Do "Chewing Gum" Exist In The Ancient Time
Thousands of years ago, a young Neolithic woman in what is now Denmark chewed a piece of birch bark pitch, which was later found on the ground in modern times.
DNA
analysis of this prehistoric "chewing gum" has revealed remarkable details about her appearance.
The woman has been nicknamed "Lola" after Lolland, the Danish island where the artifact dating back 5700 years was found.
The Syltholm archaeological site preserved the chewing gum in mud for thousands of years, and it was possible to extract a complete ancient human genome from it, including DNA from ancient pathogens and oral microbes that the girl had in her mouth.
DNA analysis by the University of Copenhagen revealed that the woman had dark skin, dark brown hair, and blue eyes, allowing for a reconstruction of her appearance.
