Oldest Neanderthal Remains Found In Northern Spain
One of the oldest Neanderthal remains to have been discovered have been found in the Basque Country. Scientists have dated the human remains to be approximately 100,000 years old.
Researchers from the International Institute for Prehistoric Research of Cantabria (IIIPC) made their discovery at the Axlor site in Dima, Biscay province.
Children and a young adult from the past
The excavated remains include teeth from two children between the ages of 10 and 12 and a young adult. According to Jesús González-Urquijo, the director of the IIIPC, these remains represent “the oldest known evidence in the north of the Iberian Peninsula.” The teeth of the adult show specific anatomical features of Neanderthal populations in the Iberian Peninsula. This points to a possibly unique evolution within this area.
Crucial moment in European demographic history
The period around 100,000 years ago was crucial in European demographic history. This preceded the interactions between Neanderthals and modern humans and the Neanderthal expansion into Central Asia. The limited evidence available so far, supplemented by Axlor’s results, suggests a remarkable continuity of Neanderthal population in Europe from this early period of the Late Pleistocene.
New research methods
The research introduces a new methodology for taxonomic classification. Subtle differences in tooth structure between Neanderthals and modern humans are used. Using geometric morphometrics, a method that allows for more robust comparisons, the researchers were able to place Axlor’s teeth within the variability typical of Neanderthal populations.
New information about Neanderthal societies
Axlor’s Neanderthal teeth were discovered during archaeological excavations led by the IIIPC, in collaboration with international experts. This research is part of the NeandertalHD project. This focuses on studying the capabilities and behaviours of Neanderthal societies. The historical dynamics in Southwestern Europe between 100,000 and 40,000 years ago are also examined. Finally, there is a focus on the relationship between environmental changes and historical developments.
