This account tells us that ancient humans may have tamed fire 1 million years ago

According to a report by science alertthe mastery of fire would have allowed access for the elderly “to whole new worlds”. It revolutionized the lives of the ancestors by making their daily lives easier and better. However, nobody knows how or when this championship took place. Remains of burned materials indicate that this is where the use of fire began 1.5 million years old.

In recent research, scientists have used a artificial intelligence used as a spectroscopic thermometer. This technology is able to estimate the heat stress on rocks and fossils.

Researchers used AI to detect an area from the Younger Palaeolithic of Israel, about a million years old hidden traces of campfires.

Subtle chemical signatures?

Visual cues are essential to identify traces of fire in archaeological sites. Zane Stepka and his colleagues at the Kimmel Center for Archaeological Science used the thermometer Flint artifacts dated 1 to 0.8 million years ago, from a place in Israel. The artifacts were discovered alongside animal fossils in yellow-gray sand and on red silt, with no evidence of the use of fire.

But according to a report by Email onlinewould have indicated the thermometer subtle chemical signatures. Several stone tools and pieces of animal tusks are said to have been partially heated to different temperatures over 400 degrees Celsius. Investigators assume they came into contact with the fire.

Early hominins controlled fire

According to the team, the Forest fires cannot be ruled out. However, this is indicated by the grouped tools and bones and the fires confined to the camps early hominins controlled fire. The discovery of a handful of archaeological sites with traces of ancient artifacts and burn marks reinforces this idea.

The researchers believe that further exploitation of this new approach could help them learn more about it “the spatio-temporal relationship between the first hominins and fire”. A re-evaluation of artifacts found at other Upper Palaeolithic sites, including those in the Levant, would help.
