A origem do homem americano vista a partir da América do Sul: uma ou duas migrações?

Abstract: RESUMO: Até meados da década de 1990, predominava na literatura especializada que o Novo Mundo teria sido colonizado por três levas distintas, todas com origem no nordeste asiático. Na segunda metade da década, dois modelos alternativos começaram a desfrutar de grande popularidade entre a comunidade acadêmica internacional. O primeiro deles, denominado "Modelo dos Dois Componentes Biológicos Principais", baseado na variabilidade craniométrica de populações nativas americanas extintas, sugere que a América teri… Show more

“…The first of them explains that these two different morphologies already arrived distinct in the New World, that is, two different populations from the Asiatic continent arrived in America between the final phase of the Pleistocene age and the beginning of the Holocene. The second sustains that Paleoamerican morphology (older) originated the Amerindian morphology (newer) by means of a local microevolutionary process, notably, genetic drift 7 . The excavation of the archaeological site of "Furna do Estrago" in "Brejo da Madre de Deus" city, Agreste of Pernambuco State, began in 1983.…”

“…The second group was characterized by short and wide neurocraniums, with high faces (including nose and orbits). They lived during the Archaic period (less than 8,000 years ago) 7 . Two distinct scenarios have been raised to explain the morphological duality of the ancient cranium's form from South America.…”

“…8 Considerando filogenia como a história genealógica de um grupo, onde as relações "ancestral x descendente" são hipotéticas (O'Brien & Lyman, 2005 (Neves et al, 2007;Neves et al, 2013 (Fogaça, 2001;Fogaça & Lourdeau, 2008; & Beltrão, 1975). Na última década a mesma região foi alvo de pesquisas arqueológica e paleontológicas (Neves et al, 2008;Strauss, 2011 (Schmitz et al,1989).…”

“…De acordo com esse modelo, teriam entrado duas populações biologicamente diferenciadas no continente americano, uma associada morfologicamente às populações australo-melanésicas e africanas atuias e outra associada às populações mongolóides. Desde a proposta do modelo, diversos trabalhos produzidos por Neves e colaboradores vêem corroborando seus primeiros achados e consequentemente dando suporte ao modelo proposto (Munford et al, 1995;Neves et al, 1996;Neves et al, 1999a;Neves et al, 1999b;Neves et al, 1999c;Neves et al, 1999d;Neves et al, 1999e;Neves & Blum, 1998;Blum & Neves, 1999;Neves & Blum, 2000;Blum et al, 2001;Neves & Blum, 2002;Neves et al, 2003;Hubbe et al, 2004;Neves & Atuí, 2004;Neves et al, 2004a;Neves et al, 2004b;Pucciarelli et al, 2006;Hubbe et al, 2007;Neves et al, 2007a;Neves et al, 2007b;Pucciarelli et al, 2003Pucciarelli et al, , 2008.…”
