Le plus ancien peuplement de l'Amérique : le Paléolithique du Nordeste brésilien

Abstract: RÉSUMÉ La Toca do Boqueirâo do Sitio da Pedra Furada, dans la région de Sâo Raimundo Nonato (Piaui, Brésil), présente un remplissage épais de 5 m avec trois niveaux pleistocenes et trois holocènes. L'acidité du sédiment n'a pas permis la conservation de fossiles mais plus de 7 000 artefacts, dont 600 paléolithiques, et environ 160 structures correspondant pour la plupart à des foyers y ont été découverts. Cinquante-quatre datations au radiocarbone, dont 32 pleistocenes, ont été réalisées par trois laboratoires… Show more

“…However, the current distribution of group‐1 alleles in NEAs cannot be simply explained by recent gene flow with populations arriving in the region in the past 2,000 years (e.g., from migrations along the Silk Road), because a number of these alleles (e.g., A*01:01, B*27:02, B*27:05, C*06:02, and DRB1*08:02) are also observed in Amerindian populations (which is not the case with group‐2 alleles). Paleontological and/or archeological data indicate that human colonization of the Americas occurred at least 16,500 years ago (Goebel et al,2008) and possibly much earlier (Guidon et al,1994,1996), thus favoring the hypothesis of an ancient expansion of these alleles.…”

“…Late Pleistocene and Early Holocene human settlements are widespread on the continent, although their number is quite limited (Barnosky and Lindsey, 2010). Some sites have been recognised along the western coast of Chile (Núñez et al, 1994), in the extreme southern part of the continent (Massone, 1996), in the central Andes (Dillehay et al, 1992), in central-northern areas of Argentina (Nami, 1987;Martinez, 1997;Borrero et al, 1998;Long et al, 1998;Politis and Gutiérrez, 1998;Grosjean et al, 2005;Rodriguez, 2005;Yacobaccio and Morales, 2005), in the northwestern (Correal and Van der Hammen, 2003), northeastern (Guérin et al, 1993;Guidon et al, 1994) and central-southern regions of Brazil (Miller, 1987;Schmitz, 1987;Kipnis, 1998;Prous and Fogaça, 1999;Neves et al, 2004;Araujo et al, 2005), in northern Venezuela (Ochsenius and Gruhn, 1979) and along the Ecuadorian coast (Ficcarelli et al, 2003).…”

“…The sertão includes the caatinga or scrub forest region encompassing parts of the current States of Piauí, Ceará, Rio Grande do Norte, Alagoas, Paraíba, Pernambuco, Sergipe, Bahia, and Minas Gerais. In the sertão, the cultural tradition of Northeast Brazil was documented by burials, rock art, and the presence of associated artifacts in various well-dated locations (Guidon et al, 1994;Martin, 1996;Lessa & Guidon, 2002).…”
