When skulls speak
The image skull has given more surprises than Washington University Researchers expected. At the site discovered on the banks of the Talgua River in South America was the photo and another 200 head bones awaiting the arrival of the researchers. According to the first study, they are the oldest remains of South America and will have great value to investigate civilizations hitherto unknown.
The greatest surprise has been found by the tools that accompany the skulls: Although they are prior to the development of the Mayan civilization, they have shown that they had a more solid social structure than their own. To confirm this hypothesis, a protein analysis of the representative traces of the two human groups has been performed and the conclusions obtained have shown that the previous theories are wrong.
