A woman buried in Croatia in the Mesolithic era

The Mesolithic era, often referred to as the Middle Stone Age, is a period that bridges the gap between the Paleolithic (Old Stone Age) and the Neolithic (New Stone Age). It is characterized by the adaptation of human populations to post-glacial environments and significant developments in tool technology and subsistence strategies. The Mesolithic Hunter-Gatherers of Croatia, like their counterparts across Europe, were a resilient and adaptive group of people who managed to thrive during a time of significant climatic and environmental shifts.

Geographic Context

The region that is modern-day Croatia presents a diverse geography, ranging from the Pannonian Plain in the east to the mountainous Dinarides in the central area, extending to the Adriatic Sea coastline in the west. This diverse landscape provided a variety of ecological niches and resources which Mesolithic hunter-gatherers exploited.

Environmental and Climatic Background

The Mesolithic period followed the Last Glacial Maximum, a time marked by significant climatic amelioration. As the ice sheets retreated, the climate became warmer and more stable, leading to the establishment of rich deciduous forests, open woodlands, and expansive wetlands in what is now Croatia. These environments supported a variety of faunal species and produced a shift in the subsistence strategies of human groups as they adapted to the changing conditions.

Subsistence Strategies

Mesolithic economies across Europe, including those in Croatia, were predominantly based on hunting, gathering, and fishing. The diversity in Croatia’s landscapes provided various opportunities for exploitation:

• Hunting: The presence of large and small game such as red deer, wild boar, aurochs, and a variety of bird species was integral to the diet. Hunter-gatherers utilized tools made from flint and other stones, crafting microliths that could be hafted onto wooden shafts to create effective hunting weapons.

• Gathering: The forested areas offered a wealth of resources in the form of nuts, berries, fruits, and tubers. Seasonal mobility would allow groups to exploit these resources when they were most abundant.

• Fishing and Aquatic Resources: The proximity to rivers, lakes, and the Adriatic Sea meant that fishing was a crucial component of Mesolithic subsistence. Evidence suggests the use of fishing hooks, nets, and possibly boats to exploit marine and freshwater resources.

Tool Technology and Material Culture

The technology of the Mesolithic period saw a continued refinement and diversification from the preceding Paleolithic:

• Microliths: These small, geometric flakes of stone were used as components of complex composite tools. They were often mounted onto wooden or bone handles to create arrows and spears, showcasing an innovative use of resources.

• Bone and Antler Tools: Beyond stone, Mesolithic peoples made extensive use of organic materials. Harpoons, awls, and other tools carved from bone and antler reflected the ingenuity and adaptability of these communities.

• Wooden and Plant Materials: Although wood and plant materials rarely survive in the archaeological record, indirect evidence suggests the use of woven baskets, wooden containers, and other plant-based tools.

Social Organization and Settlements

While the Mesolithic is traditionally seen as a period of small, semi-nomadic bands, it's important to recognize the diversity and complexity within these societies:

• Mobility: Seasonal mobility was a hallmark of Mesolithic life, with groups moving between resource zones. However, there is evidence of semi-permanent base camps, particularly in resource-rich areas.

• Social Structure: Although much about Mesolithic social organization remains speculative, the organization of space within sites suggests structured group activities and potentially complex social relationships.

• Art and Symbolism: While less prevalent than in the Paleolithic, there is evidence of artistic expression in the form of personal ornaments and possibly engraved objects, indicating a role for symbolic and ritualistic practices.

Archaeological Sites and Discoveries

The Mesolithic period in Croatia is evidenced by various archaeological sites, particularly in coastal and riverine contexts. These sites provide crucial insights into the lifeways of Mesolithic peoples. They include:

• Open-Air Sites: Often found near water sources, these sites reveal information about daily activities, tool production, and subsistence practices.

• Cave and Rock Shelter Sites: Such locations provided natural protection and have preserved organic materials that offer valuable insights into the food and technologies used by these communities.

Conclusion

The Mesolithic hunter-gatherers of Croatia were an adaptive and resilient people who responded to changing environmental conditions with increasingly sophisticated technologies and diverse subsistence strategies. Through the lens of archaeology, their legacy provides insights into human creativity, adaptability, and the transition towards more settled and complex societies that would define the Neolithic revolution. As ongoing research and excavation continue, our understanding of these enigmatic communities continues to grow, painting a more detailed picture of life in prehistoric Europe.

Ancient genetic admixture analysis compares the DNA profile of this individual (I1875) with present-day reference populations. These results show what percentage of the individual's genetic makeup resembles ancient populations from different geographic regions.

Modern genetic admixture analysis compares the DNA profile of this individual (I1875) with present-day reference populations. These results show what percentage of the individual's genetic makeup resembles modern populations from different geographic regions.

These results complement the ancient ancestry components shown in the previous section, offering a different perspective on the individual's genetic profile by comparing it with modern reference populations rather than prehistoric ancestral groups.
