A recent discovery in the mountainous area of Malargüe has impacted the world of archeology. Scientists at the Natural History Museum of San Rafael managed Dating (set antiquity) a settlement of more than 5,500 years. What is new is that in this period the presence of great civilizations of the American continent is almost nonexistent. The research team consists of doctors Gustavo Neme, Adolfo Gil, licensees Carina Llanos, Miguel and Alejandra Guerci Giardina, and scholars from other countries and provinces. Practitioners explained that there are abundant data and discoveries between 10,000 and 8,000 years before the present and 4000 to recent civilizations, but they said something happened between these periods (8000 and 4000) because there are virtually no data in much of America. Humberto Lagiglia years ago had found some human bones in the area and now we find other vestiges of a primitive society in the area. Samples of all this is what we are revealed in this special period, they detailed. The place is in a mountainous area and close to streams and Rubbish Disposal. One Atuel basin and the other in Salado. A few weeks ago we returned the results of studies of carbon 14 different samples sent to the laboratories of the University of Arizona AMS facilitis. Studies have made there for practical reasons, explained. At the University of La Plata are also performed but more material is needed. In the United States, thanks to another method -acelerador masses, you can get the same result with a small amount of sample, grams only. Taking up the story of the discovery, they emphasized that the site remains found arrowheads and other stones that reveal that these groups of people were there. There are traces that detect brought material for building elements Peteroa volcano area and the Pehuenche, which are approximately 100 kilometers in a straight line in the study site. But these professionals not only manage to detect traces of settlements but begin to put together a puzzle that allows them to determine the type of companies that had at the time, how they lived, what they ate and, among many other things, what the weather was and both flora and fauna which it developed. In this case they have already detected some species of flora and fauna: for example, spread seeds of wild grass (pehuenches astragalus) a toxic plant that does not even know what it was used. Calafate (empetrifolia) plant whose fruit is edible and today it is used to make jellies; alfirelillo, forage and molle disturbed environments (schinus polygamus) used to produce alcoholic beverages such as houses. Among the animals they hunted these Paleoindian there rheas and guanacos. The previous inhabitants hunted Megatherium (giant sloth), gliptodontes (armadillos large) and the American horse, which was similar to the present but smaller horse animal. None of these human concentrations are known, any domesticated animal. As they hunted for eating, reported. These companies, they said, were composed entirely separate families. They moved very simply without bosses or leaders. In some very special opportunities such as war or hunting seasons or weather crises arose a person who organized, but no one was obliged to obey. Note that these achievements will advance greatly with the global research carried out over the period. Scientists sanrafaelino museum amid enthusiasm, claim that these studies could establish, together with other scientists working across America in search of data, what happened in those times. Theories Explained handled several theories. One is that there was a great aridity; another tells of the fall of meteorites and a third claims that could be a time of great volcanic activity (as shown in Payunia). The truth is that the human presence for some reason became very scarce in the same areas where they have found remains of great civilizations of earlier and later times. Scientists revealed that these and further studies will be presented at a meeting of anthropologists to be made in Canada in March 2008.
