    It was in the archives (档案室) of the Archbishop of York that Matthew Collins had a sudden insight: He was surrounded by millions of animal skins.

Another person might say they were surrounded by books and manuscripts written on parchment, which is made from skins, usually of cows and sheep. Collins, however, had been trying to make sense of animal-bone fragments from archaeological digs, and he began to think about the advantages of studying animal skins, already cut into rectangles and arranged neatly on a shelf. Archaeologists consider themselves lucky to get a few dozen samples, and here were millions of skins just sitting there.

In recent years, archaeologists and historians have awakened to the potential of ancient DNA extracted from human bones and teeth. DNA evidence has enriched — and complicated — stories of prehistoric human migrations. It has provided tantalizing clues to epidemics such as the black death. It has identified the remains of King Richard III, found under a parking lot. But Collins isn’t just interested in human remains. He’s interested in the things these humans made; the animals they bred, slaughtered, and ate; and the economies they created.

That’s why he was studying DNA from the bones of livestock — and why his lab is now at the forefront of studying DNA from objects such as parchment and beeswax. These objects can fill in gaps in the written record, revealing new aspects of historical production and trade. How much beeswax came from North Africa, for example?

Collins splits his time between Cambridge and the University of Copenhagen, and it’s hard to nail down exactly what kind of — ologist he is. He has a knack for gathering experts as diverse as parchment specialists, veterinarians, geneticists, archivists, economic historians, and protein scientists (his own background). “All I do is connect people together,” he said. “I’m just the ignorant one in the middle.”

However, it didn’t take long for his group to hit their first culture conflict. In science and archaeology, destructive sampling is at least tolerated, if not encouraged. But book conservators were not going to let people in white coats come in and cut up their books. Instead of giving up or fighting through it, Sarah Fiddyment, a postdoctoral research fellow working with Collins, shadowed conservationists for several weeks. She saw that they used white Staedtler erasers to clean the manuscripts, and wondered whether that rubbed off enough DNA to do the trick. It did; the team found a way to extract DNA and proteins from eraser pieces, a compromise that satisfied the team found a way to extract DNA and proteins from eraser pieces, a compromise that satisfied everyone. The team has since sampled 5,000 animals from parchment this way.

Collins is not the first person to think of getting DNA from parchment, but he’s been the first to do it at scale. Studying the DNA in artifacts is still a relatively new field, with many prospects that remain unexplored. But in our own modern world, we’ve already started to change the biological record, and future archaeologists will not find the same treasure of hidden information in our petroleum-laden material culture. Collins pointed out that we no longer rely as much on natural materials to create the objects we need. What might have once been leather or wood or wool is now all plastic.
