Human DNA Found In 5700 Year Old ‘Chewing Gum’

Human DNA Found In 5700 Year Old ‘Chewing Gum’ December 19, 2019Leave a comment

Danish scientists have succeeded in preparing the complete DNA of a human from a resin sample of a birch tree more than 5700 years old. With its help, scientists have been able to extract much important information.


The sticky resin of the Himalayan Birch tree was probably used for something like chewing gum at that time. With the help of this Stone Age sample, scientists have found out what was the gender of that human and what was the last time he ate. With this, it has also been ascertained what kind of germs were present in the mouth of that person. Scientists say that she was a woman with black hair, skin black, and eyes blue. Genetically, the woman was very close to the hunter nomads of Europe, who then lived in central Scandinavia.


“For the first time, the entire genome of an ancient human has been successful in extracting it without human bones,” said researcher Hannes Schroeder of Copenhagen University. A report has been published in the journal Nature Communications about this. Schroeder is the coauthor of this research report.
Scientists found this specimen during an archaeological dig at Saltholm in southern Denmark. Tehis Jensen, one of the authors of the report, said, “Saltholm is absolutely unique. Everything is wrapped in the mud. This means that the preservation of organic residue is very good.”


Researchers have also discovered fragments of DNA of some organisms and plants. They also include hazelnuts (a kind of nuts) and ducks. Scientists have already talked about humans living here, these discoveries have confirmed this. Although scientists have not yet known why people chewed the resin of Himalayan Birch at that time.


Was it done to make gum or was it to clean the teeth or was it just a kind of chewing gum.
