Neandertals on the Iberian Peninsula experienced extinction and change before the arrival of Homo sapiens, according to a study published March 30, 2022 in the journal Nature. PLOS SOMEONE by Joseba Rios-Garaizar of the Archaeological Museum of Bilbao, Spain and colleagues.

The Neandertals disappeared about 40,000 years ago, but the exact details of their extinction are unclear. To explain the situation, it is necessary to find out how the Neandertal population changed during their last millennium. In this study, the researchers looked at the provision of an artificial organism called the Châtelperronian, which is thought to be unique to certain populations of Neandertals in France and the Iberian Peninsula.

Researchers examined over 5,000 remains of Châtelperronian artifacts from a site called Aranbaltza II in Barrika, on the Northern Iberian Peninsula, about 45,500 years ago. Comparing this system with other related Neandertal systems, they wrote that the Châtelperronian system was not covered at the time with the older Neandertal technologies in this country, assuming that the devices were not built. Châtelperronian production from Iberian technology in the past, but emerged elsewhere before moving to the country. . They also found that Châtelperronian producers were earlier known than the first Homo sapiens producers on the Iberian Peninsula.

Based on this evidence, the authors believe that the ancient Neandertal Iberians were lost, taking their form of tools with them, and were replaced by other Neandertal groups using Châtelperronian tools, probably migrating from France, and these numbers were replaced by Homo sapiens. The researchers believe that these patterns of local Neandertal depletion and transformation will be an important area of ​​study in the future, as they are likely to be important in the decline and transformation of the Neandertal region. the last death of Neandertals.

The authors add: “Neandertals with Châtelperronian technology inhabited the Northern Iberian Peninsula ca. 43,000 years ago. This land was not inhabited at that time, after the first disappearance of local Neandertal settlements, with their Mousterian technology. ”
