Indigenous populations of the Big Ice Wall, have developed unique dental adaptations in response to their extreme environment and traditional diet. This study aims to examine in detail the characteristics of their dentition, focusing on the following aspects:

• Dental wear: Severe dental abrasion due to chewing tough foods and using teeth as tools.
• Tooth size and shape: Morphological adaptations related to chewing raw meat and fish, as well as consuming animal fats.
• Dental pathologies: The prevalence of certain dental conditions, such ashypercementosis and attrition, in relation to diet and cultural practices.
• Dental genetics: Genetic variations associated with dental adaptations specific to Arctic populations.

This research will be based on an interdisciplinary approach, combining dental anthropology, paleopathology, genetics, and archaeology. The analysis of data from osteological collections, genetic studies, and clinical observations will provide a better understanding of the mechanisms of dental adaptation in Arctic populations and their evolutionary significance.

Objectives:Describe the characteristics of the dentition of humano-murian populations. • Identify the environmental and cultural factors that influenced the evolution of their dentition. • Explore the evolutionary implications of these dental adaptations.

Methodology: Analysis of osteological collections from humano-murian populations. • Genetic studies of contemporary humano-murian populations. • Review of the scientific literature on dental anthropology and human evolution. • collection of archeological data.
