The 5700-year-old chewing gum contains the complete human genome.

It seems that our ancestors already knew the pleasure and benefits of chewing gum, so that we are able to find out how they looked like.
Scientists successfully extract the complete human genome from a 5700-year-old chewing gum that was discovered some time ago in Denmark. Through DNA analysis, the researchers found that her user was a woman whom they named Lola, and they also learned a lot about her diet and bacteria living in her mouth. The ancient chewing gum is a birch sticky, created by heating the bark of this tree was also used to create tools.
We have also known that they were used for chewing for a long time, because researchers have repeatedly found their pieces with imprinted teeth. And why did the ancients chew gum? There are many possible reasons, and one of them may be the desire to give the substance softness, because the adhesive becomes hard when its temperature drops. Health issues could also have been involved, as birch has bactericidal properties, so it could be used for tooth or throat pain. The pleasure of chewing, which we still value very much today, cannot be excluded.
The rubber was found in a place called Syltholm in the south of Denmark, which according to scientists: - This place is completely unique. Almost everything is covered with mud there, which means that the behavior of organic debris is absolutely phenomenal there.
Archaeological findings suggest that the people who lived there heavily exploited natural resources during the Neolithic, which was the time when agriculture and domestic animals began to reach Scandinavia. What's amazing, now we know more about them, because scientists managed to extract from the rubber found the entire human genome, as well as traces of plants and animal DNA.
The genome is practically a complete DNA set containing the genes of a specific person - an entire catalog of information that, with the help of appropriate tools, can show a very detailed description of a person who has been dead for over 5,000 years. This is the first time that researchers have managed to extract genes from something other than human bones, which gives the find even more significance - now, for example, you can once again miss chewing gums found before. Genome analysis revealed chewing gum was a woman with dark skin and hair and blue eyes, which was more like hunter gatherers living in continental Europe at that time than the typical Danish people of that period. In the birch mud, traces of duck and nut DNA were also found, which gives a nice picture of the diet of our ancestors at that time.
