Blombos Cave is an archaeological site located in Blombosfontein Nature Reserve, about 300 km east of Cape Town on the Southern Cape coastline, South Africa. The cave contains Middle Stone Age deposits currently dated at between c. 100,000 and 70,000 years before present (BP), and a Late Stone Age sequence dated at between 2000 and 300 years BP.〔Tribolo, C., et al.

(2008) Holocene prehistory of the Southern Cape, South Africa : excavations at Blombos Cave and the Blombosfontein Nature Reserve, Oxford, England, Archaeopress.〕 The excavations at Blombos Cave have yielded important new information on the behavioural evolution of our species, ''Homo sapiens''. The archaeological record from this cave site has been central in the ongoing debate on the cognitive and cultural origin of early humans and to the current understanding of when and where key behavioural innovations emerged among ''Homo sapiens'' in southern Africa during the Late Pleistocene.〔McBrearty, Sally & Brooks, Alison S.

The most informative archaeological material from Blombos Cave includes engraved ochre,〔Henshilwood, Christopher S., d'Errico, F. & Watts, I.

(2011) Taphonomic analysis of the Middle Stone Age larger mammal faunal assemblage from Blombos Cave, southern Cape, South Africa. Journal of Human Evolution, 60, 746-767.〕 These findings, together with subsequent re-analysis and excavation of other Middle Stone Age sites in southern Africa, have resulted in a paradigm shift with regards to our understanding of the timing and location of the development of modern human behaviour. On 29 May 2015 Heritage Western Cape formally protected the site as a provincial heritage site.〔Provincial Notice 163/2015, Province of the Western Cape Provincial Gazette, No 739, Cape Town: 29 May 2015〕 ==Excavation history and research context== Blombos Cave was first excavated in 1991–1992 as a part of Professor Christopher S. Henshilwood’s (1995) doctoral thesis.〔Henshilwood, Christopher S. (1995) Holocene archaeology of the coastal Garcia State Forest, southern Cape, South Africa., Cambridge.〕 at the University of Cambridge: ''Holocene archaeology of the coastal Garcia State Forest, southern Cape, South Africa.'' Blombos Cave was originally one of nine Holocene Later Stone Age sites that Henshilwood excavated and it was first given the acronym GSF8 (Garcia State Forest, site no. 8). In 1997 GSF8 was renamed Blombos Cave and given its current acronym: BBC.〔 From 1999 to 2011 in total ten field seasons, each six weeks long, have been carried out at the cave site. From the initial excavations conducted in the early 1990s, the Blombos Cave project has adopted and established new and innovative research agendas in the study of southern African prehistory. While Henshilwood’s initial, doctoral research was directed towards the more recent Later Stone Age occupation levels, the focus since 1997 has been on the Middle Stone Age sequence. The Blombos Cave project has since then developed academically, economically and administratively; from being a local and small-scale test excavation to becoming an international, full scale, high-technological archaeological project. In 2010–2015 the cave site is the focus of the multi-disciplinary, pan-continental research program (TRACSYMBOLS ). The (TRACSYMBOLS ) project is led by Professor Christopher S. Henshilwood based at the (Department of Archaeology, History, Cultural Studies and Religion ) at the (University of Bergen ) and the (University of the Witwatersrand ), South Africa, together with Professor Francesco d’Errico from the (University of Bordeaux 1 ), France. The aim of (TRACSYMBOLS ) project is to examine how key behavioural innovations emerged among ''Homo sapiens'' and ''Homo neanderthalensis'' in southern Africa and Europe respectively, and to explore whether and how environmental variability influenced this development between 180,000 – 25,000 years ago; primarily by combining archaeological results, original multi‐proxy palaeoenvironmental data and climatic simulations for two continents. 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「Blombos Cave」の詳細全文を読む スポンサード リンク
