Modern chewing gums, which often contain polyethylene plastic, could stick around for tens or even hundreds of years, and perhaps much longer in the right conditions. Some of the first chewing gums, made of birch tar and other natural substances, have been preserved for thousands of years, including a 5,700-year-old piece of Stone Age gum unearthed in Denmark.
For archaeologists, the sticky stuff’s longevity can help piece together the lives of ancient peoples who masticated on the chewy tar. The ancient birch gum in Scandinavia preserved enough DNA to reconstruct the full human genome of its ancient chewer, identify the microbes that lived in her mouth, and even reveal the menu of a prehistoric meal.
