Ferramentas de pedra, fogueiras and ornaments recém-encontos no Mato Grosso e dating from quase 30 thousand years têm given combustível to a historical discussion in modern archeology: to date of chegada two human beings às Americas.
There are different theories, from what I affirm that or ocorreu event about 12 thousand years ago I apostam in 100 thousand years or more.
A descoberta recente foi feita not archaeological site of Santa Elina, 80 km from Cuiabá. The archaeologists responsáveis pelas escavações, Denis Vialou and Águeda Vilhena Vialou, the National Museum of the Natural History of França, affirm that this Brazilian region was inhabited at least 27,000 years ago.
"Uma prova é a presence of more than 300 objects of lasra stone, with serrations and retouching, which could only be feitos pela mão do homem," says Águeda, who has been excavating the Serra das Araras region since 1995.
Outra prova da presença humana, second ela, são remains of fogueiras.
Or material found foi dated by three different methods, wrapping from radiocarbon 14 até otic luminescência.
Second Águeda, or site of Santa Elina traz uma tripla raridade: "A primerira é that pleistocene human occupations (between 2,588 milhões and 11,7 thousand years ago) are rare and as a result the only local descoberto not center of the sul- American."
A second e a terceira raridades dizem respects the found adornments: some foram feitos com ossos de preguiças-gigante do gênero Glossotherium, já extinct.
"It is the first case in Brazil of a perfect association of home with an extinct megafauna," explains Ela. "He has to make symbolic objects like megafauna, transforming them into ornaments."
Discuss from Colombo
A discussão about the date of the Humanity of the Americas in the early years of Cristóvão Colombo, when it disembarked not in the Caribbean on October 12, 1492.
He was welcomed by Taino hairs, a friendly man, who navigated Genoa to serve Espanha Achou who fossem Indians, but he was convinced that he had stayed in India and stayed with this conviction attached to death.
O descobridor da América não sabia, more sua chegada ao continent marcou, na verdade, or reencontro of duas linhagens evolutivas of Homo sapiens, who were separated from each other less than 50 thousand years ago: to their own, europeia, and to two first Americans, Mongoloids, pretending to be Asian povos.
From então, persiste or mistério: como e quando povos found by Colombo chegaram às Américas?
Theories não faltam. A more resistant and older model known in English as Clovis-first (Clóvis-primeiro). Deve seu nome a um archaeological site called assim, descoberto em 1939, no Novo Mexico, United States.
Not local, foram found artifacts of stone pedra, dating from 11,4 thousand years. The second theory, defended mainly by the American archeological community, has lasted about 12,000 years.
Já or chamado "modelo das três migrações", suggested in 1983 by Christy Turner, was based on an example of a variety of dentifrice, which ended with three migratory caves from Sibéria for America.
In the first place, 11,000 years ago, the country originated all of the Indies of Central America and South America, and two native North American natives. The second one was settled 9 thousand years ago and the ancestral Indians of Apaches and Navajos, above the Pacific coast of the United States and Canada. A last serious be more recent, has 4 thousand years, and compost hairs ancestrais two esquimós e povos aleutas (no Arctic Circle).
Brazilian Scientists also have their theories of Occupation of the Americas.
Uma delas foi desenvolvida hair biologist and anthropologist Walter Alves Neves and hair geographer Luís Beethoven Piló, both from the Universidade de São Paulo (USP). Eles propõem that you first Americans chegaram ao continent em duas migratórias cams, first 14 thousand years ago on the second day 11 thousand, came from Asia hair Bering.
According to comel, at first it would be a compost for a população com traços semelhante two African and Australian aborigines. A second era of Mongoloids, semelhantes Asian years and American Indians atuais.
A second theory foi proposta by three Brazilian geneticists and an Argentinean anthropologist, defending that houve barely uma migratória cam, has 18 thousand years.
Before that, you ancested two migrants who had been "imprisoned" in Beríngia, a region that joined or north to northeast of Sibéria and that was never submerged (it was the apex of the last glacial period and was 120 meters below sea level).
"Essa população abrigava from similar African years to similar ones as índios atuais", explains Maria Cátira Bortolini, from the Federal University of Rio Grande do Sul, a member
