An article in the journal “Nature” reports a genetic study on some human beings who lived in Bacho Kiro Cave, in today’s Bulgaria, the most ancient modern humans dated so far with reasonable certainty. A team of researchers managed to obtain DNA from the available bones, which was analyzed at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. The comparison with the genetic characteristics of today’s European and Asian populations shows how those ancient humans spread and that they had some Neanderthal ancestors.
