"Stone Age Chewing Gum Unveils Scandinavia's Ancient Diet and Health"
DNA analysis of chewed resin from Stone Age hunter-gatherers in Scandinavia reveals their diet, health, and culture. The resin, dated to 9,700 years ago, contained human DNA, indicating the presence of teenagers, both boys and girls, who were likely preparing glue for tool making. The DNA also revealed traces of bacteria associated with periodontitis, suggesting that one of the teenagers suffered from severe gum disease. Additionally, DNA from red deer, brown trout, and hazelnuts was found, shedding light on the group's diet and lifestyle during the Mesolithic period.
