In an intriguing archaeological discovery, researchers have analyzed DNA extracted from 9,700-year-old chewed resin to gain insights into the diet and health of Mesolithic hunter-gatherers in Scandinavia. This study provides a unique glimpse into the lives of these ancient people, offering valuable information about their food sources, oral health, and potential diseases.

DNA Diet, Disease Insights from Ancient Chewed Resin

The study focused on resin pieces found at the Huseby Klev site in Sweden, which date back to approximately 10,200 to 9,400 years ago. These resin pieces, made from birch bark pitch, were chewed by teenagers, both boys and girls, likely for adhesive purposes in toolmaking. Remarkably, DNA analysis revealed that half of the DNA extracted from the resin was of human origin, providing valuable genetic information about these ancient individuals.

Revealing the Mesolithic Diet, Disease Insights

The DNA analysis provided insights into the diet of these hunter-gatherers. Traces of red deer, brown trout, and hazelnuts were identified, indicating that these foods were part of their diet. However, it is important to note that the accuracy of these findings depends on the availability of comparative data for eukaryotic organisms, which includes plants and animals.

Oral Health and Potential Diseases Insights from Ancient DNA

The study also shed light on the oral health and potential diseases of these ancient individuals. Bacteria associated with tooth decay (Streptococcus mutans) and gum disease (periodontitis) were detected, suggesting that these conditions were prevalent among the Mesolithic population. However, it is crucial to interpret these findings cautiously, as the presence of these bacteria does not necessarily indicate the presence of active disease.

A Glimpse into the Past: Diet, Disease Insights

This study offers a fascinating glimpse into the lives of Mesolithic hunter-gatherers in Scandinavia. By analyzing DNA from ancient chewed resin, researchers have gained insights into their diet, oral health, and potential diseases. This research contributes to our understanding of the lives and health of our ancestors, providing valuable information about their daily lives and the challenges they faced.

Wrapping Up: Ancient DNA Diet, Disease Insights

The analysis of DNA from ancient chewed resin has provided valuable insights into the diet and health of Mesolithic hunter-gatherers in Scandinavia. This research highlights the potential of ancient DNA studies to shed light on the lives of our ancestors and deepen our understanding of human history. As more ancient DNA is analyzed, we can expect to uncover even more fascinating details about the lives of our prehistoric predecessors.. The keywords are: Ancient DNA diet disease.

Ancient DNA
Ancient DNA (aDNA) is DNA isolated from ancient specimens. Due to degradation processes (including cross-linking, deamination and fragmentation) ancient DNA is more degraded in comparison with contemporary genetic material. Even under the best preservation conditions, there is an upper boundary of 0.4–1.5 million years for a sample to contain sufficient...

Eastern Hunter-Gatherer
In archaeogenetics, the term Eastern Hunter-Gatherer (EHG), sometimes East European Hunter-Gatherer, or Eastern European Hunter-Gatherer is the name given to a distinct ancestral component that represents Mesolithic hunter-gatherers of Eastern Europe. The Eastern Hunter Gatherer genetic profile is mainly derived from Ancient North Eurasian (ANE) ancestry, which was introduced from...

DNA profiling
DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid (DNA) characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA...
