Linking isotope analysis and paleopathology: An andean perspective

Area of Science:

• Paleoanthropology
• Bioarchaeology
• Isotope Geochemistry

Background:

• The Central Andes offer exceptional preservation of human remains, ideal for biogeochemical and isotopic studies.
• Isotopic investigations have primarily focused on diet and mobility in the region since the 1980s.

Observation:

• A meta-analysis of 96 publications (1980-2017) reveals a surge in Andean isotopic research, with a notable increase in the last decade.
• Studies combining isotope analysis with paleopathology remain sparse despite the potential benefits.

Findings:

• Isotope analysis provides crucial data on diet, mobility, and local ecology, enhancing the study of pathological conditions.
• Despite challenges like tissue destruction and data complexity, isotope analysis offers unique insights into disease pathogenesis and differential diagnosis.

Implications:

• Future research should integrate stable isotope analysis more explicitly into Andean paleopathology studies.
• Developing research designs pairing isotopic and paleopathological variables can illuminate disease ecologies across diverse Andean contexts.
