Christina Warinner is a researcher at the University of Zurich, where she studies how humans have co-evolved with environments, diets and disease.
Tna analyzes DNA from the bones and teeth of ancient people to study human evolution in response to changes in infectious disease, diet and the environment over the last 10,000 years. Using samples from ancient skeletons and mummies, she investigates how and why lactase persistence, alcohol intolerance and HIv-resistance have evolved in different populations around the world. As an archaeogeneticist, she’s particularly interested in bridging the gap between archaeology, anthropology and the biomedical sciences.
“We can generate immense quantities of data [from dental calculus] that then we can use to begin to reconstruct a detailed picture of the dynamic interplay between diet, infection and immunity, thousands of years ago.”
“On behalf of future archeologists, I would like to ask you to please think twice before you go home and brush your teeth.”
