The Mystery of Fire: When Did Humans First Master Its Use?
Written on
Chapter 1: The Dawn of Fire Mastery
When did humans first begin to control fire? Recent discoveries by Israeli researchers suggest that the use of fire dates back at least 800,000 years, supported by findings on ancient flint tools.
According to Greek mythology, Prometheus played a pivotal role in humanity's creation. Observing that humans were frail compared to the gods, he stole fire from Helios and taught them essential skills like cooking, metallurgy, agriculture, and literacy. This act infuriated Zeus, who viewed fire as a divine right.
The mastery of fire represented a significant milestone in human evolution. While the myth is captivating, it does emphasize the fundamental role of fire in human advancement, facilitating technological, economic, agricultural, and industrial progress. However, the exact moment when early humans first utilized fire for specific purposes, such as cooking, has remained elusive—until now. Thanks to advancements in artificial intelligence, researchers have made strides in unraveling this mystery.
Section 1.1: AI Unveils the Secrets of Fire
Scientists had long speculated that the advent of fire usage might have occurred around a million years ago, a theory lacking concrete evidence. Previous assumptions were based on anatomical changes in early humans, such as reduced jaw sizes and smaller teeth, which some scholars believed indicated a shift to heat-treated diets.
In June, the journal Proceedings of the National Academy of Sciences published a groundbreaking paper detailing the analysis of ancient flint tools. These tools exhibit signs of fire usage dating back 800,000 years, discovered in Israel. The research team employed spectroscopic analysis to ascertain the timing of fire use, but the data was complex, leading them to enlist the help of artificial intelligence.
Subsection 1.1.1: A Technological Breakthrough
The AI program was designed to differentiate between heated and unheated flint, even determining the temperatures reached during heating. Filipe Natalio, an archaeologist and biochemist at the Weizmann Institute, humorously recalled that when they began their project, some archaeologists at the Evron quarry site doubted they would find anything new.

Section 1.2: Evidence of High Temperatures
The Evron quarry was first uncovered in the 1970s, with artifacts ranging from 800,000 to one million years old. However, no evidence of fire had been documented until this study. The analysis revealed that 26 flint tools showed signs of exposure to extreme temperatures, reaching up to 600 degrees Celsius.
Previously, archaeological consensus placed the onset of fire usage around 500,000 years ago. This new discovery challenges that understanding, suggesting that evidence of fire use may predate our earlier theories. The anatomical changes in early humans occurred even earlier, around 3 million years ago, raising questions about whether older evidence of fire will ever surface.

The Capstone mission has launched, set to explore the orbit of the future Gateway lunar station. This compact satellite, measuring just 34 x 61 cm, was propelled by a small Electron rocket, standing at only 17 meters tall, demonstrating a low-cost initiative at just $30 million.
