This project investigates the peopling of South America, the last continental terra incognita (other than Antarctica) to be colonised by humans.
Reconstructing past environments using ancient environmental DNA (eDNA) in the Paleo Environmental Genomics Group
The Paleo Environmental Genomics Group (PEGG) focus is to use shotgun sequenced ancient DNA and DNA metabarcoding to reconstruct past environments in order to address scientific questions concerning the interaction between past humans – environments – climatic changes and their effect on species distribution, speciation, evolution, population structure and community compositions.
We operate across a range of research fields including geology, archaeology, biology and geography where we extract and analyse ancient DNA data to answer questions about the past. The different projects currently cover 5 different continents, Africa, North America, South America, Europe and Asia, and includes reconstruction of past environments, speciation, and human activities.
“Being part of developing this new methodology – it is important to constantly explore and evolve the boundaries of the method – while still addressing important scientific question. We are therefore constantly working on improving and expanding its possibilities in both the laboratory and computational”, says Mikkel W. Pedersen, group leader.
