Prehistoric Hearths Reveal Ice Age Hunter-Gatherers Were Masters of the Flame

Scientists generally accept that the fire is very important to live in the last ice age, which has surprisingly little evidence from the coldest years in Europe, 26,500 and 19,000 years ago.

Learning centers from three to Ukraine, the research team acquired a new idea because the fire was used in the toughest period of the ice age. As a learn The beginning of this month this month reveals the introductory pyrotechnology instructions, including the potential use of the bi-bi-bi-bihearms, including the potential use of oils for bones and oil.

“The fire was not only hotter; was important for cooking, tools and social gatherings,” Philip R. Nigst, one of the leading authors of the study and a university in Vienna University in Vienna University statement. Although the archeological record confirms the fire in the upper paleolithic period (45,000 years ago) in the upper paleolithic period in Europe, there are about 7,500 years of space over the ice age.

“We know that the fire is widespread before and after this period, but there is less evidence of the height of the ice age,” said William Murpree, another leadership and a geoarchaeologist at the University of Algarve.

Now the new evidence from Ukraine helps fill this gap. Researchers examined three ancient hearths of the heart of the last glacier. In 2013, the ancient hearths drilled on the ‘9 archeological site, when the most history has the most in history by 21,000 years ago, suggest a unique idea that the people of the ice age use fire.

They used geoarchaeological methods such as scientists Microstratigraphic analysis (Geographic layers are a technique for learning high resolution), micromorphology (Land and sediment study of the microscopic level) and Colorimetric analysis (a technique for detecting chemical compounds).

Analysis, more than 112.12 degrees of fires (600 degrees Celsius), the European hunter has a deep knowledge of the fire building (hot flames) Burning more efficiently). Although all three fires are open and straight, researchers suggest that they are deliberately established and in different ways depending on the season. For example, the fact that a hearth is bigger and thicker, it was probably the one who reached the highest temperature.

“People knew the fire perfectly and knew how to use the fire in different ways depending on the purpose of the fire. However, these hunters used the same place during the annual migration of the year,” he said.

The work of researchers shows that the fires are fueled mainly with a spruce tree. If confirmed, the use of animal bones and fats would be higher than the higher pyrotechnic expertise than previously supposedly. “We are currently being used as fuel-accidentally burned,” Bosch said.

The study sheds light on one of the first and most important technologies developed so far. The previous place of the third date is not enough to close the cavity of concerns in the archeological record, and therefore the secret of pyrotechnology remains unresolved during the summit of the ice age.
