A cave dweller, or troglodyte, is a human being who inhabits a cave or the area beneath the overhanging rocks of a cliff. == Prehistory == Some prehistoric humans were cave dwellers, but most were not. (''See'' "Homo" and "Human evolution".) Such early cave dwellers, and other prehistoric peoples, are also called ''cave men'' (the term also has other meanings). Despite the name, only a small portion of humanity has ever dwelt in caves: caves are rare across most of the world; most caves are dark, cold, and damp; other cave inhabitants, such as bears and cave bears, cave lions, and cave hyenas, also have made caves inhospitable for people. The Grotte du Vallonnet, a cave in the French Riviera, was used by people approximately one million years ago. Although stone tools and the remains of eaten animals have been found in the cave, there is no indication that people dwelt in it. Since about 750,000 years ago, the Zhoukoudian cave system, in Beijing, China, has been inhabited by various species of human being, including Peking Man (''Homo erectus pekinensis'') and modern humans (''Homo sapiens sapiens''). Starting about 170,000 years ago, some ''Homo sapiens'' lived in some cave systems in what is now South Africa, such as Pinnacle Point and Diepkloof Rock Shelter. Caves were the ideal place to shelter from the midday sun in the equatorial regions. The stable temperatures of caves provided a cool habitat in summers and a warm, dry shelter in the winter. Approximately 100,000 years ago, some Neanderthal humans dwelt in caves in Europe and western Asia. Caves there also were inhabited by some Cro-Magnons from about 35,000 years ago until approximately 8,000 B.C. Both species built shelters, including tents, at the mouths of caves and used the caves’ dark interiors for ceremonies. The Cro-Magnon people also made representational paintings on cave walls.〔Butzer, Karl W. "Cave dwellers", ''The World Book Encyclopedia'', Vol. 3, p. 245. World Book, Inc.: Chicago, 1983.

They made the earliest paint workshop now known, but apparently did not dwell in the caves.〔"(In African Cave, Signs of an Ancient Paint Factory )", ''The New York Times'', October 13, 2011.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cave dweller」の詳細全文を読む スポンサード リンク
