Scientists extract complete human genome from ‘gum’ more than 5,700 years ago

Scientists have managed to extract a complete human genome from a 5,700-year-old piece of “gum”, which is believed to have been found in southern Denmark,media reported. By analyzing THE DNA, scientists found that the person who had bitten the “gum” was a woman and named her Lola. They even figured out her diet and identified the bacteria in her mouth.

It is understood that the ancient gum discovered by the research team is the — of the birch tree asphalt, by heating the bark of the birch tree produced by the black-brown substance. Asphalt can be used as a base adhesive and is often used in the process of making stone tools.

Many of the prehistoric eucalyptus asphalt materials found and the tooth prints on them indicate that they have been chewed. There are many reasons why the ancients chewed asphalt. For example, making the asphalt hardened during the cooling process soften again by chewing, or using the mild corrosion that it possesses to relieve toothache, and one possibility may be treated as a pastime, like modern chewing gum.

The newly discovered asphalt specimen was discovered by archaeologists who excavated it in a place in southern Denmark called Syltholm.

Theis Jensen, a postdoctoral fellow at the Global Research Institute at the University of Copenhagen, says Syltholm is unique because it is almost sealed with dirt, which means the organic residue there is very well preserved. “This is the largest Stone Age site in Denmark, and archaeological findings suggest that its owners began extensive exploitation of wild resources during the Neolithic period, when farming and domesticated animals were first introduced to southern Scandinavia. “

Incredibly, the team behind the new study was able to extract traces of the entire human genome, as well as the DNA of plants and animals, from eucalyptus asphalt. The genome is basically a complete set of DNA, which includes all of a person’s genes — a comprehensive information catalogue — and if there is the right tool it can even reveal some of the characteristics of a person who has been dead for more than 5,000 years.

The newly discovered biological treasure is the first to extract a complete human genome from human bones. This makes prehistoric birch a valuable source of DNA, and it could reveal a lot about ancient humans.

An analysis of the genome by the team revealed that the former owner of the eucalyptus asphalt was a woman who may have dark skin and hair, right, and blue eyes. These individuals may be closer to hunters living on the Continent than to those who lived in Denmark at the time.

The “gum” also found the duck’s DNA and the hazelnut’s DNA, which the team believes reflects Lola’s eating habits.

In addition, pathogens and bacteria are also found in which EB virus DNA.

Hannes Schroeder of the University of Copenhagen, who led the study, said specimens such as eucalyptus asphalt could help scientists better understand the evolutionary pathways of ancient pathogens and how they have spread over time, and that in the future, it could even help researchers understand how they will spread in the future. This means it will be able to tell modern scientists how to successfully control and eradicate them.
