Can ancient chewing gum be used to study early human DNA?

Last post, recent discoveries were mentioned which depicted uncovering bones that contributed to the discovery of Homo Luzonenis in the Philippines.  Another example of an excavation that unearthed early humans occurred in present-day Bulgaria and Greece.  The remains suggest

that humanity began in Southern Europe, and also reached its conclusions through the analysis of a tooth and a jaw- similar to the recent Filipino discovery.  Fossil analysis is a common method used to unlock history. However, there are other means of harvesting ancient DNA.

Interestingly, there is a recent study which examined ancient Scandinavian DNA by inspecting ancient chewing gum.  Research  from all over the internet including articles from Stockholm University state that through analysis—chewing gum from thousands of years ago has been able to tell us a story about ancient humans living in Scandinavia. Sources tell us that these ancient humans likely migrated to present day Northern Europe (Scandinavia) over 10,000 years ago.  It is stated by the University’s website that when the pieces of gum were analyzed, it was discovered that they contained the oldest remnants of Homo Sapiens DNA ever discovered in Scandinavia.  While the article delves into a great deal of detail which can be accessed using the link below, the conclusion reached is essentially that accessing DNA from multiple sources (including chewing gum) equips researchers with increased possibilities of unlocking the door to history which would have been inaccessible in the recent past.  It also asks the question: what information will we as humans be capable of attaining in the future?  On the other hand, is it possible that this will also be followed by potentially “negative” consequences?
