During the last ice age, our ancestors relied on fire to survive the harsh conditions. Evidence from a prehistoric site along the Dnister river in Ukraine reveals that people living during this time built various types of hearths using wood as their primary fuel source, with possible additional use of fat and bones. A recent study published in the journal Geoarchaeology sheds light on how Homo sapiens in Europe during the Upper Paleolithic period utilized fire for cooking, tool-making, and social gatherings.
According to Philip R. Nigst, an archaeologist at the University of Vienna, fire was not just about staying warm but was a crucial element in the daily lives of ice age hunter-gatherers. However, the lack of evidence from the coldest part of the ice age has made it challenging for scientists to understand the full extent of how fire was used during this period.
The recent study analyzed three hearths at the Ukrainian site, revealing that the fires reached temperatures exceeding 1,112 degrees Fahrenheit (600 degrees Celsius). This indicates a sophisticated mastery of pyrotechnics by the ancient inhabitants, despite the extreme environmental conditions they faced. The use of wood as the main fuel source, particularly spruce wood, was confirmed through charcoal analysis, with the possibility of animal bones or fat also being used to keep the fires burning.
The construction and use of the hearths varied seasonally, with one fireplace being larger and thicker than the others, suggesting it could reach higher temperatures. The researchers believe that the ice age hunter-gatherers had a deep understanding of fire and its various applications, adapting their use of it based on their needs throughout the year.
Despite these new findings, many questions remain unanswered, such as why there is limited evidence of fireplaces from the last ice age. William Murphree, a geoarchaeologist at the University of Algarve, wonders if the evidence was destroyed by the freezing and thawing of the soil typical of ice ages, or if alternative technological solutions were used instead of fire.
The research team hopes that further exploration of the role of fire in human evolution will provide insights into how it contributed to the success and dominance of our species. Understanding the ancient use of fire not only sheds light on the past but also offers valuable lessons for our present and future.
