A study by scientists at the University of the Basque Country (UPV / EHU) and has been published in Nature has changed prehistory books , delaying about 10,000 years in the extinction of the Neanderthals.

The results suggest that the disappearance of Neanderthals in Europe and the end of the Mousterian culture makes occurred between 41,000 and 39,000 years along fields extending from the Black Sea to the Atlantic coast.

the Similarly, the study concludes that There was a rapid replacement of the Neanderthals by anatomically modern humans, and exposes a map much more complex, characterized by a biological and cultural mosaic that lasted several thousand years.

There was a rapid replacement of Neanderthals by modern humans So, the findings reveal that Neanderthals and modern humans coexisted in 2600-5400 Years in this region, which could allow cultural and genetic exchanges between the two groups. Specifically, they agreed on the same time and space between 25 and 250 generations.

This analysis was made possible after a dating precision 200 bone samples from 40 sites Archaeological from Russia to Spain.

As explained experts determine the spatial and temporal relationships between Neanderthals and early modern humans is essential to understand the underlying processes and the reasons for the disappearance of the Neanderthals.

But, technical problems have hampered the reliable dating of the period, as in samples of more than 50,000 years too little carbon-14 as preserved for traditional radiocarbon dating can provide accurate results.

To analyze the bone and stone tools of the Mousterian culture remains and other Paleolithic, which have come to be associated with Neanderthals, as Chatelperronian and Uluzziense, the research group directed by Professor of the University of Oxford Tom Higham, has employed a refined system to process the samples and date them using spectrometry accelerator mass (AMS) radiocarbon.

estimated that homo sapiens originated in Africa and came to Europe between 50,000 and 30,000 years ago .
