Pioneering Research Directly Dates The Earliest Milk Use In Prehistoric Europe

The international research, led by the University of Bristol and published today in Proceedings of the National Academy of Sciences (PNAS), deployed a pioneering technique to date dairy fat traces preserved in the walls of pottery vessels from the 54th century BC. This method targets fatty acids from animal fat residues, making it uniquely suited to pinpointing the introduction of new foodstuffs in prehistoric times.

Lead author Dr. Emmanuelle Casanova, who conducted the research while completing her Ph.D. in archaeological chemistry at the University of Bristol, said, "It is amazing to be able to accurately date the very beginning of milk exploitation by humans in prehistoric times. The development of agropastoralism transformed prehistoric human diet by introducing new food commodities, such as milk and milk products, which continues to the present day."

These settlers of South East, East, and West of Europe were the earliest Neolithic farming groups in Central Europe, known as the Linearbandkeramik (LBK) culture. The findings of this research showed some of the very first settlers in the region were using milk at scale.

This work was part of the European Research Council (ERC) NeoMilk project led by Professor Richard Evershed FRS of the School of Chemistry at the University of Bristol. His team analyzed more than 4,300 pottery vessels from 70 LBK settlements for their food residues. The results revealed considerable variation in milk use across the region, with only 65% of sites presenting evidence of dairy fats in ceramics vessels, suggesting milk use, while common, was not universally adopted by these early farmers.

Focusing on the sites and ceramics with dairy residues, the researchers produced about 30 new radiocarbon dates to chart the advent of dairy exploitation by LBK farmers. These new dates correspond to the earliest LBK settlements during the middle of the 6th millennium BC.
