How can technology help push the boundaries of archaeology study

Biomolecular methods use molecular biology and chemistry—DNA, proteins, lipids, isotopes—to extract biological and chemical signatures from archaeological materials (bones, teeth, residues, sediments, textiles). They push archaeology’s boundaries by providing direct evidence about past people, animals, plants, diets, diseases, mobility, and environments rather than relying only on tools or context. Key contributions include ancient DNA (aDNA) for population history and kinship; proteomics to identify species from degraded remains and artifacts; stable isotope analysis to reconstruct diets and migration; and residue analysis to detect foodstuffs, medicines, or pigments. Together these techniques allow finer-grained, testable reconstructions of lifeways, population contact, and environmental change, often resolving questions that material culture alone cannot answer.

These techniques reveal diet, migration, relatedness, disease, domestication, and environmental interactions at levels not visible from artifacts or stratigraphy alone. For example, aDNA can reconstruct population movements and kinship (Haak et al., 2015), proteomics can identify species from fragmentary bone or residues (Bishop et al., 2018), and isotopes track individual diets and mobility (Knudson & Stojanowski, 2009). Together, biomolecular methods transform fragmentary remains into direct evidence about past peoples, animals, plants, and their relationships with environments. References: - Haak, W. et al., 2015.
