How and when the Americas were populated remains contentious. Using ancient modern genome-wide data, we found that ancestors of all present-day Native Americans, including Athabascans Amerindians, entered as a single migration wave from Siberia no earlier than 23 thousand years ago (ka) after more an 8000-year isolation period in Beringia. After their arrival to Americas, ancestral Americans diversified into two basal genetic branches around 13 ka, one is now dispersed across North South...
The date of the first settlement Americas remains a contentious subject. Previous claims for very early occupation at Pedra Furada in Brazil were not universally accepted (see Meltzer et al. 1994). New work rockshelter Boqueirão da and nearby open-air site Vale have however produced new evidence human extending back more than 20 000 years. argument is supported by series 14 C OSL dates, technical analysis stone tool assemblage. authors conclude that currently narrative South America will to...
Organic remains can be found in many different environments. They are the most significant source for paleoparasitological studies as well other paleoecological reconstruction. Preserved from driest to moistest conditions. help us understand past and present diseases therefore contribute understanding evolution of human sociality, biology, behavior. In this paper, scope surviving evidence will briefly surveyed, great variety ways it has been preserved environments discussed. This is done...
Sítio do Meio, discovered in the 1990s, showed a sedimentary sequence clearly composed of two sets deposits separated by zone large rockfall from massive collapse shelter's overhang. The bottom set, slightly more than 60 cm thick, was trapped between bedrock (upon which it rested) and lower part roof fall (reaching 1 m excavation area), yielded some charcoal without other archaeological material. New excavations, however, have revealed presence artifacts, additional charcoal, an alignment...
Abstract The paper gives a review of archaeological work in the south‐eastern part Piaui State, Brazil, with particular reference to chronology and geological history rocksheiter sites, such as Toca do Boqueiräo at Pedra Furada, Sitio Meio. article analyses critiques early dates South America, notes bias towards rejection dates, additional documentation State. It concludes by urging that new consensus be developed among archaeologists studying American sites.
Current archaeological paradigm proposes that the first peopling of Americas does not exceed Last Glacial Maximum period. In this context, acceptance anthropogenic character earliest stone artefacts generally rests on presence projectile points considered no more as typocentric but typognomonic, since it allows, by itself, to certify human other associated artefacts. words, without presence, nothing is certain. Archaeological research at Piauí (Brazil) attests a Pleistocene between 41 and 14...
The question of when the first humans arrived in New World has been a bone contention for several decades. Similarly, age rock paintings heatedly debated. Settlements Serra da Capivara National Park have dated to between 5 kyr and >50 kyr, which is far older than Clovis barrier. Moreover, calcite formation on rock-wall painting rockshelter yielded thermoluminescence (TL) electron paramagnetic resonance (EPR) ages 35 BP (Watanabe et al. 2003). In an attempt contribute this ongoing debate,...
This paper presents an osteobiographic analysis of a single skeleton found in small rock shelter known as Toca dos Coqueiros, Piauí, Brazil. find is interest because exceptionally old radiocarbon date associated with it. The (11,060 BP) was obtained from charcoal directly the skeleton. interesting rarity studies skeletons such antiquity. Despite existence two projectile points association burial, morphological and molecular analyses demonstrated that this female. She about 35-45 years age at...
RÉSUMÉ La Toca do Boqueirâo Sitio da Pedra Furada, dans la région de Sâo Raimundo Nonato (Piaui, Brésil), présente un remplissage épais 5 m avec trois niveaux pleistocenes et holocènes. L'acidité du sédiment n'a pas permis conservation fossiles mais plus 7 000 artefacts, dont 600 paléolithiques, environ 160 structures correspondant pour plupart à des foyers y ont été découverts. Cinquante-quatre datations au radiocarbone, 32 pleistocenes, réalisées par laboratoires différents partir charbons...
Abstract The Serra da Capivara National Park in northeastern Brazil is one of the richest archaeological regions South America. Nonetheless, so far only two paleoindian skeletons have been exhumed from local rockshelters. oldest (9870 ± 50 BP; CAL 11060 50), uncovered Toca dos Coqueiros and known as “Zuzu,” represents a rare opportunity to explore biological relationships groups living Brazil. As previously demonstrated, Central America Paleoindians present skull morphology distinct found...
The archaeological evidence of the Pedra Furada rock-shelter (northeastern Brazil), showing a long sequence dated layers from 50,000 years b.p., was questioned in paper presented by Meltzer, Adovasio & Dillehay, who visited region at end 1993, volume 68 ANTIQUITY (1994). This presents reply team directly involved research programme this key area American prehistory.
