This report tells us that ancient humans may have tamed fire a million years ago

According to a report by ScienceAlertThe fire mastery He would have allowed the ancient mortals access To whole new worlds. It has revolutionized the lives of grandparents by facilitating and improving their daily lives. However, no one knows how and when this mastery occurred. Remnants of burnt materials indicate that the use of fire began there 1.5 million years.

In new research, scientists used a artificial intelligence It is used as a spectrophotometer. This technique is able to estimate the exposure of stones and fossils to heat.

Researchers used artificial intelligence in an area of ​​the Lower Paleolithic in Israel, dating back nearly a million years, to detect Hidden effects of campfires.

Hidden chemical signatures?

Visual clues are essential to determine the effects of fires at archaeological sites. Zane Stepka and colleagues at the Kimmel Center for Archeology used the thermometer Flint artifacts, dating from 1 to 0.8 million years agofrom a place in Israel. The artifacts were discovered alongside animal fossils in yellow-gray sand and red silt, with no evidence of fire being used.

However, according to a report from Online mailHe would have revealed the thermometer Fine chemical signatures. It was said that many stone tools and animal tusks were heated to different temperatures, and some were heated Exceed 400°C. Researchers assume they have been in contact with the fire.

Early hominins controlled fire

According to the team, Forest fires It should not be excluded. However, tools and bones grouped together, as well as campfires confined to camps, suggest that Early hominins controlled fire. This idea is reinforced by the discovery of a handful of archaeological sites that show traces of artifacts and traces of fire.

The researchers believe that further use of this new approach could help them learn more about it The spatio-temporal relationship between early hominins and fire. Reevaluate Archaeology Discovered at other Lower Paleolithic sites, including those in the Levant, would contribute to this.
