Neanderthal manNeanderthal man(nēăn`dərthôl', –tôl') orNeandertal man(–tôl'), a species of Homo, the genus to which contemporary humans belong, known as H. neandertalensis after Neanderthal (now Neandertal), Germany, the valley where the first specimen to be identified was found.Anatomically Neanderthals were somewhat shorter but much more robust than contemporary H. sapiens, and appear to have been much stronger than modern humans. Distinctive cranial features of Neanderthals included prominent brow ridges, low, sloping foreheads, the lack of a protuding chin, a heavy, forward-jutting jaw, and larger front teeth. The shoulders and pelvis were wider, the rib cage more conical in shape, and the forearms and lower legs shorter. When placed in an evolutionary perspective, Neanderthal anatomy can give the impression of a large and somewhat "primitive" hominin, as though the evolutionary trajectory of Homo sapiens had somehow reversed itself. This impression is offset somewhat by the Neanderthal braincase, which measured on average about 1600 cc, larger than that of contemporary H. sapiens. The unique anatomy of Neanderthals probably reflects the fact that they were the first hominin to spend extensive periods of time in extremely cold environments, having evolved in Europe at the onset of the most recent glaciation of that continent (see Pleistocene epochPleistocene epoch Neanderthal phylogeny remains somewhat enigmatic, despite the relative abundance of fossil remains. Among African and Asian fossil remains, the reduction in skull and brow ridge thickness and the expansion of the forehead proceeded gradually, with anatomically modern H. sapiens present by 150,000 years ago in S and E Africa. In contrast, by 125,000 years ago, the classic Neanderthal form arose in Europe; it probably persisted in Europe until about 40,000 years ago. Culturally, Neanderthals are closely associated with a stone-tool tradition known as the Mousterian of the middle PaleolithicPaleolithic period Controversy has surrounded the fate of Neanderthals. Some have argued that their extinction was due to being wiped by modern H. sapiens, and others have argued relatively low population numbers and the stresses caused by recurrent receding and advancing glaciation led to their demise. Recent research has suggested that rapidly changing climatic conditions and volcanic eruptions may have contributed to the Neanderthals' demise. Others have argued that their anatomical distinctions were diluted through gene flow (see geneticsgenetics, BibliographySee E. Trinkaus and P. Shipman, The Neanderthals (1993); J. Shreeve, The Neandertal Enigma (1995); I. Tattersall, The Last Neanderthal (1999); S. Paabo, Neanderthal Man: In Search of Lost Genomes (2014). Neanderthal Mana fossil Paleoanthropine that lived 35,000 to 200,000 years ago, at the end of the Early Paleolithic and during the Middle Paleolithic periods. Neanderthal man inhabited Europe, Asia, and Africa. This ancient human type was named after one of the earliest archaeological finds in the Neanderthal valley. The find was made near Düsseldorf, Federal Republic of Germany, in 1856. Neanderthals occupied a transitional position between Archanthropines and human fossils of the physically modern type. The Neanderthals of Western Europe typically had a short stature (approximately 160 cm), a large brain (up to 1,700 cu cm), a skull with a well-developed brow ridge and sloping forehead, and a lower jaw without a chin protuberance. Many scholars consider the late Western European Neanderthals, who lived 35,000 to 50,000 years ago, to form a special phylogenetic branch that did not continue to develop in the course of human evolution. In support of this classification is the evidence that certain traits in Near Asian Neanderthals reached a more progressive level than in Western European Neanderthals, for example, a weakly expressed chin protuberance and a higher and rounder skull arch. These traits link Near Asian Neanderthal man to fossil humans of the physically modern type. REFERENCENesturkh, M. F. Proiskhozhdenie cheloveka, 2nd ed. Moscow, 1970.V. P. IAKIMOV Neanderthal man[nē′an·dər‚täl ′man]Neanderthal manNeanderthal manNeanderthalAn extinct modern Homo that lived between 230,000 and 22,000 years ago (the last known Neanderthals have been found in the Gravettian region of France). Neanderthals mostly lived in cold climates; their body proportions are similar to those of modern cold-adapted peoples: short and solid, with short limbs. Men averaged ±168 cm; their bones were thick and heavy, and showed signs of powerful muscle attachments. Neanderthals would have been quite strong by modern standards, and their skeletons show that they endured brutally hard lives.Many Neanderthal tools and weapons have been found and they were more advanced than the tools of Homo erectus. Neanderthals were hunters, and the first Homo spp known to have buried their dead—the oldest known burial site is ±100,000 years old. Neanderthal skeletons are found throughout Europe and the Middle East. The “classic” western European Neanderthals were more robust than those found elsewhere. The average brain size, about 1450 cc, is larger than that of modern humans, but this correlated with their greater bulk; the cranial cavity is longer and lower than that of modern humans, with a marked bulge at the back. Anatomy Like Homo erectus, Neanderthals had a protruding jaw and receding forehead. The chin was weak, and the midfacial area also protrudes, a feature not found in Homo erectus or Homo sapiens, which may have been an adaptation to cold. Other minor anatomic differences from modern humans include peculiarities of the shoulder blade and pubic bone. Neanderthal manthe most recently extinct species of human which lived in Europe and western Asia between c200,000 and c30,000 years ago. The species probably shared a common ancestry with Homo sapiens some 400,000 years ago. Recent research lends support to specific status and DNA analysis suggests that they did not interbreed with CRO-MAGNON MAN with whom they coexisted. Neanderthals probably evolved from the first wave of movement of Homo erectus out of Africa, Homo sapiens in Europe originating from a second such exodus.Neanderthal man
