Researchers from the Universitat Autònoma de Barcelona have confirmed continuous human occupation in the Pyrenees mountains for several thousand years [1].
This finding provides a detailed chronological map of how early humans adapted to extreme environments. By establishing a consistent timeline of presence in high-altitude regions, the study helps archaeologists understand the migration and survival patterns of prehistoric populations.
The team focused their research on the Aigüestortes i Estany de Sant Maurici National Park [1]. They specifically analyzed archaeological sites located at altitudes of more than 2,000 meters, or 6,562 feet [1].
To achieve these results, the researchers created an open database consisting of 124 carbon-14-dated samples [1]. This data allowed the team to develop a chronological sequence for 380 different archaeological sites within the park [1].
While some reports suggest this continuous occupation spans 10,000 years [2], the primary research data describes the period as several thousand years [1]. The use of radiocarbon dating allows scientists to pinpoint when organic materials were last alive, providing a window into the timing of human activity at these peaks.
The project sought to establish a rigorous timeline of human presence in the high-altitude Pyrenees [1]. By synthesizing existing data into a single open-access database, the UAB researchers have created a tool that other scientists can use to verify and expand upon these findings.
“Continuous human occupation in the Pyrenees mountains for several thousand years”
The creation of an open database for these 380 sites shifts the research from isolated discoveries to a systemic understanding of high-altitude habitation. By proving that humans consistently returned to or lived in areas above 2,000 meters, the study suggests that prehistoric populations possessed sophisticated survival strategies and a deep reliance on mountain ecosystems over millennia.
