Science Frontiers ONLINE No. 108: Nov-Dec 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Deflating a paradigm: brazil's pedra furada The paradigm. The New World was peopled from Asia by migration across the Bering Land Bridge about 12,000 years ago, or perhaps a wee earlier. The Pedra Furada site has been dated at 50,000 BP by N. Guidon and her team of archeologists. This challenge to the dominant paradigm is powerful and unambiguous ... Picking up the gauntlet, several more-conservative archeologists visited the Brazilian site and penned a blistering critique in Antiquity. (Ref. 1) Their major contention was that the 500+ supposedly human-made stone "artifacts" collected by Guidon's team are actually "geofacts"; that is, they were chipped and flaked naturally as rocks fell one upon the other from nearby cliffs. We discussed this problem in some detail in SF#105. Several other reservations about the Pedra Furada work are also offered in Ref ... 1. The reaction of Guidon et al to the Antiquity paper was thunderous to say the least. It revealed the depth of the chasm separating archeologists on the date of human occupation of the New World as well as internecine politics in archeology. (Ref. 2) Guidon et al flung two serious charges at the authors of the first Antiquity paper: (1 ) They had their facts all wrong; and (2 ) Their objectivity was distorted by their loyalty to the aforestated paradigm. Not withholding any punches, N. ...

... Science Frontiers ONLINE No. 87: May-Jun 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The 50,000-year-old americans of pedra furada French archeologists (not American) have established to the satisfaction of most European archeologists (not American) that humans were present in Brazil at least 50,000 years ago. F. Parenti, with N. Guidon, presented their data at a recent Paris meeting. The main site studied was the sandstone rock ... of Pedra Furada, which is one of several hundred painted rock shelters discovered in northeastern Brazil. Guidon began her work in 1978; Parenti, in 1984. The fourvolume, 7-kilogram report (actually Parenti's doctoral thesis) concentrates on three lines of evidence: A coherent series of 54 radiocarbon dates ranging from 5,000 to 50,000 years. Crudely flaked stones, some 6,000 of which are deemed of human manufacture, even when the most stringent criteria are applied. Many of these came from ... strata 50,000 years old or older. Some 50 Pleistocene "structures" consisting of artificial arrangements of stones, some burned, some accompanied by charcoal. These are likely ancient hearths. (Bahn, Paul G.; "50,000-Year-Old Americans of Pedra Furada," Nature, 362:114, 1993.) Comment. With the Brazil and Chile (Monte Verde) sites looking more and more convincing, it is reasonable to ask why even older sites have not been found in North America ...

... Oct 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Humans in the americas 32,000 years ago?The following abstract is from Nature. Ir relates to one of the most controversial digs in the New World: Pedra Furada, in Brazil. "The view that man did not arrive on the American continent before the last glaciation has been supported by the fact that until now the known and dated archaeological sites have not been of very great antiquity. But now we report radiocarbon ... from a Brazilian site which establish that early man was living in South America at least 32,000 years ago. These new findings come from the large painted rock shelter of Boqueirao do Sitio da Pedra Furada, the walls and ceiling of which are decorated with a rich set of prehistoric paintings. We have excavated a sequence containing abundant lithic industry and well-structured hearths at all levels. Carbon-14 dates from charcoal establish a continuous chronology indicating human occupation from 6,160 130 to 32, 160 100 years BP. ... date of 17,000 400 BP, obtained from charcoal found in a level with fragments of a pictograph fallen from the walls, testifies to the antiquity of rupestral art in the region of Brazil." (Guidon, N., and Delibrias, G.; "Carbon-14 Dates Point to Man in the Americas 32,000 Years Ago," Nature, 321: 769, 1986.) Comment. The Nature article just abstracted and other reports of the Brazilian discovery do not mention or discount the considerable evidence ...

... humans at least as long ago as 45,000 years. The 'quantity, diversity and preservation' of materials at the sites, she said, shoud lead to 'profound changes in the knowledge of prehistoric America.'" The Brazilian rock shelters, particularly Pedra Furada, boast elaborate paintings, fireplaces, tools, and butchered-animal bones. (See SF#54 from 1987.) Although some American archeologists have edged back to 13,000 BP, others are still stonewalling at 12,000 BP or less ... Actually, the debate has become unscientific on occasion, as revealed by R. Bonnichson, of the University of Maine. "' Numerous metritorious grant proposals have been rejected because their goals and objectives were incompatible with entrenched academic opinion,' he said. 'At least five South American archeologists admitted that they were suppressing pre12,000-year-old data out of the fear that their funds would be cut off by American colleagues who endorse the short-chronology school of thought.'" (Wilford, John Noble; ... barrier seems to be collapsing. The turning point may have occurred at a recent meeting at the University of Maine's Center for the Study of the First Americans. The skeptics were bombarded by radiocarbon dates, tools, hearths, and bones from the Monte Verde site in Chile. Some previouslyunbelieving archeologists are now ready to admit dates around 13,000 BP for Monte Verde. (Lewin, Roger; "Skepticism Fades over Pre-Clovis Man," Science, 244:1140, 1989.) Comment.
