing the Maghreb and the Sahel. Some notable pre-colonial states and ...

Ice Ages
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called ''interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for the ...

Eurasiatic Languages
Eurasiatic is a proposed language macrofamily that would include many language families historically spoken in northern, western, and southern Eurasia. The idea of a Eurasiatic superfamily dates back more than 100 years. Joseph Greenberg's proposal, dating to the 1990s, is the most widely discussed version. In 2013, Mark Pagel and three colleagues published what they believe to be statistical evidence for a Eurasiatic language family. The branches of Eurasiatic vary between proposals, but typically include Altaic ( Mongolic, Tungusic and Turkic), Chukchi-Kamchatkan, Eskimo–Aleut, Indo-European, and Uralic—although Greenberg uses the controversial Uralic-Yukaghir classification instead. Other branches sometimes included are the Kartvelian and Dravidian families, as proposed by Pagel et al., in addition to the language isolates Nivkh, Etruscan and Greenberg's "Korean–Japanese–Ainu". Some proposals group Eurasiatic with even larger macrofamilies, such as Nostratic; agai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Paleolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago, it has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which contributed to the Neanderthal extinction, ex ...

Magdalenian
The Magdalenian cultures (also Madelenian; French: ''Magdalénien'') are later cultures of the Upper Paleolithic and Mesolithic in western Europe. They date from around 17,000 to 12,000 years ago. It is named after the type site of La Madeleine, a rock shelter located in the Vézère valley, commune of Tursac, in France's Dordogne department. Édouard Lartet and Henry Christy originally termed the period ''L'âge du renne'' (the Age of the Reindeer). They conducted the first systematic excavations of the type site, publishing in 1875. The Magdalenian epoch is associated with reindeer hunters, although Magdalenian sites contain extensive evidence for the hunting of red deer, horses, and other large mammals present in Europe toward the end of the last glacial period. The culture was geographically widespread, and later Magdalenian sites stretched from Portugal in the west to Poland in the east, and as far north as France, the Channel Islands, England, and Wales. It is the th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Relict
A glacial relict is a population of a cold-adapted species that has been left behind as the range of the species changed after an ice age ended. Glacial relicts are usually found in enclaves "under relatively benign conditions". Examples: *The biogeography of various aquatic species deemed glacial relicts that are found in Lake Sommen is likely related to a different geography during the early history of the lake. One theory claims that aquatic species were transferred from the Baltic Ice Lake through a natural lock system in connection with a temporary advance of the ice-front during the Younger Dryas. On land, the unusual occurrence of dwarf birch near Sund is also judged to be a leftover from a cold geological past. See also *Biodiversity hotspot *Last Glacial Maximum refugia *Nunatak hypothesis *Rapoport's rule *Relict (biology) In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past.

Jōmon Period
The is the time in Japanese history, traditionally dated between 6,000–300 BCE, during which Japan was inhabited by a diverse hunter-gatherer and early agriculturalist population united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity. The name "cord-marked" was first applied by the American zoologist and orientalist Edward S. Morse, who discovered sherds of pottery in 1877 and subsequently translated it into Japanese as ''Jōmon''.Mason, 14 The pottery style characteristic of the first phases of Jōmon culture was decorated by impressing cords into the surface of wet clay and is generally accepted to be among the oldest in the world. The Jōmon period was rich in tools and jewelry made from bone, stone, shell and antler; pottery figurines and vessels; and lacquerware.Imamura, K.

Kebaran
The Kebaran culture, also known as the Early Epipalaeolithic Near East, Near East Epipalaeolithic, was an archaeological culture in the Eastern Mediterranean area (c. 23,000 to 15,000 BP), named after its type site, Kebara Cave south of Haifa. The Kebaran were a highly mobile nomadic population, composed of hunters and gatherers in the Levant and Sinai Peninsula, Sinai areas who used microliths, microlithic tools. Overview The Kebaran is the last Upper Paleolithic phase of the Levant. Kebaran stone tool Assemblage (archaeology), assemblages are characterized by small, geometric microliths, and are thought to have lacked the specialized grinders and pounders found in later Near Eastern cultures. Small stone tools called microliths and retouched bladelets can be found for the first time. The microliths of this culture period differ greatly from the Aurignacian artifacts. The Kebaran is preceded by the Athlitian phase of the Upper Paleolithic Levantine Aurignacian (formerly called A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsian Culture
The Capsian culture was a Mesolithic and Neolithic culture centered in the Maghreb that lasted from about 8,000 to 2,700 BC. It was named after the town of Gafsa in Tunisia, which was known as Capsa in Roman times. Capsian industry was concentrated mainly in modern Tunisia and Algeria, with some lithic sites attested from southern Spain to Sicily. It is traditionally divided into two horizons, the ''Capsien typique'' (Typical Capsian) and the ''Capsien supérieur'' (Upper Capsian), which are sometimes found in chronostratigraphic sequence. Sometimes, a third period, ''Capsian Neolithic'' (6,200–5,300 BP) is also specified. They represent variants of one tradition, the differences between them being both typological and technological.2005 D. Lubell. Continuité et changement dans l'Epipaléolithique du Maghreb. In, M.
