The prehistory of Georgia is the period between the first human habitation of the territory of modern-day nation of Georgia and the time when Assyrian and Urartian, and more firmly, the Classical accounts, brought the proto-Georgian tribes into the scope of recorded history. ==Paleolithic== Humans have been living in Georgia for an extremely long time, as attested by the discoveries, in 1999 and 2002, of two ''Homo erectus'' skulls (''H. e. georgicus'') at Dmanisi in southern Georgia. The archaeological layer in which the human remains, hundreds of stone tools and numerous animal bones were unearthed is dated approximately 1.6-1.8 million years ago (since the underlying basalt lava bed yielded an age of approximately 1.8 million years). The site yields the earliest unequivocal evidence for presence of early humans outside the African continent.〔Vekua, A., Lordkipanidze, D., Rightmire, G. P., Agusti, J., Ferring, R., Maisuradze, G., et al. (2002). A new skull of early Homo from Dmanisi, Georgia. ''Science'', 297:85–9.〕 Later Lower Paleolithic Acheulian sites have been discovered in the highlands of Georgia, particularly in the caves of Kudaro (1600 m above sea level), and Tsona (2100 m). Acheulian open-air sites and find-spots are also known in other regions of Georgia, for example at the Javakheti Plateau where Acheulian handaxes were found at 2400 m above the sea level. The first uninterrupted primitive settlement on the Georgian territory dates back to the Middle Paleolithic era, more than 200,000 years ago. Sites of this period have been found in Shida Kartli, Imeretia, Abkhazia and other areas. Buffered by the Caucasus Mountains, and benefiting from the ameliorating effects of the Black Sea, the region appears to have served as a biogeographical refugium throughout the Pleistocene. These geographic features spared the Southern Caucasus from the severe climatic oscillations and allowed humans to prosper throughout much of the region for millennia.〔Bar-Yosef, Ofer; Belfer-Cohen, Anna, and Adler, Daniel S. (2006), (The Implications of the Middle-Upper Paleolithic Chronological Boundary in the Caucasus to Eurasian Prehistory ). ''Anthropologie'' XLIV/1:49-60.〕 Upper Paleolithic remains have been investigated in Devis Khvreli, Sakazhia, Sagvarjile, Dzudzuana, Gvarjilas Klde and other cave sites. A cave at Dzudzuana has yielded the earliest known dyed flax fibers that date back to 36,000 BP.〔Balter M. (2009). Clothes Make the (Hu) Man. Science,325(5946):1329. PMID 19745126〕〔Kvavadze E, Bar-Yosef O, Belfer-Cohen A, Boaretto E,Jakeli N, Matskevich Z, Meshveliani T. (2009).30,000-Year-Old Wild Flax Fibers. Science, 325(5946):1359. PMID 19745144 (Supporting Online Material )〕 At that time, the eastern area of the South Caucasus appears to have been sparsely populated in contrast to the valleys of the Rioni River and Kvirila River in western Georgia. The Paleolithic ended some 10,000-12,000 years ago to be succeeded by the Mesolithic culture. It was when the geographic medium and landscapes of the Caucasus were finally shaped as we have them today. 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「Prehistoric Georgia」の詳細全文を読む スポンサード リンク
