In a breakthrough study, researchers have solved a 5,000-year-old cold case, shedding light on the life and death of a Neolithic man whose bones were discovered in a Danish peat bog over a century ago. The findings, published in the journal PLOS One, reveal that this ancient individual, dubbed "Vittrup Man," was an immigrant flint trader who met a violent end at the hands of hostile locals.

The investigation into Vittrup Man's story began in 1915 when human and bovine bones, a ceramic pot, and a wooden club were unearthed by peat diggers near the village of Vittrup in northern Denmark. While the pottery and club were swiftly taken to the National Museum of Denmark, the bones remained unstudied for a century.

Recent genomic analysis of ancient European populations provided crucial insights into Vittrup Man's origins and life. The study revealed that he lived between 3300 and 3100 B.C., and his genetic profile differed from that of his local contemporaries. These findings strongly suggested that Vittrup Man was an itinerant flint trader, who hailed from a fisher-hunter group from the northern Scandinavian coast.

The researchers utilized various methods to piece together Vittrup Man's life history. The examination of his dental plaque, rich in DNA and proteins, unveiled a diverse diet that included fish such as cod and sea bream, as well as whale meat, dolphin meat, and mutton. Analysis of carbon isotopes in his teeth indicated a shift towards terrestrial and freshwater food sources during his teenage years, coinciding with a geographical relocation to a farming community.

While the reason behind Vittrup Man's move remains unclear, one theory suggests that he ventured out in search of flint axes and agricultural goods to trade from his native land. However, an alternative hypothesis proposes that he may have been captured and enslaved by a hostile group.

Tragically, Vittrup Man's life came to a brutal end. The researchers discovered that his skull and jaw exhibited multiple fractures from at least eight blows, which proved fatal. Oval-shaped fractures suggested blunt force trauma inflicted by a rounded object, potentially similar to the wooden club unearthed from the peat bog. The researchers speculate that Vittrup Man may have been a victim of feuding or possibly sacrificed during a ritualistic activity.

Anders Fischer, the lead archaeologist in the study, highlighted that the site where Vittrup Man was found was associated with sacrificial activities during the Neolithic period. However, the specific deity or purpose for the sacrifices remains unknown. It is believed that individuals sought favor from an unknown spirit or deity through the offering of valuables, including humans and cattle.

Commenting on the research, bioarchaeologist Alexis Boutin, who was not involved in the study, commended the wide-ranging evidence brought together by the researchers. Boutin emphasized how Vittrup Man's story provided invaluable insights into the transition from foraging to farming, hunting practices, regional migration, exchange, and ritualized sacrifice.

The diligent analysis of Vittrup Man's bones and genetic markers has not only unraveled a 5,000-year-old cold case but has also offered a fascinating snapshot of the lives and customs of ancient European communities during a pivotal period in history.
