6000 years ago, a population without known genetic descent arrived in Colombia. No one knows what happened to him.
The analysis of the DNA of 21 sets of human remains in Colombia allowed a discovery of a new population that had been established in the region 6000 years ago.
Collected in five places in the Altiplano Plateau in the center of Colombia, remains have a genetics that do not relate to any modern descendant. And may belong to some of the first colonizers of South America.
“No we achieved find descendants of these first hunter–recletory the plains Colombian — os genes no they were transmitted“, it says a anthropologist Kim–Louise Cotton, and University of Tübingen, na Germany, quoted by . “This means that in the area around Bogota there was a complete exchange of the population.”
It seems that these people remained in place until Arrival of the European settlers in the 16th century. The new published in Science Advances It also explains that this group was replaced 2000 years ago by populations that spoke chibchanous languages and have known genetic connections with modern groups in Central America.
“The fact that the genetic traces of the original population disappear completely It is unusualespecially in South America, ”geneticist Andrea Casas-Vargas, from the National University of Colombia.
“These are the first ancient human genomes of Colombia to be published,” says anthropologist Cosimo Posth of the University of Tübingen. What happened to them? Conflict or disease These are common causes for extinction of populations – future studies can give more details.
