Decoding palaeolithic hand stencils: age and sex identification through geometric morphometrics

Abstract

This study pioneers the application of geometric morphometrics to Palaeolithic hand stencils, offering new insights into the problematics of classic rock art using innovative methodology. Employing a triple approach encompassing contemporary, experimental, and archaeological populations, the research achieves a precise estimation of age and biological sex through hand morphometry, enhancing our anthropometric understanding of the individuals whose hands were stencilled. The results of the analysis of the archaeological sample reveals a notable presence of sub-adults, indicating children’s participation in the creation of hand stencils. The findings also suggest a balanced, mixed participation between sexes across age groups and cave locations, reflecting cohesive social behaviour among Upper Palaeolithic human groups. Statistical analysis indicates that finger width in the Palaeolithic population is larger than in the modern sample, possibly due to a more active lifestyle. Most importantly, the study demonstrates the methodology’s repeatability across various chronologies and geographies, especially in well-preserved samples, underscoring its applicability worldwide. Overall, this research represents a significant methodological advancement in our ability to understand Palaeolithic rock art, shedding light on lifestyle and cultural dynamics of hunter-gatherer societies.
