Origins of Dairying in Ancient Central Asia Project
The consumption of dairy in prehistoric Central Asian societies profoundly affected steppe populations. In addition to nutritional benefits, milk may have also provided an essential uncontaminated water source for pastoralists in marginal environments. Recent research has demonstrated the interconnectedness of Asia, Africa, the Near East, and Europe through the transmission of ideas and technology across Eurasia, across what would become the Silk Road, including the spread of genes and methods for milk production.
South Asian and European populations share the same genetic adaptation for lactose digestion, but whether this diffused through Eurasia remains unclear. Using proteomic, isotopic, and genomic analyses, this project will assess the direct consumption of milk through time in prehistoric Central Asian populations, such as groups inhabiting Mongolia and Turkmenistan, to determine what types of species-specific diary were produced, and the frequency and forms of lactase persistent genotypes and phenotypes.
