With America and its past before calling itself that, instead of Colombia or Columbia, the doubts, the statements that contradict and a continuing doubt about their origins follow.As we all know, Colon was not the first foreigner to arrive at this continent, but neither were the Vikings, nor the Chinese, although perhaps if the Polynesians.Something similar happens with their original settlement, with whom they were the first inhabitants of the New World that, for several theories, has not turned out to be so new.
The traditional theory of occupation of the continent
The classic and most accepted theory until the beginning of the new millennium is that human beings entered America through of the Bering Strait , the point where Alaska and Asia are closest (80km) and that in the last glaciation I have the land exposed and as a bridge between both continents for a sufficiently long period as to allow the passage of several waves of human groups from Siberia and eastern Asia .
The first of these waves would have occurred 14,000 years ago, and the Inuit or Eskimos, current occupants of both ends of the Bering Strait, arrived with the last migration.
22,000 years before
However, this theory has been questioned several times by archaeologists and historians who point to an earlier arrival, 20 or 30,000 years ago, and from other places, like the European theory.This, which emerged in the twenties of the last century and resumed in the sixties and again in the late nineties, proposed an occupation of America 10,000 years before migrating Bering ions, and from Europe instead of Asia.The villagers would have been Europeans from the Upper Paleolithic who came across the Atlantic.
DNA has the word
European theory has been completely ruled out in recent years because the evidence was very weak and thanks to advances in genetics and the establishment of a DNA map.
Research in This field suggests that the classical population theory would be correct: the first Americans arrived from Asia approximately 15,000 years ago (studies carried out between 2007 and 2013).
More recently, in 2014, the results of a DNA study conducted in the remains of a child of the Clovis culture, still considered by many researchers as the oldest culture in America, and whose archeological site Gico is in North America, they showed that it was linked to the original inhabitants of Central America and South America, which has served as support for the theory that the continent was colonized in successive migratory waves: the towns of Central and South America would derive of the first waves, while those from the north would descend from more recent waves.
And if not Were humans the first to arrive in America?
We're not talking about aliens or the Palenque astronaut , but the possibility that predecessors of homo sapiens , such as homo erectus , arrived before the New World.
In this direction point discoveries of archaeological sites in Brazil and Canada, where stone lacquers have been found in strata that could date from 200 and 300,000 years ago.Let's not forget that homo sapiens It exists as such for 150,000 years, and I am not supposed to leave Africa until 70,000 years ago or less.These old dates are still under discussion and have not been fully accepted.
With America, every new discovery only muddies the history of those who were its first inhabitants, but it is still a fascinating story with a long way to go.
