Jessica Metcalf is an evolutionary biologist who is fascinated by old things. At the core of her research is the use of ancient DNA methods to directly sample genes from the past to answer questions in ecology, evolution, conservation, forensics and history. Whether only weeks old, from historic times or the late Pleistocene, DNA preserved in bone, teeth, hair, tissue, coprolites, plant material and soil can solve mysteries about the past.
