5,700 years old chewing gum

Researchers from the University of Copenhagen have succeeded in extracting a complete human genome from a thousands-of-years old “chewing gum”. 17th Annual Photo Contest Finalists Announced. DNA is one of scientists’ best sources of information about people, but the more ancient the person, the harder it can be to find viable DNA to examine. The ancient DNA, described in a paper published Tuesday in Nature Communications, is especially valuable because few human bones from the Mesolithic and Neolithic Stone Ages have been found in Scandinavia. When hunter-gatherers living in what is now southern Denmark broke down pieces of birch bark into sticky, black tar about 5,700 years ago, they almost certainly didn’t realize that they were leaving future scientists their entire DNA. From the DNA, researchers can start to piece together some of the ancient woman’s physical traits and make some inferences about the world she lived in. In a landmark study, scientists have reconstructed the genome of an ancient human who lived some 5,700 years ago in what we now know as southern Denmark. London: For the first time, researchers have extracted an entire ancient human genome from a sample other than bones, in a gum chewed by a 5,700-year-old female, unearthing details about the diet and oral microbes of stone age people. Researchers from the University of Copenhagen have succeeded in extracting a complete human genome from a thousands-of-years old “chewing gum”. 5,700-year-old 'chewing gum' offers snapshot of ancient people By Melissa Busch, DrBicuspid.com assistant editor. Gum is generally a one and done piece of entertainment. They have been noted in reconstructions of a 10,000-year-old British skeleton called the Cheddar Man, as well as other European hunter-gatherers. “This sample had lots of microbial DNA preserved as well.”. Scientists have extracted and fully sequenced the genome of a human girl from a piece of chewing gum that’s 5,700 years old. The birch pitch sample also had traces of Streptococcus pneumoniae bacteria and Epstein-Barr virus, which provide clues to Lola’s health. Planned construction of the underwater tunnel, which will connect the Danish island of Lolland with the German island of Fehrman, has forced archaeologists to rush to collect artifacts and fossil evidence before they are lost forever. The team nicknamed the young Neolithic woman "Lola" after Lolland, the island in Denmark on which the 5,700-year-old chewing gum was discovered. 5,700 Year Old Chewing Gum Reveals Insights On Prehistoric Hunter-Gatherer Life in Denmark Theis Jensen, a bioarchaeologist at the University of Copenhagen, and colleagues, published a report in Nature Communications about a the finding of a South Danish Neolithic woman’s complete genome and oral microbiome from a piece of birch tar she chewed. Give a Gift. “It’s really interesting that we can start working on this material, because there’s a lot of it scattered around Scandinavia from the Stone Age to the Iron Age,” she says, adding that gums may survive wherever birches were prevalent—including eastward toward Russia, where one wave of Scandinavian migration is thought to have originated. “The dietary evidence, the duck and the hazel nuts, would also support this idea that she was a hunter-gatherer and subsisted on wild resources,” Schroeder says, noting that the site is littered with physical remains which show reliance on wild resources like fish, rather than domesticated plants or animals. Researchers Extract and Sequence Human DNA from 5,700-Year-Old ‘Chewing Gum’ ... A 5700 year-old human genome and oral microbiome from chewed birch pitch. Flaked stone tools and T-shaped antler axes gave way to polished flint artifacts, pottery and domesticated plants and animals. During excavations on Lolland, archaeologists have found a 5,700-year-old type of “chewing gum” made from birch pitch. Scientists are unable to glean an individual’s age from the DNA stored in the sample. “This is supposed to be a time when farming has already arrived, with changing lifestyles, but we find no trace of farmer ancestry in her genome, which is fairly easy to establish because it originated in the Near East. The entire genome of a female who lived in Denmark 5,700 years ago has been sequenced, from a piece of prehistoric “chewing gum.” It’s impossible to know whether she was a girl or full-grown woman, but like other early Europeans, as we know now, she likely had dark skin, dark hair and blue eyes, Theis Jensen of the University of Copenhagen and a host of co-authors reported Tuesday in … When they spat the gum out, the same antiseptic properties helped preserve the DNA in their saliva. Usually benign, the virus can be associated with serious diseases like infectious mononucleosis, Hodgkin’s lymphoma and multiple sclerosis. Whether the region’s turn to farming was a lifestyle change among local hunter-gatherers, or spurred by the arrival of farming migrants, remains a matter of debate. Modern chewing gums, which often contain polyethylene plastic, could stick around for tens or even hundreds of years, and perhaps much longer in the right conditions. (Experts believe Northern Europeans evolved lighter skin and hair to adapt to the lower light conditions in regions where they lived much later on, and the genetic mutation for digesting milk came around once they became more dependent on livestock for food.). “It’s interesting because it’s the same combination of physical traits that apparently was very common in Mesolithic Europe. A 5,700-yr-old piece of “chewing gum” has been used to recreate the entire genome of an ancient Scandinavian girl.

Scientists suspect several reasons why people would have chewed it: to make it malleable once again after it cooled, to ease toothaches because it’s mildly antiseptic, to clean teeth, to ease hunger pains, or simply because they enjoyed it. The Danish team identified several species of bacteria that were similar to those hiding in people’s plaque and on the tips of their tongues today. By IANS 19 December 2019 TWC India This image is an artistic reconstruction of the woman who chewed the birch pitch. “It’s as well-preserved as some of the best petrous [skull] bones that we’ve analyzed, and they are kind of the holy grail when it comes to ancient DNA preservation.”. “We may expect this process, especially at this late stage of the Mesolithic, to have been complex with different groups, from south, west or even east, moving at different times and sometimes intermingling while perhaps other times staying isolated,” Jan Storå, an osteoarchaeologist at Stockholm University, says via email. Archaeologists found a 5,700-year-old wad of "chewing gum" — a piece of birch-tree pitch — in Lolland, Denmark. She was a female, and while her age is unknown, she may have been a child considering similar birch pitch gums of the era often feature the imprints of children’s teeth. For archaeologists, the sticky stuff’s longevity can help piece together the lives of ancient peoples who masticated on the chewy tar. “These birch pitch chewing gums are kind of special in terms of how well the DNA is preserved. So all these other ancient [European] genomes that we know about, like La Braña in Spain, they all have this combination of physical traits that of course today in Europe is not so common. December 20, 2019-- A complete human genome, oral microbes, and human pathogens were retrieved from a 5,700-year-old type of "chewing gum," untapping a new source of ancient DNA and shedding light on the person who chewed it, according to research published on … “DNA from ancient pathogens holds great promise, and this type of mastics may be a much better source for such data than ancient bones or teeth.”.
