Reconstructing prehistoric plant use from sedimentary ancient DNA

Plants have always played an integral part in human life, as fuel, medicine, food and other uses. But prehistoric plant use is difficult to study, because plant remains such as seeds, leaves, fruits and roots rarely survive in the archaeological record. Remarkably, plant DNA can survive in sediments for tens of thousands of years, even without the preservation of visible remains. Analysing such sedimentary ancient DNA from archaeological sites allows us to study human behaviour and at the same time reconstruct local environmental conditions during the past.

We have sediment samples from several caves in Norway spanning the past 10 000 years. Some of these sites were used intensively by people in the past, as shelter or as places for ritual purposes, other caves were visited more infrequently. We also continue to excavate new sites and collect new samples. Combining sedimentary ancient DNA with pollen analyses we are interested in studying the diversity of plants preserved at these sites. Using radiocarbond dating and by comparing this data to the faunal diversity and archaeology we aim to increase our understanding of human plant use during the Holocene and the role plants may have played in early societies and livelihoods in Norway.
