Neandertals extinction around 40,000 years ago, but many things of their extinction remain unknow. To clarify the situation, Neanderthal tool study may help us. Neandertal populations were changing during their final millennia. In this study, researchers examined the distribution of a tool complex known as the Châtelperronian.
The Scientists checked over 5,000 remains of Châtelperronian tools from a site called Aranbaltza II in Barrika, in the Northern Iberian Peninsula, dating to around 45,500 years ago. Scientists compared the tools of Homo and Neandertal. Neandertal populations in the Iberian Peninsula were experiencing extinction and replacement even before Homo sapiens arrived
Revealing the cause of extinction
Accounding to this proof, the authors suggest that older Iberian Neandertal populations extinction, taking their tool styles with them, and were replaced by diverse Neandertal human using Châtelperronian tools. The researchers think that these patterns of local Neandertal extinction and replacement will be an important case of future study. Cause they played an important role in doom.
Neandertals with Châtelperronian technology occupied the Northern Iberian Peninsula ca. 43,000 years ago. At that time the territory was uninhabited, following the earlier disappearance of local Neandertal groups, along with their Mousterian technology, said The authors.
Such local patterns of extinction and replacement could help researchers understand why all Neanderthals eventually died out.
