Fire was crucial for human survival during the most recent Ice Age, but surprisingly little evidence of hearths exists from Europe’s coldest years. Researchers have uncovered new insights into how fire was used during this period by studying three prehistoric hearths in Ukraine.
The team of researchers analyzed three ancient hearths at the Korman’ 9 archaeological site, which date back to between 23,000 and 21,000 years ago. The fires reached temperatures of over 1,112 degrees Fahrenheit, indicating a deep knowledge of fire building among European hunter-gatherers.
The findings suggest that people intentionally built and used fires differently depending on the season and purpose. One hearth was larger and thicker, likely reaching the highest temperatures. Researchers also found animal bones burnt in a fire with over 650 degrees Celsius temperature, which could indicate the use of animal bones and fats as fuel.
Lead author Philip R. Nigst stated that “fire was not just about keeping warm; it was also essential for cooking, making tools and for social gatherings.” The research sheds light on an important technology developed by humans during this period. However, more evidence is needed to solve the mystery of pyrotechnology during the Ice Age’s peak.
