It has been more than 10.000 years since ancient humans have settled in now-called Sweden. They have chewed piles of sticky ground, something like a tar material which was extracted from birch bark. It was supposed to be like a “chewing gum,” and it was recently recovered from a Mesolithic settlement. It still has traces of ancient human DNA. That DNA is the oldest one from Scandinavia, and all of these are actually very valuable, because some of the Mesolithic bones of human have been found in Scandinavia, and some of them still have viable DNA.
Researchers have found eight chewed wads of this kind of ground at a place called Huseby Klev, which is on Sweden’s western coast. People from Scandinavia, in Stone Age, used this kind of gum in order to glue tools.
Ancient Human DNA in Scandinavia Was Found in 10,000-Year-Old “Chewing Gum”
However, in the 1990s, Huseby Klev was excavated, and in that time, it was not possible to see if it was some ancient human DNA. Years later, scientists were able to get DNA from three pieces of this kind of ground. They got the ancient human DNA of 3 individuals, namely, one male and two females. When researchers found out that they can classify DNA from the chewed bumps from 10.000 years ago, the results were amazing. Scientists performed many experiments at the Museum of Cultural History (MCH) in Oslo, Norway.
These samples come with imprints of the teeth from there. These specific three pieces didn’t come with tooth marks, but The black wads showed the consistency of “chewed bubble gum.” However, in comparison with modern kinds of gums, these wads did not contain any artificial sugar. They tested like resin, which is a flavor that is said to be pleasing.
