DNA of Long-Dead Cows Read from Pages of Medieval Books| New Scientist
Seven years ago, Matthew Collins at the University of Copenhagen in Denmark and his colleagues had the idea of applying state-of-the-art genetic analysis techniques to the animal skin pages of medieval documents.
“We realised all these dead cows have a date written on them,” he says. “We thought, ‘This is crazy, why aren’t we exploiting this’.”
Wow.
