Around 6500 years ago, people in the South-Eastern Baltic started making pottery, but their tools remained similar to those from earlier times. The Zedmar culture was a key group in this region, influenced by both Western and Eastern cultures. By studying artifacts from Zedmar sites, researchers found that the economy of this culture was shaped by natural factors and limited agriculture and animal husbandry. This led to a unique mix of Mesolithic traits in their economy, suggesting a specific type of gathering in the South-Eastern Baltic.
