The University of Turku in Finland and a number of scientific research institutions recently jointly published a multidisciplinary study, which reanalyzed an ancient tomb about 400 years ago near Lake Kitka in Kusamo in northern Finland. It was found that the male individual in the tomb was genetically very close to the contemporary Sami people, and his lifetime footprints were likely to span the North Atlantic and even as far away as Iceland.
This tomb was first discovered on the shores of Lake Kitka in the 1970s. The latest research extracted ancient DNA from the teeth of the tomb owner and compared it with published genome data of ancient and modern populations. The results showed that the man who died at about 40 years old was the closest in genetic makeup to the historical and contemporary Sami people. Research also shows that he also shares a certain degree of short-segment DNA with present-day Finns, especially the genetic relationship with people living in northern and northeastern Lapland, while the genetic connection with the local residents of Kuusamo and southern Finland is relatively weak.
The researchers pointed out that when a similar analysis was conducted against the contemporary Sami people, similar genetic patterns to those of the "Kitka individuals" emerged, indicating that the results reflected not individual cases, but broader and ongoing historical interactions and genetic exchanges between the Sami and Finns. However, the research team also emphasized that although ancient DNA can help reconstruct population migration and relationship genealogies, it cannot be used to define a specific individual's ethnic identity or cultural affiliation. Sami identity is viewed as a historical, cultural and social phenomenon rather than a single biological marker.
Due to the age of the tomb, the "Kitka individual" has also attracted the attention of genetic genealogy enthusiasts, but the research team made it clear that the existing DNA evidence is not enough to reliably trace this individual from the turn of the 16th to 17th centuries to any specific contemporary family or individual. Within the broader framework of population history research, this burial individual is more representative of its overall connection with the Sami population rather than its precise correspondence with a single lineage.
Isotope analysis, carried out in conjunction with genetic analysis, provided key clues to the trajectory of the man's life. By analyzing isotope signals in his teeth that reflect his diet and drinking water sources during childhood and adolescence, the study found that his food structure during his growth period included terrestrial animals, freshwater fish, and marine resources. However, in later life, marine foods increased significantly in his diet, and freshwater fish—a traditional important food source in the Kuusamo region—basically disappeared. At the same time, the isotope signature of the drinking water recorded in the teeth showed that the geological background of the area where he lived as a boy was significantly different from that of mainland Finland.
Based on geochemical characteristics and historical documentary evidence, the research team believes that the man most likely lived in a volcanic bedrock area in the North Atlantic during his teenage years, with Iceland being the most suitable candidate area. This inference is mutually corroborated with historical records of extensive connections between Northern Fennos, Scandinavia and the North Atlantic region in the 16th century, suggesting that the range of activities of high-latitude people in Northern Europe at that time was far beyond previous imagination.
Earlier studies speculated based on the shape of the tomb and the burial conditions that the "Kitka individual" may be a Sami wizard (noaidi) or a ritual expert with special religious functions. This latest comprehensive bioarchaeological analysis does not completely deny this possibility, but the results show that his life experience and social role are likely to be more complex than the existing narratives, and the stereotypes of historical Sami society in old studies cannot be simply applied. The research team pointed out that this study shows the social structure and mobility of the Sami people in the 16th century from an individual level, which is significantly different from the description of Sami social roles in traditional literature.
This study uses the "Kitka individual" as a clue, and through cross-analysis of ancient DNA and isotopes, re-places a Nordic man who lived four hundred years ago into a broader historical and geographical context. The research not only provides new evidence for understanding the historical evolution of the Sami people and their long-term interaction with the Finnish population, but also supplements the archaeological and biological evidence of the cross-regional exchange network in the North Atlantic region in the 16th century. Relevant results have been published in the journal BMC Genomics. The paper is titled "Bioarchaeological analysis reveals the life history of 16th-century Sami individuals in the Kusamokitka region of northern Finland."
