Neanderthal
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''H. heidelbergensis'' is also unclear. The oldest potential Neanderthal bones date to 430,000 years ago, but the classification ...

Early Modern Human
Early modern human (EMH) or anatomically modern human (AMH) are terms used to distinguish ''Homo sapiens'' (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans from extinct archaic human species. This distinction is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe. Among the oldest known remains of ''Homo sapiens'' are those found at the Omo-Kibish I archaeological site in south-western Ethiopia, dating to about 233,000 to 196,000 years ago, the Florisbad site in South Africa, dating to about 259,000 years ago, and the Jebel Irhoud site in Morocco, dated about 315,000 years ago. Extinct species of the genus ''Homo'' include ''Homo erectus'' (extant from roughly 2 to 0.1 million years ago) and a number of other species (by some authors considered subspecies of either ''H. sapiens'' or ''H. erectus''). The divergence of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neanderthal 1
Feldhofer 1 or Neanderthal 1 is the scientific name of the 40,000-year-old type specimen fossil of the species ''Homo neanderthalensis'', found in August 1856 in a German cave, the Kleine Feldhofer Grotte in the Neandertal valley, east of Düsseldorf. In 1864 the fossil's description was first published in a scientific magazine and officially named. William King: ''The Reputed Fossil Man of the Neanderthal''. In: ''Quarterly Journal of Science''. Band 1, 1864, S. 88–97Volltext (PDF; 356 kB)/ref> However, the find was not the first Neanderthal fossil discovery. Other Neanderthal fossils had been discovered earlier, but their true nature and significance had not been recognized, and therefore no separate species' name was assigned. The discovery was made by limestone quarry miners. Neanderthal 1 consists of a skullcap, two femora, the three right arm bones, two of the left arm bones, ilium, and fragments of a scapula and ribs. The fossils were given to Johann Carl Fuhlro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neanderthals In Southwest Asia
Southwest Asian Neanderthals were Neanderthals who lived in Turkey, Lebanon, Syria, Palestine, Israel, Iraq, and Iran - the southernmost expanse of the known Neanderthal range. Although their arrival in Asia is not well-dated, early Neanderthals occupied the region apparently until about 100,000 years ago. At this time, ''Homo sapiens'' immigrants seem to have replaced them in one of the first anatomically-modern expansions out of Africa. In their turn, starting around 80,000 years ago, Neanderthals seem to have returned and replaced ''Homo sapiens'' in Southwest Asia. They inhabited the region until about 55,000 years ago. In Southwest Asia Neanderthals have left well-preserved skeletal remains in present-day Israel, Syria, and Iraq. Remains in Turkey, Lebanon, and Iran are fragmentary. No Neanderthal skeletal remains have ever been found to the south of Jerusalem, and although there are Middle Palaeolithic Levallois points in Jordan and in the Arabian peninsula, it is unclear ...

Homo Heidelbergensis
''Homo heidelbergensis'' (also ''H. sapiens heidelbergensis''), sometimes called Heidelbergs, is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene. It was subsumed as a subspecies of ''H. erectus'' in 1950 as ''H. e. heidelbergensis'', but towards the end of the century, it was more widely classified as its own species. It is debated whether or not to constrain ''H. heidelbergensis'' to only Europe or to also include African and Asian specimens, and this is further confounded by the type specimen (Mauer 1) being a jawbone, because jawbones feature few diagnostic traits and are generally missing among Middle Pleistocene specimens. Thus, it is debated if some of these specimens could be split off into their own species or a subspecies of ''H. erectus''. Because the classification is so disputed, the Middle Pleistocene is often called the "muddle in the middle." ''H. heidelbergensis'' is regarded as a chronospecies, evolving from an Africa ...

Neander Valley
The Neandertal (, also , ; sometimes called "the Neander Valley" in English) is a small valley of the river Düssel in the German state of North Rhine-Westphalia, located about east of Düsseldorf, the capital city of North Rhine-Westphalia. The valley lies within the limits of the towns of Erkrath and Mettmann. In August 1856, the area became famous for the discovery of Neanderthal 1, one of the first specimens of ''Homo neanderthalensis'' to be found. The Neandertal was originally a limestone canyon widely known for its rugged scenery, waterfalls and caves. However, industrial quarrying during the 19th and 20th centuries removed most of the limestone and dramatically changed the shape of the valley. It was during such a quarrying operation that the bones of the original Neanderthal man were found in a cave known as Kleine Feldhofer Grotte. Neither the cave nor the cliff in which the bones were located still exist. During the 19th century, the valley was called (Neander's C ...

Archaic Humans
A number of varieties of ''Homo'' are grouped into the broad category of archaic humans in the period that precedes and is contemporary to the emergence of the earliest early modern humans (''Homo sapiens'') around 300 ka. Omo-Kibish I (Omo I) from southern Ethiopia ( 195 or 233 ka), the remains from Jebel Irhoud in Morocco (about 315 ka) and Florisbad in South Africa (259 ka) are among the earliest remains of ''Homo sapiens''. The term typically includes ''Homo neanderthalensis'' (430 ± 25 ka), Denisovans, ''Homo rhodesiensis'' (300–125 ka), ''Homo heidelbergensis'' (600–200 ka), ''Homo naledi'', ''Homo ergaster'', ''Homo antecessor'', and '' Homo habilis''. There is no universal consensus on this terminology, and varieties of "archaic humans" are included under the binomial name of either ''Homo sapiens'' or ''Homo erectus'' by some authors. Archaic humans had a brain size averaging 1,200 to 1,400 cubic centimeters, which overlaps with the range of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William King (geologist)
William King (22 April 1809 – 24 June 1886), was an Anglo-Irish geologist at Queen's College Galway. He was the first (in 1864) to propose that the bones found in the German valley of Neanderthal in 1856 were not of ''Homo sapiens'', but of a distinct species: ''Homo neanderthalensis''. He proposed the name of this new species at a meeting of the British Association in 1863, with the written version published in 1864. Life King was born to William King, a coal worker, and his wife Eleanor née Armstrong who was a confectioner and shop owner. He grew up in Durham and went to study in Sunderland and apprenticed at various times with an ironmonger, book-seller and a librarian. He took an early interest in collecting fossils. He worked at the Newcastle museum in 1841 but left it after six years after conflict with the employers. In 1849 he joined Queen's College Galway and during his long career there published nearly 70 papers and established a museum. He developed a course ...

Human Genome
The human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs. It also includes promoters and their associated gene-regulatory elements, DNA playing structural and replicatory roles, such as scaffolding regions, telomeres, centromeres, and origins of replication, plus large numbers of transposable elements, inserted viral DNA, non-functional pseudogenes and simple, highly-repetitive sequences. Introns make up a large percentage of non-coding DNA. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caveman
The caveman is a stock character representative of primitive humans in the Paleolithic. The popularization of the type dates to the early 20th century, when Neanderthals were influentially described as " simian" or "ape-like" by Marcellin Boule and Arthur Keith. The term "caveman" has its taxonomic equivalent in the now-obsolete binomial classification of '' Homo troglodytes'' (Linnaeus, 1758). Characteristics Cavemen are typically portrayed as wearing shaggy animal hides, and capable of cave painting like behaviorally modern humans of the last glacial period. They are often shown armed with rocks, cattle bone clubs, spears, or sticks with rocks tied to them, and are portrayed as unintelligent, easily frightened, and aggressive. Popular culture also frequently represents cavemen as living with, or alongside, dinosaurs, even though non-avian dinosaurs became extinct at the end of the Cretaceous period, 66 million years before the emergence of the ''Homo sapiens'' sp ...

Europe
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 Continent#Subcontinents, 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 Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Gustav Albert Schwalbe
Gustav Albert Schwalbe, M.D. (1 August 1844 – 23 April 1916) was a German anatomist and anthropologist from Quedlinburg. He was educated at the universities of Berlin, Zurich, and Bonn (M.D. 1866), he became in 1870 privat-docent at the University of Halle, in 1871 privatdozent and prosector at the University of Freiburg in Baden, in 1872 assistant professor at the University of Leipzig, and then professor of anatomy successively at the universities of Jena (1873), Königsberg (1881), and Strassburg (1883) — at that time a German university, Alsace having been annexed to Germany. There he died. Known for his anthropological research of primitive man, Schwalbe considered the Neanderthal to be a direct ancestor of modern humans. Much to the dismay of the Dutch paleontologist Eugène Dubois (1858–1940) who had discovered Java Man, Schwalbe published in 1899 the influential treatise ''Studien über Pithecantropus Erectus'' (Study of Pithecantropus Erectus). In 1869 Schw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altai Mountains
The Altai Mountains (), also spelled Altay Mountains, are a mountain range in Central Asia, Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob River, Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E. The region is inhabited by a sparse but ethnically diverse population, including Russian people, Russians, Kazakh people, Kazakhs, Altai people, Altais, Mongol people, Mongols and Volga Germans, though predominantly represented by indigenous ethnic minorities of semi-nomadic stock. The local economy is based on bovine, sheep, horse animal husbandry, husbandry, hunting, agriculture, forestry, and mining. The Altaic languages, Altaic language family takes its name from this mountain range. Etymology and modern names ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
